Easiest way will be editing HAL file which describes the stepper
output pins connection and you are done in 30 seconds ;-)

Just make the INPUT_SCALE negative in the .ini.

David,
Try reversing the sign of the INPUT_SCALE parameter in the AXIS_#
section of your .ini file. I used this to reverse the direction of my
steppers i.e.
INPUT_SCALE = 12000 0 turns clockwise
INPUT_SCALE = -12000 0 should turn anti-clockwise
Hope this helps.
Andy

I think the Hostmot2 files are on the Mesa website, but my understanding
was that they only work with the 5i22. I should look more closely at
the VHDL source I guess :)
At the moment, there is no EMC2 driver fo

Of course, it would have been better if I had put parts 1, 2, and 3 in
the correct numerical order.
Please rearrange in your head ;)

Yes, you'd need a special HAL driver that takes a velocity input to send
to the drive, and produces a position output to send back to emc.
Looking at the pdf you linked to, you would have to arrange for emc to
produce a 16-bit velocity command to be written to register 0x30

John,
I have run 3 of these on a mill without any major issues.the only
problem I have found is that some of the revixsion of the controller pcb
used opto isolators witha limiting resitor in series with led in the
opto. this tends to cut down the highest speed you can run at. my fix on
thes
Anything you can add will help others speed past this part of installing and
running
EMC.

Yes, absolutely.
In fact there are at least two ways to do it.
You can run open-loop, sending positi

Of course you can. I have a machine set-up running like this now. But as some
others have already said, the speed of software step generation will be your
limiting factor. If I had to do it over I would have taken a different route
with my set-up, and used hardware step generation (probably w
