Thanks Ivan,
  I got her back up and making chips. I actually do not understand this whole thing. I turned everything off yesterday after my failed attempts and left it for me and it to cool off. I fired it back up this afternoon and it working just fine again #@?*&!!! javascript:void(0);

They are belt driven servos. If that is what you mean, I'm rather new to this whole thing of CNC.

Thanks - bingart

General Mach Discussion / Herky-Jerky Z
« on: June 01, 2012, 04:50:49 PM »
After cutting 100 of the same piece without trouble, or change to any setting, the Z started plunging deeper on the piece. It would plunge to drill a hole and not lift up the specified amount. As it continued to drill the next couple of holes it wouldn’t pull up enough to clear the surface and would route a line leading to the next hole. I’ve tried turning everything off and restarting everything and I get the same issue.  I noticed when I was cutting the previous pieces that when the machine returned to the start position after completing the job the DROs for X & Y were not zeros so I would just hit “Go to Zero” and then start the next job.
  When it started ruining material I decided to check the steps on the Z axis and when I did, I found that the positive direction was fine but when I went in the negative direction it was off a bit. I tried going back and forth with calibrating the steps and could get close but not as close as I would like so I went in to motor tuning and stepped up the acceleration and velocity wondering if that might have some effect on the stepping. Much to my dismay the motor for the Z started to vibrate badly so I ran it to the limit switch and it stopped. After resetting the acceleration and velocity back where I had it (60 and 10 respectively) I got the jogging to slow down but it still vibrates badly even when no jogging is taking place. When you look at the motor it is just going back and forth rapidly causing the spindle to shake up and down until I either close the program or run it up to its limit switch.
  Is there anything you can tell me that might help?

Thanks a bunch - bingart

Brett, Did you try calling me earlier? If so, sorry I missed your call I was over at the table doing some final prep for cutting in the morning. I'll be around the rest of the evening if you want to try calling me again.

Thanks,

Bingart

I'm just about there. I just purchased my license today and ran the router through an entire cutting job without turning on the router. I'm waiting on some new bits and a new collet before I actually do any cutting. I checked all of the vacuums today and everything is working just fine. If you can tell me if there is a way to reprogram the GDP 333 drive to a higher Hz that would help too! It will currently only allow me to go to 300 Hz and from what I'm told that is about 18,000 rpm and I have some bits on order that are recommended to go up to 21,000 rpm. I really appreciate your help on this!!!!

Hi Brett,
  I'm back from vacation and was wondering if you had been able to look over the info that I sent you. Please let me know. Thanks,

Hi Brett,
  Here's some more info. I found a link to a Perske Router motor.      http://www.crpperske.com/pdf/CRP-063_PerskeMotorBrochure_F.PDF

If you look at the photos that I uploaded it appears to be a VS 50/60 motor. Take a look and see what you think.

Thanks again,

Bingart

Hi Brett,
  Thanks a million for the help. Here's what I have for documentation. I hope this helps. I'll be posting more as I can get it.

 I've searched this forum and the manual and haven't been able to find an understandable answer to help with setting up Mach3 to control my spindle. That doesn't mean it's not out there, I just need to be able to understand it. I've made all of the suggested setting changes that I can find. I can get the Output#1 to light up on the Diagnostics Page but I'm not able to get any control of the spindle yet.

I have a Perske 3 phase 3 HP spindle that is powered through a MagnaTek GPD333 control and I would like to be able to control speed and CW CCW rotation of my spindle through Mach. I'm including a photo of the motor control if that helps. Is there anyone that can help me with this?

Thanks for the support!

Ok, I'm close to making chips I can almost taste it! Thanks to all of the help that I've been receiving I'm almost there.
