Connection to Voron doesn't work

Sebastian — Tue, 05 May 2026 07:30:04 +0000

Hello I tried to connect the EasyPrint Webversion to my Voron. But when I'm entering the Ip adress of the printer I only get: Connection error.

The Firefox app I also in chrome and with and without API key. Is there any trick? Or does this not work?

Sorry the screnshot is in german.

Need some help with toroubleshooting

Prusa i3mk3 is giving me a thermal runaway error and it has melted the heat shroud twice already. I have replaced 2 thermistors already and I still get the same issues after doing 5 to 10 prints. Here are some pictures of what's going on and I dont know what else to do. So I have tried running the paid calibration , and it fails immediately since thermal runaway. I am using overture p p l a default settings in prusa slicer version 2.9.5. It has been frightening fine for the last 3 to 4 months.And this just started happening about a month ago.

Just got a core 1+ and have done several files and some of the demos that came with it. it seems that the files that came with the machine were sliced with very high speeds set which the machine seemed to handle but I don't see any of there fast setting files that the demos had. are there a set of preset settings that are available to take advantage of the machines speed. TIA.

Quick disconnect mounting plate

I bought a used Mk4s and enclosure and it didn’t come with the mounting plate where the quick disconnect attaches. I am gathering the pieces I need to move the psu to the outside of the enclosure. I can’t find it one the site. I don’t see where anyone made a printable version. Am I missing it somewhere on the site?

Did print fan speeds for PETG change?

JPWhitestar — Mon, 04 May 2026 19:20:14 +0000

I've been running the given SUNLU PETG filament configuration for weeks with no problem. I just did a PRUSA configuration update and now the print fan doesn't want to run correctly starting with the 4th layer. The fan looks like it starts to try to spin in fits and starts but then just shuts down. The print fan speed settings are 20% min and 40% max.

Fan check passes all its tests. Is it possible I have a fan going bad and it just doesn't want to run at 20%?

Bowden tube catches on nut on vent causing it to open and close head moves

rwb43 — Mon, 04 May 2026 17:23:25 +0000

One my core one+ the bowden tube catches on the nut on the vent slider as the head moves back and forth. So the vent will auto open but the tube will catch the nut and close it as the head moves to the right. Any documented fixes for this problem?

Probleme beim Druck eines Herzchens mit umlaufend abgerundeter Kontur ....

derManni — Mon, 04 May 2026 12:49:44 +0000

Hallo,
ich möchte ein "Miss Allie"-Herz drucken. Das Herz ist 9mm stark und hat eine umlaufende 3mm Abrundung.
Mein mögliches Problem ist nun, dass beim Druck durch die Rundung ja die "Kontur" zunächst quasi in der "Luft hängt"...
Ich hoffe ich ich habe mich verständlich ausgedrückt?
Das offensichtliche Problem ist nun, dass am Anfang der Druck "in höheren Schichten" quasi nicht der eigentlichen Kontur folgt und quasi
eine Art "Abkürzung" ( siehe Foto) nimmt. Das passiert bei einigen Durchgängen. Später ist das wieder OK.
Durch diese "Abkürzungen" entstehen nun an der Außenkannte eben unschöne Fehlstellen, aber eben auch nur
im Bereich der Herzspitze. An den Bögen oben am Herz ist das OK....? Ist das ein Problem der Geschwindigkeit?
Diese habe ich schon reduziert...?
Was könnte die Ursache sein? Was wäre die Abhilfe.....?

Viele Grüße
Manni
