That would be 90 degrees phase-shift I think, so not quite right.
siggen might be the way to go. I think there are bridge

Does anyone know the tpi or tpmm of those miniature zerks on Chinese ball
nuts is? Its 5.75mm for the major thread diameter, so I assume they might
be able to call it a 6mm thread, but it is obviously a coarser tpmm than
the 6x1mm's bolts I have.
I am considering making an adapter

I retrofit an induction heat treat machines that operates in exactly the
same manner. The machine I worked on was made by
Inductoheat.
I replaced the motion controller with a PC running Mach3 ( this was
years ago.. before I saw the light.. ;-) )
I tied into the existing heater controls.

Hello Sebastian.
I missed that. That would easier to do, since I can modify the step lenght
to use the duty cycle I want.
Controlling the velocity to vary the frequency, that seems pretty doable
for me. The frequencies that I need to handle are from 10 Khz to 50 Khz, so
that would no be a problem

Some ports require external pullups. Is your port connected a pcb? If
so try and solder a pullup on that line if you dont have one.

I mistyped, actually I am using G53 to move on machines home position.

I used oscilloscope. I am using the base thread period to execute data/address
read/write periodically and I can easily measure/detect the data_strobe signal
(pin 14) during data read/write. But if measure the address strobe signal (pin
17), nothing happens.
F
How do you measure the strobe signal? You do realize that it is very
quick and only happens during data transfer. I.E. Once on every read and
very write.

Tuning up this lathe with its new z screw, one of the things I miss in this
new uber-busy DRO display that is sharing the backplot window almost to the
point of distraction, is the combined velocity display it used to have.
Reading the wiki, I see a mention of .axisrc, but it doesn't

I have added just two simple buttons (pyVCP), one for "go to home" and other
"go to machine home" but after executing one or another, when machine reaches
its position, it switches Manual control[F3] to Joint mode, so it is not
possible straight away to jog with arrow keys on keyboard... I wou
