Hi
Just running mach 3 on the lathe
Up graded to the latest V as I was having problems with taper threads.
The threads are now working fine, but when I use a wizard that has
any arcs(OD Arc Wizard: ie g03 or go2) the program is cuting a full
circles.
I was trying to put a radius on the end of a 0.525" shaft and
the program keeps trying to cut a full circle.
Several inserts down
any help!
take care
eddie

Hi, Eddie

Your preamble at the top of your G-code needs a G91.1 or G90.1 to set the I J's to Inc or Abs Mode depending haw the code is written.

Use the MDI line to change it, It should fix it.

In your G-code put the G9#.# on a separate line from other G9## code as below Mach doesn't like it.

G90

G91.1

Hope this Helps, Chip

Hi, Eddie, Rich

That can cause problems also.

Thanks, Chip

Hi, Rich

Hear you Loud and Clear on that, For Sure.

Been using a startup string and the Use on "All Resets Option", To level the playing field a little.

Sorta forces Me to add Preamble code in My G-code, May not the thing to do, G90 G20 G17 G40 G49 G61 G69 G50 G80 G94 G91.1 G52x0y0z0  F100
