Rostock 3D Printer
My Rostock 3D printer is a custom-built deltabot 3D printer. The frame and motion parts are Trick Laser's Max Metal parts, the hotend is a Prometheus V2, and the control electronics are a BeagleBone Black with a Replicape. Having an embedded Linux computer in the printer makes it super customizable, and ssh'ing into and messing around in the printer is comfortable for me. Pairing some 0.9 degree NEMA 17 stepper motors with the Replicape's Trinamic TMC 2100 stepper drivers results in silky-smooth, high resolution prints, and the printer is whisper quiet. I intend to incorporate a touchscreen display in order to take advantage of Toggle, a touch interface that comes integrated in Kamikaze Debian image. (Note: a previous iteration of the printer is shown in the above video, which was controlled with a Smoothieware based controller. 3D printable files can be found in my repo. )
While the Max Metal frame is a solid foundation, it does not include any mounting points for anything aside from the stepper motors. For the top of the machine, I designed simple mounts for the endstop switches, as well as a horizontal filament spool holder. The adapter is interchangeable to accommodate other brands of filament, and it has press fit standard skateboard bearings for low friction. In addition, I designed a filament guide to prevent the filament from falling off the bottom edge of the spool and tangling.
For the bottom of the machine, I designed some simple mounts for the power supply. I also made a cover for the live end of the power supply that also serves as a mounting point for a power switch and power socket. To mount the bed, I designed a set of parts that wedge into the slots in the corners in the frame. The bed screws go into these three mounts. I also designed a part that wedges into the slots for mounting the BeagleBone Black and Replicape. I am currently working on implementing a fan with higher airflow for better cooling of the Replicape's stepper drivers.
In addition, I designed and printed some fan shrouds that serve to direct the cooling fans' airflow towards the parts being printed, while keeping the air from cooling the heater block.
