Because the first attempt failed I started a second version. Here is a drawing of how I want to make it:

My new Z-axis construction:

I’ve gotten 2 pieces of guide rail from my internship company. Unfortunately I didn’t got the bearings, but I can make them myself.

Thanks to Jan, Roger and internship company.

I’ve got some things for my cnc today.

2 Z-axis:


3 Steppers:



3-axis stepper controllers

Thanks Rik

I’m going to drive the steppers with a chopper steering. I’m going to build my design around the L297 and L298 ic’s. The parts I’m going to recycle from the driverpcb’s I got from Rik (See the picture bellow). The reason I don’t use these pcb’s like this is because if I connect a stepper motor then it already starts to turn without a signal. And the input signals are not universal.

I went shopping today . I bought a pci card with a parallel port to drive my cnc.

I have had a bearing holder for my Z-axis made (I cant drill such large holes here at home):


Thanks Jaak!

I went to a metal store to buy a piece of aluminum bar (30*10*2000mm). I used this bar to attach the Z-axis to the X-axis. Therefore I also gotten a aluminum plate.

I’m also thinking how I’m going to build the X-axis. I think it is best that I make a metal frame with the guide rails mounted to it. Here is a drawing of what the frame is going to look like:

Today me and my dad made a part of the X-axis construction from steel square pipe.

Better pictures will follow when I get the bearings ready.

I made some drawings of a table where the cnc will be on.

Today I made the motherboard pcb of the stepper driver.

I bought 4 inductive sensors from Omron for cheap.

Thanks to Peter.
