[FR]: filament cutter (servo driven) #27

Open bsafh opened 3 hours ago

bsafh commented 3 hours ago

What feature do you want to see?

Which cutter can be used ?

To be more precise: for this direct drive extruder:

Tronxy X5SA Pro, but with the Klipper Update Kit and an direct drive extruder/hotend update kit:

for this direct drive extruder: https://www.tronxy3d.com/de/products/tronxy-3d-printer-parts-high-temperature-print-head-for-x5sa-series?variant=43828171833588 (320°C version) and this Klipper control unit https://www.tronxy3d.com/products/tronxy-klipper-firmware-upgrade-kits?variant=44680278671604

It's very tight (direct drive - not much space between extruder an hotend by design ...) and quite heavy

I also have a Tronxy X5SA (not Pro) but modified the gantry with a custom setup using linear motion instead of rollers. Unfortunately, I don’t have the same print head, so I can’t help with designing a custom mechanical cutter. However, you could try remixing this model: Small Filament Cutter.

I think there should be enough space to place the cutter between the extruder and the hotend

As a side note, I'm planning to release a second PR soon, which will include filament retraction between swaps to save filament, as well as support for a servo cutter.

I think a servo cutter might be an easier option for your printer since it would minimize the need to move the printhead, which looks a bit heavy...

you are totally right - a servo driven cutter would be the best solution

I probably won't be working too much on this feature, as the existing 3MS codebase will soon be replaced by Happy Hare (which has a beta coming out very soon supporting the 3MS). See https://github.com/3DCoded/3MS/issues/25#issuecomment-2465460884.
