Hi All, Have a mendelmax 1.5 using sanguino 1.3a & latest Marlin firmware. Frustrated with the smart controller I bought from here. According to guys like this, it should be just as easy as uncommenting a few lines in Marlin (granted he is using RAMPS but the same principle should apply, right?) No matter what I try when this thing powers on it just shows black rectangles instead of gettiby Flightless - Sanguino(lolu)
Dust, Thanks for all of your help. I have now replaced the pololu and my printer is working again. I'll look at replacing the power mosfet in the future.by Flightless - Sanguino(lolu)
Ok, I swapped the stepper of the extruder for another one (with the board OFF this time ), and it runs fine, I have definitely killed the other one. But the heatbed issue persists...you wouldn't have any idea about that would you? (Apologies for the double-post)by Flightless - Sanguino(lolu)
Ok, then I will need a new pololu driver for the extruder. Can you explain the heatbed issue?by Flightless - Sanguino(lolu)
Hey All, I recently replaced my extruder head and it required a change in the extruder motor direction. So I swapped the wires for the stepper motor to change the polarity of a coil and now the extruder just jitters instead of working. If I plug the extruder motor into the x-axis and jog it, it runs fine. Now I know that swapping wires on the stepper motors isn't supposed to be able to damage tby Flightless - Stepper Motors, Servo Motors, DC Motors

Can I get an update on this? Did replacing FET work? I've been having the same issue - my heatbed powers on as soon as I turn on the power supply and won't respond to commands.by Flightless - Reprappers
Hey there, I've been using my MendelMax 1.5 for a few months now, and as I was finishing my first spool of ABS, I decided to change my extruder body since I had damaged it superficially upon assembly. The extruder body I had printed out was backwards (i.e. a mirror image) and so I needed to change the direction of the extruder motor. In my attempts to do this I now have an extruder motor that roby Flightless - Firmware - mainstream and related support
