Restrict print area on a Delta printer

General Discussion

Basic Information:

Printer Model: Self built Delta
MCU / Printerboard: Duet 2 Wifi

Hi folks,
I’m planning on adding a CPAP cooling solution on my Delta.
As the duct attachment on the back of the effector is going to be quite big, it’s going to restrict my print area in the back of the plate a bit.
Is there a way to let Klipper know that a specific part of the bed is not usable for printing so Klipper for example throws an error like “Move out of range”?
For better explaining, the back of the plate should not be a printable area:

Thanks for any input on this topic

If you run Klipper on OctoPrint, you may try this:

Else, as a workaround:

Most slicers support including images on the built plate. You may create a red area for the forbidden part.

That would be a workaround, yes.
But to make it “safe”, I want to let the firmware know aswell.

I assume, your cooling solution will collide with one of the pillars.

And if you rotate it by 30°?

Exactly.
I already thought of that, but my Delta has 5 pillars, so rotating it by 30° will also cause a collision with another pillar. Also, the tube might interfere with the effector arms.

I see, that makes it a bit more complicated…
