Need a new and improved UM1 leadscrew

[xeno 108]

I see the UM1 heated bed upgrade uses a new leadscrew (um2 ?)

but I changed my UM1 into an UM+ with double the height.

I would like to use the new heated bed option, but for that I would need a new 60cm leadscrew from the new specs,

can anybody give me the specs and maybe a link to buy a longer version

The new lead screw is attached to the motor. As in, they're a unit, not separate pieces.

Check with Robotdigg, they have threaded rod steppers with TR8x8mm screws (I belive that is the same kind used on the new Z-axis and the UM2) up to 500mm in stock, and says that they can do custom ones: http://www.robotdigg.com/category/8/Threaded-Rod-Stepper

you're saying, they cant be separated to put a longer version on it ?

Correct, the leadscrew is a integral part of the motor and cannot be separated.

You can also use the old Z nut on the bed, with a printed connection piece. You do need to cut a piece from the alu-bed then. And adjust the steps-per-mm for the Z.

We looked at this as an option for the upgrade kit. But it added more parts for us, which made it more costly in the end.

I was hoping to share the parts of the kit, and just use the heated bed parts,

but as the leadscrew is an integral part of the hardware and software upgrade, I will have to buy the complete set and just use what I need.

And I will have to buy a second leadscrew for the height I need.

Thanks for the info guys
