Two different programs.  The first program that came with the router was Liberty CNC.

Has anyone experienced issues with having two CNC control programs on the same machine?  We are thinking that the drivers from each program are not getting along and causing noise which is making the steppers wiggle and move but no movement is seen on the DROs.

General Mach Discussion / XP User Profiles and Driver Loading???

« on: November 05, 2009, 09:04:03 PM »

If you have multiple profiles or users setup on XP but a mach 3 is only installed in one profile will XP still load the mach 3 driver when the computer is turned on and a different profile is selected that does not have access to Mach 3?

I feel I might have issues with another CNC program driver (Liberty CNC) and it is causing noise that is making the table jiggle. 

I am wondering if it would solve the issue to install Mach in another profile and keep them separate.

Anyone?

I am not 100% sure but I think it just uses the printer port.  I didn't know there was a PCI card for CNC ops but that makes sense.

Liberty has been installed since day one on this dedicated machine.  I did system restore to a point the day before the installation of Mach.

Any ideas?

General Mach Discussion / Jittering Motors when converting from Liberty CNC to Mach3 - Help

I am new to this so my terminology might be off so bear with me...

This morning I installed Mach3 on a router setup to replace the Liberty CNC software that we are currently using.  I was able to get the motors moving and tuned as best as I can tell from moving the steps per rev number from the old software to the Mach.  Every thing seemed ok but after maybe 3 or 4 startups of Mach3 the x and y axis would start to "jitter" their way back to home without being told to as if there was some "noise" being picked up.  I checked the driver test file as instructed in the online video and it said there was an "excellent" response and the graph of interrupts looked like the one in the video.  So I closed Mach and opened up Liberty CNC and as soon as the program opened the same thing happened.  I restarted a few times and the problem remained when starting both programs.  I then uninstalled Mach and the problem still remained.  So I then restored XP to yesterday and that stopped the jittering motor that would walk on their own. 

Does anyone have any ideas?  Should I have tried special driver.bat?  Please advise.
