Note 1:

When I built this printer. The control board port numbers in the steps of the instructions did not match the port numbers on the control board diagram. Most were like one number off. The diy.pdf on this site has a really good diagram of the control board: https://qbism.com/viewtopic.php?t=21. I used it for all the wiring.

Note 2:

The stock extruder is wimpy, so you should print and build this extruder replacement upgrade.
(I purchased a similar one, but had to modify it to make it work with the printer where this one has been designed to work with the printer.)

Note 3:

I recommend you print my remixed replacement top brackets to fix Z-Axis Wobble on the printer.
