So I’ve had my printer for a while and leveling always seemed to be a hassle for no reason. It’s a cr 10s pro v2. I’ve done everything from turning auto level off and adjusting the knobs while the hotend and bed are hot and using the metal feeler they give you as well as a piece of paper. When I go to measuring after my numbers are always quite far from each other and not very close to 0 as they should. I’ve adjusted baby z step so much it’s getting on my nerves and there’s no reason it should be such a problem

When the 4 corners seem “leveled” the center is always way too low and I can’t even get paper underneath it. If I raise the corners any higher they won’t have any resistance and wouldn’t give me a good squish

This is my process:

Make sure your gantry is even on both sides with the printer.

Hit “levelling”. Once the initial probe in the center is complete lower you z height using feeler gauge. Hit the home button so save the setting.

Then aux level. Front left, back right, front right, back left. Repeat 3-4 times until happy. Check middle again.

Run measuring.

#

I also use this video to adjust my baby z steps while increasing the three flow rates he mentions and using the single test square in the center. Utilizing a brim with .1 gap gives you a good indication of your “squish”

#

Those “measuring” numbers don’t have to be perfect, just close. Your BL touch should compensate a bit

#

Another issue I experienced quite a bit when I first got my machine was I would square the gantry to the frame, level the printer. Then after a few prints that gantry would sag on the left side. I’ve sorted it out though so if you have that issue let me know

Thank you, I have noticed my gantry isn’t completely leveled

#

I did adjust it a bit earlier by twisting the lead screw coupling and holding the left in place but I’m not sure how much that “fixes” it

I fully removed my Z rods and confirmed they were straight by rolling them on my counter. Then adjusted the block on the top of printer where the rods slide into so it’s resting perfectly straight on the stepper motor. Replaced the nuts for anti backlash nuts and installed a Z sync belt at the top. There is also a red bracket that bolts the gantry to the frame, that can be loosened and allow a little play to lower the right side if needed.

The Z sync belt helped me the most with keeping that in line

#

And use white lithium grease on the rods

#

I don’t need anti backlash I got pom to work fine

#

I won’t grease them as well due to pom being plastic so no need for grease on that, but I will consider the z sync belt if my axis turns out to be unaligned again

I’m not sure what you mean by pom

#

But hopefully I gave you something to help out

jolly tiger
#

Pom is the plastic material they used to make the nuts

#

But you certainly did, thank you
