This video shows a compilation of some tests we carried out with the machine and some results we achieved. Please note that this is a prototype and that the project is subject to change.

Software used:
* Eding CNC Starter Software Release for CNC310
* DraftSight
* EstlCAM

Some specifications:

• work surface area about 50 × 30 cm
• linear glides with polymer bearings, insensitive to contamination
• maximum speed of X and Y axes: 15000 mm/min, Z-axis: 750 mm/min
• repeatability: about 0,2 mm
• nema-17 stepping motors
• driven via reinforced GT2 toothed belts (X and Y axes) and screw spindle (Z-axis extension)
• Z-axis extension suitable for drilling, milling and engraving in wood, plastics and non-ferrous metals (aluminium, bronze).
Using Proxxon LBS/E spindle (5,000 – 20,000 rpm, 100 W)
• professional drivers and software from Eding CNC (cnc310 controller board)
• stepping motor drivers based on Trinamic TMC2160 controller IC’s for silent operation
• 2.5D software extendible to full 3D
• multi-functional design, can be extended for other applications
• can be extended with a pendant (= console with buttons and wheel for manual control)
• maximum power consumption without drill/grinder: about 100 W
• total mass of the machine including Z-axis extension and Proxxon LBS/E drill/grinder: 24 kg
