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.
