Octoprint not sending G2/G3

Get Help
1

Hi,

I'm using Gcode that has G2/G3 (arcs) in it, but Octoprint seems not to send them.

If I send them via Terminal it works an Marlin interprets it right, If they are in he gcode they are just ignored.

Marlin 2.0.x
OctoPrint 1.3.1 rc3
tevo tarantula (mks 1.3 board)

example:

M107 S0

You believe that G2 is being blocked by OctoPrint but I'm seeing a G21 command being ignored by your firmware.

But yes, the G3 commands appear to be ignored by OctoPrint.

I think the first thing to check would be both the printer profile settings for both OctoPrint and your slicer. For OctoPrint, check the flavor of firmware.

Also test if the issue persist in safe mode.

you are right - issue is gone in safe mode! So seems a plugin is filtering it out?

5

the plugin exclude region caused the problem! good idea to try without plugins.

And now you know why there is a safe mode :wink:

So... if you had asked the Exclude Region plugin to not include that area, then this would be user error, methinks.

If you hadn't asked Exclude Region to do anything then please follow-up with the plugin author on his/her repository's Issue page. Thanks.
