Can you specify the size of the necessary clearance around the hotend?

What is the problem?

It appears that the hotend assembly might be allowed to collide with tall objects on the plate when printing nearby shorter ones sequentially.

Asked if there's a way to be warned of this situation in PrusaSlicer, in the Prusa forum. Doesn't seem like it on my system.

Have you tried running in safe mode?


Did running in safe mode solve the problem?

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

I'm running OctoPrint on a Raspberry Pi 4, controlling a Prusa Mini+.

I don't think that there is a plugin for OctoPrint that checks for those kind of things.
Depending on the size of the gcode file it could take a really long time to parse it on a Pi.

It's the job of the slicer to do that. I guess you should try it in a Slicer or SuperSlicer forum.
In Cura you set it up in the printer settings

and it looks like that on the virtual bed

the grey area are the needed boundaries

Thanks! I agree that PrusaSlicer should provide some affordance for this, especially since it has presets for Prusa printers and should know what the stock dimensions of its parts are.

In PrusaSlicer the setting is here:

Thanks! Those options were missing from the UI on my system because it was only set to "advanced" and not "expert," even though the "complete individual objects" control was visible. This is an essential set of parameters for that option. Secondarily, it's a good example of why you grey things out that aren't applicable, instead of just making them disappear.

That's the reason it was hidden. Most PrusaSlicer users use it for Prusa printers. :wink:

Also users: Why are those things greyed out? I can't reach them.

I am using it for a Prusa printer. So... that doesn't explain why it's hidden.

Also users: Why are those things greyed out? I can't reach them

Exactly. That's why greying out inapplicable controls has been a cross-platform standard for decades. It tells the user three important things:

  1. The option exists
  2. Where it resides
  3. Some conditions need to be satisfied to activate it

Except Cura, Simplfy 3D...

Cura does it. Here's just one post about it.
Here's another.

So does Simplify3D. Here's a post that mentions it. The first reply:

The options unavailable will be greyed-out.
