oh man I hope the furnace is now working again! Stay warm!
Thanks for all the help. I’ve adjusted the gantry, but am still having issues (although a bit more manageable now. So I’m going to keep trying and troubleshoot this!

Am I reading that right, that just the last line is out by 1mm?!?
Are the carriage wheels bumping up on something stuck in the track?
Thanks, but my saga continues…
As for your saga, do you have a carpenter’s level (or anything with a straight edge)? Can you lay it on the bed and verify, visually, that the edge of the bed drops off by 1mm? That seems extreme, particularly given that cell [4,3] shows only 0.02mm but cell [5,3] shows 1.00mm.
So, either your bed was recycled from an aircraft wing
or, as @mobiobi suggests, you have something stuck on your track that’s bumping the carriage up, or, the BLTouch is being shifted.
On that last point, the Mesh Viewer image is showing the high edge on the right, but if I recall, your printer’s cables come from the left. Is it possible that something is binding the BLTouch’s cable as it moves to the extreme right and pulling the BLTouch up slightly?
So, to summarise;
Check the bed’s flatness with a level or straight-edge to visually confirm that it’s dropping off at the right. If that’s OK…
manually position the print nozzle a sheet of paper thickness from the bed - enough that you can see light below it. Then manually move the print head left and right. If there’s a mechanical problem on the X-axis, you should be able to visually confirm the nozzle lifting off the right side of the bed, which you already confirmed as reasonably flat in the step above. If the entire carriage assembly ins’t being raised when on the right-side of the bed…
pay close attention to anything that might be applying pressure to the BLTouch when it’s at the far right of the X-axis. It may not be something that pulls it up. It may be pulling it left (probably), right, forward or back. Anything, really, that causes movement in the BLTouch.
Or maybe faulty bearing in one of the wheels.
Love the flap reference:joy:
Thanks for all the ideas. If anything I’ll know a lot more about leveling the darn thing.
Will report back when I figure out more!
Victory!!!
At the very end of the X axis the rollers were pinching the BL Touch cables. I tied the harness loosely to the top frame and…
Noice!
That was a real journey…
I used the method shown here. It worked for me. I have the Ender 3 Max, which is fairly close…
But, I found that my real problem was that the Z supports weren’t parallel, causing the x gantry to get loose.
HI @era99 welcome to the Forum
I know PJ has a video listed on your YouTube about building the Ender3s.
Some nice hints and suggestions in there about building them and getting the gantry square off the hop.
I usually adjust them on the left side gantry bracket and then check all the wheels for equal contact.
It was built nice and square and over the last month’s I probably should’ve kept tightening things especially after working on the hot end a lot.
Thanks for the follow up!
anytime, just want to make sure you were taken care of.
