Components

We chose the Spindle-motor from AMB "1400FME-P for ER-16 precision Collets",
AMB1400FME-P
and 4 Nema23 Stepper Motors - HighTorque - 1.8 degree/step, 345oz-in
Nema23-stepper-Motor-254552446
Travel (Work Area): X Axis 740mm / Y Axis 820mm / Z Axis ~70mm
Workable Material Height: ~70mm
For the electronics we added an Arduino Mega 2560 with a RAMPS-shield

ramps
We are using some external drivers for the stepper motors:
Microstepping driver TB6600
DriverTB6600-P

Firmware

The firmware for the Microcontroller is Marlin 2.1
https://marlinfw.org/
This is the modified version of Marlin that is running on the Arduino Mega:

It can be uploaded with Arduino 1.8.19

Accessories

There is a set of ER-16 Collets (2, 3, 1/8'', 4, 5, 6, 7, 8, 9, 10mm)
and milling bits (2, 3, 4, 5, 6, 7, 8, 9, 10, 12mm)
collets
A modified spring-loaded Ballpoint-pen can be used for drawing.
