Title: G1 on every line causing choppiness
Post by: kree8tiv on November 03, 2006, 12:49:47 PM

Hi,

I am experiencing a weird situation where our machine gets choppy if there are G1 codes on every line of a 3D file.  If the codes are removed the machine is much smoother.  Any suggestions on ways to overcome this in Mach?  We use a number of CAD/CAM packages, and some have posts that are not easy to modify.

If you are talking about thousands of very short moves, try reducing the feed rate by 50 per cent.

You may be only cutting at the acceleration speed not the feed rate specified in the program on most of the cuts.
