Bondtech Extruder Occasional Clicking

Post by Northspire » Sat Apr 22, 2017 10:56 am

ok I have finally got the printer up and running. The only lingering problem i Just can't seem to get ironed out is the extruder clicking every now and then. I included a copy of my config file. I have a Bondtech QR extruder. I have tried adjusting the steps but it didn't seem to do anything. Any Ideas?


Configuration file for dc42 Kossel

; Communication and general
M111 S0 ; Debug off
M550 ; Machine name (can be anything you like)
M551 ; Machine password (used for FTP)

M666 X0.10 Y0.16 Z-0.26 ; put your endstop adjustments here, or use auto calibration to find them
M92 X80 Y80 Z80 ; Set axis steps/mm (20 tooth pulleys, 0.9deg/step motors)

; Z probe and compensation definition
M558 P1 X0 Y0 Z1.0 H20 F300 T12000 ; Z probe is IR and is not used for homing any axes, Z probe dive height 3mm, probing speed 300mm/min, travel speed 12000mm/min

I don't know the Bondtech extruder, but some extruders with metal gears tend to clunk when the extruder direction is reversed towards the end of a move due to pressure advance. Maybe it's caused by backlash in the gears. You could comment out the M572 command near the end of your config.g file to see whether this is what's happening.
