People wanted pictures of what i was talking about
just to have discus on possebility on what can be done later of course  its working good now but later maybe need somthing new better.
or if someone maybe already is trying to do same
and get the word out here

And what kind of gease that is best to use when we only have plastic parts on metall.  solidoodle told me to use lithium but not spray can lithium
and that grease that was original on the carriges cant be brough  it was only expensive factory grease.

Use silicone grease like they use for airsoft guns, it wont damage the plastic parts and last a considerably long time.

I am not following on what you are asking. Are you wanting to design one? Are you wanting someone else to design one for you?
I am not understanding why you want to change out stock gantry so soon. Granted yeah there are no bearings at all. But that was part of the price of admission here. Low cost = no fancy linear bearing mechanics. I not saying it can't be done. But thats a lot of work.

I can only imagine the precision is pretty dreadful so I can understand wanting to swap.

OP if you want bearings you are going to have to design your own carriages or determine if you can somehow adapt lawsy's design in hacks/mods for your press.

we can remodel the carrige so it fits bearings

the only thing we cant change is the small rod for the y motor belt gear its inside plastic in the frame

Picture? Anything can be changed

I agree with everything except 'modular and open source' part. There is nothing modular about the Press. As for the OS part. The only thing they released was the FW. Only because they had too. And most likely not because they wanted too.

By modular, I mean you can disassemble any piece and swap it out somewhat easily. There's no proprietary screws or needlessly complex design stopping this.

They used open source firmware, so of course that piece is open source. They didn't really release it themselves, but you can go to that project's source page.

As a result of the firmware being open source, the commands to control the printer are also open. You can use any compatible software you want.

The filament is also standard and there's no attempt to lock out competing filament vendors. They have a special spool for the Press, but you can use any other type with not much compromise.

I am not an expert, but if you know enough about this issue to see it's a problem, you can probably just use grease as you feel is needed, and be done with it.

Given how many issues existed out of the gate, it's a bit naive to expect any part of this printer to last long term, but it is modular and open source, so you can always fix or upgrade components as you wish.
