1. Speeds -Check your speeds and accels, especially travels. Limit A and B steppers to 300mm/s and 5k accels for testing. Stealthchop Disabled.
2. Belt Routing -Ensure belts are not touching plastic on the back of the A or B drives. Post a photo if unsure.
3. Grubs -Check A and B motor grub screws. Make sure they are tight and on the flats of the motor shaft.
4. Belt Tension -Make sure your belts are not too loose or too tight. 110hz on a 150mm length of belt.
5. Stepper Drivers -Ensure heatsinks are installed and you have cooling fans blowing air over the mcu.
6. Panels -Ensure rear panel has not warped inwards making contact with the belts on the back of the gantry. Check with hot chamber.
7. Stepper Motors -Set to a reasonable current. 0.8amps-1amp for most common motors.
8. Gantry Check -Disable motors, center the toolhead and push the Y axis towards the back without touching belts or toolhead. Does the X axis move?
9. Slicer- Ensure you are not over-extruding. This can cause the nozzle to snag while printing.
10. Cooling -Corners curling up can also snag the nozzle. Use Z hop if possible.
11. Linear Rails -Snagging of the carriage while moving on the rail can cause shifts. This can often be heard as loud clicking during rapid toolhead movements or can be felt during manual movements.
