Many Tina2 users reported me big troubles and damages to their hotend cables in the long term use.
And I'm pretty sure the culprit is the way they're doing Z homing.
That's why I created this new part.
Be gentle with your Tina2 and start changing your Z homing method... before it's too late!
The first mod every Tina2 user start with (including me), is to remove the child protection and to use a small printed part like this one to keep on triggering the Z endstop.
While it seems to work pretty well, I've seen many people starting to have big issues with their hotend cables and these damages can lead to quiet expensive and annoying repairs.
Here is an example of the damage on the hotend cables I'm talking about.
After investigation, I'm pretty sure that this part is the culprit.
So I started to think about it and ended up with what IMHO is a much more elegant solution.
Not only this new method resolves the cables damage problem, but it also offers a way to fine tune the Z triggering distance with an adjustable screw.
