It uses the BL Touch probe for G29 autoleveling - you can also use one of many BL Touch clones like 3D touch. The rear plate has space for an ATX computer-style power supply and a standard power connector/switch if you prefer a meanwell instead. Simply omit the one you won't use when doing CAM work before cutting. The frame is built from 9mm thick material - I used stained Baltic Birch. You'll need a 1/8" bit to cut this on a CNC machine. Be sure to check out the attached picture for special considerations when cutting the bottom plate of the machine. Here's a video of the printer in action: https://www.youtube.com/watch?v=4t9eIk2gnUA I used the E3D Titan Extruder, but you can also use an mk8 extruder gear and the file I included here instead. The Bill of Materials is a rough adaptation from the original MicroRAP 100, so proceed with caution. I chose to use a 4510 blower fan that's lighter and more compact than the popular blower. The 4510 blower can be hard to find in 12V, but there's one for sale here: https://www.ebay.com/itm/192569600144?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
