How to create a flat solid surface on the underside of supported material

jens — Sat, 09 May 2026 06:15:22 +0000

I have a PLA print that has a large horizontal surface that needs support. I have set up for a single interface layer which is PETG. I am expecting the support to be printed with the support extruder followed by the separation layer from it's extruder followed by the material that is being supported. What PrusaSlicer does is it generates another layer called 'overhang perimeter' which is a layer with tiny gaps between the individual strands of filament. It is not a nice, smooth, solid layer.

How can I change the density of that layer to eliminate the tiny gaps between strands of filaments? Alternatively, is there a setting to not generate that layer or is there a way to print that layer with the separation layer extruder so it can be peeled away?

Accelerometer Wiring and Mount Questions

Hooovahh — Sat, 09 May 2026 00:03:27 +0000

I upgraded my MK3 to have a Bondtech BMG extruder years ago. I recently upgraded to the MK3.5. Because I don't have a standard extruder I bought the accelerometer kit to do Input Shaping calibration. I was hoping I could make the wiring semi permanent. The 3.9 and 4.0 have the connector on the xBuddy unused. So the kit comes with a jumper wire to go from the board to the wifi board. So that you can then easily plug in or unplug the accelerometer from the outside of the printer. I see that the 3.5 actually uses this port for the Print Fan. So you have the open it up, disconnect this cable, plug in the accelerometer cable, then reverse this afterwards. The Print Fan is only two wires. Is this just power and ground? And if so can I splice in these two wires into the jumper cable, so my 3.5 can be closed up and the external port by the wifi can be used?

Shouldn't EasyPrint be AGPL?

Please, could anyone from Prusa answer this?

Since Easyprint used Prusaslicer on the backend, shouldn't it be licensed as AGPL? Isn't this explicitly one of the differences between AGPL and GPL, that it enforces the copyleft in cases similar to this?

12 Animal paperclips - only want to print 10

eager — Fri, 08 May 2026 18:57:33 +0000

My apologies for this follow up post but when I load the Paperclips Collection- Trombone (with many animal paperclips) I found on Thingiverse as an stl and then place the cursor over one of the animal paperclips I do not want and Hold down the Ctrl key it highlights all the prints. I can't seem to get it to highlight just 1 paperclip to delete at a time. I so appreciate your help in diagnosing what I'm missing and how to correct it. I can't recall if I can attach the stl file here? - https://www.thingiverse.com/thing:1372960. Thank you.

XY Axis Test Failure

Sswing088 — Fri, 08 May 2026 17:47:27 +0000

Looking for a fix or workaround to the XY Axis test failure. I have downgraded firmware that didn't work. Redid the current firmware and that didn't work either. X calibrates just fine, the Y just won't. Any help on this is greatly appreciated.

Install Manual

Can anyone direct me to the manual for the install/ upgrade of the CoreOne to INDX. If it's out there I can't find the durn thing.

Apologies

Side filament sensor not connected, check wiring.

Gizmotoy — Fri, 08 May 2026 17:07:38 +0000

I noticed that the filament sensors on my Core One+ stopped working. It seems like neither one is currently functional, but they just silently failed. However, if I go into settings and toggle them off, then back on, I get a message that says "Side filament sensor not connected, check wiring." This seems clear, but I don't see anything obviously wrong, and the printer has not undergone any recent changes. Is there a service guide or something for how to check this more thoroughly?

où trouver les commandes GCode spécifiques a prusaslicer

Laurross — Fri, 08 May 2026 16:37:28 +0000

Bonjour, d'abord un point qui le chagrine: je n'arrive pas à basculer sur le forum français à partir du menu général du forum🤔( bloqué sur le forum anglais)

Bref, ce n'est pas mon sujet actuel, je cherche sans trouver la liste des commandes du gcode et particulièrement celles qui sont spécifiques au logiciel prusaslicer (codes G et M😉), mais je voudrais aussi un condensé des commandes gcodes pour l'impression3d

( J'ai un général pour les CN)

Si vous avez des pistes, merci d'avance.
