hello everyone, this post is to recomend new add ons for a next rev of the control board

- ICSP header for upgrade bootload and to programmer
- GPIO headerfor use the free GPIO of the controller (autobed level)
- POWER header for have 5v 12v 3v3 and gnd power avaiable (servo power)
- tx0 and rx0 header to change com (bluetooth)

more?

We'll consinder that on the next rev, tks for your useful suggestion!
and you can check this link here for bootloader:

My 5 cents too:

It will be nice to have an option to connect photoelectric ("opto") end-stoppers to GT2560.
It will greatly improve Z axis tolerance.

I would suggest moving to better connectors for board and bed.
I do a lot of ABS and have already burned board power connector. Bed connector is showing signs of overheating.

my recommendation would be to move to screw style connector.
I have all so measured bed mosFET reaching 93°C+ when heating bed.
