Peter C Wallace, is there a way we could make a fixed duty cycle of
50% in the 5i25 while allowing the variable frequency we need?
For testing you can do this by selecting

I buy a lot of stuff from McMaster Carr too and like Albany the

Thank you John! I greatly appreciate shared links to good sources for
materials, tools, etc.
I've been buying most of my fasteners from McMaster-Carr. When I need
5000 or more, I try to buy direct but it's a hassle. McMaster-Carr is a
good source for prototyping and buying a few fasteners
Gene my DM 860 s count on the rise and fall . screwed with me for 2 days .
I had to double my micro step number in PNC config to get repeatable
indicated readings.

I wondered about that, since the matching DM542's don't. I am not done

Greetings all;
I am now calibrated well enough that I can actually run wood carving
code! And it looks like I could crank up the feed rate a bit, but the
finish obtained will determine that.
The comment someone made about that BOB being slow, depends on the
polarity of the pulses. Using a

I might have a lead on the two problematic PWM pins.
P8.36: All of the docs that I've seen don't show this pin being assigned to
a pru. Does this mean that it isn't available to use with the PRU based
pwm generator? It looks like it might have been used with the build-in pwm

The only problems I have had with pins is when I assign more than one
thing to drive them (ie: both the PRU and the hal_bb_gpio driver) or
get the muxing wrong in the device tree overlay.
The PRU can talk to any GPIO pin on the device, as well as the

Hi Charles, and all,
My BBB is making my printer move, and I'm almost to a place I can use it to
make something. The system consists of a bunch of jumper wires from the
BBB to a RAMPS board. Functional, but messy.
The next steps are:
1) Tweaking the temperature code to match the thermistor
