I have a Langmuir crossfire pro that I’ve been working with for a while and it’s been mostly trouble free. I have been troubleshooting why the torch wouldn’t fire and realized the Z-axis cradle is broken in half which I assume means it’s not allowing an electrical connection. Can I buy another one of these?
can you post a pic of what you are talking about? the torch is fired by the relay inside the control box and shouldn’t be affected by the z axis assembly itself.
Here’s a breakdown of a Z axis assembly (be mindful of any differences, this setup has been found in the years of 2021 through 2024)
In this particular one, a small tab on mine was broken but maybe it’ll help with picturing the whole setup.
Really simple design overall, but just sharing additional pictures so I don’t give you an incorrect reference for the broken part on my old setup.
Thank you! That’s helpful. I need to disassemble it and see if I can just weld it?
I’m not understanding what part broke exactly?
The plastic? Langmuir will sell you one as they sent me one for mine.
The only metal parts are the steel rods, the aluminum mounting plate (black), and the aluminum assembly (black). The “contacts” for the IHS switch are two small copper plates. The black item riding up and down the leadscrew is a leadnut and that is also plastic.
From the first photo that looks like exactly the same part that broke on yours

Ahh gotcha; my eyes were playing tricks on me and I sort of assumed that until he asked about welding it back together 
There’s a member on here that sells an upgraded replacement, forget his username.

In a pinch I’m sure that plastic part could be printed out temporarily.
It also looks like his bottom contact is loose and weirdly off to one side. It’s sitting at 45° instead of right on top of that other piece of plastic

Didn’t realize it was plastic! That’s not ideal
