OD Arc Wizard
« on: May 25, 2008, 08:23:38 PM »
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, 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
