Super Slicer and Duet2

BlueDust

I assume I will have this same problem on my Duet3 printer, but haven't yet tried it as I am only testing out Super Slicer to try and troubleshoot an Extrusion problem I am having with Cura and ideaMaker on my CoreXY (Duet2+Duex5 and Hemera). I may post this issue to see if anyone has seen it before as a seperate question.

I keep getting these ere errors on the console. I even switched the printer type from Klipper to Rep Rap and still get this error. As I am new to Super Slicer, I am not sure where this error is coming from but do see these commands in the gcode file. I have searched on this forum and was only bale to find 2 posts, and they didn't seem to answer the question of how to resolve.

Error

Error: Bad command: SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=5

; when we switch to other features, go back to 5

@bluedust I'm using Super Slicer on my Duet 3 Mini. Also setting it to Rep Rap. I searched a recent gcode and found no line like that, despite the fact I'm using it for acceleration and jerk control.

Have you check to see if this command is in your start gcode in Super Slicer?

Also, not sure if you are also using a Voron, I saw a mention of Voron in your .gcode file. I was having some overextrusion with Super Slicer and found this profile https://github.com/AndrewEllis93/Ellis-PIF-Profile

It's been giving me some really good prints, but make sure you change the build volume etc to your own because his is a Voron 2.4 350. And he's got it set up for Klipper, but I found all I had to do was change that to Rep Rap and input my own start gcode. He has a handy guide on there too https://github.com/AndrewEllis93/Print-Tuning-Guide

SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=5 is a klipper command that RepRapFirmare does not understand. The klipper devs decided it's a good idea not to use the common GCode to set jerk (shared by Marlin/RRF) for their Square Corner Velocity. In this case it's probably not for the worse, since SCV values do not map to jerk values at all.

Depending on the printer profile, these commands may be custom gcode injected per feature or via a post processing script.

I have a Rat Rig vCore Pro 1.3 and used the SS default profile for vCore v3. Rat Rig uses Klipper by default on their newer printers. But as I use Duet boards, have so far chosen not to. That would explain why Kipper is being used by default.

Saying that I already did comment out everything in Start g-code, but adding homing.

;START_PRINT EXTRUDER_TEMP={first_layer_temperature+extruder_temperature_offset} BED_TEMP=[first_layer_bed_temperature]
;enable this if you have a BTT Smart Filament Sensor
;SET_FILAMENT_SENSOR SENSOR=my_sensor ENABLE=0

Scrolling down to the next few custom g-code settings showed me that there are many many more custom g-code options that I was not aware of.
4th from the bottom is "between extrusion role change G-code" and that includes Set-Velocity commands. I bet that was it, and will comment that out as well.

; once we start printing infill, increase square corner velocity to 10
{if extrusion_role=="InternalInfill"}SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=10 {endif}
; when we switch to other features, go back to 5
{if extrusion_role!="InternalInfill"}SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=5 {endif}

Thanks for helping me find it!

Thanks for that info. Even though I am not using a Voron, it still looks like something I should review to help me get SS working/produce good prints.

@bluedust Glad to hear you found it.

The Voron and Rat Rigs are pretty similar so the settings should work pretty well!
