Wasn't a fan of what I was finding online for a cable chain on the Z-axis of the MPCNC Primo. Decided to design my own and it works great. This is for the J-25.4MM Version.
Hardware needed for this:
- 8 x M3x5x4 Voron spec heatset inserts (2 in each truck clamp, 4 for the Z clamp)
- 2 x M3x6 flat socket head screws - right truck clamp
- 4 x M3x10 flat socket head screws - left truck clamp and z-chain mount to cable chain
- 2 x M3x18 socket head cap screws - Z-clamp
- R28 Internal Size 15X15mm Cable chain, comes in 1 meter sections on amazon
- 1" by 1" Aluminum L-Channel, 1/16" thick, get as long as you need. Picked this up from a local hardware store called Menards.
What you need to print to get this installed:
- truck-clamp-j-primo-dragchain-left
- truck-clamp-j-primo-dragchain-right
- z-dragchain-clamp1
Then you need to chose one of the two:
- z-dragchain-clamp2 - flat mounting point for z cable chain
- z-dragchain-clamp2-raised - raises cable chain up about 14mm
Not required but helpful templates to mark/drill holes in the aluminum J channel.
