A head scratcher for me

Hi Andy
The right wing has the big end at XY but the left at UV. The UV iside started ok then went really fast. I tried it on Mach 3 and it worked perfectly, I used Profili2 Pro to generate the code which is quite old now. I contacted Stefano at devcad.com asking if it supported G93 and it doesn't but his new software DevWing Foam does.
I think I can get around it by generating the gcode for right wing inverted which the software will allow and the left normal , but I'm not 100% certain if I'll end up with a wonky wing , need to try that,.
I prefer to use LinuxCNC because AXIS shows the profiles correcly, Mach3 doesn't do that.
Thanks
Keith

Are you in a position to test an air cut?

It is possible (but not likely) that setting the machine to the UV plane will solve the problem in cases where the UV side is the big one.

Hi Andy
Thanks for that, sounds like that may be the answer, I give it a try and let you know.

Well, it feels like it should be but a cursory search in github didn't show the selected plane as being used in the velocity calcs.

Hi Andy
Changing the XY to UV plane made no difference still went fast on the UV axis. Damn.

Pity, though it was more a hope than an expectation that changing plane would help.

What does the first few lines of your G-code look like?
