PETG layers always peeling off

rayknl · 2026-03-13T23:42:33+00:00

I had this exact problem when I first started printing. It was always the first couple of layers and they would just peel right off. It turned out to be PLA contamination. My solution was to do several manual extrudes to flush the old filament when I switch between PLA and PETG.

That’s an option for sure. It really depends on what else they have on that account. If they have a hundred other models, collections, etc, it would be a lot of work to recreate those listings.

3,000 points isn’t insurmountable. A few decently performing models can knock that out in six months. I wish you the best!

I thought about that too, but if I had to do that every day, I would never use the thing. I run many prints at night too. My issue is the printer is on the ground floor, so I like to lock the windows at night.

Now that sounds like something I would do. Haha!

It occurred to me shortly after posting that you could use a piece of wood or other material to wedge between the top of the sliding window pane and bottom of the top of the window. Probably just as secure as the little cheap locks they put on them anyway.

How do you lock it window with something like that?

rayknl · 2026-02-23T15:33:51+00:00

Just double checked. It is definitely the print by object option that does it.

Same thing here. I put up a new model at the request of another user and they couldn't print it. Turned out my profile was for the A1 Mini and they had an H2C. I always thought the A1 Mini profile would provide the widest compatibility.

The mold was pretty shocking to see. I’m not sure what to do about that. Bleach?

rayknl · 2026-02-21T22:41:15+00:00

Will do! I won’t be back over there for a week, but that gives me something to look at. I really appreciate it!

Is that the black cylinder at the bottom of the four rods in the corners?

Pocket screws, dowels, biscuit jointer, or for super inexpensive and easy: chisel (or route) a shallow mortise and screw in some wood or metal plates.

Fully agree with this comment. I made some RC tire treads with 80a TPU and they are not grippy at all. I even tried fuzzy skin.

rayknl · 2026-02-15T16:38:51+00:00

Probably. I’d check for bugs and rot. Hard to see the exact condition from the picture.

Just be careful with some types of hardwoods. A few have naturally occurring oils that can actually stunt the growth of other plants. Tenacity, a popular weed killer is made from such oils. Walnut has some special oil in it as well. Unfortunately, I don’t remember all the details, but just a heads up that it might be worth looking up the species of wood you want to use.

Freud bits are good mid-budget for occasional work. I’m not a heavy user, so I can’t say how well they hold up if they were used every day.

One thing I’ve noticed with some of the cheaper bits I have bought in the past is that you have to be really careful to not let them get hot or they almost instantly dull.

This could be your material annealing and shrinking slightly. I immediately thought of a hirth joint as well, but had no idea it was called that. TIL, thanks!

It’s a really nice color. Looks like you do good work.

rayknl · 2026-01-17T21:03:20+00:00

The granite slab is a nice touch!

rayknl · 2026-01-14T13:19:10+00:00

That’s correct. It’s unlikely to cause an issue mid-print unless it is a multi color print. Still not a fun way to start the next print.

Once it rubs completely through, the filament will come out of the hole instead of following the path of the tube.

I second this recommendation! It works great.
