The part looked right but the caliper says every dimension cut a little small.
What is the range of deviances? What I mean, how consistent is the
deviance in dimensions? Is it very close in all directions, is the
error along one of the joints or is it
Martin;
For what it's worth - I'm playing with a new machine of mine (Sieg KX1 with
Gecko G540) and am looking at the backlash in the x-y table.
To do this, I put a dial indicator on an axis;
move +1mm, +1mm, +1mm, all show accurate moves;
move +1mm +1mm -1mm shows the backlash.
What if you
One recommendation is to put a Vee cutter in your spindle and run a program
where the Vee bit just touches the material in a uniform grid pattern. Take
your part and measure all the positions from the 0,0. You may have your
machine set up in such a manner that it is not just perfect. When I did
Hi Marty,
As other people pointed out, it might be better not to jump to conclusions the
cause of the error may not be stepper calibration.
How long have you been using CamBam and what do you think of it?

Hi EMC users,
I have EMC running on an old pc, latency number about 25000. I got an
occasional real time error with latency number set at 22000.
I drew a part in CamBam, generated some g-code and cut a part. The part
looked right but the caliper says every dimension

A circle pocket drawn 1.50 diameter cut about 1.42 in diameter,

Just a thought, do you have metric leadscrews calibrated in TPI?

Nope. They are 20 tpi.
