ELECTRONICS ENGINEER?
Is there any electronics engineer in this group who would be able to help me by designing some, what I think ought to be fairly straightforward, circuitry for a project I'm working on? I'm creating a new type of 3D printer that needs to control some additional hardware. I've written a substantial amount of the software, modifying open source slicer code, but I need the circuitry interface between the printer CPU and the several devices I need to control.
