I hate this board....... surely somone else has had similar problems with it

so far:

-mosfets cannot provide enough power to extruder or bed
-temperature control has seemingly perminantly stopped working don't know
why (the ADC channels died) (cannot possibly be a short, i didn't have a
thermistor in there when it happened)

-now my z axis stops working mid print until i pull the power and usb plug
out and reset everything.....

I have the usb cable with the ferrite core on it the cable is shielded and
doesn't go anywhere near any power wiring or stepper motors, i have the
limit switches disabled, i can't work this out

the only thing i can think of is the pololu is on the way out... great that
would be number 4 now

has anyone got an arduino uno that lives near toowoomba or warwick that
will part with it for cash,beer?
