Sorry been busy today and just saw this.
I bought a 2nd hand touch screen (3M Microtouch). A part from being
cheap, $25 AUD I figured it would be a fairly rugged piece of kit (very
little use). So it's only 17" but with the lack of space in my work area
it fits right in. Touch a little bit of
Hi Gregg,
My observation is that in the last decade or so human factors engineering has
taken a back seat to getting a product out the door. Possibly with the idea
that it will be out of date in a couple of years so why bother.
Way back when I was in University it was the Arts Department at
That's what I've based my wizards on. I started using that version, but had
trouble laying out the screen using python and the toolkit it used. I ended
up writing a c++ version with preview, but that never got pass a beta
version.
My old lathe wizards are here...
That sounds like you could have to much Kd. Try reducing it. Do you have
an oscilloscope? An oscilloscope really helps when tuning servos. As the
UHU doesn't have an analog output you would have to probe the motor
drive signals. Put a simple R-C filter in line with the probe to filter
out the
That 0.5 uS spec is for the minimum time the clock needs to be low.
STEPLEN is the time to remain high. You have STEPSPACE=0 which means the
low time is to be "0 nanoseconds".I'd make STEPSPACE much larger.
BTW, that L297 is primitive at best. You'd be amazed at how much better

Hi,
i try to reactivate my old self-build cnc mill with stepper motors and
come to a little problem. My 15 year old electronics seems all still to
work. It uses L297/L298 stepper drivers driven by the parallel port from
my old pc which is quite outdated but this doesn't matter at the moment.
I
Thanks for the hint. I will try to set stepspace at a higher value.
And i know about the newer Drivers. I already use DRV8825 for a new
project and it is far superior to the old L297/L298 combo.
At the moment i just want to get the old hardware running and i already
have planed to replace the
So i tried setting stepspace = 1 but no change. Then i tried setting
both steplen and stepspace to 1 and also no change. It seems as if
LinuxCNC ignores my values.
When i open HAL Meter and show the current value it shows me 75000 for
both of them. But this would mean 75µs pulse width

Thanks for the hint.
This parameter is not quite the one i would have looked into. After i
changed it from 5000 to 1 the pulse width changed from ~3,2µs to
~4µs. And with a value of 2 i get ~7µs which is enough to work with
my old stepper driver. Interestingly when i set higher values

grbl is best compared to the "Marlin" software that drives most 3D

similar in many ways.
1) Marlin and grbl both run on Arduino, even the low-end "Uno".
2) They are VERY efficient because the configuration is done in the

Thanks everyone,

I could get rid of that harmonic noise that sometimes comes up but only in one
direction. Nothing helped. I'm of the opinion that under load in one

Andy that's awesome!
Can I just open the sample install and test it?

I think so. It’s been a few years since I wrote it.
