So i was thinking last night that all metal hotends would make it very easy to make a auto Z stop.
had a play the weekend using a E3D V4 hotend.
Crocodile Clip to the top of the hotend which runs to 1 wire of the Z min on ramps
Then some copper tape on the glass bed with a wire attached to the copper and then running again to the Z Min on ramps.
tried it and it seems to work
i thought humm oozing plastc might cause a problem. it seems to not.
heres a video http://youtu.be/PhacRCle_UE
Would be interested if other people try this and how they get on.
Dont blame me if it doesnt work and it breaks your glass!!
