Hello. New to the group. A newbie when it comes to CNC, but have played with (serious) machine tools and computers for years. I ended up buying Jamie Wilson’s R7. It has worked fine, but has some intermittent issues that I could use a little help with.
First thing I did was make sure the dust collection system was grounded, and that there is a good ground on the controller/system. Have done some long cuts and had good luck with them, but today the unit is not responding to commands without a reset. Cut two clamps out and then tried to Move Gantry (bCNC to an M1Gradus Pro-grbl1.1) and nothing happens. Changed serial cables earlier today after it did this and it worked until now. Trying to determine whether theproblem is the Raspberry Pi or the Gradus. Any thoughts on isolating this to one or the other?
Have a little more info. Could be a time out. Cut several clamps without issue, then walked away. Checking the syslog found:

Had done a previous lookup on the error usb_serial_generic_write_bulk_callback - urb stopped: -32
and found this thread.
tried the “dwc_otg.speed=1” and found it did not help.
Looks like it is a heat issue. The fan placement in the control box could be better. Working on a new mount after testing a new location. In the original location, fault LEDs came up after just a minute or so. In the new location (handheld), no issues after several minutes.
@Steve_Epstein it could be heat. One way to know for sure is once you have an error check the stepper sticks. If there are red lights on the sticks it has moved into thermal protection.
