500mm extension - Linear rail and leadscrew

[Dcieslak94@gmail.com]

Hello Guys, 

I am going to extend Z axis in Elegoo Mars 2 Pro up to 500mm 

Do know thread pitch in z axis? 

Do you know model o linear rail which is originally mounted

I looked at 250mm extension

Do you know name of this aluminium profile? Is it something standard?

I have the 350mm extension made by Simon Jackson (he has closed shop) for the Mars 1 (upgraded to accept Mars Pro screens).
I just retired that old printer.
AFAIK the frame of my 350mm extension is the same as for the Mars 2 Pro. Just the drilled holes won't match up.

I'm investigating the parts to do the same on my own for the Saturn 3 Ultra 12K.

The linear guide rails are the same I already have in the Mars 1.

A longer ballscrew of the same type should be no problem at all.

The software is just an M8026 command (https://drucktipps3d.de/chitu-gcode-mcode-uebersicht/)

That leaves "just" sourcing or making the extruded Z casing
