For rcfanuk

Here you go Steve.

LCD Cover


Raspberry Pi on the back of the LCD (Needs a reprint due to curling)


PSU Cover with Power Socket and Voltmeter


Replacement for those shitty wingnuts


Capacitive sensor from the top


Rear View showing the capacitive sensor


Relay box for the Octoprint/Raspberry Pi


Z braces


270mm x 210mm x 3mm glass bed


Video of the auto leveling in action. Note how far off the bed the capacitive sensor is even with the sensitivity turned down.

Most parts are straight from Thingiverse but the cover for the PSU was modified in Tinkercad to fit the switch and DVM
I drew the capacitive sensor mount on tinkercad. It's a simple L bracket with an 18mm hole for the sensor. it screws straight on to the original mounting holes for the inductive sensor.

Wiring diagram attached for you.
I have an additional 12v regulator fitted inside the control panel case for future use (LED Lights) My sensor positive is connected to this supply but it will be quite happy at 24v.

I send a G29 after the G28 (home) in the start Gcode so it levels at the start of every print. If I want to do it manually I send a G29 from the terminal in octoprint

The mount is fitted with the sensor hole of the bracket to the top of the X carriage.

Sensor Mount 18mm



The plug and sensor wiring



The Diode is heatshrinked inline with the black wire
