Hotend1.jpgHotend2.jpgHotend3.jpgHotend4.jpg
The hotend is like a hinge. When the nozzle touches the bed the hinge moves to activate a small micro switch. A light spring returns the hotend to it's printing position (only 2mm movement)
The hotend shown in these photos is working well, but I have noticed that it could be better,so I have designed another one that has a longer arm to increase the leverage and reduce the movement needed to activate the switch. The short version as shown works, but there is some deflection when the probing takes place as the X carriage is extended.
Yesterday I re-designed and printed the new part and I will try and test it out with the settings I have presently (although the settings are not perfect yet)
