here you go A360
there's actually a reference model within the design I don't know it that will show up if I share this link. in any case let me know if it doesn't look right...

 

Yes I tested the 2nd toolhead homing routine video here

 

Just so hapoened I did have an update
So I aligned and calibrated both toolhead offsets last night. I should add a write up on the calibration process. In short it involved shining down light through empty nozzle. Then I started print but had to stop due to oozing. But hey it works!

 

Gahhh soo close. it appear my Y belt has gotten loose...

 

Yub both toolhead on. Left is doing grey and right is doing white.

 

I'm really flattered that this project inspired other to build one. I have not published the fusion 360 file yet. Yes I have been able to print quite well actually but with single extruder only. the second extruder it works but here's what I discovered:
- the magnet holding the extruder is a very good concept when I started but it does wiggle slightly in y direction mostly. so when doing overhang if the print knocks the head hard enough the head will deviate slightly. to solve this I intend to add set screw with heat-set threaded insert method. this will secured the toolhead.
- when printing dual extrusion, the park toolhead leaks a bit. I though about BCN3D where you have purge bucket but I'm trying other solution which hopefully will be better system. I needed a mechanism where when toolhead is parked, some type of high temperature resistant material is automatically raised to plug the nozzle thereby maintaining the pressure. this would eliminate the need for ooze shield and prime tower so saving in filament. this prime tower is ridiculously wasteful

there are other minor thing to modify as well but those above has been keeping me busy

I'm hoping that the combination of 300mm/s travel speed with nozzle plug will solve the need for ooze shield. Prime tower is easy to eliminate

 

The changes I plan to make should also be applied to both extruder for consistancy sake but otherwise left extruder lone printing as of now has been flawless.

 

I found this threaded insert from mcmaster should make wiggle go away. testing it soon

 

perhaps this 3D views below will help. annotation 1 and 2 are newly added. untested but I think should work

the magnet's primary function has changed or should I say... evolved a bit. Though it has excellent holding force and has no issue at all of being detached completely from nozzle knocking things around while printing, I notice when this condition occurred, the nozzle will have slight variation in Y direction.

so yes with added M2 screw, the hotend won't be easily swappable but the two magnets will still play their role in holding the top portion and as a guide for the hotend to find its seat when swapped. The M2 screw should keep Z aligned pretty darn perfect

 

hey all I'm testing sharing iges file through sketchfab. please see this one and check if you can download the file. I like sketchfab that you can check up the model up close and navigate around the model. they can also do VR if you are into those thing

Ok one note about Sketchfab... try avoid opening it at work... some of the suggested model might appear on the side bar and might not be appropriate for work environment... I have brought up this issue to Sketchfab and I think they just shrug it off...

I'm also looking for a way to embed the 3D viewer here in the actual post so no need to jump off to their site

 

unfortunately there's no easy way to include a blow up animation in sketchfab that would be awesome though.... It is possible but it involve multiple file extension conversion...
