My ongoing CNC router project - (work area: 2700x1700x200mm)
Hello.
As I have promised, I will describe CNC project I am working on right now.
From the beginning when I wanted to build a CNC router I thought, 1200x600x100 in work area is good enought, but the MDF sheets have 2400x1200 mm. So why build a machine that I have to cut MDF sheets to fit them on router table?
So I left this thought be in my head and started to buy electronics and motors.
I got this:
- 4x Nema 34 8,2Nm stepper motor driver (6A)
- 4x M880 stepper motor driver controller (7,2A max 80V)
- 1x mother board
- 1x "big ***" PSU. 48V 24A constant load with 6 stepper outputs
- about 550kg of steel
- 25mm shafts (2x 3000mm, 2x 2000mm, 2x 500mm)
- 8x 25mm open ball bushing
- 4x 25mm closed ball bushing
- 10m of 25mm shaft support
- 3x 25teeth 25mm pulleys
- 12m 25mm reinforced belt
- 1x 14x3mm screw with mutter
- 1x 12Nm coupling
- 1x Kress 1050W 230V router motor
I think it is all the parts.
Under welding my router table looked like this: cnc_table.jpg
The router table I build in Poland as steel is much cheaper there then in Norway. So right now I am waiting for steel to come from Poland.
My gentry will look like this: cnc_gentry.gif
The table is build from 120x80x5mm steel profile, and the gentry is build from 2 of those profiles welded together.
