General Mach Discussion / Mach3 aggressive motor movement stalling the motor
« on: May 22, 2019, 03:02:05 PM »
I an issue where the Z axis motor stalls in various situations. It looks like that in some situations Mach3 is not using the acceleration values what I have configured for the Z axis. You can see this in the video here: https://youtu.be/j8rkjhrz3Ck
In the beginning there is an aggressive movement which stalls the motor if I try to run the program in faster feedrate, then after few seconds you see that the motor is accelerating nicely. Why there is a change in the acceleration even the G-code is in the same feed rate. I use Fusion 360 for modelling and creating the G-code and Mach3 is connected to CSMIO/IP-M 4-axis controller.
Is there anything I can do about this? At the moment the CNC system is really unstable due to this and requires constant monitoring. The zeroing the Z axis again and again after every stall is frustrating...
