Dear all,

Today I ran into a problem that I'm unable to solve and was hoping somebody here could help. Please see picture attached.

The mill is supposed to be at the arrow but instead decided to take the yellow path off to my limit switch...

So the G-code says X97.634 Y239.147 which is roughly the area of the arrow. In the lines before or after there is nothing suggesting otherwise.

My machine coordinates say it's at X149.6563 Y360.9625 which is also roughly at the position of the arrow.

So suddenly my X-axis has made a ghost move to wherever and hit my limit switch and is no longer registering it's position. It's done it twice at the exact same moment. So running the code a second time on exactly the same moment it's done this...

Any ideas what could have happened? Or what I should be looking for?

CNC mill: ChinaCNC 6040
Controller: MKS-V-V04.PCB (as supplied)
Software: Mach3
Modelling software: Fusion360


This hasn't happened before. It happening at the same time in the same program baffles me.


Thanks.
