I changed out nearly every part of my controls. I kept the original psu and thats about it. I started out with an MKS-TFT 3.2 but scrapped it for the reprap full graphic display because it was using up too much of seial line bnandwidth. My new setup has fystech tmc2130 drivers in spi mode so i needed actve cooling for the stepper drivers. this case has dual 40mm fans to do the job. a third 40mm fan is used to cool off the bed mosfet unit, which is the typical no name black pcb mosfet yoy find everywhere. so no need for a rear facing fan as it would just clutter up the box. I moved the wire inlet hole from the bottom to the top corner for easier wiring. The original psu doesnt line up witht the holes in old or new case, and i really didnt care to change that after i got everything else the way i wanted it. I have included 3 different screen designs. the orignal fro the reprap, one that works with the cr10 screen, and one for the mks-tft if anyone needs it. feel free to mix and match parts from this and the original case design.
