## Updates - 7/25/2020: Added version for 25A [Aliexpress MOSFET](https://a.aliexpress.com/_B0CGtZ) by request, dimensions for ~ 42mm X 52mm between 3mm mounting holes. To make room I had to remove provisions for the relay. For this version you need to print the version of the cover WITHOUT SSR - 5/22/2020: Uploaded Axis Clamps Less Wires.stl for holes like for the bed where there aren't so many wires so they're clamped securely in place. Also added another with even more meat to it just in case as well as a boot meant to be printed in TPU (named TPU Boot.stl) ## Taz 4 / 5 32 bit SKR 1.4 / 1.3 Upgrade Electronics Box This is meant as an electronics enclosure for my Taz 5 32 bit upgrade to a BTT SKR 1.4 Turbo, it uses the original connector from the power supply and the original power switch and that's about it. To do this upgrade you'll need to change out the connectors on the board side to adapt the wiring to the standard RAMPS-style JST-XHP 4-pin for the steppers and 2-pin for fans and thermistors. I made a more detailed write-up on my GitHub pages [over here](https://jimbalny.github.io/Taz5SKR1.4.html) which I'll transfer over here when I have the time. To avoid putting stress on the SKR's onboard MOSFET I chose to go with an Auber 100A DC-DC Low On-Resistance Solid State Relay as well as a 25A External Heatsink. I did this so I could easily change it out to an AC SSR for when I change the bed heater over to 120v. For the brave amongst us you can use the onboard or an external mosfet, I provided an additional STL without the cutouts for the SSR as well. I realize this is a lot of work to upgrade a Taz to a 32 bit mainboard / silent stepper drivers, but the cost of everything including the board, drivers, TFT35 v3 touchscreen is much cheaper than the Archim direct RAMBO replacement board. This was a project of necessity as my RAMBO was starting to act up, the motors were doing weird things and the connectors for the X axis stepper was starting to heat up so a complete rewire/revamp was in the cards for me. This project is the result of about a month of planning and 3D modeling just about everyday after a hard days' work in NYC between printing face shields and drinking lots of coffee. So if this helps you out please consider hitting that tip button to help recoup some of my coffee / filament cost :) ## Progress ### To-Do - Re-design back section for TFT35 v3 from the [design I used](https://jimbalny.github.io/Taz5SKR1.4.html) by request, dimensions for ~ 42mm X 52mm between 3mm mounting holes.
