$45 All-in-one klipper and klipperscreen upgrade solution for most printers

This is an all-in-one klipper and klippercreen package that uses a BTT pi v1.2 as a budget alternative to a raspberry pi and TFT35 SPI as a touchscreen (The TFT35 SPI actually isn't very good at all: the touch function can sometimes take 3 tries for it to sense).

BOM:

1. btt pi + TFT35 SPI https://vi.aliexpress.com/item/1005006340636804.html?spm=a2g0o.order_list.order_list_main.10.1bd21802eyKS77&gatewayAdapt=glo2vnm
2. Or you could not use the touchscreen: https://vi.aliexpress.com/item/1005006042755049.html?spm=a2g0o.productlist.main.3.612d5b5ek1Jh1Y&algo_pvid=3869be12-20f7-4f9e-a40f-ec34b46b529d&algo_exp_id=3869be12-20f7-4f9e-a40f-ec34b46b529d-1&pdp_npi=4%40dis%21AUD%21142.34%2142.70%21%21%21679.10%21203.73%21%402101effb17176457002707903ee229%2112000035456316898%21sea%21AU%213008025678%21&curPageLogUid=eOzMEQnbcGY4&utparam-url=scene%3Asearch%7Cquery_from%3A
3. M2x10 Self tapping screws (to mount the pi) https://vi.aliexpress.com/item/1005005730916402.html?spm=a2g0o.productlist.main.11.2cda5482lqzjPZ&algo_pvid=a46a3bc8-9fb8-4a97-bf7e-a88994e099e7&algo_exp_id=a46a3bc8-9fb8-4a97-bf7e-a88994e099e7-5&pdp_npi=4%40dis%21AUD%212.11%211.97%21%21%211.39%211.30%21%402101fb1617176466264771727ec748%2112000034145006285%21sea%21AU%213008025678%21&curPageLogUid=9Cdj0f9CJZcz&utparam-url=scene%3Asearch%7Cquery_from%3A
4. Something to power the pi: I used some cables that I ran to the printer's PSU and powered it via the screw terminals but you could also power it with USB.
5. Optional: 4010 or 3010 (4010 is better) axial fan (highly recommended: without it the pi ran at ~49-50°C, with the fan it runs at ~35°C) https://vi.aliexpress.com/item/1005003878405207.html?spm=a2g0o.order_list.order_list_main.16.1bd21802eyKS77&gatewayAdapt=glo2vnm   (use the 24v dual ball option if your printer has a 24v PSU, or you could use the 5v option and power it from the pi, but I haven't tested that)
6. If using TFT35 SPI or a fan: M3x12 BHCS x10 https://vi.aliexpress.com/item/1049664013.html?spm=a2g0o.productlist.main.11.72bb4e5cmxhN0g&algo_pvid=f89bb02a-4395-44d8-b4a5-9f44f77f8989&algo_exp_id=f89bb02a-4395-44d8-b4a5-9f44f77f8989-5&pdp_npi=4%40dis%21AUD%213.53%213.53%21%21%2116.85%2116.85%21%402101fb1017176462944315852ef26c%2112000037963538068%21sea%21AU%213008025678%21&curPageLogUid=nBh8griuPNne&utparam-url=scene%3Asearch%7Cquery_from%3A
7. some glue (I used a hot glue gun)

What files to print

1. case for the btt pi: "Case_main_part.stl"
2. to mount the pi case onto the aluminium extrusion “T-nut_extrusion_mount_x4” (I printed 4 and attached the pi case on the side of a 4040 extrusion)
3. if you are not using the TFT 35 SPI: "Top covers without screen mount" and choose the option that matches what fan you are using (4010 fan, 3010 fan or no fan)
4. if you are using the TFT35 SPI: “Top Covers With TFT35 SPI mount” and choose your fan option
5. If you are using the TFT35 SPI: “TFT35S SPI mount v2”

Tips:

1. it might also be a good idea to set up a webcam: https://www.amazon.com.au/dp/B07MK2LB66?psc=1&ref=ppx_yo2ov_dt_b_product_details and use octoeverywhere for AI print failure detection and remote monitoring (it works really well)
2. KIAUH is as good as everyone says
3. Orcaslicer is also as good as everyone makes you think
4. using the voron docs helps heaps (just remember to alter it slightly for whatever print that you are using
5. 1GB of RAM is enough for 1 printer with 1 webcam running at ~10fps
6. If you want to print faster it might be a good idea to upgrade your part cooling
