whats the printer? the distance between both the rods looks huge and way greater then my printer

Have you running your second Titan already? Would be nice to see some photos of the final assembly. I don't want to order a second Titan while not knowing how it will fit ;)
Sadly there's no time to design my own carriage at the moment so I'd love to use this one.

I have the second Titan mounted with the stepper but I don't have a proper hotend at the moment. Need to buy a second e3d 1.75mm direct drive... I have an old Chinese clone, but I wanna wait cause that things jams occasionally and is super frustrating. So for now I've been running just the single.

Any chance you could modify this design to accept 10mm bearings? :D

Should be able to, what is the O.D. of the 10mm smooth rod bearings?

OD - 19.05 - Igus Drylin RJMP-01-10
Length - 29mm


Nice design, any plans to add a bed level sensor such as a BLTouch or Inductive sensor? Thanks

@salarellajr No plans for auto bed levelling on this machine at the moment. It's usually level it once and that's until i change nozzles or make some other significant change. Then when I do have to level, five min max and I'm done. I built a rostock delta at work and that thing could use some auto bed levelling as I find myself constantly fiddling with ends top offsets :(

Thanks for the reply, does your design allow for any Z adjustment of the nozzles so they are perfectly level? Thanks

I slotted the nema motor holes to allow 6mm vertical adjustment, idea being you loosen both motors and let the nozzles sit directly on the bed. Tighten mounts and now they should be level relative to each other, assuming your bed was already level.

Do you have an openscad file for this?

@DV7 I do not, but i can provide any type of file solidworks will allow me to export, if that helps...

I've found that scad files made by other software make everything into polygons, which makes sense. That makes it means I might as well code/draw it myself in openscad. I like your design and will use it as inspiration. Thanks for the response!

@DV7 Thank you for checking out one of my designs! Appreciate any feedback you have. Just got this new x-z carriage setup on my printer today, took about 3 hours to retrofit the old one. But so far its much smoother. Will be uploading, updated files momentarily as I made a few design changes from the first revision.
