Nice teaser for the next installment of his MAHO retro in this weeks TOT clutch video. He really has a talent for telling a story and explaning.

Yes he does, and there are plenty others who try to do what he does, but not nearly as good.RotarySMP wrote: Nice teaser for the next installment of his MAHO retro in this weeks TOT clutch video. He really has a talent for telling a story and explaning.

Yep. I try not to copy his comedic chop's, because he's unique. But the basic concept of showing the project and not putting you own ugly mug in front of the camera is a good one, when you have a face made for radio, like me

He does have one single video where he is full frontal.

Some eagle eyed veiwers were not yet asleep at 10:10 of the last video, and picked up that PNCConf reset the PWM = 1 --> PWM =0 as soon as I exited that field. I have since tried it a few times and it seems like a bug ( or more likely a simplification) in PNCConf, as with the default firmware, there are no PWM available.
I assume I'll just have to edit the PWM manually into the HAL.
I read that the 1 PWM config of the 7i96 normally assigns it instead of Step/Dir 4 to TB2 pin 1-6. Is the PWM signal output between GND and STEP4+, between GND nd DIR4+, or between STEP4+ and DIR4+?

if you use the latest mesaflash:
github.com/LinuxCNC/mesaflash
you can list the terminal connections by using the --readhmid option:
mesaflash --device 7i96 --addr 10.10.10.10 --readhmid
For example, using the 7i96d_1pwm firmware, you get this listing:
github.com/LinuxCNC/mesaflash

mesaflash --device 7i96 --addr 10.10.10.10 --readhmid
