I just happen to be doing some service work in Scanton PA. I would have loved to drive down to the expo. But I'm a week too early and go back to Wisconsin friday.  :(

I got it working. It seems my A moves were absolute. I had to unselect Rot on 360. Now my code runs SMOOOOOOOTH. But now my A axis DRO doesn't show degrees.

I did your test and did not get an overspeed. I attached my XML file and a test file that has the overspeed problem. Watch the feedrate DRO when the code gets to line N400. It jumps from 20000 to about 25000.

Use the second file I posted (rotational test.nc)

Yes, A only moves. The rotational feedrate goes to high and stalls my motors.

Brian,

Here is an example of the code giving me trouble.

Mach Version 2.0.031.

I enter .0001 in the rotational diamenter DRO and the rotational feedrate is good untill a line code has no Z move.

If I enter a Diameter of 1.25 in the DRO the feedrate ramps up about every 20th line.

General Mach Discussion / Rotational feedrate problem
« on: January 07, 2007, 09:55:24 PM »
I'm having a problem with with my feedrate on my rotational axis. I have .0001 in the rotational Dia DRO. The feed rate seems ok untill a line of Gcode has no Z move. Then the feedrate goes too high and my motors stall. If I enter the actual diameter of the piece in the DRO the feedrate stays constant for a while then ramps up periodicaly. What am I doing wrong here?
