This is still a proof of concept and an early prototype (work in progress).

But I will tell you more about this mod when I will have something that is really working well.
At the moment the heated bed I'm playing with draws to much power (120 W) for my beloved Tina2 (60 W) which makes it reset if I don't heat up slowly step by step.

But hey... it works ! So stay tuned for more details when I will have solved this small power problem.
I have ordered new parts but it will take some time before they can be delvered from China.
