Slight forward lean to my prints  

Re: Slight forward lean to my prints

Silly question, but is the end of the steel ruler definitely square? 🙂

Re: Slight forward lean to my prints

😀 yes, the ruler is square. I used an actual square to determine that the prints are leaning, but it wouldn't photograph well, so the ruler was used for the pic.

Re: Slight forward lean to my prints

It might be worth just check the wiring. I noticed a little while back that when unloading the filament the bed would move ever so slightly. It seemed to fix it when I had a wiggle of the wires.

Are you running completely standard, no igus bearings?

Re: Slight forward lean to my prints

Alternatively it could imply that the metal frame is not at right angles to the bed.
If you take the z right the way to the top, are the horizontal rods in line with the frame?
Measuring the distance between the bed and the rods, are they equal on both left and right sides?

I would have thought that PINDA auto-calibration at the start should adjust for that though - Have you used the new firmware's calibration?

Re: Slight forward lean to my prints

VortyZA has made a very good point there. It only needs to be slightly off. The auto mesh will sort so much of it out but as the lean is also very slight it could show a bigger problem on the frame angles. Certainly worth checking what VortyZA says a +1 from me on probable cause 😉

Re: Slight forward lean to my prints

The auto mesh will sort so much of it out
Wrong. This type of misaligned geometry is NOT sorted out by MBL. 😉 You simply have to assemble it right to get correct outputs.

Re: Slight forward lean to my prints

So what is the problem with the above David? You seem to be quick to tell people they are WRONG but cannot add anything constructive to help solve the problem. Maybe you could say what the problem here is?

Re: Slight forward lean to my prints

I did.
The reason is pretty obvious. If the Z frame is not perpendicular to Y frame, it has to be repaired mechanically, there is no other way, MBL will not fix that, it can't "see" such type of misalignment. If you don't believe it, just draw side view of printer geometry and think about it a little. 😉

Re: Slight forward lean to my prints

Maybe you could have thought about it Monday and not jump in after everyone else has helped the person 😉 You simply jumped in to make a person feel bad about themselves on this forum. Perhaps stick to your native language forum ey 😉

Re: Slight forward lean to my prints

I considered it necessary to correct the misinformation that you said.

Re: Slight forward lean to my prints

Please do explain? So let me try and explain it in ENGLISH so you can understand ENGLISH a little better before jumping in trying to correct someone. I will be the first to admit I am crap with languages so I keep out the way. I do not feel it necessary to start joining forums to tell someone they are wrong without fully understanding it. So let me put it in another way which you might understand a little easier.

I basically said the mesh bed leveling will only sort so much of the bed leveling level out (unless that is not what it does). I did NOT say that is the problem or it would solve the problem. You have yet again misunderstood what I have said and attempted to bully me on this forum. Sorry you decided to take that very small sentence out of my entire paragraph, then take it the wrong way! You should stop commenting like that, You do not like it when I do it which I have done only the once! 😛

Re: Slight forward lean to my prints

Back to the topic.
I have a question for Michael. You have asked about slight forward lean, but according to your image and signs on the heatbed, it looks more like left lean. Is it actual photo of object after printing or is it arranged to get a better shot? Just to be sure.

Re: Slight forward lean to my prints

Deleted. Forget it. I am sure if you had a real problem you would PM me to try and solve it! 😐

Re: Slight forward lean to my prints

Hi

I noticed a lean with one of my prints as well:

😀

Seriously, in all likelihood, the lean in this instance is caused by the Z frame not being perpendicular, which in turn, may be caused by the Z Frame being the wrong distance from the rear of the printer and the PSU, being connected to both, is pulling the Z frame out of square.

Re: Slight forward lean to my prints

Thanks everyone for the input. I'll recheck the alignment and measurements of the frame to insure that everything is square.

The photo is of a print I had already pulled off of the bed and turned to the side to get a good angle for the photo.

I'm still a little concerned about the Y pulley not looking like it is spinning on a centered axis. I'll get some adjustments done this weekend and report back.

Re: Slight forward lean to my prints

Michael

Can you get a picture of pulley on the motor?

Re: Slight forward lean to my prints

Ben

I don't think the pulley is an issue. This eccentric running is quite normal and leads to a slightly tighter belt once per rotation.

Further the pulley would be in identical position on the various perpendicular walls of a "vertical" print, irrespective of height, so it could not cause leaning.

It would be a good idea to see which direction the opposing wall is leaning.

Re: Slight forward lean to my prints

I agree it probably has nothing to do with the lean Peter but wondered if we can get a picture to see if there is a problem with the motor/pulley or not while we are helping on the thread. 2 birds, one stone sort of thing. :geek:

Re: Slight forward lean to my prints

I realised a long time ago, that one-at-a-time is a far better way to deal with things. Gets rid of any misunderstandings if we are all discussing the same thing.

The lean is what Michael is rightly concerned about, whereas a slightly eccentric pulley (which is quite usual due to manufacturing tolerances) is a secondary issue.
