@T3P3Tony Thanks, I got this working. No new board!!!

Hey all,

I am having an issue with my duet 2 board and I believe that the zprobe.in pins are no longer working and because of that I obviously am unable to home my printer, or really use it for that matter.

I am wondering if I am able to use any other pins to configure my BlTouch so I don't have to buy a new board?
If so, what would that look like in the config file?

I also have a duex5 expansion board if that helps anything.

Thanks

@gloomyandy Yes, that actually seemed to be the problem for the calibration factors not equaling the number of leadscrews. Things seem to be working fine now.

Thanks to all who have given advice on this, it is much appreciated.

@Phaedrux I get the error that calibration factors are not equal to the number of leadscrews

One other thing I just noticed is that I get this error just by homing all. Maybe the issue lies there.

Here is my homeall.g file.

@fcwilt Couple questions with this.

What makes you think the order could be wrong? Not trying to challenge what you are saying, I just don't see what you are seeing to come to that conclusion, some clarity on that would be welcomed.

In my config file, I have that specific z screw being listed third, but in the bed.g file, it is set to be the second probe of the three to be probed. Do the screws need to be probed in the same order in bed.g as they are listed in the config.g?

Essentially, how it is set up now, I probe 1,2 then 3,(see below) but the order in the config file would say to probe 1,3, then 2. Is this an issue?

Also, I have since changed the bed.g probing locations to a more exact number, the original ones were rough estimates taken with a tape measure. Do the Z screw locations and the probing locations need to be the same? My initial thought is that they do not need to be, as it is the actual location, but specific coordinates to probe for those stated screws, but I could be wrong.

My setup for Z screws is laid out as such

(0,0) Home                                     2 screw


1 screw


                                                 3 screw```

@gloomyandy I will take that into account next time I run into this issue (hopefully never but you never know).

Somehow it worked fine enough to be able to change my calibration settings back to where they were before, so I am happy for now about that

undefined

@fcwilt @fcwilt Excellent catch on that typo, I completely missed that. Unfortunately after changing it, the issue still persists

undefined

@BDPrinters I have verified that the order of the leadscrew locations are correct. I got a second set of eyes hoping I overlooked this and made a mistake, but that isn't the issue unfortunately.

Any other ideas?

Thanks
Tom

@dc42 I double checked the bed.g file for hidden characters but I do not see anything other than the text that is shown. I will recheck the order of the screw locations. Does a mismatched order typically lead to this error triggering after the first point is probed but before the second?

undefined

@gloomyandy I believe they do, I checked them a few times but I will verify. I did want to allow 50mm of adjustment, the bed had quite a bit of deviation (40mm roughly), and I wanted to correct it as much as i could without unplugging the motors and manually turning the z screws

Hello,

I am having an issue setting up a new printer for auto calibration with 3 independent Z screws.

I think I have it set up properly, but I am getting errors which make me question this.

When probing 3 points using G32, the points get probed (am using a laser sensor, not a BlTouch) but I receive this error in the console, even before all points are finished probing

Error: Number of calibration factors (0) not equal to number of leadscrews (3)

I have been able to make the printer calibrate each motor individually, but one motor always overshoots the calibration, making the bed noticeably not level to the gantry. This could be a different issue but I am not sure at the moment.
