You have to jumper the Mesa 7i33 for differential inputs, and I think it has

To Anyone that Can Help Me,
A built a 30m x 6m x 3.8m CNC machine.
Due to the size of the machine, it is a bit flexible.
I was using a Brazilian Controller for the 3 axis.
Machine was upgraded to 5 axis and I am trying to use LinuxCNC with Montec
boards.
The previous controller has 2 types of

I am using 2.2.5. I looked at the link thanks. It looks like they ended
up with the same results I am seeing. When axis opens, the PYVCP
position is set to zero but the axis position is remembered causing a
difference. And tool offsets will probably cause the same problem.

Hi all,
I have a strange problem which looks like it is related to the position
feedback, but I also suspect I may be looking in entirely the wrong place. I
have a three axis configuration where the Z axis is mapped to a PWM for a
laser. The hardware is the Mesa m5i20 controller with the hostmot2
I'm not sure if theres a reason you used Z to power the laser, but have you
considered wiring the laser to a spindle speed output? then you wouldnt
have to be programming moves in Z in order to power the laser (at least
thats how it seems it works to me?) then you just connect the spindle speed

Jim,
I have done that too, but the problem with using the spindle is that the
system stutters when the spindle speed changes. Using Z allows smoothly
changing laser power on the fly. I make Z values very small, then use large
multipliers on the PWM scale so that laser power can change quickly
Jim,
That is exactly what I am doing. There is no PID, axis.2.motor-pos-cmd is
connected directly to axis.2.motor-pos-fb, as follows:
net Zpos-cmd axis.2.motor-pos-cmd = axis.2.motor-pos-fb

There was some discussion a year or so ago about high speed I/O, which I
would still like to do for laser writing and 3D engraving. That would
require updating a PWM output as fast as every 200 microseconds (5Khz) or
gating an output perhaps as fast as 50 microseconds.

A question on that, how would the scale value enter into that calculation? I
have motor-pos-cmd directly connected with motor-pos-fb, as below. Zpos-cmd
