Getting my project further

I know, but at least the machine can be worked with wood, I think the cost for the strong frame is not more expensive too much and the benefit is very different

yup, but you missing 1 important point, he'd like to build a CNC that light and versatile enough and able to assemble/disassemble , bc he already mentioned above he will transport this machine to Germany

That is easy, he can change the welding connection by screw connection. Anyway, I just want to let him know that his frame option is not strong enough and neêd be reinforced, that is the main point. Thanks

Hello first thanks for all your replies. I was convinced from some members to make it in steel. To have a strong solution for also cutting wood. It also became bigger now. I hope you like the drawing
In the end you will find some pictures.
Now i am looking for some material. I heard the second hand Japanese should be the best.
But i take what i can get:

2 x 3600 mm linear guide rail (don't have to be in one part 3x1.2m also ok)
2 x 1200mm linear guide rails
2 x 400mm linear guide rails
and of course sliding blocks

1 x 3600mm rack pinion
5:1 gear box to drive the rack pinion

4 x stepper motors

300 - 400 mm Ballscrew
Ballscrewnut
2x Ballscrewsupport

If anybody have this part I would be very happy to buy them.
