Hello again everyone,First, I apologize for the late reply — I’ve been working on revising my plan and wiring, and it took longer than expected.I’ve updated my wiring/architecture plan (see attached diagram), and here’s where I’m at:
- Mesa 7i92 over Ethernet
- Two 5-axis breakout boards (5ABOB ×2)
- DM556 drivers for NEMA34 motors (3.5 Nm, 3 A/phase)
- THC Proma 150 for torche height control (Arc OK, Up, Down signals)
- Relays for torch, laser, pump, etc.
- E-stop, limits, probe via optoisolators
- Power supplies: 5 V/8 A, 24 V/3 A, 36 V/12 A
On one BOB (P1) I plan to handle signals like Arc OK, Up, Down, E-stop, relays; on the other BOB (P2) I plan to handle limits, probe, and driver step/dir lines.Questions
- With that setup (7i92 + 2 × 5ABOB), is the wiring architecture I’m proposing feasible?
- I was thinking of starting with the G540 HAL/INI config in pncconf as a base, then editing it . Is that a sensible approach, or is there a better workflow to generate a clean HAL/INI for this sort of layout?
Thanks again to
PCW,
tommylight, Your help is very valuable. Any further feedback or corrections before I begin wiring would be hugely appreciated.
