Hello,
We work with laser cutting and engraving machines, however we have not tried
them using EMC as it would need a long conversion job. We have other milling
machines run with EMC and they all work very well.
We have a new router though onto which a laser tube should be put and the
machine cou

I think the above configuration change should fix the problem you're

specifies both an [AXIS_?]MAX_ACCELE

Yes, I am using 2.3.0. The version I compiled from CVS end of last week

Perhaps a good candidate for a router mill for cutting wood perhaps?

I think so too - sure looks nasty though. I bet you will have much
better luck with 2.3 (this effect is why I rewrote the threading

Andrew,
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 exe

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.

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

Maybe just as easy(?). Remove the hard drive from the machine that
won't (isn't) booting the CD and install it in the box
that can come up under 'Live'. Go thru the installation process and
then move the disk back to the other machine.

Dirk,
I have been using EMC to do both cutting and engraving with lasers. Cutting
is pretty straight forward, engraving is a bit tougher depending on the type
of engraving. Fixed power engraving isn't too bad, i.e. the case where
whenever the laser is on, it is at a single power level (obviously y

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

One more redundant question. When you boot MachineA from the CD are

MachineA and put it into MachineB?

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

My first guess is that configure did not detect the necessary packages
to build the parts of emc2 that require Python -- hal_manualtoolchange
is one such part. If configs/sim/tkemc.ini works, that would tend to

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:

Is anyone running the R990h boards? I can't find the step time/space and

comes alone...
