- xy axis stepper
- dual z axis stepper
- aux board with extruder stepper
- all steppers are TMC2130 fully customizable via firmware
- 24V power supply
- sensorless homing for x and y axis
- optical endstop for each z axis stepper
- inductive probe sensor for electronic bed leveling
- hotend E3D v5 clone
- temperature controlled 80mm fans for active cooling the stepper drivers

The printer is running smooth and silent.
Tips & Tricks:
I added a second Z endstop so I have on each stepper one connected to. The reason is that I experienced both stepper do not run exactly synchron which caused issues with the first layer. After every print I needed to check the bed leveling which was time consumption. With an endstop on each side the printer now levels itself with homing the Z axis.
Regarding the IGUS bearings there are a lot of discussions that they stick to much to the rods. I used a simple trick to get them running smooth. I assembled each axis with bearings and holders and put them in the oven at 75-80 degree for 10 minutes. After that they run perfect on the rods.
