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.
- The Kapton tape on the bed may be uneven or contain air-bubbles - make sure it's perfectly flat, it's important and makes a big difference.
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).
How to get help
