CPU Speed A Factor???

Greetings,

Running LinuxCNC 2.5.4 with a 1GHz processor chip.

Created a program cutting a surface that output LOTS of point-to-point data.

Programmed feedrate was 10 inch-per-minute.

Watching the Velocity on Axis, the feed never got much over 2.5 inch-per-minute.

Is it possible the CPU was not able to process the data fast enough?

Cheers,

Dave

Its more likely that your speed is limited by the trajectory planner and blending

For profiles made of many small segments, you should try adjusting the blending
with G64 Px.xxx

Also LinuxCNC version 2.7 has a new trajectory planner that deals with profiles made with many
small segments better than the old planner, so it may be time to upgrade...

Greetings,

Ahh, G64!!! Time to dig out the manual and do some reading.

Many thanks,

Dave

Greetings,

The mill is 12x40 inch.

X Y and Z are driven by NEMA42 motors rated at 12N.m

Is there something within LinuxCNC to indicate the acceleration values?

Cheers,

Dave
