That ended up not working. I am assuming a faulty raspberry pi. I am running in standalone mode now until the 8gb Pi 4's are back in stock.

Unfortunately I lost connection, so I could not get another M122 command

@phaedrux I believe so. I'll run another test when I get home in a few hours and redo M122

While I'm here, another issue is that only my fan2 and fan3 start a full burst when the board powers on, but after a few seconds they turn off again. Does this have to do with them being Noctua PWM fans and inverted?

I built a Hevort corexy style printer with a Duet3 and RPi4.

So far, configuration has all gone smoothly, but once I started actually printing, I ran into issues.

I've looked through old posts, but cannot find a solution that works.

My printer will print the first layer just fine, but at random points during the second layer, it just stops and disconnects. Occassionally the progress bar goes straight to 100%. Other times, DWC will not reconnect at all and I need to do a hard reset on the printer.

Here is M122:

I am on DWC 3.3 and the RPi firmware is on the latest stable build. I tried a solution I saw in another post where the 5v supply is switched to come from the SBC, but that had no effect on the outcome whatsoever.

Other than when printing, I rarely lose connection. When my duet2 machine loses connection, it just keeps printing, so I'm not too sure what the difference is.

M92 E2792; I moved it back to where the others were. Interestingly I changed the M203 E400 to E2400 and the problem came back. So now I am back at M203 E400. I am a little unsure if this corresponds to mm/min of filament or extruded flow, though I lean towards filament. I am using a volcano hotend and 0.7mm line width at 0.3mm layer height, giving a volumetric flow of 12.6mm^3 /s at 60mm/s print speed. That volumetric flow is equivalent to 5.24mm/s of 1.75mm filament into the hot end.

So for every 1mm of 1.75mm filament driven, you can get 11.45mm of 0.7mm*0.3mm extrusion.

So 400mm/min at the extruder equals 76.33 mm/s print speed at those specified layer heights and line widths.

Cool. I'm still a bit confused as to why this caused a failure mid-print though. Any ideas?

I'll be damned. Your code fixed the issue. Thanks so much!

Doesn't that M203 E400 result in your max print speed being ~7mm/s?

version 1.1

This is annoying because I just submitted a huge post and it looks like it never actually submitted, so I'll be brief this time.

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.0 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-05-15b1

Rostock max style Delta printer with Zesty Nimble remote direct drive.

Config.g had Nimble's recommended extruder settings. Printer was working just fine until 6 hours into a 12 hour print it sounded like the extruder motor was skipping. No longer extruding filament. No blockages in hotend. Easily able to extrude filament by hand directly into hotend and when turning the Nimble flex cable. I removed the stepper for some diagnostic testing.

Long story short, motors configured as extruders in my config file behave like this, but those same motors work normally when configured as one of the Delta effector drives with the M584 command. I've swapped them all over the place (with the Duet powered off) and the config label of the motor is the only consistent factor. Extruder motor is locked up when the Duet is on and commands to extrude just result in loud whining and no motion. I cant fathom why this would have suddenly happened and only when a motor is labeled as an extruder in the config.g

Can anyone help?
