Hi WIlliam,
Reach out to official tech support at support@onefinitycnc.com and they’ll get you fixed up!
“Axis Motor Error Detected” is not a ‘known issue/bug’, it’s closed loop steppers doing what they do, stop and error when feedback to the controller isn’t what it expected.
Send in that email and they’ll help figure out why it is for you.
Also, new firmware, 1.4.9 is out! Try updating to that first and see if that fixes your issues!
