Can you share the source? I'd like to look through your changes and merge them with mine if possible. Thanks.

I saw your video for this before the thread. Very cool.

It appears the offset between the two print heads is completely variable, based on where you snap the second magnet on the belt.
How do you protect against banging on the end stop? Or is this completely up to the user?

...But that wouldn't be true of Marlin, which you would have to re-flash every time you make an adjustment. Doing it in software seems much simpler. But I tried messing around with the extruder offsets in Simplify3D, and it didn't appear to have any effect at all. I'm never sure if I'm missing some...

As long as there is no risk of lost bearings sliding a new one on the end, why didn't you lead with this? That sounds way cheaper than ordering anything available on ebay for this project. Because I just found out. I've been spending time the last couple of days trying to work out a good set of rec...

The mounting plates in Tim's pictures are black, not silver with 30 tiny holes like my dual extruder mounting plate. I REALLY want to duplicate your results and join in the fun. But I am really surprised that magnets are working this well. I guess I shouldn't be that surprised. The carriage bearings...

Sounds like in the short term we should post process with a perl script to clean this up. Then give it to the S3D guys as a proof of concept.

I think I'd rather see this piece milled from aluminum as Makergear's versions are.
But we can wait until you've finalized the design to do that.

How about those magnets. Did you need to reduce the maximum X jerk/acceleration?

Did you print the v4 clamp plates? Won't those melt or at least deform?

I'm really excited about this. Keep the info coming.

Wow. Is it just me, or was that really fast from idea to prototype?
What did you go with for grabbing the carriage on either end? I had assume magnets wouldn't hold well enough. Did you just prove me wrong?

... I want full plans so I can modify my own now.
