I have a custom 3D printer machine, very similar to a CNC (600x450x400 mm) with a Mach3 Ethernet controller board. Sadly I've been experiencing problem since day one, from layer shifting to pc client crashes (due to Mach3 program), so I decided to move to a controller board designed for 3D printer.
I'd like to use Duet3D hardware, since everyone agrees they are the best, but I'd like to keep most of the hardware I already have, especially stepper drivers, which are very good, almost professional level.
Here there are the main constrains:
-Main power line is 24V (shouldn't be a problem).
-Inductive edstops require 12 to 24 V power supply.
-Extruders and bed heaters are powerd by an external power supply, through SSRs (so I think I can connect the board to these relays)
-Fans are 24V powered.
-I'd like to have more IO (e.g. for a filament encoder and start/stop external buttons) but it's not essential.
I've done some research and I think the main problem is having at least 3 (X, Y, Z) external stepper drivers as the majority of 3D printer controller board are designed to have them built-it. Alse very few boards support 12V or 24V for endstops and IO.
Thanks in advance
