Solved Height Map - Substantial z-offset after setting z-offset
-
@fcwilt Thanks mate - I'll give it a go
-
@fcwilt so I did a G32 and had to adjust the knobs again, and then ran a G29 with one probe and F100... it took a while, but mesh looks much better. We'll see how it looks tomorrow after a 20hr print.

I was a programmer for 30+ years but now given the limited number of files I put them in one place and I always know where they are - the System folder.
71 year old brains crave simplicity@fcwilt, software engineering is a relatively new profession. Did you transition from another discipline?
Software engineering is unique because people from other disciplines can easily transition to it and do well just by applying common sense. This is not the case with other branches of engineering and STEM (imagine a software engineer designing a bridge ;)).

Actually I studied digital circuit design and did that for a couple of years but when microprocessors began to take off my company needed someone to learn how to code for them.
From that I learned that I liked programming and had the skills. So I branched out into application programming.

So finished the print and ran another G29... this time it was still a good mesh and worked well. Not sure but thinking I may want to tune my stepper motors to help reduce them falling, one side or the other.

Sounds promising.

One of the benefits of auto bed leveling is getting the Z steppers back in sync.
On my 3 Z printer when removing the magnetic print surface a stepper sometimes moves due to the reduced current levels.

@fcwilt Thanks mate - I've just got BL Touches delivered and am going to put those in versus the EZABL probe.. that will be todays task.

Stumbled today upon this unboxing video. The printer has two Z motors as well as a belt that keeps them sync'ed. It's an interesting idea.

Thanks.
I've got one of the earlier, smaller Sapphire Core XY unit
It was a pretty nice unit of the box.
But I cannot help myself and had to mod it (Duet, PanelDue, better hotend, Zesty Nimble, better bed).
Happy with the unit.
Here is a quick-and-dirty video of my 3 Z Stepper Belt Drive printer showing the ability to deal with a badly out of level bed:

@fcwilt Just wanted to post a quick update... I ditched the EZABL and put new BLT's in and haven't had a problem since. Prints are coming out beautiful and I haven't had to adjust the baby steps since the first MBL/ABL.
Thanks again for all the insight and help!

I love a happy ending.
I had doubts about the EZABL when I found out it was capacitive. Before you removed it did you ever try a very slow probing speed?
