Why do you think the PITFT50 offered by Amazon is the TFT35?
I have several of the PITFT50 and they work fine in KlipperScreen when attached to a Raspberry Pi 4B host.
As far as I know, the TFT35 is not supported by Klipper as it would have to be connected to a controller and the Klipper controller firmware does not support the touch screen/graphics. It is to be used in printer with traditional firmware.
Uh I honestly donât know? I assumed it was a mistake someone putting up a dozen ads and copy/pasted descriptions? I really donât know.
Thanks for the explainer on the TFT35, Iâll be looking at one of the 3.5" on the list above.
I have the same BTT tft 35 spi screen but I have the skr mini e3 v3 board. Iâm running Klipper off a BTT CB1 and PI4b adapter. Iâm not sure exactly how to hook this up. I guess Iâll have to order the IO2adapter interface. I was hoping there would be a way without it but I donât think so. Any suggestions would be great. Thanks
Waveshare 7.9" Capacitive Touch Screen
I just bought this and can confirm that it indeed works perfectly fine when using the correct config.
Required kernel args:
video=HDMI-A-1:400x1280M@60e fbcon=rotate:3
This assumes the display is used in landscape mode with the hdmi port facing up.
THIS screen works with klipperScreen on my Debian 11. No config changes needed, just plug and play.
Elecrow 5 inch Resistive Touchscreen
Generic Chinese 5" Screen, pretty low form factor with Pi mounts on the back.
Itâs a bit of a process, but itâll work in the end. The below instructions will install the drivers correctly and rotate the screen 180.Leave out the #Rotate Screen# section if you donât need it.
#change wpa supp right after writing the OS to the SD card#
#Install SD card into Pi and boot up, allow Pi to connect to network#
#SSH to Pi#
#run driver install #
git clone https://github.com/goodtft/LCD-show.git
sudo chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD5-show
#rotate display 180#
cd LCD-show/
sudo ./LCD5-show 180
#Install Kiauh
sudo apt-get update && sudo apt-get install git
&& git clone https://github.com/dw-0/kiauh.git
#Install KlipperScreen with Kiauh
./kiauh/kiauh.sh
#paste last part of the below mainsail config into config.txt, all the way at the end#

THIS screen worked out of the box with KlipperScreen. No instructions were included, but it appears to be a clone of the Waveshare 7" HDMI touch panel.
was it plug and play ??
Mine is still not working 
Hi! I tried to follow the instruction on the link but then it ended up preventing my Raspberry Pi from booting into KlipperScreen. Everything was working fine before I tried to install the drivers and now it does not boot up to KlipperScreen at all anymore and just goes straight to the Raspberry Pi command line. Is there anything I did wrong?
Sorry if this is a dumb question⌠Where, or what file, did you add this code to? Plugging it in, makes it work just fine in portrait mode. Tried:
Section âMonitorâ
Identifier âHDMI-2â
# This identifier would be the same as the name of the connector printed by xrandr
# for example âDVI-I-1 connected primaryâ means that the identifier is âDVI-I-1â
# another example âUnknown19-1 connected primaryâ some GPIO screens identify as Unknown19
Option "Rotate" "Right"
# Valid rotation options are normal,inverted,left,right
#Option "PreferredMode" "1920x1080"
# May be necesary if you are not getting your prefered resolution.

Was able to rotate screen, but the touch I couldnât get to rotate.
Apologies to be responding to a very old post but I felt it was worth mentioning that I was able to get this screen working without all the fiddling (which I used to do, annoyingly) after I installed a firmware update that waveshare posted at some point after I gave up using it reliably. While the firmware is to enable adjusting screen brightness through software, it seems to have ironed out the EDID, or whatever, issues common with this screen, at least in my recent experience. Firmware is in the link under Method
You do need the more recent version of the screen with the touch rotation and power buttons (two closely stacked vertically to each other), I wasnât aware of an earlier model, I bought this one in 2019 I think. As far as I can tell, thereâs only an EXE to install the firmware, so Windows access also.
Also to note theyâve added a good bit of extra info in this wiki since last I visited it. I can say that I now have this amoled working after basic rotation setup. Smooth scrolling, too. Maybe this is updates from KlipperScreen recently, but I did try it during a new install and it was up to the same issues pre-firmware update in summer '24. This is on a debian 12 installation as well, MiniPC, but the issues were identical to a raspi4 it used to live on before I migrated to the miniPC, so I cannot say if the same will work on debian 11 if anyoneâs using that, nor 100% confirm itâs a raspi fix yet, but I will test and report. Since itâs an easy firmware update, figured itâs worth a shot to anyone with the screen. I hope this helps.
Hosyond 7" Touch Screen- Confirming success. See notes below:
Add this text to your config.txt file:
max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=7
hdmi_group=2
hdmi_mode=87
hdmi_drive=1
display_rotate=0
hdmi_cvt 1024 600 60 6 0 0 0
And then, if you want to rotate the display like I did, you will install the LCD-show driver and use that to rotate the display. Iâm not sure why you canât just use a different display_rotate value in the config above, but the following commands worked for me:
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD7C-show
cd LCD-show/
sudo ./rotate.sh 90
I set it to 180 instead of 90. You can also use 270 depending on your desired orientation.
Note- This screen requires both an HDMI output and a USB data connection. Depending on your model of Raspberry Pi, this could add to the saturation of your USB channels. I have a rpi 3B+ and when I run a timelapse at greater than 640x480, I experience frequent âLost communication with the MCUâ errors that cause my print to fail mid-print. Hard to confirm as nothing definitive in the logs, but my going theory is that the USB channel gets flooded to the point that it drops the critical connection to the MCU. This is solved in a variety of possible ways: 1) Set a low resolution and framerate for Timelapse. (eg 640x480, 10fps). 2) Turn off timelapse. 3) Disconnect the HDMI and USB for the touchscreen when running a higher res timelapse 4) I have a hypothesis that a newer model rpi will also fix this problem. I plan to upgrade and test this theory soon.
Final note- 7 inches actually feels a little oversized for a 3D printer control. Itâs more resolution than I need for Klipperscreen, and a smaller screen would be easier to mount and work around. If I were to do it again, I might shoot for a 5-inch touchscreen with a DSI connection, for example, one of these:
5 inch touchscreen with DSI from iPistbit (Links in this post are Amazon affiliate links)
I agree. I prefer these. They work well and supports DPMS.
This is not KlipperScreen specific, but I am posting it for the benefit of others who may be struggling to get the Waveshare 4.3" DSI IPS screen to work with recent releases of Pi OS.
Older versions of this screen use Waveshare touch controller (translator) chip WSTPA0 (ex. date code 2015) that is not completely compatible and will not function with the vc4-kms-v3d overlay.
For those screens, either the deprecated vc4-fkms-v3d overlay has to be used for touch to be functional, or a replacement WSTPA0 chip with date code 2451 or newer needs to be sourced from Waveshare and soldered onto the display PCB.
Hi,
I have an Orange pi 3b with bookworm server on board i attached to It a btt HDMI 5.0 v.2.1 and the monitor turns on but remain black.
Is there something wrong with config?

Iâm at the point of buying a BTT Pi TFT50. Does DPMS or sleep mode work correctly with this v2.1 screen? Iâve been reading different things, but theyâre from more than a year old ago.
I just would like the screen to go to sleep when not in use and maybe wake up after touching it?
