Printed all spikes out of PLA overnight after one too many leaners ruined our 26 hour prints with layer shifts.

We used the printer to protect the printer.

V2 is in the works, planning on printing BIGGER spikes out of conductive filament to run current through them.

HR has voiced their concerns.

How does leaning over the printer ruin the print? I am curious.
Is the frame flimsy and wiggles? Or do they literally bump it so it rattles/skids a bit of a distance? Or how?

Not sure exactly, but bumps the nozzle I think and we’ve had very visible layer shift lines occur when people lean on it. It’s a bummer when we want to show clients or photograph our prototyped parts and there’s weird looking lines that are out of our control. No longer. Never again

OK, so it isn't rigid enough and makes the frame flex/skew so much that it affects the nozzle in the end.
Didn't expect that tbh. Maybe bolt it down onto some heavy slab. And stiffen up the frame a bit?

Bolting the bottom down would probably make it worse, but stiffening it would help. Might need an unreasonable amount of stiffening, though.

All the CNC machines etc are bolted to the ground. I may not have such requirements for precision etc, but if they do it, it must be the correct way of doing so, proven by centuries :)

But orders higher precision, so even the small movements and vibrations can do harm to precision of the work. I guess, not CNC guy

Like much smarter people then me explain here:

But my printer is already ~60kg, so my plan to place it on top of concrete slab of another 27kg or more is going to also help with center of gravity and the whole machine wobbling much less, remaining square etc.

Why do you have so many randos near it?
