Hello everybody,
I am looking for some option to change the phase between two pwm signals of the
same frequency generated by pwmgen, like this:

The pwm frequency is 1Hz. Is there an easy option to achieve this?Pwmgen
doesn't support this option. I checked the

this has an X component ( no distance tho )

The motion controller has no way to know where the centre of rotation is, so it

Hmm, are these angles used by Axis to display the correct geometry for the tool
tip in the backplot? If so, that doesn’t seem to be working (at least in
2.7.0~pre6). I have the Orientation and the Front/Back Angles set (angles,
perhaps incorrectly) but Axis shows the tool pointing up from

If you want to feed in a phase signal then you might need extra scaling.
I honestly know jack squat about CNC lathe tool setup but I am wondering if
this problem has something to do with wether you are working on a radius or
diameter of the part? Also you input T1 M6 G43 I know there will be no H

Marcus,
I'm just a party doing what I can to run a machine and make a part here
and there, so I can't address the larger plan you shared for bigger
projects.
I have often wished there was someone I could contact with issues I come
across and challenges pertaining to upgrades and the like.
Hi,
A unipolar motor nameplate rating will be for half coil.
If you use both coils of the phase (wired in series, with the center tap
insulated), then you want to run at about half the rated current (since
you have twice the number of wire turns). This will give lower speed
performance due
On a machine with a rotary A axis, if I run
G91 A360 X10 F100
the machine moves 100IPM on the X and the A axis completes a 360
degree rotation at the same time. If I then run
G91 A360 F100
the machines takes almost 2.5 minutes to complete the rotation, because
it is only running 100

For your check, make sure the 4th axis is set to angular as the
first thing to check in the .ini file.
