Core XY triple leadscrew 30x30x45

Here is something i designed that is based on dnewman/jetguy triple leadscrew builds, im based in europe so sourcing parts was a little more expensive that thought everything cost about ~1800 eu not including shipping
2040 aluminum extrusion frame from ratrig
Running it on a mightyboard with sailfish firmware, MGN 12 rails everywhere(stainless steel from robotdigg for XY gantry, very happy with them), laser cut 5 mm alu parts.
Carl Raffle Tecto hot end and microswiss stainless steel nozzle (going to be used mostly for printing abrasive materials)

The only thing left to do is connect the silicone heater that im planning to run through an SSR (dc-dc 25A) will post more photos soon when i get that done and will upload a video of maiden print tomorrow ,will post CAD files aswell.

Here is a video finally

Very nice! Any close ups on those red carriages in the Y axis? Interested to see how you've routed the belts

Just lead screws?
No guides?

Does the bed do the hula?

*khm* look at the photos in the first post

I still can't really see anything, are there guides on the sides of the bed?

Very sorry about those bad photos, i'm going to up a full gallery, first i want to finish the whole thing 100% and upload the CAD files... In the meantime if anyone is interested i can upload the .dwg files for the laser cut plates and specify the frame dimensions respectively..

You can kind of see them in the video as well

luka, any updates? i'm attempting a similar build. What things did you have to get laser cut besides the bed mount? Laser cutting is expensive, hoping to do as little of that as possible :-\

i'm also very interested in the xy interface, as i'm still trying to figure out how that bit goes together.

Enjoy!

You feel the triple Z-axis is absolutely necessary for such a setup? If you can drop weight and go for a bowden extruder setup, is a single Z-axis not enough?

How does extruder carriage mass relate to the Z axis design?

nice. i'm a fan of the triple lead screws design concept, and it's good to see rails being used instead of rods: that gets rid of one of the problems with rods and linear bearings: a crap-shoot on whether the machine tolerances are good.
