General Mach Discussion / Mach3 - MPG - Precise control as it is on an industrial CNC...
« on: June 14, 2019, 05:24:43 PM »
Good afternoon all,
I posted this on the Zone the other day and didn't get any suggestions so I thought I would try here. I know Mach 3 is somewhat "extinct" but thought maybe someone could chime in. Even if the solution lies within MACH 4, I would like to hear about it.
I have MACH 3, been using it for a decade or so. My current setup is: Windows 10, Mach 3, ESS (Ethernet Smooth Stepper). For the MPG, I am using a FANUC MPG wired up using "A" and "B" etc.
Regardless of what computer, what MPG, what machine, what configuration, I have NEVER been able to get the MPG to behave as it does on any industrial control.
I can set the distance per step, and if I slowly rotate the MPG, I will get a near perfect step with every click of the MPG. However, if I rotate the MPG any faster than "SLOW", not all clicks translate into an increment of motion. On industrial CNCs the machine will move 1 increment / click of the MPG.
I know there are settings for velocity mode, multi-step, single step, etc. I believe I have tried every combination of these and I cannot get the machine to perform "correctly". The best is in Velocity mode and the machine will move some distance greater than a single increment, however, it still starts and stops crudely.
I have tried the tuning function as well with no luck.
Has anyone found the magic combination to getting industrial MPG performance on MACH 3?
Thanks in advance!
