I added functionality to orcaslicer that lets you add custom gcode with modifiers. Super useful for foaming TPU so you can modify the stiffness mid print!

Title basically says it all. I needed variable stiffness for a project I was working on, I grabbed a roll of siraya tech tpu air thinking this was already a feature that existed. Turns out its not, and instead of redesigning the part I just made the feature.

Give the video a watch for a demo (and maybe help get the feature a bit more visibility), feature branch can be found here: https://github.com/MethodicalMaker/OrcaSlicer/tree/gcode_everywhere

Let me know if you also wanted this feature at some point, or if you have any other ideas of how you can use custom gcode in the x/y plane in a functional way!

Excellent! Now if you could only make the Prusa XL play well with TPU, I’d be in business!

Thank you for your contribution! Hopefully upstream will accept it into main!

I assumed the xl would work well since its an idex, what's the issue with it? On my mmu2 I just disconnect the tube going to the extruder and load the tpu into it. I set my printer to use a filament slot that doesn't have any filament loaded, and then use an offcut to trick the mmu into thinking its fed filament. Works well enough, but doesn't work for mixing tpu with other materials. I gave up on that long ago lol

Well unfortunately the XL is not an IDEX, just a toolchanger. It’d be cool if it were both though.

My workplace got one, and it’s just not performing like a $5k machine should. I’ve built a Voron 2.4R2 from scratch that was way more enjoyable to build than the assembled machine we received from Prusa. They clearly did not test every toolhead they sent and Printed Solid sent the wrong replacement parts. I’m still waiting on the correct parts.

So despite having it for a couple of weeks, it has still not passed our own checks, and I haven’t put the enclosure on it yet, so that’s even more testing needed after that.

TPU keeps jamming on it, and I haven’t found the sweet spot for tension on the extruder gears. Most people recommend not feeding TPU through the runout sensor or using the filament holder on the side of the machine.

Since it is not my personal machine and since it needs to work for professional projects, I have less patience for these issues than I would otherwise. Especially as the market has several other toolchanger options now for far less money.
