As i used old server-supplies for that purpose years ago, i thought i would give it a try. I ordered a Cisco WS-CAC-1300W from ebay for less than 20€ - you can normaly find them ~30€ if you search a bit. text/html 2021-02-22T12:36:46+00:00 Anonymous (anonymous@undisclosed.example.com) https://der-frickler.net/technik/cnc_controller/estlcam_controller Estlcam Mega Breakout Controller [Array][Array][Array][Array][Array][Array][Array][Array][Array][Array][Array] Features: * Cheap (<20€) and Easy to build ESTLCam controller based on Arduino Mega * DC-isolation (incl separate ground) between PC/USB and Inputs/Spindle Control -> prevents most of the USB problems with inverter spindles. text/html 2021-02-15T06:25:25+00:00 Anonymous (anonymous@undisclosed.example.com) https://der-frickler.net/technik/cnc_controller/grbp_esp32_ramps Grbl_Esp32 RAMPS Controller After building some prototype boards for the really great Grbl_Esp32 by bdring i decided to create my own controller pcb. As i had some cheap RAMPS shields laying around, i made a ESP32 pcb that fits below the RAMPS board and replaces the Arduino Mega. The board runs Grbl_Esp32 and is capable of driving up to 5 steppers - if RC-Servos are used, 6-7 Axis are possible. The board should offer a very cheap solution for smal experimental machines with up to 5 Axis or smal… text/html 2021-02-22T12:29:31+00:00 Anonymous (anonymous@undisclosed.example.com) https://der-frickler.net/technik/cnc_controller/machine_electronics_example Cheap CNC Machine Electronics Example Estlcam Mega Breakout Controller [Array][Array][Array][Array][Array][Array][Array][Array][Array][Array][Array] Features: * Cheap (<20€) and Easy to build ESTLCam controller based on Arduino Mega * DC-isolation (incl separate ground) between PC/USB and Inputs/Spindle Control
