Scanning Probe Mounting Issue
-
So I am reading that the probe should be 1-2mm above the nozzle. That's fine, but how is one expected to use screws to mount the scanning probe as the screw heads will protrude down below the nozzle and smash into the print. Can I please get some clarification on this as to how high I can mount the scanning probe above the nozzle?
2mm is definitely not going to work, even with low profile screws.
"The bottom of the SZP coil should be around 1 to 2mm above the tip of the nozzle, so that when scanning the bed the G31 trigger height can be set to around 2mm to avoid the nozzle contacting the bed, while keeping the coil fairly close to the bed."

@br7408 BHCS screws have head height of 1.65mm at M3, so juust within the envelope. I'd be uncomfortable with that little clearance for a permanently mounted probe though. You might get even less overhead using countersunk screws ...

@br7408 I used slightly undersized countersunk screws. Its not ideal but it does the job. IMO this was an oversight on the board design. Some PEM inserts could potentially solve it going forward. You could even try using some of their press in inserts if you wanted to give it a try yourself.

I asked someone else who runs the SZP and they went for 3-4mm distance to the bed at which the probe still worked but had less sensitivity to bed heat.

Thanks guys. Undersized countersink screws were my best idea as well. I guess I will go that route. I can probably CAD in a slightly raised index to better stabilize the board and give the screws a little more surface bite at the screw head. I will just back-load the heat inserts.

@br7408 I used normal size countersunk screws and 2 to 3mm above the existing touch probe.
