Homing painfully slow

1

I had not homed my machine in a while and figured time for a calibration. I initialized the homing function and knew immediately something had changed. From start to finish I bet it was 40 minutes to home this thing. Not sure what happened somewhere but I recall the last time I homed the machine it look no longer than 3 minutes. Anybody else have this happen? It crawls at a painfully slow rate.

Thanks!

The rates that the machine will travel during a homing cycle are controlled by the grbl parameters. If you have upgraded your firmware, you might need to adjust the grbl parameters.

I don’t believe I’ve changed anything. What line in machine inspector controls the homing speed?

It’s not in machine inspector, however the machine inspector can access the settings in grbl. I believe it is in the advanced section.

These are the grbl parameters that affect homing speed:

$22=1 (homing cycle, bool)
$23=3 (homing dir invert mask:00000011)
$24=25.000 (homing feed, mm/min)
$25=750.000 (homing seek, mm/min)
$26=250 (homing debounce, msec)
$27=1.000 (homing pull-off, mm)

Thanks, Larry. I will give this a shot to see what I come up with.
