So I have checked and we are running with CV and the voltage is fine.  I am discussing getting Mach 3 downloaded right now. I am going to go tighten everything up and got rid of alot of programs on the computer. Gonna go see what happens. I guess it's backlash or noise, maybe I am looking at it wrong. I will go play.
ttys, thanks

ok I am attaching just a sample of what we are making mostly.  I do cut other pieces but this is the one giving me the most grief and is the most important.  I am going to try some of these things right now. Thanks for the help I will let you know if it works or doesn't work.

It is a plasma cutter with which we cut all 4x8 sheets of parts with, with stepper motors, we bought it from precision cutting systems, we use corel draw right now, which eventually would like to change but is not available to me right now.  I have had someone check the drawings at precision cutting syst. also.  Seemed to work there.  
There is no reason we are not using Mach 3, was told to wait till kinks were worked out, is it available now, I just asked and was told a bit longer still.
I have a sepereate computer just for that machine and don't use any other programs on it. I will check and make sure there is nothing on it that has been used.  
Thanks for the prompt response.

In response to other post, we do not use ballscrews, I have checked every screw I can see and I have cleaned the rails and greasers, and everything else I could think of.

General Mach Discussion / inconsistent cuts

« on: December 11, 2006, 04:22:54 PM »

Hi there, 
I have been using the Mach 2 software for just about 7 months on a plasma table.  I have been cutting the same pieces for since then, and just in the last month have noticed alot of problems.  First curves came out flat, circles were not round, straight lines cut in funny and getting alot of jagged not very smooth cuts.  I have cleaned, tuned motors, checked backlash, checked drivers, checked files and resent them, redone the installation of the software to double check things, I have callibrated and referenced the table.  So here I am stuck on what to check next.  What am I missing or doing wrong? What should I recheck?
If anyone can help it would be much appreciated, I've been down for a week now!
I have also noticed that I have to re-tighten the head of the torch all the time.  Shouldn't it stay snug, I have put some locktight but still comes loose after awhile.
I was just starting to enjoy this machine and was getting the hang of it till now, I am out of idea
Hope to hear soon
A
