3D Printed Robot Arm - Part 2

This is part 2 of my 3D printed robot arm. You can watch part 1 at in case you missed it. For the data below, it is now mostly obsolete. You should use the info in Part 3. The CAD design of the extended wrist cap with the electronics inside is available at The PCB Eagle Board design is available at as well as the Lua code that I used to test the actuators in this video. The firmware is there too. This has the latest release of the firmware plus the stepper library built in. Just flash via esptool to your ESP32 board. The ChiliPeppr ESP32 for Lua Workspace was used to program the board and is available at Video on how to use the ESP32 for Lua workspace to upload firmware and Lua code on your ESP32.
