Disassembly/reassembly of x-axis  

New Member

I damaged my X-carriage and ordered a replacement part from Prusa. I thought I had seen a disassembly guide that would help me replace this part, but I think I was wrong (I see guides for fans and the hot end). Does anyone know what I need to do to remove and re-install the x-carriage.

How about reversing the assembly guide? to disassemble...

then  follow again to reassemble?

which bit has broken?

Thanks for the idea. I think I may have been unclear or I am misunderstanding your suggestion.

The mini, as shipped, had the the x and z axis attached, and assembly only requires attaching that to the y axis. My problem is within the x-axis. I've removed the hotend/heatsink portion from the x carriage. I think the next step is to de-tension the belt so that it can be removed from the x carriage. Then (I suspect) I can slide the x-carriage off of the bearings. At this point, I reverse the process (I think). I am hoping for confirmation or correction on this point (and to head of suggestions, yes i have contacted support :-).

Edit: You asked which part was broken: the x carriage (I melted it. :embarrassed:) This is the printed part of the on the back side of the hotend/heatsink/part cooling fan assembly.

Just to close the loop on this, I got a response from support. Explicit documentation on disassembly/assembly of the x-axis does not exist, but support was able to confirm my basic understanding of what I needed to do and give me a few pointers on the order of operations. I'm now back up and running.
