Anycubic Kossel Switch and Controlbox

thingiverse

I needed to keep track of my printer's voltage and current, so I built a small box with a voltmeter and ammeter, along with some switches. The box fits snugly next to the standard display when it's moved to one side. For mounting the switchbox on the printer, you'll need 4 T-nuts M3 and 4 screws M3x10mm. The front cover requires 4 M3 screws, each 5-10mm long. The display shows the voltage from the power supply and the current consumption of the entire printer. To make this possible, a shunt was installed in the power supply that allows currents up to 50A to be displayed. Next to the display are two buttons: one for the LED lighting and another to cancel printing (Killswich). A raspberry pi with the enclosure plugin for OctoPrint controls these functions. The switch on the side makes it easy to turn the mains voltage on and off, which is convenient since the original switch is located on the back of the printer. Here are the parts I used: - DROK YB27VA-50A Dual Display Digital Voltmeter/Ammeter, DC 0V-100V/50 Amp, +50 Amp/75mV Shunt - 1 round Switch 21mm cutout diameter (on/off) - 2 Pushbuttons 18mm cutout diameter (normally open) - Some wires and crimp connectors You can download the .skp files if you want to recreate the switchbox or modify the cutout diameters for the display or switches.
