Klipper: Unknown command G3 & G17

[djeZo888]

I have used OrcaSlicer to slice some print model for custom Klipper modded printer. The print came out just fine, but I was getting bunch of:

... Unknown command:"G3" Unknown command:"G17" ...

Is this a problem, a setting I should enable/disable when slicing? Thanks

Have you the latest version and enable Arc support?

[djeZo888]

Arc fitting is disabled - that is default Klipper profile in OrcaSlicer.

Oh, I just found this comment on reddit:

Regarding the G3/G17 gcode, there are two solutions: 1. Enable gcode_arcs in klipper config. 2. Change Z Hop type to normal (spiral uses G3 I believe).

And one of the big reasons for using OrcaSlicer is Spiral Z Hop - I have it enabled. So I have to make sure that my klipper supports these commands.

I'm having this same issue after just switching to Orca Slicer and realized even with Z Hop set to Normal it uses arcs when I have arc fitting disabled. I considered just enabling arc support in Klipper, but then realized it's just Orca still doing arc based Z Hop when set to Normal.

I don't want Z Hop anyway so I just set the distance to zero and it stopped generating g-code for hops.

Issue persists. Should be reopened.

Looked up klipper gcodes: here you are...

[gcode_arcs] The following standard G-Code commands are available if a gcode_arcs config section is enabled:

Arc Move Clockwise (G2), Arc Move Counter-clockwise (G3): G2|G3 [X] [Y] [Z] [E] [F] I J|I K|J K Arc Plane Select: G17 (XY plane), G18 (XZ plane), G19 (YZ plane)

Provavelmente já encontraram a solução, mas resolvi informar que estava tendo o mesmo erro aqui... Lembrei que foi depois de ajustar no orca, em retração, deixei em auto e provavelmente estava fazendo movimentos arc.
