Mark2 3D Printer


Common Mistakes

None yet. What did you break?

Z Axis Binding / Vibrating

  • X Axis spaced wrongly
    • Loosen screws on back of x-idler, adjust spacing, tighten, try again
  • Z stepper driver current too low
    • Increase current to Z motors. Turn Z stepper driver trimpot 1/4 turn, try again.

Axis Reversed

Most likely motor is connected the wrong way around. Turn off / disconnect power, disconnect the motor from RAMPS and plug it in the other way.

HotEnd Can't Maintain Temperature

Check that the duct on the print fan isn't pointing directly at the HotEnd - it has a bit of wiggle room for adjustment, and should be angled downwards, towards the print. Additionally, you may want to try running the fan a little bit slower - they're pretty powerful fans, and even at < 50% they should be more than capable of keeping the print cool - check your slicing settings.

Print Problems

Print not sticking to bed

The nozzle is too high (probably). The first layer of the print should be smushed against the bed, significantly flattened by the HotEnd nozzle. Adjust your Z offset to achieve the correct first-layer height.

Print corners are lifting

The nozzle is too high (possibly). Double check bed temperature against the Printing guide.

Overhangs are messy

Cooling fan may not be set high enough in your slicing settings, or the fan-duct may not be pointing at the print (it has a bit of room for adjustment).
