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.

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.

Clicking sound when purging

Kathy Hsieh — Fri, 08 May 2026 15:30:49 +0000

Hi All,

I'm having some problems with my printer. At the beginning of the print the extruder extrudes the filament smoothly but as time goes by it would extrude in short halting motions causing an uneven print with a fuzzy surface. I have tried reloading the filament as well as well as doing a cold pull. When I purge it does it in short halting motions and have a clicking sound before it purges normaly again. We've had this printer for a couple months and it was printing regulary before.

Thanks!

Kathy

Printer stand option

Phil — Fri, 08 May 2026 14:14:18 +0000

I’m looking to buy this stand for my printer. I’d like to get it with casters (all 4 casters are locking). The stand looks solid and heavy. Do you think the casters will create to much vibration?

A new configuratiion of PrusaSlicer makes a problem with "FW crash detect!" error

Slaw — Fri, 08 May 2026 14:09:07 +0000

Hi All,

I started to receive the "FW crash detected!..." error on all my three MK3S+ printers (firmware 3.14.1).
It looks like, it started to happen after the last configuration update for PrusaSlicer 2.9.4
When I start print a new .gcode file, printer beeps, restart, and after the restart the "FW crash detected!..." error appears on the printer screen.
The issue appears even for very small and simply file, like a small cube.
Old .gcode files (even big ones) generated a few months ago can be printed without issue.

I tested it on my 3 (!) MK3S+ printers with the same firmware - all the same result.
If I press the select button, the printer shows the main menu, and if I select an old .gcode file, the printer starts to print...

It looks like, all newly generated .gcode files from PrusaSlicer cause the error...
Anyone else, have similar issue ?
