#Hard Layer Shift

So I’ve been messing with this printer for a little while now. Took some time off the last few months as I have a million hobbies, but revisiting it as it is now collecting dust. Bought this Voron unfinished, previous owner lost interest, had no firmware or anything. Went through got that all situated, and made a couple prints, test cubes, etc. all printed okay. Didn’t really mess with much else. Began printing the parts for the enclosure, the base, etc.

Now it has a huge layer shift, I’m estimating at this time as I don’t have filament at the moment but it’s on the way, but let’s say 15 or so layer it shifts hard back and left. Every print.

Can someone tell me their thoughts, or maybe what to look at, all things considered, I suspected multiple things such as belt tension which is does it no matter what tension is on it, possibly firmware, possibly slicer, maybe even possibly the stepper motors. I’m just lost trying to diagnose it to pin point. Attached photo of the unit.

Adding this. It’s doesn’t seem to move that freely when the motors are off. When I try to push the print head from the front to the rear of the printer as long as I’m holding onto the print head it stays in the center, if I push straight back without holding the print head the head wants to move back and to the right.

If I try to move the print head with my hand left to right the gantry wants to move from front to back and it’s not easily moveable left to right

Did you heatsoak and derack the gantry? If its consistent, it sounds like binding to me.

#

When you fiddle with moving the gantry manually, you shouldn't need more than a finger.

#

What stage of half built did you get it?

So I posted above that it is binding I guess. Definitely takes more than a finger to move. I bought it assembled, lacking z end stop, and firmware.

#

I did heat soak in my initial setup, and before I print. What is derack gantry?

But of course, you probably want to measure your diagonals first.

#

just to reiterate whats in the video, you should probably disconnect your steppers while doing this so you dont destroy your boards

Ok

#

I’ll check it tonight

#

so anyway, I did my first gantry deracking today, and saw the behavior you spoke of, to a minor extent (before I belted everything).

Actually I found this whoopsie from the feller that assembled it. What do you see wrong here? This was cover because the rear panel was on.

# jagged sand did that solve it?

so far so good. waiting on filament, but i did reroute the belt correctly and while i was doing that i went through the deracking. should have filament tomorrow.
