Is this to big?

Is this to big?

1000mm x 1000mm x 1000mm

For the sized rails you have, yes. Those need to be at least 2040 or ideally 4040.

Yes , u are right. Was My first thought too. But this Printer Will be a closen one. I will screw 2mm polycarbonat plates on the sides, too get stabilty

It’ll flex like a gymnast. Even with PC covers

Really? It will be fixed at 5 points per rail.
The polycarbonat Starts to bend at 260 degrees

Yes.
Add some Dyneema in the diagonal at the very least…

@shauki
U mean the quadrap corner spec is less flexy?

(Deutsch)
Ist das Verfahren der Verstrebungen beim quadrap weniger flexibel als wie ich es getan habe ?

@shauki , no such thing as too rigid.
