    Sorry not seeing what board you've gone to. I downloaded the zip but didn't see a doc or text file listing the electronics. I'd love to try the same but driving the extruder heat etc not available on my current OpenBuild Mill board

    I’m using a custom assembly with a arduino mega for the brains, and leadshine drivers ( 3axis and single axis for the extruder). There’s also 3 SSR 30A relays for controlling the bed, and heater cartridge, and power. Everything is broken out on the back of Goliath, and tied to the extrusion.

    I’m running an upgrade right now, that should be done in a couple weeks. I’m replacing all of the plates with thickercarriages
    Hey Bigidiot419..Yea i've got some, but this was just a prototype.

    I'm working on a scratch build for a robotics actuator project that uses a hypo cycloidal reduction, and an axial pancake brushless PCB motor. I've been working on the controller side of it recently now that ive finished the reduction design. I just did a PCBA run for a custom BLDC driver w/ torque, position, and velocity control as well. So far its rated at 20 N.m., and coming in @ 450grams. BOM cost is sub $300. If anyone's interested, ill post a build on it.

    Here's the updated cad assembly, and some renders. I'm in the process of upgrading the x axis and carriages.
