You will want to put a surface like buildtak, Matte black PEI Or pick up some Matte black High temp oven/grill paint from the hardware store and paint the bed surface. Anything to reflective or clear will make the sensor act crazy. It would also cause the sensor to work fine one minute and be crazy the next.

Also can you post your config.g and bed.g files.

home your printer so the hot end is far away from the surface, then look at the sensor in the web interface it should read 0 or close to. If it doesn't check to make sure there is nothing stock on the LED's actually make sure they are still there. I had a part collision and it knocked them off the board. Also check your wiring if for some reason the plug is on backwards it will read triggered all the time. If it does read zero check your bed surface, matte black is the best.

Thanks, You might want to ad this to the Wiki page for setting up the Z probe.

I need to run my printer so I am going to put my WiFi board back in but I will make a bench test for it and keep trying things.

Would it be worth the time if I completely erased the board and re-flashed it via usb?

Here is my home all file. When homing they go in order Z,X,Y for my main move and for fine adjustment they go reversed.

I can ship you the board if you want.

It moves to towards the switch. But they should not be moving at all. This is why I link it is the board. With my WiFi board the printer runs perfect. If I bypass the external drivers and the encoder and run them from the main board they operate as intended. It is only when using the breakout board for external drivers.

Thank you!!!

When measuring the distance in the X/Y direction for the placement of the IR sensor, where so you measure to on the board?

You should be able to just switch them in order. I believe the file executes as written. But you might want to move that clip before trying it.

Ok so I switched back to the Ethernet and used the same SD card and verified that the firmware is the undated one and when homing the endstops do not trigger the motors to stop. I even swapped the min and max codes so the max comes first and still the same. Not sure what the deal is.

also the firmware is 1.20.1RC2

Sure give me a day or two to switch the boards around. in advance these are my config.g and home files.

It was, I know it is a board issue. I swapped to my wifi board that I was saving for a different printer and it works fine. The only thing I changed was the board, I even swapped the sdcard so it was running identical settings and firmware. I don't want a free repair I will gladly pay to have it done, but just don't know of anyone qualified to send it to.

Not sure how your printer will turn out but I have Hss57 drives and they hate fine slow movements like mesh bed leveling. They make all types of noise. I switched my 3Z Motors back to my regular nema 23s and have no issues.

Is there anywhere I can send this Ethernet board to have it repaired?

never mind I had a brain fart. Common sense would tell you to look at the coordinates on the dam marker dot and it tells you exactly where it was.

when reading the heightmap do the arrows point to the X/Y + or to X/Y -.
