Controller details

Are you using the stock buildbotics based controller? If yes, what at all has been modified?

For the plotter stuff, I was using the stock buildbotics controller.

For 3d printing, I looked into the possibility of using a standalone heater controller and driving both Y-steppers with a single driver to free up Y' for the extruder motor, but it turned out to be both easier and more cost effective to just switch to a different controller altogether. I'm now using a BTT Octopus running Klipper which easily drives more axes than I need as well as multiple heaters and fans and such without much fuss.

The biggest issue right now is heating the giant glass bed. I'm currently using an 800W heating coil and it's not nearly enough. Next steps are going to be improved insulation below the coil and potentially a second 800W coil.

Do you have the pin layout diagram anywhere, or is it self explanatory on the controller board? I'm excited to give this a go. At first I'll just use the print volume of my heated Ender board until I can figure out a larger heated bed volume.

Pin layout and info to make cables. I highly recommend making a set of nice cables with the proper end connectors. Troubleshooting "is something really broken or are my makeshift cables loose again?" isn't much fun.

A (crappy, not very rigid -- I really need to redesign this thing) Hemera mount that attaches to the front of the spindle mount.
