I ordered a new BL Touch, installed it and now works perfectly. Looks like it was defective all along.

Thanks everyone for your input!
I think I got it.
I removed the Z-Probe pin, and it now works completely.

@jay_s_uk OK, Thanks
Thanks for your help Jay_s_uk

@jay_s_uk Oh wow, I looked but did not see, thanks.

@fcwilt I am able to trigger the probe with M401 and M402

@fcwilt yes BL Touch brand

@fcwilt will try in the morning, thanks for your help

Yes Black and Brown connected to the same pin

@phaedrux I did go through that but couldn't get past this part. I think I am going to wait and see if a new probe works. Thanks for all your help, I will let you know if new probe make a difference.

@fcwilt That is for sure

@oliof OK Thanks

@oliof That worked! One more thing, it will take the probe to the middle of the bed and then go to the 1st probing point, do you have any idea why?

I have 3 Z motors and I am using a Euclid Probe that must be picked up before probing bed. When I run G32, the probe will be picked up and returned between each of the three probing locations. Don't know enough to determine why?

@deckingman I think you may be right. I was hopping for some voodoo, that I didn't know about. Thanks

@jay_s_uk Ok I will check that out, my bed is 680x680 and I was afraid if I used 3 points I would get to much sag in back corners. Also the bed is 10mm thick and is pretty heavy, so 4 motors handle the weight pretty good. I would also like to make even larger and proving out the 4 motors first.

I am using a setup like the Rat Rig, where there are steel balls attached to the bed that are sitting on parallel bars. The steel balls can slide to accommodate any movement needed to sit level. Gravity and a small magnet is all that holds the bed ball on the parallel bars. This system works great and I am getting good first layers when I use a dial indicator to level the bed prior to running G32. Then of course G29 to build a mesh.

The problem I am having, is when running G32, the bed will try to compensate by lower one of the screws to low, this makes to ball in that corner no longer touch the parallel bars. Trying to by running G32 again only make the problem worse. Are there any kind of a solution for this issue?

I have 3 motors on my Z and two of them have 20 to 1 gearing and the third has 100 to 1 planetary gearing this is because the entire gantry moves in Z. The third motor would drift down when the power was turned off. The easiest way to fix this was to use a higher gear ratio.
Is it possible to have different gear ratios or steps per mm for each Z motor?

@dc42 said in Thermistor Temperatur od T2 and T3 are not correct:

R2200

Same problem, Same Fix

@jay_s_uk Oh wow, I looked but did not see, thanks.
