I purchased a new 4.2.7 (256k) board for my Ender 5 Pro and added the CR Touch. I got everything connected and flashed the board with the "Ender-5 Pro- Marlin2.0.1 - V1.1.1 - ALT - TMC2235.bin" firmware from the creality.com/download > Accessory Firmware > CR Touch Firmware for 32-bit Motherboard > Ender-5 Pro.zip
When told to Auto Home the Z-axis drops 5 mm then checks X-axis & Y-axis endstops = OK
But then the Z-axis drops another 3 mm and the CR Touch deploys > Retracts > deploys > Retracts and Faults out.
The instructions say to move the Z-axis to get the offset but it will only go down while the CR Touch is faulted (Stopped)
I've checked all wiring made sure the Z-axis endstop was disconnected. No help.
Thinking it was a board issue I wanted to check the normal, no CR Touch, functionality, so I flashed the Marlin2.0.1 V1.0.1 original versionTMC2225 "Marlin2.0.1 - V1.0.1 - Endstop - TMC2225.bin" firmware onto the board, and reconnected the Z-axis endstop. The printer worked like normal.
Not wanting to fail, I decided to try another firmware, so I decided to use TH3D_Unified2_CrealityV4X_256K. I went through and set up everything using
CUSTOM_PROBE settings. And wouldn't you know it... SAME Results as with the Creality "Ender-5 Pro- Marlin2.0.1 - V1.1.1 - ALT - TMC2235.bin" firmware.
Bed drops 5 mm at the start of Auto Home then drops another 3 mm after centering to deploy the CR Touch. The CR Touch deploys > Retracts > deploys > Retracts then Faults out. At no point does the bed ever try to go up.
The only other thing I can think of is that the CR Touch isn't working right. I thought it was supposed to deploy then the bed was to come up to it to detect it. Could the wiring "harness" for the CR Touch be incorrectly wired? (Wiring below)
Can someone help me with this one? Do I have a bad Board? Do I have a bad CR Touch? Or am I just not getting a setting right somewhere?
