It is a compile farm for the Marlin firmware, which is obviously for 3d

Jon,
It doesn't "switch" from 1/10 to full-step, it "morphs". It's not done
with clocks and dividers, its done more in the analog side. That's the
difference that Mariss adds. Anyone can built a microstepping drive. There
are scores of application notes and open source designs. To do what

It is a little unrelated to EMC but figured someone maybe interested.
I have been fooling around with a program for Arduino and will post a link to
the program when finished, the goal

A number of discussions have addressed software tools to generate G-code
mostly as part of another discussion..
1. Some of us are interested in starting from various mechanical CAD
programs and file formats.
2. Some of us are starting from existing graphics in various formats.

I suspect, and I may be way off base, the 2 RPS (
I use a chinese model with DSP, and it include 3 notch finder that kill

kill a mechanical resonance)
even using the microstep mode, if you need a really smooth motion, you
will notice that a standard stepper driver (even wit
You run it at a couple of RPS. Its the speed where you notice that its smooth

Then adjust the pot to get it as smooth as you can.

I think it works no matter what but it is smoother if you adjust it. I
forget the RPM you run the stepper at then tune for smoothest sound and
done.

Hmm, I put 6 G203v drives in the welding robot, but did not touch that
small tuning pot and the robot
The G203v's that I use on my plasma cutter are smooth as silk and when
you adjust the morphing pot you can really tell the difference when it
is adjusted correctly.

does anyone know what the relationship between linear axis units and rotary
axis units is? the matter is twofold: 1) feedrate. 2) jog increment.

The motor sees the change electrically, the interface to LinuxCNC does

I imagine it
I don't see how they could switch from 1/10 to full step without letting
LinuxCNC know, and having LinuxCNC reduce the number of steps being
sent, unless they used a clock multiplier, which would make it look like
full step to the control, and just use microstepping to smooth out the
full steps
Hi Jon,
Yes, the Geckos are one of the few drives that have electronic
anti-resonace built it. The other feature that improves the performance is
that they morph from 1/10 to fullstep as the stepper rpm increases. This
overcomes the deficiencies of using microstepping at faster rpms, and
gives
