Seeing error in G93 code

[cncdrive]

The canned cycles are in the same modal as the G1,G2,G3 and this is where the problem comes from, that G80 is also in that modal and we did not think about making an exception of the G93 feedrate rule for the G80, but I will make that exception now.

As a work around you woul dnot normally use teh G93 in teh safety block you would use G94 and in this case you need to put teh G94 before teh G80.

G94 G80

Then simply call teh G93 before teh G93 code starts. That way you still get to use teh G80 in teh safety block just in case it is needed.

Just a thought , (;-) TP

Just ditching G80 may not suit everyone but will be fine for me till it is fixed.

Never used a canned cycle.

Using G93 code today and for the first time trying to use feedrate override.

Slowing down looked to have no effect. Got down to 30% and motion stopped and would not restart.

Fortunately it did not crash and did not lose position, Was able to rewind code and start again. Did not ruin material.

What should I expect to see? Does feedrate override work with G93?

Am I trying to do something that it is not designed to do?

[cncdrive]

I will check it, I think it should work.
Meanwhile can you please post the g-code file with which you can reproduce this issue? And also tell me at around what part of the g-code do we have to change the FRO? (If it counts at all)

[cncdrive]

OK, I have checked with random code and could not reproduce it, the FRO works fine here with G93.
So, please upload your g-code file and also your profile file.

Here is some code and my profile.

I can't get this to occur in a consistent manner.

While running the code and going up or down via the feedrate plus and minus buttons, motion will stop.

Must press Cycle Stop and Cycle Start to restart it.

Feedrate override is working, in that it does speed up or slow down motion. Unlike what I suggested above.

Not sure if it is pressing Plus/Minus at a particular point in the code. I don't think so.

Maybe pressing Plus/Minus in too quick a succession.

Don't see this as a major issue. Probably just user error.
