Hi.. I am having a major problem with my machine.. I cut wood signs and use Vcarve with Mach3...
The Vcarve preview looks perfect, get it to the machine and zero out all the axis's and it always does not center to the work piece.. it runs off center by .25 possibly .5 sometimes... It ruins every piece of work I do .. I just did a sign with a vcarve border then a .125 offset from the border where it cuts out the sign from the workpiece... The top is fine but the bottom cuts all the way into the vcarve outline and ruins the piece...
Romaxx says it's a programming problem and no one at Vcarve forums have an answer... Where could this problem be in Mach3?
Thanks for any help... I am new to cnc and this problem is ruining all my work...

Just a couple of suggestions...
Thoroughly check the mechanicals of your machine (loose grub screws, binding or tight spots on linears or screws etc.).
Reduce your Velocity and Acceleration settings for the X and Y axes by 50% in motor tuning and save the changes and see if this cures the problem.

"Thoroughly check the mechanicals of your machine (loose grub screws, binding or tight spots on linears or screws etc.)"
Thanks for the help...
would the above cause a loss of steps? I should have also said the mill returns to Zero with no problems...
Thanks for help and suggestions because unfortunately this venture is not working at all for me other then creating fire food at this point...

" I just did a sign with a vcarve border then a .125 offset from the border where it cuts out the sign from the workpiece.."
If your v-carve border did in fact cut properly and the preview in V-Carve looked correct for the cutout then the problem is not with V-Carve or Mach3 it is your machine.
Did you reduce your speed and acc by 50% as Tweakie said?

Thanks Ray...
If your v-carve border did in fact cut properly and the preview in V-Carve looked correct for the cutout then the problem is not with V-Carve or Mach3 it is your machine.
Well the sign looks fine up until the actual cutout from the work piece... Like I said, there is a vcarve borber line that round around the sign by .125" that is because I offset the vector to outside .125" and then use that offset outside vector to outside through cut the piece for the sign shape.. Hope that makes sense..
Now that outside through cut looks great on the bottom half, but on the top the bit runs in all the way to the inside vcarve vector and clearly ruins the piece..
That looks like it is the machine?
Again, I have tried many times to center a cutout on a piece of material and it always cuts it off centered.. I have checked this and double checked many times with the same result... A entered piece in Vcarve coming out offcenter on the workpiece for a basice square through cut...
Did you reduce your speed and acc by 50% as Tweakie said?
I have not got back to the machine yet but will in a bit and post if it helps..
Thanks for all help!
-
I was just looking at one of my centered cutout failures and noticed that one of the corner radius's (I used a .250" bit) is much less then the other 3 radius's ... This was an inside through cut .. Seems like all 4 corners should have the same radius no? The one corners is at least half the radius size...
could that give a clue?

Reduce your Velocity and Acceleration settings for the X and Y axes by 50% in motor tuning and save the changes and see if this cures the problem.
Okay, finally got on the machine today to do some tests and Tweakies fix above seems to have made a difference.. Not perfect but it closed the offset the machine was running a lot and the milling ran much much closer to center of my work piece... still not perfect though.. Do I just tweak these setting until they are perfect? Was running about .25" off and now about .0625"
Thanks for the help!
-
There is a lot of 'trial and error' required to get each axis Velocity and Acceleration to their optimum values.
This is what I would do...
Just one axis at a time - increase Vecocity until the axis stalls on fast jog (shift + arrow key) reduce velocity by 30% and save changes. Do a similar thing with Acceleration.
Tweakie.
-
well today did not go so well.. was hoping to finish getting this thing working ...
The fast jog used to "bottom out" when I first got the machine but it does not seem to do it anymore even at 100% jog and shift...
I doubled the Velocity and Accel and the jog it would not stall out....
I took last nights setting of cutting the Velocity and Accel in half and took 25% off that since it was close last night.. That produce a horrible result which did not even complete the rectangle...
I brought the settings back to the half mark to do another test cut and wile the X axis remained .0625" off from center the Y Axis was back to .5" ....
so I am once again lost and not sure what is going on or happening, especially why last nights results at half the setting produced one result and today they produced a totally different result...
Thanks for any help...
-
Duh.. Okay...
I only reduced the setting by half for the Y axis and not the X axis... so that should get me back to where I was last night.. But it is still .0625" off and I cannot get the axis's to stall out through jog...
any ideas of what I can set the velocity and Accel to from here to get me closer? Like I said, I cut them 25% from the half setting and it was a mess...

Can I ask what your machine setup is?
Starting at the machine,
What leadscrew pitch do you have for each axis?
What stepper motors are you using (model no)?
What microstepping have you set for your drives?
What voltage is your power supply feeding your stepper drives?
Can you paste your XML file here (may need to rename it to *********.txt for it to upload)
The questions that it will answer:
What units the machine is set to run in
How many steps / unit you have set the machine up with?
What Max velocity you have set?
What acceleration you have set?
What step and dir pulse width you have set?
What lookahead you have set?
Have you set CV to turn off on certain angles?
CV turn off lookahead steps?
What kernal speed you have set Mach to?
-
Can you post your .xml file ??
Rename it something unique (ie. Jackson.xml) before posting.

I am not totally sure to many of these questions... I will go over them and report back.. With my machine I received an XLM file to paste into the Mach3 main file.. I have just been running the machine with these settings.. This is the only problem I have had so far...

Initial comments...
On your motor tuning page you have no pulse width set for your step and direct.... Are you using a motion controller or the parrallel port?
Your machine is in inches, and you have a X, Y and Z set at 5833 steps / inch, and the machines maximum velocity set at 160 inches / min.... so, i'd suggest
changing your machine kernal speed from 35kHz down to 25kHz.... given 5833 x 160 / 60 = 15.5khz (maximum step speed).
I'd also suggest changing the step and direct pulse widths to 5usec (which would be 100kHz and seems to work with most stepper drivers quite well).
I'd also suggest changing the lookahead on the configuration page to 200 (2nd column from LHS).
The 5833 steps per inch is confusing me a little .... as I'm not sure how you worked it out as it does not seem to align with either a metric or imperial pitch (unless you've got gearing on the machine)
either (1 / 5833) x 200 = 0.034287673..... (bit of an odd number... indicating it may be a metric leadscrew pitch... but)
5833 / 25.4 = 229.6456929133 .... again... little odd number
1 / 229.645.... x 200 = 0.87096908
so maybe a metric pitch of say .... 1.75mm threaded rod.... (on 1/2 stepping mode) ... still a little off
If it is 1.75mm pitch threaded rod... it should be 5805.714285714.....
[I've never done it... but if you have metric leadscrews, it may be beneficial to set them up as such, and then add a "G20" code to the initilisation string on the config window and also prefix your code with a G20 code so that the machine will appear to be an imperial machine and it will do all the correct math internally with minimal rouding errors ... maybe worth a consideration / comment by some of the more experianced about as to whether this would work]
-
Nice work Rob - one thing you forgot to mention...
Config. / General Config. - uncheck 'Use WatchDog' ;)
Tweakie.
-
Thanks Tweakie
...I am at work so it was a quick check...
I was seeing some off numbering for the ports and pins and axis settings but suspect it was me as I looked at the XML file and couldn't see them (think it happens when there is a conflict on the ports and pins if they are shared or listed twice sometimes... I'll review later)
We just really need to try to understand your machine a little more... Photos sometimes help if you are not sure about what it is, or to get an idea of the gantry weights etc with regards to acceleration.
-
Hi Rob,
There are a few duplications of pin number allocations but I don't think they will cause a conflict during Mach3 operation - but I am always eager to learn.
Tweakie.
-
May I ask....
What are you using OEM Trg #1 & #2 for?
You have used port 1/pin10 and Port 1/pin11 twice...
You have mapped your E-Stop and OEM Trig #1 to port 1/ pin 10
You have also mapped Input #1 and OEM Trig #2 to port 1/pin 11
What are you using Jog A++ / A-- for? (no pins assigned but are using a hokey 45 & 46?)
Why have you set output #3 and output #5 to share port #1/pin 14?
And Output #2 and output #6 to share port #1/pin#16
Do you have two parallel ports?
(given you've listed output #1 as port 1/pin1, and output #4 and port#2/pin1?)
[edit: you must have as you've got encoders setup and mpg on port 2]
You also have Charge Pump & Charge Pump2 sharing port 1/pin 17
.... again its quite hard to review a system that we can't see and don't really understand.... but there is probably a few bits there for you to think about.
I'd suggest only ever use one pin for one thing (although I'm no Mach3/4 Yoda / Guru by any stretch of the imagination) .... if you need to do something else with that output ... then run an M-code, macropump or brains.... I can help but need to understand our setup or what you're trying to do.
Rob

Okay,
Thanks for all the help...
First thing... I did not create the XML file it comes with the machine and load it into Mach3 file replacing the stock file for the machine settings...
The machine uses a Dewalt 611 router and works mainly with standard router bits on wood...
The machine uses ballscrew/leadscrews
Here is some written files that come with the machine:
Motor outputs:
X axis Port 1 Step pin: 2 Direction Pin: 6
Y axis Port 1 Step pin: 3 Direction Pin: 7
Z axis Port 1 Step pin: 4 Direction Pin: 8
Inputs:
Estop Port 1 Pin 10
Cycle Start Port 1 Pin 13
Feedhold Port 1 Pin 15
Motor tuning:
X, Y and Z axis: 5833 steps per inch.
Velocity: 160
Acceleration: 3
Thanks for the help! I am new to this and really a bit lost on all the Mach3 setting stuff...
-
What about all the other stuff? (Encoders and mpg, 2nd parallel port, OEM triggers etc)
Are you able to measure the leadscrew pitch... Are the ballscrews or threaded rod?... Number doesn't look right to me as far as steps per inch
Have you got access to the stepper drives, can you see any dipswitch settings?
What type of machine is it (manufacturing link... Photo)?
The setting up stuff is easy... Just got to start with the basics.
-
What about all the other stuff? (Encoders and mpg, 2nd parallel port, OEM triggers etc)
Not using encoders, mpg or 2nd (close loop) parallel port have to check OEM triggers
Are you able to measure the leadscrew pitch... Are the ballscrews or threaded rod?... Number doesn't look right to me as far as steps per inch
I am not sure if I cna measure lead screw pitch or how to do it... They are called ballscrews but it is a thread rod on each side running up the machine....
Have you got access to the stepper drives, can you see any dipswitch settings?
Yes.. I have been in the electronics , I will have to check again as I was in for a fuse but took a brief look at the stepper drives...
With all that said... the reducing Accel and Velocity did make a big difference in the problem by cutting them in half... It is just running slightly off now...
The machine is a Romaxx WD-1 I attached a pic
Thanks for all the help! I am using the machine for certain things, but for other things I need it to be precise I cannot use it...
-
Damn, that is a nice machine, and very well documented too!
http://romaxxcncrouters.com/romaxx-cnc-router-wd-1
http://romaxxcncrouters.com/cnc-downloads
I guess the most obvious thing to check is are you using one parallel port or two?
Forget about the ballscrews, I'd say they have got it right (considering the good construction quality of the machine).
The break Out Board Schematic for the machine is here:
http://romaxxcnc.com/boencboschematics.html
Port 1 / Pin 1 - Output Relay 1
Port 1 / Pin 2 - X Step
Port 1 / Pin 3 - Y Step
Port 1 / Pin 4 - Z Step
Port 1 / Pin 5 - A Step
Port 1 / Pin 6 - X DIR
Port 1 / Pin 7 - Y DIR
Port 1 / Pin 8 - Z DIR
Port 1 / Pin 9 - A DIR
Port 1 / Pin 10 - not denoted, but presume E-Stop! (it is referenced in the zipped XML file download (link below + text file within)
Port 1 / Pin 11 - Cycle Start (button on front plate)
Port 1 / Pin 12 - Feed Hold (button on front plate)
Port 1 / Pin 13 - A Channel [MPG?]
Port 1 / Pin 14 - Output 2 Relay
Port 1 / Pin 15 - B Channel [MPG?]
Port 1 / Pin 16 - Output 3 Relay
Port 1 / Pin 17 - Output 4 Relay (Actually The Charge Pump Circuit!.... see text file in XML setup / zipped folder!)
Presume no encoders so ignore port 2 pins.
Their XML setup files are here: http://www.romaxxcnc.com/RomaxxCDplusplusB.zip
Attached is an XML file I edited looking at what the manufacturers wiring diagrams and following a read of their text files.
>>> I normally do not edit XML files for people in case everything goes horribly wrong and we are all responsible for our own actions!!!!<<<<
Use this XML file at your own risk!
I would suggest jogging the machine to a central location (1/2 way in all directions X, Y and Z), then load the XML file into Mach 3, by reloading Mach3 using the "Mach3 Loader" option, whilst having your E-Stop depressed on the machine.
Have a look at the XML file and try to understand what I've done (you have a nice machine, and I'd hate to break it!
All the step and direction signals are as per the manufacturers schematic (link above) as are all the inputs and outputs.
I've got rid of all the duplications and port 2 references (as I presumed you have no encoders on the machine... other than maybe the MPG and the run and stop buttons on the front of it). edit: read your comment later... read my suggestion below about limit switches + a probe input! (taken a little while to write and edit the xml file...)
I have also programmed in the Run and Stop Buttons to the appropriate OEM Trigger Input pins and set up the corresponding OEM Button Codes. (on the system hotkeys menu)
I've also been through the config screen and setup the lookahead, the initialisation script (it will set you maximum feedrate to be correct to align with the manufacturers max velocity).
I've also setup the step and direction pulse widths to "reasonable" / common numbers (think of them as teeth on a cog.... the bigger they are the better they are seen by your stepper drives [up to a point!])... you have zero in here before and I suspect that this along with the lookahead was probably your problem, and maybe the ports and pins being shared.
I've also set the machine to go into E-stop at programme end on the config screen (or M30 or rewind).... I find it helpful.... just press the reset and you can re-run the code.... it ensures that the machine won't do anything strange at the end of the cut.
One thing that does concern me about your machine.... no limit switches or homing switches or even a touch off probe for setting the tool offset / length following a tool change ..... (think the manufacturer missed that one sorry... not very good in my opinion [personally])
I have removed the encoders (except for the MPG.... and did not change its settings as I presume the manufacturer put the settings in correctly).>>>> In hindsight.... I saw your comment on your last post... not using MPG.... if It were me.... I'd use one of the inputs and put some homing and limit switches on the machine and a touch off probe for offset (see my other comment.... if you want help setting these up just ask).
And I changed the kernel speed to 25kHz (your steppers are only running at slightly less than 16kHz... you don't need any more than that).
If you have not done so already, I'd check you are using the right version of Mach3 which seems to be generally accepted to be version ... 062 and not 066.... available for download from here: ftp://machsupport.com/Mach3/

Wow Rob..
Thanks so much for all of that and the great information!
The 2nd Parellel port is for the addition of a Closed Loop which I did not add (yet) it can be added at a latter date...
The unit also has 2 standard outlets for dust collection and the router...
The MPG can also be added later and even the 4th axis (but the machine has to go back to him for that)
I actually did want to get the touch plate and was wondering how to go about it.. How difficult would it be to do? I am okay with learning things but am very knew to all this and a bit lost..
I can't thank you enough for all the help!
-
No problem, glad to be able to help.
You may consider sending an email back to the manufacturer and showing them this link / discussion. They obviously spent a lot of time developing the machine and putting together the total package, including their XML file, and I'm happy to have a discussion with them about the changes to the XML file and provide pointers as to why I looked at it that way (at the end of the day I'm just a passer by with a keen interest in cnc and have a couple of personal cnc machines now... going to convert my other mills and lathe to cnc too). I was just really baffled why they'd doubled up on some of the pin refs, and also the OEM Trig was done another way (could have a brains or macropump to do the same thing as well....
If it were me... I'd add a touchplate and combined home limit switches (two input pins required)..... and I'd use the MPG pins on the breakout board to provide them. In my opinion you don't need an MPG fixed to the machine.... I'd buy a Contour Shuttle Pro (either new / via ebay)... I have one personally and they are great work with M3 + M4 and all buttons are fully programmable.... you will wonder what you did before it? (you could also build a custom keyboard with hotkey buttons / keyboard emulation or buy a VistaCNC pendant too.
Limit switches... I thought I'd never need them.... until I had a machine crash when it was running unattended doing a probing routine .... I was lucky that it was not using ballscrews but a timing belt drive (4'x4' plasma table).... Fitted them shortly afterward.... never a problem again and I use them to home and square the axis too (I have a slaved motor which your manufacture has well avoided).
Probe... all you need is a ground clamp and a Bob Input Pin from the bob on crocodile clips with a bit of single sided PCB ..... basically Bob Input pin to the top side of the PCB... and crocodile clip gnd to the tool.... .... need to set up the probe input on the ports and pins within Mach3 inputs....
4th axis will not be difficult.... you just need a 4th axis + stepper motor + driver and some means for the 4th axis to be driven by the stepper motor (I use a HV6 rotary table with the plasma and an adapter).
Rob

well the problem is solved! Everything you did worked and ran great!
I can't thank you enough.. I really do want to add the touch plate really bad...
What parts do I need to get started with that and how difficult for a newbie would it be?
I love the WD-1 and the help and support has been great... I will let him know that the problem is fixed and send him the thread...
I am not sure about your questions as to why he did certain things certain ways.. I do know he has the second port set up and ready for a closed loop upgrade, I just could not afford it.. I actually broke the bank on this (first )cnc...
I was going to get a cheap China made one but was worried about starting out without support (boy was I right)
Me and my wife are thrilled this thing is running perfect and can't thank you for all your help enough..
I owe you dinner and beer anytime!
Also thanks to Tweakie for aiming me in the right position...

Pleased you have it sorted ;)

Hi Guys
I am very new to the forum and CNC scene so please bear with me..
I am having a similar issue wit my machine (3 Axis router) I do not know much about coding.
I am using Mastercam X9 and MACH3 to host my machine
I am getting this error when posting the G code ??
I dont know if this could be related to my machine starting of fine and then slowly as it moves on the it starts to cut skew as if the ZERO mark is moving. Just the X axis does this.
The machine hase 2 what looks like Chines stepper driver and one gecko drive tis is the x Axis one and it gets hot, I made a heat sink for it to absorb some of the heat but this did not solve my problem, I am sure that the problem must be in the code.
I have checked mechanical stuff like backlash etc.
when in mastercam the operation looks fine.

any help would be appreciated.

Not got a clue about the code... Are you using the right post-processor from matercam to mach3?
For the stepper motor getting hot that is probably a current setting or wiring issue or failed drive
How about posting you XML profile file (give it a unique name)... And provide info on your stepper motors, their drive settings etc.... Photos .... More info is better than none
-
yes stepper motors are getting very hot, thought that would be because they are working a lot but it is really hot, can not keep my hand on it for more that 5-10 seconds? what XML file ?
-
Steppers, like any motor can run warm to hot.
"Hot" has a lot of range in it and it is very subjective.
My hot to touch may be different to yours.
I'd suggest checking all of the settings are correct and in line with data sheets.
The profile XML file is where all your machine settings are saved.
Go to the C:\mach3\ folder, sort by filetype
Scroll down the bottom... XML files and there should be one that matches the profile your machine is running with.
If you are unsure, start mach3, and when the screen loads, normally in the bottom RHS there will be a text box with the profile name in it.... Your XML file will have the same name

Heat shortens the life of anything really,

O ok, I know what it is, I will post it when I get home, I am not that much worried about the heat of the steppers at the moment but I am about the Drivers, I think that this could be my problem to the off center.. But I think that if it was the heat that causes the movement to be off it would have been irregular, but it is not, it just works skew, the thing that boggles my mind is that when I run a G-code rough cut it all looks fine. then when I run a finishing program for the same job it starts fine but progressively moves in the X+ direction ?? puzzles me .
