Quotehddvrn Please connect the CR touch cable to the standard connector of the board. The printer does not see the sensor response. Yes, it is already connected all 5 wires to the Z-probe connector on the board. The clip above is using your firmware you have shared. That is the behavior it is displaying.by niblem - Firmware - Marlin
https://imgur.com/a/QdVhav9 Here is a clip of exactly what is occurring. I have the CR Touch attached to the Z-probe connector with all 5 wires and the Z-end stop is empty. I am using firmware that is known to work for others with Ender 3 V2 and CR touch and mini e3 V3 (HDDVRN's version). You can see when the probe is trigger, it flashes red but keeps on going and the nozzle will hit the bed.by niblem - Firmware - Marlin
[email protected] The only thing I can think of is to use the M43 S servo probe test to verify that the probe's signal is getting back to the MCU. In the LCD menu, if I choose Deploy Probe, it does in fact deploy and retract as expected.by niblem - Firmware - Marlin
[email protected] Here's a video that's very clear about how to plug in the wires for your setup: You would need to go back to using the Z probe as the Z end stop. Great video find. It does clearly show the wiring orientation for the CR Touch and the mini E3 V3.0 board. I have re-wired my CR Touch to match the video and I have re-compiled my firmware to look similar to that of the BTT offby niblem - Firmware - Marlin
My current configuration is as follows: I have now tried to connect the top 2 wires (Blue, Red) into the Z end stop connector. Previously, it was wired into the Z-probe connector as Blue, Red, Yellow, Black, White top to bottom. My firmware is compiled as follows, with the Blue/Red wires in the Z end stop: #define USE_ZMIN_PLUG, #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN, //#define USE_PRby niblem - Firmware - Marlin
So, is anyone using a CR Touch with specifically the Ender 3 V2 and the SKR Mini e3 V3? After solving my LCD problems listed above, I have tried multiple things to get the CR Touch to work but it continues to fail. Plugging it into the mini e3 board wired the same way as the 4.2.2 board, the probe is non-functional. When booting the printer, the probe will drop / deploy and fails to Z-home.

QuoteOren_Arg Looks like you didn't switched between RX-TX (black and white according to your scheme) Correct! After switching White for Black on the LCD, the screen is now working. Thank you very much. Now to figure out why my hotend fan isn't workingby niblem - Firmware - Marlin
QuoteDust "On the mini e3, there is a red status light that blinks, and a green light comes on if an SD card is inserted" so the printer booted, the screen not coming up is not the same as it didn't boot. The display is just a serial device. Check the wiring on the Orange and purple wires on picture above This is how I have my custom wiring. Does this seem correct?by niblem - Firmware - Marlin
Friends, I am having similar issues as hddvrn was having, as I have an Ender 3 V2 and upgraded to the BTT SKR mini E3 V3.0, but I still cannot get the printer to boot. I followed along with this thread, and used your firmware file you listed and was able to compile it successfully. After flashing with an SD card, the file changed to Firmware.cur, so I assumed that it was successful. I also flby niblem - Firmware - Marlin
