Description
Works with Bambu Lab X1/P1P printers.
It utilizes the 24V provided by the Bambu Bus Cable to power two barrel connectors, each with an on/off switch. Each 12V switch is paired with an LM2596.
Requirements:
Bambu Power Tap V1.3 PCB
2x DC Jack 5.5x2.1mm Female Connector
1x M3x22mm Socket Head
1x M2.5x22mm Socket Head
4x M3x4mm Screws
2x M2x6mm screws
2x LM2596 Stepdown (12-volt only)
1x LM2596 (12-volt and 24-volt)
Assembled units and kits for sale at 3DMachinist Etsy Store
The six-switch version is 24V only.
History:
I had installed LED lights on my X1C, using a 6-Pin cable to access the 24v provided by the printer to the AMS unit (by plugging it into the second AMS 6-Pin port). That worked great when I only had one AMS, but the cable length became a concern when I added my second AMS.
I designed a Power Tap box with a 6-pin connector to draw 24v from the 4-pin Bambus Bus Cable. I then added a USB Board to the STL design to provide additional options in the future.
If you would like to buy me a cup of coffee.
