I'm using a BTT PiTFT50 with a Raspberry Pi 4B. KlipperScreen is displayed but touch is not working. I have found two errors in KlipperScreen.log: 2023-07-27 10:05:46,282 [KlippyRest.py:send_request()] - host=127.0.0.1, port=7125>>Max retries exceeded with url>>Failed to establish a new connection>>[Errno 111] Connection refused 2023-07-27 10:05:57,190 [KlippyRest.py:send_request()] - 404 Client Error>>Not Found for url>>http://127.0.0.1:7125/machine/device_power/devices
Apart from that, I went to boot/config.txt and changed dtoverlay=vc4-kms-v3d to dtoverlay=vc4-fkms-v3d. Still not working. Also I went to raspi-config and enabled SPI and I2C. Any ideas?
