PEI Protection

Newbie question ... but I haven't seen it mentioned anywhere ...

Do people protect their heatbed / PEI sheet while working on the extruder?

I'm having nightmares about an errant Allen key augering a divot in the surface.

Just a board laid over the heatbed? But then we're increasing the possibility of an extruder crash into the very thing designed to protect the heatbed ...

Re: PEI Protection

The PEI is pretty tough. You're not going to damage it by just dropping a tool or part on it.

To damage the PEI you'll need to do something like gouge it with a knife blade.

i would rather something damage the PEI sheet than the actual bed that heats up... there are traces under there and could get damaged accidentally. usually printers have glass over them. i would rather the steel sheet... it's not powder coated anyway so... no biggie if the PEI gets damaged.

And for 108.85$ I can get a new heatbed delivered to my door, in sub-1-week.

For ~840$ I can get a PEI steel sheet delivered to my door in about 1 month.

Personally. I think the heatbed is much cheaper. Although honestly, the new PEI sheet comes with a few spare parts...

Re: PEI Protection

I don't really understand this question. It's common sense to protect something valuable.
Like a table where you do your assembly or a hand/fingers while you attach or remove parts from the printer or ...

If you worry about the heat bed while working above, just place a hand towel over it.
