can I desolder the driver and solder a new one on?

Hi

the motor was work right before hand
the motor only spin in one direction (anti-clock-ways) with both commands
try connecting a different motor, same results
motor sounds the same before problem
cheers

z motor only spin one way after one of the fan shorted out i checked y,x they seem to work ok,
any help would be nice
cheers

I guess I can after I get everything up and going

@deckingman:

Wow that's impressive. May I ask how the hot end is fixed to the carriage after it gets picked up?

magnetics, holds real well

build area is X720 Y320 Z 800
With 3 hot ends, changible tools
diamond hot end
e3d volcano
direct drive with e3d hot end
so the hot ends get pick up as need in the print then droped off

I call it "Small Box"
