Hi Everyone,
I am pretty new to Maslow 4. I set it up yesterday on a homemade, somewhat collapsible frame. I say this in case it is possible that the lack of frame rigidity may have contributed to the problem. I started a long CNC session yesterday with gcode made by Cambam. The cuts began with several pocket operations followed by inner profile operations followed by outer profiles. At one point during the final outer profile operations, it stopped and I was unable to retrieve the serial code. The cuts were going at a feedrate of 30 inches per minute. Today, I tried redoing cuts that it missed. This time at 40 inches per minute feedrate. This involved pockets and outer profile cuts. It did the pockets successfully and started the profile. This is how it looked:
This time, I captured the serial data. It is as follows:

Yesterdayâs cut went for much longer before it failed. Might it have been the more aggressive feedrate? If any of you with more experience can tell me what these errors that led to the end of these jobs (and the sad waste of time and plywood), I would appreciate your guidance.
Thanks,
Paul,
