General Mach Discussion / System gets "Jerky" after it has been running for a while

« on: March 28, 2006, 02:42:36 PM »

Hello everybody, I am relatively new with the Mach 3 stuff but I have been very pleased with it so far. Recently we have been really using our machine a lot and we have noticed something strange. After running several programs in a row the system starts to pause between moves, instead of the nice smooth flowing motion we have come to expect it is behaving more like our old AH-HA system. I was wondering if anyone else had encountered this or if anyone had any suggestions as to what might be causing it?

Thanks In Advance

General Mach Discussion / MACH3 & Arcs in XZ Plane HELP! Its going in circles!

« on: February 20, 2006, 03:06:15 PM »

I am pretty new to the Mach 3 so forgive me if I ask silly questions. Recently I outputted a file from my mastercam and I missed seeing that I had the filters generating arcs in all the planes. When Looked at from the top the toolpath looks ok, however after crashing while running the toolpath a few times I discovered that when viewed from the front the toolpath has all these lovely cricles in it... which it endevours to follow dilligently. So, I have a couple of questions... 1> How can I tell if its the POST telling my Mach 3 something silly? (i.e. what should I look for in the G-Code which would properly define a small arc in the XZ plane where it is only travelling a portion of the arc instead of the entire arc as it does now?)  or 2> is it some blatantly obvious setting I have missed in my Mach 3?

General Mach Discussion / Homing

« on: January 23, 2006, 09:46:22 PM »

!! Warning !! ===>NEWBIE
My Home uses the X-- and Y-- and Z++ Limits for Home as well
It Seems that my system loses the Home NEG Option under the homing option or I just cant seem to get it to stick Either way it seems that sometimes When I hit HOME things move in the right direction and other times I hit HOME and it Moves X & Y in the positive direction which is NOT the right way.
Anyone have any hint as to what I might be doing wrong?
