Unsolved Intermittant Extrusion Issue
-
I have an interesting bug that has come up a few times now. Randomly, my LGX extruder appears to partially lose power from the 1LC board. It gets to where it is struggling to push filament through the hotend, and it starts skipping. This normally happens at the start of a print. If I disengage the extruder gears, I can still easily push the filament through by hand, so its not a nozzle clogging issue or anything mechanical.
If I turn off the printer and then re-power it, this problem goes away completely and the extruder works normally again.

Can you share the results of M122 and M122 B# where # is the canbus address of the 1LC?
Also please share your config.g and a sample gcode file that has the issue.

How fast is the attempted extrusion when it stalls out? Is it always at the same point?

@Phaedrux said in Intermittant Extrusion Issue:
How fast is the attempted extrusion when it stalls out? Is it always at the same point?
G1 X30 Y-220 Z0.3 F750.0 E18 ; draw prime line
G1 X30 Y-219 Z0.3 F1000
G1 X0 Y-219 Z0.3 F500 E5When it happens, its always at the beginning of the print, when it goes to draw the prime line. It wont extrude. The extruder acts like it is either being under driven or a clogged nozzle, as it skips and vibrates. It barely extrudes at 1mm/sec.
I've confirmed zero clogging, and the extruder gears move freely so absolutely nothing mechanical. I've gone so far as to remove the extruder and test it.
It seems as if the extruder stepper is somehow losing current and just being under driven. As I mentioned, if I power the printer off and then back on, it works just fine again.

First I would check for a poor crimp connection or wire damage.
If the wiring all checks out, the toolboard may need to be replaced. When and where was it purchased?
-
I checked the wiring and all looks good. It seems as if it may be losing signal to one of the two coils. I have never had any issues during a print; it finishes the print every time. Only occurs intermittantly when starting a print.
Purchased form Filastruder on 25 Nov 2022 with 8 other 1LC boards and connector kits.

@Phaedrux So interesting enough today, I did one small print and was actually getting intermittent yellow error messages the whole time it was printing about Phase A and/or Phase B of '0' being disconnected. It printed fine though.
