I am running a BobsCNC Evolution 5 machine (this is the Evolution 4 with a bigger work area). This is a GRBL machine.
I am able to connect the GRBL controller to Easel and home the machine without issue. As a sanity check, I manually triggered each of the axis switches and confirmed that Easel shows the switch state changing. All that works great.
However, after homing the machine, I can only jog the machine a few steps before it becomes unresponsive. E.g. I jog X a few times, and then attempt to jog Y and the machine does not respond. At this point, the machine will not respond to any commands from Easel. The only way to get it moving again is to disconnect the USB cable from my computer and reconnect it. Of course, this isn’t much help as then I have to home the machine again and the cycle starts over. For this reason, I have been unable to attempt a cut.
Any ideas where to look to find the problem? My best guess is the controller is getting into an alarm state and becoming unresponsive for safety reasons, but I do not know how to check this hypothesis.
