Title: Sound with out movement (JOG)
Post by: Lou on November 13, 2011, 12:49:47 AM
Hello I'm very new on this forum and indeed to the world of cnc Routers
My name is Lou and I have had a couple of post regarding my problem with jogging, however for some reason
I can't seem to be able to post on that thread, so i have started a new thread.

I purchased a wgit 6040 cnc machine on e-bay, I have purchase Mach3 soft ware and a second hand computer with XP windows,
so far so good. 

I then proceeded to configure the software to the specifications in the manual supplied with the machine.
I have configured the soft are as as per the attachments.

Now My problem is this when I push my arrow keys my DRO's indicate movement . All okay to this stage.
Next I turn on my driver and try to jog the axis on the machine, movement is indicated on the DRO'S but I get no movement out of the machine on any of the axis,
all I get is a grinding sound from my z axis motor as if its trying to move but its not able to or something is holding it back.

Please advise me, if should be doing something else or am I doing something that is creating my problem.

Regards,
Lou :( :-\

Hi Lou Might be stating the obvious but have you used the motor tuning config on X Y and Z axis on mach, sounds as if you are asking the motors to do to much or to little

Hi Jim,

I have configured the x, y and z axis is indicated on the attachments, the only motor that I get the noise from as if its attemptingf to jog is the z axis,
the y and X axis do nothing.

Hi Lou, I could not download your attachments, however I could not see the motor tuning page in you pictures. Its under config pull down called motor tuning. If you dont stick to the motor parameters they make terrible noises. I aint very good at CNC but that man Hood is if you can catch his eye on the forum. Jim

Can you attach your xml and I will have a look and see if I can find a problem with your config.

Hi Hood,
Pardon my ignorance, What does XML stand for?

It is your configuration file.
If you open Mach as normal and on the main page you should see the name of the profile you are using lower right of the screen. Next go to your Mach 3 folder and look for a file with that name and a file extension of xml.
Copy that to your desktop and rename it Lou.xml then use the additional options button on the reply page to browse and attach the renamed xml.

Hi Hood,
I opened Mach as normal and checked the main page as you said, Profile is showing "MILL"
Then you asked me to go to Mach3 folder!! Not sure how I find this folder to look for the file with the the name
file extension of xml.

It is where ever you installed Mach to, the default is C:\Mach3

Sorry Hood, I need lots of guidance, I think this is what you asked for in the attachment.

Dont see anything seriously wrong with the xml assuming the pins are correct (they are with the documents) Your acceleration on the motors may be a bit high though, try dropping it to 50 and see if it helps.

Hi Lou,

This may sound really stupid but you have "twisted to release" the EStop button on the front of your mini controller haven't you ??

Hello Hood and Tweakie,
Ye the e-stop button on the controller is or has been twisted. Okay hood i will attempt to reduce the speed on the motors.
Do I do do that in my configuration tab in motor tuning.

Post by: jimthefish on November 16, 2011, 06:03:11 AM
Hi Lou its Jim, yes, I did mine by going on the motor tuning page and dragging the sliders on speed and acceleration till I got my motors to work. Remember to save the settings before trying them. When I had them working to what I wanted I noted down the figures for future reference. Start of with slow movements and build up till they start to give you problems. Back off a littel as changing directions a top traverse speeds can cause failures. Good luck.

Post by: jimthefish on November 16, 2011, 06:26:30 AM
Hi Lou forgot to say watch out when dragging the sliders you will notice the graph numbers change. Thats how I could not get mine to work when I first set up the machine. I was on the highest scale  and the steppers could not handle the speeds I asked for. Jim

Post by: Lou on November 17, 2011, 04:47:08 AM
Hello Jim,

I have tried the sliders on the motor tuning, Still no luck in getting movement on my machine.
Jim at a loss at what to try next.

Please let me know if you have any other ideas !!
I'm also hoping that  hood might still come up with a possible solution to my problem.

Regards,

Lou  :'(

Just to recap, you get a noise but no movement from Z when you try to Jog and other axis are just dead, no noise or movement when you try to Jog.
Is that correct?
If so then you really need to start metering the port and parallel cable to make sure that is ok and if it is then its either a faulty driver/breakout or wiring wrong or pin assignment wrong.

Hi Lou Hoods your man to sort this out however a few thing to look at. My problems started by me taking the old wiring from my denford mill and assuming the colour coming out of the motor was the same all the way trough to the steeper drives (WRONG) so I ended up cross wiring  my X and Y drives, unlike you my stepper drive burnt out. Expensive error. My Z moved but the X and Y just melted the steeper drive, luckily your OK.
Lou they the following
On the diagnostic page look to see of there are any red lights on (overtravel and stops activated).
Check that the computer output is stable (if you look at the Resoursce on the MAch internet file and watch and listen to the videos on setting the system up it will tell you how to do that.
Check for loose connections you have made, my spindle kept stooping in mid program running, it was a loose wire going into the BOB.

From the sound of it you dont appear to have any power to your X and Y. as I said my machine conversion was from and old 1988 Denford Triac which had 4 wire steppers, if they are not matched in pairs that could be your problem with the Z axis as my axis grumbled the first time I wired it up. A simple electronic tested will tell you the pairs of wires.. Lou dont know how much you have had to do to connect it all up but it appears you havent got power to your X and Y axis.
Keep in contact with the forum and you will sort it out, I did and I'm as thick as two short planks when it comes to electronic. Got so many notes on how I set it up if it goes wrong I should be able to fix it, maybe with help from Hood. As I said before if not someone on the forum will help.

Hi Lou just looked at the machine you purchased off ebay, all my stuff about the motors is not relevant. Have a look on the diagnostic page and see if any of the overrides are stopping you moving the axis, failing that there might be something wrong in your blue box controller or as Hood says the rs232 or your computer outputs. I'm in the UK (Birmingham) so anything I can help with let me know I assume your in the USA. Jim

Hello Jim,

I had a look on the cnc zone site that recommended, the first video clip showed some movement at least, with my machine I seem to get a grinding sort of sound on the z axis motor and it looks as if its trying to move but something is holding it back.
I will be going away for the weekend, when I get back I will have another look at it and see if I can find something that might help.

I might also get back to the guy that I purchased the machine from (The Importer) a local person and see if he can shed some light on the problem.
I didn't realise that it would be so difficult to get the machine up and running. Never mind we will keep at it and I hope that I will find the answers. I will keep you all informed of the progress.

Regards,

Lou

Hello Jim,

Thank you for your continued help with my problem. I have just returned from a weekend away from my home and I'm back on the case trying to solve this mystery of mine.
Firstly let me tell you that I live in Melbourne Australia and not the USA as you may have thought.
 
Jim, Its interesting the manual that was given to me when I purchase my machine gave different set of 
confiruration figures for the motor tuning to the ones that you have made me aware of. Thanks for sending me this version and I have now tried the configuration in the manuel that you refered me to.

This was the result of the changes that I made after looking at the Manual that you asked me to look at.

Using the mouse and the pop out of mach3 3 to jog the cnc machine.

Clicking on the [X+] button - I get a grinding sound out of the (Z Axis) motor. Clicking on the [X-] button I get static movement on the (Y Axis). A Jerking type of movement,and very slow.

Clicking on the [Y+] button I'm able to hear a faint click in the motor of the (Z Axis). If I click [Y-] button I get a grinding sound in the (Z Axis) again as if its trying to jog, but no movement occurs.

Jim, I have just retried again, and its do different thing again. I now only have movement on the Y axis when Click on the [x+] button I jog to nearly the end of the table and then when I released the button, wan click [X-] button,
the machine jogged in the opposite direction back towards home.

It seems to have a mind of its own, doing different things at different times without  me changing any of the configurations details that I have put into place.

Would this be a controller box problem? would it be defective perhaps? or could they have assembled the thing incorrectly? could this be possible?
Lou

Hi Lou. as I said I'm no electronics person but I think it maybe a controller box problem (maybe a bad earth or a loose connection). If the bloke who supplied it is nearby contact him. Remember if you open the box and mess you might infringe the garuantee. As Hood once said to me if it comes from China and comes out of the box working chances are it will continue to work. If it don't work send it back or get in touch with the supplier. If I was a betting man (i'm not) I think you have controller box problems or your computer is not compatable. Jim

Lou,

Something Hood mentioned earlier. It may be a good idea to check your parallel cable for continuity to make sure it is good and that pin 1 connects to pin 1 and that pin 2 connects to pin 2 and so on. You would not be the first person to have a dodgy lead.

Hello Jim and Teakie,

Okay, thanks again, How do you suggest that I check that the parallel cable connections? to line up the pins?
Yep that's the other thing that I will do this week!! contact the seller and speak to him regarding this problem.

Regards,

Lou  :-[

Lou,

Use a multimeter set to continuity test or take the lead to someone with a multimeter and ask then to test it (check for continuity to make sure it is good and that pin 1 at one end connects to pin 1 at the other end and that pin 2 connects to pin 2 and so on).

Hello Tweakie,

Well you hit the nail on the head!! Faulty lead- Yep jogging away very happy now. Can you believe it!! its been driving me crazy to get this thing to jogging,
and with your suggestion  we found the answer to the problem. Thank you, thank you so much.

Now I start to learn how to drive this machine, Hopefully it will be great fun!!

I will keep in touch with the progress.

Regards,

Lou  :) :)
