What are y’all doing for the wires off the z? I use add-ons for the burly that lift up a flat bar I can ziptie.

@niget2002 posted a bracket the can be used to mount 1" aluminum angle to hold of the wires. It is working pretty well on my Primo. I just need to tighten the screws so it will stop getting knocked around.

Yes, that’s what I will do if 82mm Z range is too wobly. Not sure why you deleted the post Thanks!

Thanks that looks great! And thanks to @niget2002

I used those brackets by @niget2002 and they work great. I didn’t have aluminum angle on hand but I had some 1" square dowel rod from another project and that worked really well. It’s lightweight and easy to screw stuff down with simple wood screws so it was perfect.

Here’s the Z-axis cable guide on My Primo.

Thank you kind sir!

After a flawless core print, having issue with the trucks. Same brand filament, different color and bought 1year apart.

Thin spot on the outside of the stepper mount. I feel like I could glue the first and scrape/flatten the second, but it’d be good to get an opinion from @vicious1 ? Repair or reprint?

Thanks!

I don’t think those broken parts add anything structurally. If it were me I wouldn’t even bother with repair, just remove the broken pieces and continue.

wellthad · July 19, 2020, 5:26am

I agree with Jamie I just assembled that part today and I cant imagine that being a prob.

What is the aluminum bracket sitting on?
Thanks!

wellthad · July 19, 2020, 5:27am

Also copper and purple sounds badass! i cant wait to see your build

jamiek · July 19, 2020, 5:31am

It’s David’s bracket, which I am also using.

charles · July 19, 2020, 5:59am

Thanks all!

I`m still trying to gather courage to spend 100€ more on 25.4 mm version vs 25mm version.
In meantime can you tell me if I should go with 0.083" wall (2.11mm) or 0.109"(2.77mm) wall?
Plan is to build 25"x25" or maybe smaller 25"x18" with minimal Z of 82mm.

For the Z Axis cable management I am using a Drag Chain. See https://www.thingiverse.com/thing:4541775
