I don’t know what is happening. It was working just fine and then the Target Buffer Size Not Found appeared and it went to homing.

Waiting for connection…

Your message says target buffer size found, not ‘not found’.

Connection Lost is the important one here. The Ortur (or Windows) disconnected the USB, and then reconnected it. Check to make sure your USB cable connection is secure. If it’s loose, this can happen easily.

Okay, with that do you have any suggestions?
