Retrofit: Maho MH400E to LinuxCNC
Category: Show Your Stuff
Got the Mesa 7i94T and 7i77 boards powered up today, and it’s great to finally see the pins show up in LinuxCNC.
Also managed to remove the tool holder that had been stuck in the spindle since I got the machine — definitely satisfying to get that out of the way.I’ll shorten the IDC25 ribbon once the board layout is finalized. For now, I’ve ordered breakout boards to avoid cutting cables too early: three for the Heidenhain DB15s, two for the Indramat DB9s, and two for the IDC40 ribbons.
The original Philips 432 hardware is completely gone. I briefly considered replacing the whole cabinet to avoid upgrading the mains fuse, but in the end I’m likely going for a proper electrical upgrade: increasing the main connection from 25A to 40A and switching from a B16 to a C25 breaker (still waiting on the electrician to confirm this setup).Once the wiring takes shape, I plan to capture everything neatly in EPLAN to avoid spaghetti later on. Slowly but surely, things are coming together.

Thanks, Mark. It's going slow but steady.
I can't forget you saying "and basically, that's it". Yeah, if only.

neeed help with additional pwm 6i25 and 7i76
Category: Basic Configuration
I'm trying to get this working. Ive read most of the other relevant threads and the documentation.
I have flashed the 6i25 with 5i25_7i76x2pld.bit
here is my hal and these are the only code i have that references pwm
i get this error
/Laser.hal:26: parameter or pin 'hm2_5i25.0.pwmgen.00.pwm_frequency' not found
and also tried halshow
