Andy can you think of any
Andy can you think of any good ways to change acceleration on the fly?
I could call a custom m code in my post processor if I had to.
Or is it possible to increase the deceleration if under 1000rpm? Currently
my spindle acceleration is running through a limit component

I agree it would be nice to change acceleration on the fly based on the G-Code.
The AC Servo on the spindle responds really quickly so fast acceleration is
really fast. Great for the tapping. Annoying otherwise.

I thought that it was indicated by motion.motion-type, but it seems not:

Quick answer before I go out.
Peck Tapping breaks the chip otherwise they can break taps. Eg tap m6 down
30mm you might break it. But do it in two bites you should be sweet
and rpm is 400.
If I somehow work out how to know if g33.1 (rigid Tapping is active) and
export that to a python script.
Impressive. Lots of questions.
Why did you make two passes? Just because? Seems like the spirals could get
caught and muck up the threads on the second pass.
Was this steel or aluminium?
What type of coolant are you using?
Do you have an oil separator disk or belt and aeration to keep

I can turn main power off at the wall and it will re line up with tapped
threads so long as I leave it in the vice.
That's so cool. Love linuxcnc
Might try a m20 tap sometime. I have 7.5kw spindle. Be interesting to see
if it can
Reading about emergency stop relays/contactors use to have an extra
normally closed contactor. If I got right this contactor may be used to
monitor relay is not welded together and to fulfill highest requirements
they should be monitored individually since otherwise a single failure
may be
