probing... sigh

joehsmash

well clearly my probing isnt working as it should lol

ive tried every kind of tape i can get my hands on to make this ir probe work it just doesnt want to....

looking for other suggestions until my buildtak flexplate gets here...

I should specify, i have an original robo3d r1, my bed is all black glass with white writing on it.

I had one hell of a time trying to get the IR probe to work. I had a Creality glass that had little dimples and writing on it. Messed the whole thing up.

What I ended up doing was doing a level from the actual bed plate, without the glass, then zero with the glass on top afterwards.

Now I have a fully clear glass and it works really well, except when I put hairspray on the glass for adhesion, it messes the height of the zero so I have to mess with babysteps.

@Thalios i wish i could do that, my bed plate is the glass, thats how they did it on the robo.

theres magnets glued to the bottom of the glass, which hold it onto the y gantry track, and the heated pad is directly on the bottom of the glass.

perhaps i should just order a new heated pad, and do a full aluminum bed swap. i already have the aluminum plate here, both 3mm and 8mm plates.

Odd I only use IR sensors, with three on creality dimpled glass plates, they run fine.

Another two anycubic's with ultra base (again a dimpled surface) and those too work fine with IR sensors.

@CaLviNx i assume you have an original David Crocker ir probe?

Mine is a clone, that i bought off the robo3d forums

I have an original, latest version. When I probed, I would get random points that were over 1mm off from the others.

@joehsmash

Yes I didn't even know there was a cloned version

@CaLviNx i think im just going to manually level it and be done with it. Kinda drives my crazy that it has to probe every time.

The IR sensor doesn't work well on plain glass. It can work well enough for most purposes if there are no coatings on the glass and there is a Matt black surface underneath it. So if your printer uses a glass bed on top of a bed with lettering on it, put a sheet of black paper under the glass.

Black glass would probably work well, but is hard to find.
