BIGTREETECH Pad 7 Klipper Touch Screen 7 Inch 3D Printing Smart Pad Open-Source Klipper-preloaded with BTT CB1 for Ender-3 V2 Upgrade to Klipper, Compatible with CM4

Amazing display. Bright and readable. Fairly easy to configure if you follow the guide in the Github. It has worked flawlessly so far with my SKR mini e3 v2 control board.

At first I hit a little snag while setting up the firmware, as I purchased this in combo with an SKR 1.3 board to upgrade my sidewinder x-1 to 32 bit. Editing a fresh clone of Marlin firmware and following along with a couple youtube videos searching "skr 1.3 and tft 35 3.0" for some reason didn't mention that in order to be able to use TFT control in addition to USB/Octoprint you need to set two serial ports in marlin 2.0 configuration, namely #define SERIAL_PORT -1 and #define SERIAL_PORT_2 0 in Configuration.h. If you have issues communicating with the printer in marlin set your baud rate #define BAUDRATE 115200 and change it in the TFT's settings menu to match. The serial port config may vary for different boards. Hopefully this helps people who are having some trouble!As far as functionality goes, this is a great solution for quick control of your machine. Mostly use the touch mode for operations like heating up the extruder, changing filament, but don't ever print from sd card on it since I use octoprint so idk how well that part works. Being able to switch to classic marlin mode by holding the button down is great as you can still have all the extra menu options like TMC stepper settiings, ABL, babystepping, etc. BigTreeTech open sourced the screen's firmware and is pretty great about constantly updating, adding new features and making it look better. They just added encoder control to the touch screen mode which is a much welcomed change! The only other issue I encountered was stuttering coming from the encoder wheel that would constantly change my feedrate on the marlin info screen. I have read that it can happen if the TFT 35 board is screwed into the 3d printer chassis. But I was able to fix it by commenting out //#define ULTIPANEL_FEEDMULTIPLY in Configuration_adv.h to disable this function completely. Though after I grounded the mainboard and everything else better to the chassis I haven't noticed any more glitchiness, tho it can just be a coincidence. I love this screen so much I already ordered another to use in my Taz 5 SKR 1.4 Turbo with TMC 2209 and TFT35 v3.0 32 bit mainboard upgrade :)

I got this bundle version including the cb1 board with integrated emmc 32gb. You have to find the right guide online to install the image. The version using microsd card has everything already setup so that was almost plug and play. That version you just need to install the correct config and follow the YouTube guides to flash the printer firmware.For the emmc version you have to have an otg cable to flash the image onto the onboard memory. Took me quite a bit of time to find the right guide for setting up the cb1 with emmc.The first cb1 board has a faulty WiFi so that adds to the installation trouble. After I received the replacement setup was fine.The cb1 with emmc is not much faster than the sdcard version so might not worth the effort.

This was a very well thought out product by BTT. It works well right out of the box, has all the software you need to get going plus you can customize it in any way you want. The screen itself is responsive and easy to read. The CB is powerful enough for my use with Klipper. I've even been able to use the accelerometer for input shaping which was a surprise bonus.Highly recommend getting this product with the BTT SKR Mini E3 v3. If you are going with Klipper on an Ender 3 V2 then this is the way.

This pairs right up with the cb1 / btt pi 1.2. "Cheapad" was an amazing resource for this, but I ended up building my own firmware / config from scratch and copied in the tft spi config from the github. The screen has been working flawlessly and I cant be happier with how easy it was to set it up. FPC cable, blue side facing away from screen, and blue side facing away from skr mini v3 - booted right up.
