Machine: CR-10S PRO with TM3D marlin firmware
Problem: nozzle moves downward mid-print, damaging the print and machine
- Printing a model of height of around 250mm throught octoprint.
- At around Z-height of 6mm-12mm, nozzle move downward, destroying the print. Printer is then turned off to prevent damage.
- Printed the same model for 3 times on Octoprint, the z-height (6-12mm) and location of the occurance seems random. Printed the same gcode on sd card and it was fine.
- Printed another model with Octoprint and it happened again. Printing the same gcode on sd card and it is fine.
What have been tried to solve it:
I don't think the downward movement is homing action, as the printer homes by homing X, then Y, then Z; while what was observed is that the nozzle was moving sideway and downwards.
Slice the model again.
Print a different model.
Print the same gcode on sd card and it was fine.
