Description
This mod was designed to remove Z-chain by a Z umbilical. another umbilical toolhead is required for this mod. TH umbilical is used as guide for Z
This is still a draft, use it with care and feel free to contact me for any error or omission.
There is no longer a chain above the gantry, but the toolhead umbilical remains and can be a problem for some mounts. Changing or adding cable in the umbilical can be a pity.
Keep in mind you do it only for Style ! ^^

| PTFE tube OD4mm | 8 x 16mm | |
| 6x3mm Neodym magnets | 2 | N52 is better but N35 should but fine |

| M3 Square nut | 4 | DIN562 - max thickness 1.7mm |
| Ziptie 3mm small | 2 | |
| PUG | 2 | Shorter is better, diameter depends on your wire harness, You can use ziptie or screw version, it doesn't matter |
Prepare the wire harness. The overall length depends on your printer size. To determine cable and cable sleeve length, put the gantry at the max z position and refer the sketches below.
| S-shape of the cable |
| Preparing wire harness |
| This is a example but you can add much more cable as long as total diameter does not exceed 8.5 mm |
Once harness is ready choose Pug against central part diameter
Steppers cable length is about the same as in Z chain.
All parts should be printed with Voron specifications.
! Do not change STLs orientation !
