Ulticontroller goes to "Sleep..."


Recommended Posts

Posted · Ulticontroller goes to "Sleep..."

My Ulticontroller keeps going to "Sleep..." at random intervals after beginning a print. How do I wake it up?

It stops a print ruining the process, sometimes 3 hours into a 8 hour print. I can't keep using the controller.

I'm using board v1.5.4, Win7 Cura. I'm running the GCode direct from SDcard.

    Most likely it's a MINTEMP or MAXTEMP trigger, which is not correctly reported to the display (that sucks, I know)

    It happens because of a bad connection to the temperature sensor, so you might want to double check those connections. However, it should also happen with USB printing.

    Make sure those are really tight. I'm not a huge fan of the current small screw blocks, but I don't know any better solution.
