I have only lightly been following this thread. I have some experience
converting a large hmc and initially not knowing how to hook up the
+/-10 volt signals from the mesa hardware. Initially testing I sure
hooked it up wrong. The servos would spit and sputter when outputting a
constant volt
The only thing I would add - set G61 (exact stop mode) to be sure emc is
using the max acceleration in the ini. (Thanks ChrisR for pointing that
out).

Could you explain your system a little. When you where explaining it on

First tune the velocity loop in amp

-Adjust the loop gain of the amp to get the best waveform - (match the
square wave the best you can)

the shield hooked to ground.)

all you need is a quadature encoder + index installed on your

I would vote mechanical also - That is how are old machine does it. It
was pretty easy to setup. (I actually wrote a comp for the spindle
gearbox/index for this machine). it sets the transmission into 'lock'
mode then creeps into the dog. Checks to see that the spindle is at 0
rpm and then
retune a little after I turned up the current limit on all the
amps to maximum. :) I have the ferror set to .001 right now and did a
bit of machining with no issues.

ps - that should give us about 16000lbs peak and 8000lbs of force
continuous. :)

Now just need to come up with a bracket (and a belt guide on the encoder
pully)

well - we heated it up mainly for ease of slipping it on. it almost
went on by hand. it will probably come off pretty easy.

At some point we might actually have to *gasp* buy a pair of timing
gears. ;)

the amps that I built had a boot strap that required charging.. I also
never had issues with it not charging at startup. I figured there was
enough dithering that everything 'just worked' tm

It is actually a little easier than that. Each tool has a mechanical
barcode. So I call the tool I want - it spins the chain until it reads
the right number on the tool and puts it in the prepared location.
You can see the rings on the tool (the reader is behind it)

Are you using the 7i48 similar to how it is done with the printer port?
So emc is doing the motion and trajectory planning and the mesa card is
setting step rates and such - just using usb? Also - I think some would
be interested in the S-curve acceleration added to emc.
Nice work!

You can specify a rotation when setting the g55 to g59.3 coordinate systems.

This doesn't make sense. When I set a g10 coordinate system - it stays
until I change it. Even on restarts of emc. (as I understand it 'touch
off' works the same way - just in the background it is setting the same
way as g10.
could it be you are not homing to a known location?

to add to this - the offsets are stored in the var file. I don't think
they would get reset without the user knowing...
(my 2 cents) ;)

I think mach has a place to tell what the 'radius' is of the rotary axis
so the feed rate is calculated based on that. (but they cannot do kins
and such) Inverse time really is the only way to go - that is what the
big boys use.
