Vary wavy inconsistent prints
Hello everyone,
I've been 3D printing for a while but I learned through testing and not with tutorials and now I have a few problems that have come up on my MK3. My prints are pretty wavy even on very simple prints. Also the quality is pretty uneven. Some parts of the model are pretty good but others look like the nozzle heat was too high despite my lowering it. I have recently lubricated it. I also had to disassemble the head to clear a bad jam but I was very carfull to put it back carefully with a tutorial.
I think the problem might be simple but the results on line go in a million directions. Here are some pictures of the dice tray I've been trying to print:
This is the best side
The top looked okay
I was wondering if the bottom layer highht might be the problem
The outside wall printed higher than the inside wall on one side but was the invers on the other
Here are the wavy sides, they even had some bubble looking indents
Finally this side started well and went a little crazy near the end
P.S. If anybody has some good presets for prusa somem screenshots would be greatly appreciated just to make sure the slicecr isn't the problem. I've tested 4 now.
Your filament is damp enough that it is obscuring some of the symptoms - you *might* have a belt tension issue but first try again with dried filament and show us any problems that persist.
Cheerio,

Okay, so I have a food dehydrator and I've seen people dry thier spools with tht online. Would that be sufficient or do I need a method of keeping it dry while I print. Where I live it's a little humid at the moment.
With a print that size there is a good chance that, if you start dry - I too use a lightly modified food dehydrator - the filament is likely to be used up as fast as it deteriorates so you should be OK.
Cheerio,

So I'm not allowed to use my Mom's dehidratoe but this week I happen to be doing an intership with a 3D printing company so they have looked at the model in person now and have dryed the filament in an "official" dehydrator. They suggested that it might be a problem with the bed not being level but as for the humidity and tension issues they say that those should be problems over the entire model and the symptoms on my print are only on 3 sides. There are a couple problems with the bed tension idea so I guess I'll just start my next test and see how it turns out. Thanks for the help.
With properly dried filament underlying problems should be easier to diagnose.
Cheerio,

Just to give an update. I brought the printer in to my intership location and after I dismounted it I found that the nozzle was somhow chipped partly by accident. I really don't know how it happened but I'll replace it tomorrow and see what it looks like. The dryed filament, lower temperatures and higher fan speed didn't really help much. It'a a very strage cenario. I'll send a picture of the print when I have time.

Here is the first layer of the first print I posted here. It is perfect on one side but the other isn't bonding Should I level the bed. Isn't the mk3.5+ have a self leveling system? Besides that the print is going pretty well. There are a couple skipped lines on the layers but overall not noticeable as they are on the inside. The nozzle change drastically changed the quality but a few extra adjustments were necessary.

Here are those images.

This is the same print stopped right before completion: the top is shifted. Does that mean the machine was bumped or is the temperature too low so it didn't stick. I hate to pester but getting all these problems sorted out would just be great.
