A nozzle Z probe + toolchanger for Voron 2.
- Drop in compatibe with Stealthburner hotends.
- Supports Mini Stealthburner for more compact footprint - can fit 6 hotends in 350 frame.
- Adaptable from Tap with mostly just printed parts.
- Same rigidity and probe accuracy as regular Tap.
- Mostly staying within the same external printer dimensions.
- No servos, no wires on the shuttle, recommended to use with a Canbus toolhead board for less wires, but anything goes.
- Uses the Tap sensor to verify successful dropoffs and pickups.
I would recommend to install a working single hotend printer first:
Multiple tools setup:
- You will need a umbilical system supporting multiple hotends, I am using this
- Install docks.
- Configure Klipper.
- Calibrate the offsets. I'm using this.
Improvement ideas - bugs, pull requests welcome. Find me on Voron Toolchangers Discord, or file bugs here.
See Tapchanger youtube channel.
- Basic models from Voron Stealthburner and Voron 0.
- Mini SB Orbiter cowling form mozartlovescats.
- Mini SB LGX lite cowling form MC.
It's essentially an oversized linear rail, that supports only ~4 mm of travel. The steel rail is replaced by bearing riding on rods.
In addition, it's a kinematic mount, meaning that it's self aligning and there is no play even if the parts are not aligned precisely.
Option to use square rods for better contact surface for the bearings. Shares the shuttle and bearings with rods.
There are now total of 3 versions:
- Plates - bigger bearings, more work to make the plates and assemble. The rolling surface is not great. Very rigid.
- Rods - smaller bearings, easiest to assemble, but more flex.
- Square rods - middle ground between plates and rods, the rigidity testing was done with this.
Various fixes to refine the rods version. Ready for general testing.
A new experimental version using 3mm rods. See -rods files. Shuttle and mount plates changed, the rest is same.
- Easier to assemble
- Tension adjustment screws easily available
- Runs smoother
- Using smaller 3x8x3 bearings - saves 5 grams and even more rigid.
- Even load distribution between the bearings by adjusting the angles to 26 and 64 degrees.
- Minor model tweaks for better fit and printability.
- Redesigned and optimized - not compatible with V0
- Significanly more rigid
- Supports both Mini and full size Stealthburner
- It can print and looks reasonably rigid
- ~10 Tool chnages so far
- Initial dock, that looks okay for the job
