Sorry this is lengthy but I want to give as much info as possible. I have an Ender 3E (Creality page doesn't even list it). It has the 4.2.2 motherboard running 126.96.36.199 software. I purchased a 3D Pad Mini. The instructions are inadequate at best. I downloaded the 3D Pad Mini Package. It had 2 options for the 4.2.2; 2.Ender-3 Pro-HW-V4.2.2-SW-V188.8.131.52-CRTouch (don't know if CRTouch is the same as BL-Touch) 4.Ender-3Series_HW4.2.2_SW184.108.40.206_SWPB Since I don't have a Ender-3 Pro I put the #4 file on a blank 8gb micro sd. I installed the 3D Pad Mini, put the sd card in and powered on the printer. The UI came up and no indication of the flash starting. I turned off the printer and put in another sd card with the .tft file and watched the progress info until "Update Successed!" message. I turned off the printer, removed the sd and restart. It communicated and I tested Home and some XY movement. Z would not move below the home position, about a 1/2 inch from the bed. I tried the Auto Level and it would do nothing, and if I print, it starts about an inch above the bed in air, I powered off the printer and renamed the .bin file to Firmware.bin then powered on the printer. The UI came up and no indication of the flash starting. I found and downloaded Ender-3Series_HW4.2.2_SW220.127.116.11_BL_TOUCH file. I tried to reflash my Ender 3E, the UI came up and no indication of the flash starting. I put my original screen back on to try the flash and it only has a blank blue screen. Nothing else. Back to the 3D Pad Mini, I tried to flash again and get no response. Tried to print and it is printing in air. I cannot seem to flash the firmware. I sent a reset code M505 and a save code M500. No responses. I tried to find a way to check my printer firmware version. Can't find an option on the 3D Pad Mini. Downloaded a different 3D Pad mini Screen firmware.tft and loaded it. After reboot, I have a completely different leveling screen. Now it will try to auto level, it checks the center correctly (two bounces and BL light goes from blue to red) then moves to the front right corner, light turns blue then it raises and returns to center and stops. The original auto level went from center to front left. From the Home position, I set the Z offset to -1.1 to get it to touch the paper for testing. I can't find a way to save my configuration which I thought I was supposed to do after a bed leveling. When I print it still prints over a millimeter off the bed in the air. When I go back to adjust the Z offset, it will not move, the display shows the offset changing but no movement. I have found different versions of both the mainboard .bin files and the pads .tft file. I could be using the wrong ones. So questions; What file versions should I be using? All files have been downloaded directly from Creality. I still don't know if flashing my printer is working. How can I test this? How do I look at the software version of my motherboard with the 3D Pad Mini? Lastly, why can't I switch back to my original screen? Do I need to remove my BL-Touch from the motherboard and plug it into the 3D Pad Mini? How can I complete an auto level sequence? How can I fix the Z level for printing? How can I save my configuration? Lastly, the gcode image does not show on the screen, just blank with a 0%. What else am I missing? Any help would be greatly appreciated.
