Changing Belts on CoreONE

HappyKatz — Fri, 29 May 2026 00:45:44 +0000

My oldest C1 is now in the position where the belts are showing wear, and I can see small deviations in the first layer of my print. This has been running for close to 600 hours, so I imagine that this is the expected life span. Has anyone else managed to wear out a set of belts yet ?

Nozzle Identification

Kapwinnnng — Thu, 28 May 2026 21:49:02 +0000

So, I've mixed up some nozzles and I need some help identifying them.

How do I tell a regular brass .4mm nozzle from a CHT nozzle from a high flow nozzle? I'm missing some of the nozzle holders that they came in and these are just loose.

I tried to look the numbers up on the store, but I haven't been able to find the actual numbers that match what is marked on the actual nozzle.

Thanks for the help!

Inquiry: Print Sheet

ENGLISH:

I bought the MK3S printer on November 23, 2023, and I’ve been using the PEI sheet ever since.

But even though I calibrate the Z-axis correctly, I’m having trouble getting the objects I print to stick.

Yesterday I bought another PEI sheet from a guy: “Adhesive sheet for heated bed from fysetc.com.”

He told me to clean the heated bed and stick the sheet there, but when I bought the printer, I also bought another textured sheet.

Can I keep using it if I put the PEI sheet on top?

Can I use other sheets, like tempered glass ones?

Should I just throw the PEI sheet away?

Can anyone help me?

You can't remove the sticker from the official PEI sheet, or if you can, I don't know how to do it.

I’ve thought about throwing away the original PEI sheet, buying a new PEI sheet, and sticking the stick sheet on top of that.

I’m hoping for a reply.

Thanks.

SPANISH:

Compré la impresora MK3S el 23 de noviembre de 2023 y llevo usando la lámina de PEI desde entonces.

Pero, aunque realizo la calibración del eje Z correctamente, tengo problemas para que los objetos que imprimo se adhieran.

Ayer le compré otra lámina PEI a un chico: «Lámina adhesiva para cama caliente de fysetc.com».

Me dijo que limpiara la cama caliente y pegara allí la lámina, pero cuando compré la impresora, también compré otra lámina texturizada.

¿Puedo seguir usándola si pongo la lámina PEI encima?

La lamina PEI oficial no se le puede quitar el stick, o si se puede no se como se hace.

¿Puedo usar otras láminas, como las de vidrio templado?

La lamina PEI , es mejor que la tire a un contenedor?

¿Alguien me puede ayudar?

He pensado tirar la lamina PEI original comprar una lamina PEI y pegar el stick encima.

Espero una respuesta

Gracias.

MK4S WiFi connection on new network

BillS — Thu, 28 May 2026 20:09:06 +0000

I moved to a new house with a new network. I was able to setup the printer to recognize the new network and get a good strong WiFi symbol on the printer. In PrusaSlicer the "G" shows up in the lower left after slicing a model. When I click on the "G" I get an error message "Failed to upload, no suitable storage at nnn.nnn.n.nnn" this address number does not match any of the address numbers on the printer.

Any suggestions?
