2 weird issues?
« on: August 29, 2009, 06:37:41 PM »
hey all!

i JUST got my cnc working again after 4 months of electrical nightmares :)

it is a x3 with keling psu/steppers, gecko 203v and a candcnc bob. Im using dolphin partmaster pro and mach 3, both i have purchased.

Today was the first day that i was able to cook up some g-code via dolphin and run it on some plastic! however i got 2 weird issues.

It was facemilling, and mid face milling the z axis hopped up from -.125" to 1.95"  (?) when in the code there was NO z axis instructions.

Then, when i want it to cut a circle around the part im making it won't and i just get a "zero radius arcline 38" in the status bar.

Im a newb and can't figure either one out. I have a video to show what i mean but its taking forever to upload.

Thanks so much in advance!

Did the Z DRO show this movement?

Sounds like line 38 of your code is a G3 or G4 move but it is not going any place, so its bad code but if you attach the code I am sure someone will tell you for sure.

Line 43 onwards  is what Mach is complaining about, there are  no values for the I J. Looks like theres a problem with your CAM, might just be a setting but I have never used Dolphin so cant say :(
