Title: Jog VS G00 Performance
Post by: sgoedvolk on June 24, 2010, 04:29:14 PM

With a jog we can easily get 50 IPM, with G00 best we can do is 17 IPM! Any suggestions what could cause this and how to fix.

Thanks!

If i recall corrrectly you are limited by the max velocity, so when jogging at 100% or G0 (a rapid move) you can go only to max velocity.
Irrelavant, you would only continuosly jog or rapid at a rate such that you are not missing steps. With steppers anyway....

There is a feedrate can be overiden from 20 to around 300% by putting a percenatge into the DRO, maybe that's what you have and didn't realize it,
but the Led will light up warning you. Same practical comment made above would still apply.

Check to make sure your rapid (G0) overide is at 100%. As you have noticed JOG and G0 are too different things in mach.
