Did search, did not find...
Is anyone running the R990h boards? I can't find the step time/space and
direction values, so if someone have a guess or the real numbers I would be
very thankful.
It feels like I've been terrorising the list lately, but one problem never
comes alone...

Hi Erik,
I am currently working on a LiveCD featuring emc2-2.3.0
The last version (aj12) seems pretty good, so here's the link:
http://www.linuxcnc.org/hardy/ubuntu-8.04-desktop-emc2-aj12-i386.iso
I didn't announce it yet on the website, as I hope for some more beta
testing before I do.

It sounds like you might have to reduce your motor max voltage

Hi,
Thanks for the help. I sure appreciate it.
I have every line working now except the two:

Any ideas what else could be the problem?

Also, you have a typo here, it should be sel0 instead of se10 (lowercase

Hi Stuart,
I don't mind the redundancy. Sometimes things are tried twice (or more) in

I haven't checked this yet, but I suspect that the PWM voltage to the

You didn't say what emc2 version you're using.
hm2-stepper has been reworked for 2.3.0, so you might have better success
with that.
(basicly it's using a similar code to the software step generator).
Try it out, but remember there are a couple of things that you can still do
to 2.3.0:

Having such a large FERROR is bogus imo.
Basicly you're telling the machine it can deviate 100 units from path, and
you don't mind...
It's probably less bad in mm, but still worlds away from a precise part.

Rob,
Have you tried adjusting FError and Min_FError? You can increase
Alex,
Well yea, then start backing it back down. But I got fooled on that because
I did not increase FError enough to see a difference, and hence started
looking at other parameters. Sort of like he is doing now. This is just
proving that FError is the parameter you want to look at adjusting.

That is just the initial check-in, but if you read the comments at the
beginning of schedrmt.cc you will see how it works, or at least should work
once everything is tested. Basically what it does is talks to another new
module emcsched.cc which schedules programs (i.e. gcode files) to

You dont need a BASE_PERIOD for hostmot2 - the base thread is in the FPGA.
Your SERVO and TRAJ periods are both 100,000 ns, which is pretty
aggressive, 1,000,000 ns is more
