Hey. I am looking at the wiring for the extruder head. It seems as though the 4-way pin header is an optional thing, as I read from the Mendel extruder head document page. So I don't have to order more parts, and to save time, is there a quick work around for wiring the extruder head without using the 4-way pin headers? Thanks for the help. My machine is coming along very well. - rusdp https://reprap.org/forum/read.php?151,41988,41988#msg-41988 Sat, 10 Oct 2026 16:02:37 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,41988,42227#msg-42227 https://reprap.org/forum/read.php?151,41988,42227#msg-42227
The little prototype board with the 4 pin connector is entirely optional like you say. For my mendel I connected my extruder's stepper and thermocouple board (optional add-on, same applies for thermisters though) directly to the extruder board. The 4 pin header board just reduces wiring clutter, same with the power connector/usb connector board thing. A standard ATX power supply and FTDI serial<->usb will work just as well, it'll just be a little messier :)

Cheers,
