Title: Z home goes past 0.0 to +1.0
Post by: ttm on January 27, 2012, 04:10:02 PM
hello, I can not stop my Z axis from going +1.0 when I try to take it to 0.0 it always goes past 0.0 and the dro readsz +1.0 (past work top)

I can lift the axis, push zero, the dro will read sero, and if I push go home, it moves the Z axis past 0.0 again to +1.0
can someone help me with this, it seems to have started doing this out of no where,

please keep in mind, I am still in setup of this kmachine, but it did work at one point

Thanks!

Go Home? Not sure what you mean but likely that is either a button that references the machine or sends it to machine coords zero.

yes on the programs screen there is a button, go home, it would take you to where I had zero's all three axis at, now it sends the z axis past the 0 point +1.0 and that dro reads +1.0

Ok do you have home switches? If not then try this, move to zero position and then press RefAll then see if the Go Home button takes you to that zero or still moves higher.

Ok do you have home switches?

there are but they have not been setup yet,

I do not have a ref all, but when I hit ref x,y it went past 0.0 and hit reset and when I hit ref z it wenbt past that and hit reset too


and once this happened I put the head in the center of the table about three inches off what would be the work suface, and zero's all three axis there, also +1.0 moves the z axis down to the table, I had it on the work piece, it was a good thing it is a floating head

Post by: ttm on January 27, 2012, 05:15:27 PM
it is like there is a setting somewhere referencing +1.0 on Z axis, but I do nto see one anywhere

by the way, thank you for your help!

Post by: BR549 on January 27, 2012, 07:20:25 PM
OK first you have to realize that Home and zero can be 2 different things.

If you are just moving to a location and press zero you are just resetting the local Zero position. That has nothing to do with HOME wich is a machine reference position Machine Zero.

IF you do not have home switches then Mach set HOME to whatever is current WHEN you first fired up Mach3. It just happend to be at +1.00 when you did it. IF you can find a button called RefHome it will reset the machine Zero.

There IS a proceedure for setting Machine Zero( HOME) without a home switch.

I take it that this is a plasma rig ??? and you are using the CandCNC stuff????

iok, I do keep getting home reference mixed up, let me explain what is happeningbetter

when I have played with this before, I could move the axis to a position, then zero x, y and z axis, I could move the axis anywhere on the table, then hit home and it would take it back to that location I had zeroed out, it will still do x and y, but Z will lower right past zero and go +1.0 further, then stop.

never hitting any limit switches, or home switches, which I have yet to get working.

yes, this is a candcnc unit, -plaspakIII mp3000 ubobII DHTC, servo motors, I do not have the torch on it right now, I am trying to learn how to run it until I get that part repaired, as I want to convert it to router as needed , so right now I am working without the thc sensor on the machine
I am and have been pretty confused about this

thank you very much

My I ask another question about your second pic the program screen?  I see most all of yours are lit, mine are not, I see you have mp3000 loaded, is it a plaspakIII with ubobII? I can run snagit to capture a scrolling screen set and get all my settings if needed, which if someone had the same setup as mine, I would love to compare,

There were 8 different screen sets with the download.
All of the yeller screens do not have a GO HOME button (that I could find).
All of the screens that have the GO HOME button (that I could find) have the same Z1 code in it.

The only other thing I see that is on the Yeller screens is the LOAD MATERIAL button which would do similar, but is not what the OP is mentioning.

The yeller screens DO have a GO HOME button ... on the SETTINGS screen but it is OEM 138.

I did some of the captures from Screen4, some on simulated profiles so what is "lit up" is probably irrelevent.

Did you recently dwnld anything new ? Or update your screens from the CanC site ?

mine have a go home, I just pulled up the dthc load as well, and it still does the same thing,  I am not aware of any new screens I have put i , I did reinstall, but sure I did not have this issues afterwards,  I have watched every move with this machine with finger ready to hit estop as I have no limit switches hooked up

next step!, I have a teszt file called roadrunner but it is a 3d AZs it is trying to move the z up and down, is there a tst file i could mount a marker to the tool just to see it follow a pattern?

I know, I have a long way to go to worry about that, but i'm 50, ya know and this is making me feel like I'm 12 wiht a new toy - and yes this is for the business not a toy, and my wife will make sure of that! (big grin)

again thank you, I do not know what I did to make that cange but I chaged it for sure!  there must be something wrong with the material load button as well, it does not move at all when I push that one

I noticed one of the LOAD MATERIAL buttons had a Script error (shows in the status line when you hit the button).
Some of these screens have script in that button to check the dro's on the Settings screen, some do not but contain bad script.
We can fix that later.

I think I am running the correct screen set, mp3000 my ubob is rev6b I am pretty sure it is ubobII, ya know what, I can do screen shots with snagit if you think that may help, what screens should I capture? all of the ones for mp3000-basic for the router? I know I am supposed to be running mp300-dtch-ubobII in the laoder for the plasma torch, but the thc sensor is at toms now, in fact I am going there the 7th and they are going to take  alook at all the equipment (run tests) and make sure I have what I am telling them i have
 
I do know it did work correctly, and have no idea why it stopped, I have along way to go, and to tell the truth, I have doubts I can do this at this point.  I just am not getting some of things that should be simple, and that is causing me to do the wrong things I think,

I sitll need to figure out how the homes work, then the limits, i think if I can figure that out, some of the problems I am having I will be able to take care of as I will then know what is causing them, phew, i think...

this is nothing like working on the old computerized cars

I did try the test file in sheetcams tutorial it all worked expect for it sent z axis -0 (travels up on my machine) til it hits the stop, after it drew part of the a (I put a marker on it ) but I think that will have to wait, i have a long ways to go before I start on sheetcam I think

I want to say thanks again, i have moved so much further today after getting that fixed, (well maybe not in some of you guy's standards), but I have moved along, it feels good, was actually able to get past my last issue, not sure where i read bout using a marker lightly attached, but that helps, at least I do not have to worry about damaging something

it seems some of you have the same controller Candcnc, so I will ask, how am I going to know if I have loaded the right screens for my setup?  I loaded right from the install file
keep in mind this is a couple year old unit as well
thanks

EASY , ASK TOM over at CandCNC to make SURE you have loaded the correct plugin and screenset.  There are several different applications on the install disk. With his systems they are highly integrated and you need to run the proper setup per hardware to get the BEST results and fewer suprises.

The good side is they are documented in his product manuals. Most just don't bother to read and study them.

then I have the right screen sets, and I have read his install manual several times now, some of the manual is a bit hard to get and put to use (at least to me it is), or something else is wrong with part of the equipment,
even following it step by step, i have even uninstalled and started over, i bought another computer eliminating any possible port conflict (this one only has one serial and one parallel port), that was not the issue,  as i have the same issues.

right now I would love to see someones pins and ports with the same system i have, but it can not be the new ubobIII from my understanding. 

And, I think my issues tend to be a bit fun as the previous owner had done a couple changes or upgrades to it. Pins and ports are different through some of the versions of hardware if i am understanding tom correctly. the machine does some funny things at times still and the input lights never seem to be what I am told they are supposed to be, right now I want to get it working without the torch setup, if I can do that, get he gantry to move where it is supposed to when it is supposed, get homes firggured out and limits in place, i will at least be making some progress.

 I have found after everyday for the last 3-4 weeks I can not do it without help.  I thought i could get it going, wow was I wrong.
buying a used system, that was pieced together (converted from practicalcnc), that supposedly ONLY not needed setting up parameters was not wise.
I do not even know what servo motors are on this table.  but i do have it running correct length if you manually enter in the mid scree

Terry,
Maybe we should  start a thread on the subject to explore it some. We live in a world of plug and play, but one must admit that it can be frustrating
when trying to grasp just one subject from what is documented.
An example relating to limit and home switches on documentation:
MANUAL                                                                      PAGE

USING MACH3 MILL                                                       4-8 to 4-11, 5.3,5-17,6-2, 12-1, 1-17
MACH3 CNC CONTROLLER SOFTWARE & INSTALLATION    4-9 to 4-15, 5-5, 5-6
MACH3 TUTORIAL (setting up a 3axis machine)                 11,12,13,14
CALYPSO MANUAL                                                         61
Lets not forget about getting off the limit switches  ( USING MACH3 MILL page 4-10)

ttm,
Above is worth reading and studying to understand. What makes this more difficult is the use of  a different screen set than normaly used  
and requires additional attention and information to get to the problem. You can thank the folks in here for going the extra mile spending
their time to find what they need to address the problem.

Remember that all this is supposed to be fun,

RICH

Rich, did I come across that I didn't REALLY appreciate the help?  I really have said thank you to everyone and I do mean it, heck I would still be trying to figure out why I was going +1.0 past my 0.0 on z if it was not for them posting about the button reference that can only be seen with screen4, I would still looking for for some setting on a screen, never even dawned on me to look into customizing any buttons settings.  Am I being a thorn?  if so I can step back some, I'm darn tootin happy there are folks willing to take their time to help. I really do not think I can do this on my own at this point.

I have looked at the manuals quite a few times, I'm just not getting it I guess. I have read the install manual  and tried to reference it as much as possibly to the mach manual, like I said i have been doing it night and day for weeks now,

again THANK you too everyone that is helping, you have no idea what a difference you have made in just this thread, I really need to get all the settings figured out, what they do, what they mean, and how to implement them, in my head and on the table.

I will look at those links agian, I did put full shots of my screen up and config files on a picsaweb page
just in case someone asks to see one I can send them a link


thank you

no worries, just want to be sure people know I DO appreciate the help!

I am about to start on homes, actually setting them up and working on my z axis issue, but I want to know i am talking in the right terms before I start asknig too many quesitons

Im waiting to get a few pieces of stock monday to make my limit brackets a bit differently than they were setup, I'm going to put them on the gantry one for y on the end and one for x in the center of the gantry, and use a stop on each end of those runs to activate the switch,

 but I can start on homes for table and material loading which I think I have an understanding on more today, and hope my plan is a good one.  now on to setting up home configurations, while I try to figure out my other issues


thanks for everything

HIYA TOM, IF you loaded the correct plugin/screenset from the CANDCNC install program THEN you should have all the correct settings to make it work. The only thing that needs setup is the SLAVE axis for the long axis. And then it should be to select the DIRECTION of movement.

The XML that comes with the install is correct for MOST applications and covers all the assesories inputs such as limits, home,etc for the standard setup of a machine.  

When I get back to the shop I will make a copy of the setup we use.

HIYA RICH, Not the case with the CandCNC stuff it is high documented as TOM created a very integrated package that is NOT like a standard MAch3 installation SO in turn he documented it VERY WELL with LOTS of pictures and diagrams and words.

The XML that comes with the install is correct for MOST applications and covers all the assesories inputs such as limits, home,etc for the standard setup of a machine.  

IOWS it has the correct pin setup for the serial and parellel ports to and from the pc to the mp3000 and to mach, I'm missing something then, a lot!

I um'ed and ah'ed before deciding not to delete the above tinyurl - we're all grown ups right and can make our own decisions. However, if you don't know what tinyurl is then before you click on it you may want to familiarize yourself with the potential risks. This is in no way any suggestion of mal-practice on ttm's part. I'm happy to accept that it re-directs to where he says it does. I do ask myself though why use tinyurl rather than post here?

well, it wasn't about using tinyurl instead of posting here, I was just trying to be considerate and not post a bunch of pics to this website that only references my setup, instead posting them to a picsaweb folder I created,  It is pretty common on other forums to use a link to pictures hosted elsewhere to save hard driove space for that forum,  I only used tiny url to make it a simple link, I have never has a problem with tinyurl, I could instead posted the link to save some basically wasted space on the forum,
the only reason i posted them to picsaweb was because to put them on my page, i would had to have created a web page just for them as my hosting sevice does not allow driectory browsing, and photobucket is so darn slow these days

sorry if i was not supposed to use tinyurl, you can delete the post.  if possible, or i can edit it and remove the tinyurl

Let me add, that if it had been something that would be good for other new users or just one or two, i would had posted directly into the message about it, but there were a bunch of them

thanks
Tom

actually I just tried to modify the post remove the tiny url link and just put a direct link (full web address), and it is too late, I can not modify now, so if you would delete that post, I would appreciate it

I will admit i did not read the forum rules fully, I know i am not going to do anything stupid, never once thought about posting a tinyurl, sorry!


Thanks!

Tom - please don't worry about it. I'm not aware of any rule that says you can't use tinyurl here. I just felt that an awareness of the potential risks should be pointed out to anyone who doesn't know what tinyurl actually does. Remember there's straight visible linking and there's invisible re-directing which is tinyurl's purpose. My apologies if I've offended you - that wasn't my intention. Just trying to help keep this a safe place.

oh no, you didn't offend me at all, I understand what you are saying, and really did not think about posting a link like that, I have only used tinyurl for places like this and a few emails, but I know who I am sending them to, ad they do me as well,

I've run into a whole new ball game with this now,  to top off finding a burnt up th sensor card, something fell from the z-axis that looks like a small bearing cage, I'll be taking that apart later today when I saw that, I looked at the bottom  and you can see where it had been slammed against the stop actually bending the bolts that hold the 1/2 thick plate on.

Back from Texas, the folks a CandCNC are really nice, it was a pleasure meeting them.  I have the table partially finished now, I have my home switches installed and a z axis limit switch to keep it from damaging the head again, and they work! z axis hits a limit, it stops the machine, click reset and override limit and you can manually back it off the limit, if you click go home, the gantry goes - to home switch x and y then backs up +.500, i will tune that in closer as this table does not have a full 8 ft of cutting travel for y axis,  ok it does, but the torch head has to be past the slats to get that length

anyhow I'm pretty happy about this! I have some ways to go yet in setup and have run into another couple issues trying to cut a file, but I think it is for another post

I just wanted to say thank you to everyone as every bit of information posted here and private messages has helped me in more ways than you can imagine!
