• Troubleshooting machine if things go wrong

examples:

1. • Problem: Seeing random layer lines on part
   • Cause: Loose Belts
   • Solution: Tighten belts till pricking them gives them a slight twang.

2. Problem: Stepper motor suddenly very noisy or skipping steps

   • Cause: Loose cable ends in JST connectors going to stepper driver ports on controller board
   • Solution: Make sure all four wires from stepper motor are properly inserted into the JST connectors

3. Problem: First layer not sticking to bed

   • Cause 1 : Dirty bed (grease, fingerprints, dust etc.)

   • Solution: Clean bed with isopropyl alcohol and dry

   • Cause 2: Z-Offset not set right i.e. Zero Nozzle position too far away from bed i.e. at the Z=0 position there is a gap between nozzle and bed.
