Crazy moves

jarjar

Hello,

On my delta, with a 300mm round bed, I'm trying to print a priming line before starting the actual print with the following gcode:

G90 ; absolute positioning
G0 X-49 Y-139 Z0.2 F12000
; Arc Prime Line
G3 X10 Y-147 I49 J139 E9 F1000
G3 X49 Y-139 I-10 J147 E12.5 F1000

When I input this gcode manually in the web console, it works fine.
When trying to print a file, the first G3 move makes the printer go up diagonally?!

For reference, this is the whole gcode header in the test print file:

Which firmware version are you using? There were some fixes to G2 and G3 moves recently.

I'm using 1.19.2.
I didn't bother upgrading since I did not see any bug fixes related to G3 moves in the recent releases.

I updated to 1.21, and saw a message that the G3 was outside limits.
After updating the printable radius all is good. Sorry for the noise.
