@dc42 Thanks! I'll send an email for a refurbished unit. My friend looked at the chip he would need to reflow and said he wasn't confident he could do it.

@Phaedrux I do eventually want to use the duet in conjunction with a raspberry pi, but they are hard to find right now and if you can find them they are ridiculously overpriced.

This can be marked as solved at this point, thanks for the help everyone!

Everything seems to be working as usual now with the 0.4mm nozzle. Could I just ratchet up the nozzle temp to like 270 to print with the 0.8 and 1.0mm nozzles?

I think I figured out what is going on, I slowed the print down to 10mm/s and set the nozzle to 255 and now it is printing the brim! I'm thinking the only reason it extruded on just the inside is the frequent retractions gave the filament enough time to heat. It would appear I drastically underestimated how much extra temperature you need for 0.8 and 1.0mm nozzles. I just swapped to a 0.4mm nozzle because even the brim it printed with the big nozzle was pretty ugly. Right now I'm going to try 30mm/s with a 0.4mm nozzle and the temp at 245C.

I just tried downloading a fresh benchy STL and sliced in Cura and it still only prints a sliver of the brim.

Try prusa slicer as a sanity check?

How fast are you extruding into free air when you're testing? Are you actually matching the feed rates that would be used during the print?

Same behavior with prusa slicer, I'm Extruding at 2mm/s in DWC however it doesn't have a problem extruding anything but walls, brim or skirt.

@Phaedrux Yeah I'll try that next

TPU is hard to print with to begin with. Testing with PLA would be my next step.

When was the last time prints were working correctly?

I doubt it's a firmware issue, but it could be related to your configuration. 16x microstepping is the norm. If your steps per mm are way out of whack for 1x microstepping no wonder things aren't extruding well.

The sliced gcode file you shared shows nothing out of the ordinary when previewed in prusa slicer gcode viewer.

-I'll have to wait to get some more PLA but I don't think it's a material or bed adhesion issue

-The last time prints were working correctly was before moving my printer, I had to move the printer and make a new SD card with the firmware because the old one got broken in the move. These are my first prints on the new SD card.

-I have changed the settings to 16x micro-stepping and 564 steps per mm which came from the bondtech website

@tas I just tried your exact settings but it still won't extrude along walls, brims, or skirts. As for the current I just went off of the datasheet for the stepper which is rated at 1 amp. I didn't consider that the stepper datasheet could be peak current and the config is in RMS so that would be a max in the config of 707ma so I turned it down to 700, but still having issue.

Can anyone see if the G-code I posted extruder should be extruding while tracing the wall?

@Phaedrux said in Printer won't extrude walls of prints.:

Why 1x micro stepping?

I just tried 16x microstepping and there was no change, I also tried 32X microstepping with 1124 steps per mm and still no change.

@Phaedrux I think that may have been the default when I used the firmware configurator but I can't remember.

I tried printing the same part with a 8mm Brim and the printer doesn't extrude when going around the rim except for a small section of the brim. The small bit that does extrude always occurs at the same spot in the brim.

I really think this is a slicer or firmware issue, but I don't have any PLA to try right now. I could try with CF Nylon but I have never printed with that so it may just be adding another variable.

If anyone else is running the LGX lite V2 and has firmware settings that work for them please share them with me.
