Hi there

So I'm trying to get my printer to work. BUT it's still not working and the problem is that the extruder motor ticks when trying to get filament out.

I've already tried:
  • Twisting the current on the stepper motor
  • Checking the stepper motor/jumpers
  • Cleaned the whole extruder pipe and given a new nozzle
  • Tried the tension screw
  • Calibrated the extruder
Still nothing helps.... I'm getting sick of this, how the heck is this going to work???

Please tell me what your mainboard type is, how do you connect the extruder motor?

I've got the ramps 1.4 and just the cable connected to E0 with the 3 jumpers onder the stepper motor

What is the distance between the nozzle and hotbed?

I levelled the bed with a paper that can fit between. Also removed the springs because of the always levelling the bed again was annoying so fixed the bed in place

After you move Z axis upwards, is the extruder motor working while the temerature is more than 175 degrees?

It always starts ticking, when I push it trough manually it will work for 50mm and if it stops and try again, it will tick again, tries the temp till 210 fo pla to be sure

Please swap the extruder motor driver with x, or y or z motor driver, check if still happens the same thing.
