What is going on?
When clicking on the home button in repetier I get loud noises for a long time, and I start to smell the motor overheat!!!!!


I also get the error extruder is switched off Mintemp triggered

I have the i3 B package, but I upgraded to a GT2560 board and DRV8825 Motor drivers. I only have one extruder.

I assume the one extruder gets connected to the location of extruder 0??


Is this noise normal when I first plug in the printer.

How do you connect the motor drivers? Can you take some pictures?

The problem was solved by adjusting the vrefs on the driver.

Can you tell me which way will increase the voltage? Clockwise or counterclockwise.

I still have problems with my Z axis. The motors get really loud or hum when I adjust the vref.

Rotate anticlockwise slightly to increase voltage.
When you want to move z upwards, and motors make big sound, you should check if DRV is bad: Plug x or y DRV to z DRV slot, check if z motors still make sound.
