Yes, but I have removed the springs and installed solid spacers.
Printer is an Ender 6

So you can no longer adjust them?

Frederick

Correct.
I can reinstall them if I need to.

Not sure if this helps, but, I have ordered a new 1/4" thick aluminum plate that I plan on flattening and cutting to size on my CNC router, because the stock aluminum isn't true flat. It is slightly wavy.

Let me know what you think is best.
I don't have a problem putting the springs back on.
The other thought I have is to use screws with lock nuts instead of springs. This is what I have on my Prusa MK3s.

The firmware has a feature that will probe the bed and tell you how much to adjust each adjuster to get the bed level.

It's optional and it can take a number of runs to get it spot on.

A CNC router? I know what a CNC milling machine is but not a router?

I finished V1 of the files. I can email them to you if you wish or I can post them here.

Just let me know.

A CNC router is the reverse of a 3D printer.
Take away material instead of adding.
A mill is pretty much the same, only smaller and more like a drill press. Also the spindle is much slower speed.

With a router, you can make kitchen cabinets and such.

Very nice. I wish I could justify having something like that.

Got your email.

I'm looking over the files.
I think I will respond via email.

I agree. I justified it through our company. Nice to have these machines to work with.

I've added the adjusting springs back onto the printer, so I can manually adjust the bed.

I need to know where the adjustments are relative to the position X=0 Y=0.

Sometimes these adjustments are under the bed by a bit, sometimes outside the bed by a bit.

In any case the more accurate the positions you give me are, the better.

Discovered today that my filament sensor is missing.
I'll go back through my original config.g to see if I can find the settings.

Got the 1st test print completed.
I had to baby step +0.4 to get filament to come out.
This is with mesh comp. on.

Figured out why homing wasn't working.

For some reason, X needs to be homed 1st followed by Y.
So, I had to split those up in the homez.g file

I still get the "jump" when homing.
