Thanks for the quick reply. I will need to check again when it fails, but I am 95% it was 17 once and I think another number a different time. Once the message was for the X-Y axis and once for the Z axis.
There are no issues with the limit switches that I have seen. It always homes correctly. I checked the z-switch hole and it was clean.
Also, during the most recent print, I managed to walk by the printer before the error occurred. It seemed like something happened during the first layer causing the head to stop moving. The fans were running, but the lights on the print cores were off (not visible in picture). The motors were idle. It almost seems like the printer lost communication to the motors and extruder but thought they were still connected and continued to print.
I have updated the printer firmware to the latest version, but Cura is still on 4.4.0

I've been around on this forum quite a bit and unfortunately I don't know much about this error. It seems to be somewhat rare maybe?
Could you please say which error number it is? Is it 17? From reading this it sounds like the error only happens during homing? Anyway it suggests a few things to check. Although I'm wondering if you are getting a very similar, but different error?

Errors 16 and 33 also sound similar. I guess step 1 is to figure out which error number you are getting.
Also regarding Z errors - look in the back of the printer under the print bed (just pull the bed up). Under the bed is a long screw that sticks down. Directly below that is a hole. Clean out that hole.
