Setting ABL offsets

[Mik-S-UMS]

I think it would be helpful to have instructions on how to set ABL offsets in the release notes/firmware selector.

Several people have mentioned that probing is not right when installing Mriscoc, and most of them had the S3.
I have just found out that the ABL sensor is in a different location on the S3 than the X3 so the default offsets will be incorrect.
Apparently the S3 sensor is 20mm further forward then the X3. You can read more here.

This may also be an issue between other versions of the Aquila or if the user has made other modifications.

thanks for letting me know, ill get on it. So the X3 has the inductive sensor right? is that true for S3 as well? do you know what those offset values may be?

I've updated the release notes, added what to do near the top above Recent Updates https://github.com/classicrocker883/MRiscoCProUI/releases/tag/2.1.3f-8

How does this sound?:

If you are using an Aquila S3, use firmware having _IND (Inductive Probe). You may need to adjust your Probe Offsets, specifically the Y Offset, set this to -20 or -25 as per this post here. From the Main Menu, go to Level > Probe Settings > Probe Y Offset.

Looks good. Might be worth adding it to the firmware selector too. You could even have this appear when choosing the X3 firmware.

I always assumed it was the same between the X3 and S3 as they use the same sensor, the only real difference is the S3 is direct drive with a tool-head board, but only when someone had both models to compare that we realised the offsets for the ABL are not the same.

I'm going to hunt for that video I saw a while ago that shows hot to calculate the probe offsets properly so we can get a definite value to set here. I'll link to it in that post when I find it.

is that by printsleo3d? he had a pretty good one using a sticky note pad and marking where the nozzle hits, and where the probe hits, and just measuring the difference.

[Mik-S-UMS]

Yeah. It was not the video I was looking for but found the printsleo3d one and is a much better and simpler way of doing it. Its just a bit harder with the inductive sensor due to is size so you would have to work out where the center point of the sensor is.

[classicrocker883]

I suppose one could tape something pointy, like a needle or pen, to the side of the sensor. with it is acting like a probe, you just add the difference (radius of the square), that should give the center of the sensor.
