I just looked at the particular .ini and .hal files, and, I am sad to

Just let me know when it's done. I'd be happy to cvs the new sources

I changed the hm2 stepgen and maxvel to values that are a bit higher
than the AXIS_ values

I think the above configuration change should fix the problem you're
seeing. Take a look at the "stepper/stepper_mm.ini" config, it
specifies both an [AXIS_?]MAX_ACCELE

Yes, I am using 2.3.0. The version I compiled from CVS end of last week
so the one without the humming and dithering in the motors.

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.

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 FError by
quite a bit, say 100 or higher if necessary. In my case that got rid of most
of the following errors. The one instance I would still get them is in a
sequence of G0 moves, such as retract, move, plunge (I am using a l

The "elan" config is the old parport config, hm2-stepper the hostmot2
stepper motor config.

Hi,
the past week(s) I have been working on getting my hostmot2 system
running with the Mesa 5i20 card and stepper motors.
Up to a certain point this is a success. But there still is this problem
with joint following errors - whatever I try I keep having joint
following errors.
