Sorry, I promised this video couple of weeks ago, but I wasn't able to record it until now.

As you can see, the 1.22 board is working fine, then I replace the board with the v1.21, and check the resistance (my multimeter fluctuates a lot, but it does the same with the good one, and the values is around 600 when it comes "steady"), then you can see that the led don't blink and that the VR1 is near the point where the led changes from on to off.
Any advice to have it working again?
Regards

Thanks for that video. That is what I am now seeing too and reported a few days ago - but I only have the one board :-(

You should do a post mortem on these boards. The protection may not be sufficient. Piezo can produce very high voltage spike.

We are very aware of that, and so far have had a very low failure rate something in the order of 3 boards out of 300, which given that the design has been constantly evolving and they are presently handmade, is lower than I would have expected.
I have one of the first V2 universal kit boards on my microdelta printer, and it has been constantly powered up, and in use for 3-4 months now, with no sign of any issues.
One of the great advantages of using a PCB like ours is the protection it offers your 3d printer controller, an (often) more expensive component since some advocate the use of piezos wired directly to endstop channels.

With most slicers although this refers only to slic3r/pe with any certainty, if you use a temp command in start gcode like M109 then the default heat up gcode normally inserted before the start gcode is not inserted.
I use
M104 S130 ;heat hotend don't wait
M190 [first_layer_bed_temperature] ;heat bed
G32 ; autocalibrate
M109 S[first_layer_temperature] ; heat hotend until stable
Plus a bunch of other stuff.
Those variables work in slic3r other slicers may vary.

Mega-Ohms.
I am truly sorry, I should have written it MOhm's right?
Anything else?
