Here’s a video of my Taz Auto Bed Leveling Modification. I based it on the Taz Mini. The bed corners are made out of ninjaflex and I added a Z-Max endstop to the printer. I used slotted shims to secure the bed to the corners. I attached a ground wire from the Z-Min endstop to the bed plate mount and I attached the endstop’s signal wire to the hotend. The wire on the hotend runs up to the extruder and heater/thermistor connectors where it connects to the extruder harness. Both of these wires have quick disconnect molex connectors in case I swap tool heads or if I want to remove the bed. This was just a prototype to get dimensions for the bed washers. Right now I’m in the process of making custom washers on my cnc. I also enlarged the wiper mount from the Taz Mini and attached it to bed plate. It barely fits on the bed plate so I’m in the process of designing a new bed plate or wiper mount. You can see a video of it probing and cleaning the hotend here: https://www.youtube.com/watch?v=Hx1q_GJC3_k&feature=youtu.be
If anybody is interested in the STL’s for the bed corners and the Z-Max endstop holder let me know and I’ll post them on Thingiverse. Also does anybody know if it’s possible to use this type of auto bed leveling without having to use a Max-Z endstop let me know.
