The new string-spring plan looks like a good one!
Is the change due to some problem with the magnet plan, or is it more to simplify the design? I haven't quite finished my printer yet, so haven't had a chance to explore the limitations of the magnets.
Also, I see what you've done with the spring-loaded hotend--placing a cross bar to get both springs on there. I've been struggling with a good implementation for mine, and this new idea looks like a good one. Thanks!
Oh, and I like the coffee cup, too. :)
It was actually a bit of both. I've had issues getting a regular supply of 10mm magnets that weren't horrendously expensive. The low quality magnets haven't been quite as strong that has led to a couple of times when the rods have let go when homing (never during a print though) I slowed the homing speed a bit and that cured it but I felt there must be a better way. This way is definitely better, and cheaper and easier to manufacture. Win, win, win :-)
The cup was from my niece. Very bright girl !!!
