Hello to the community.

My first language is french, so apologies me for my very bad english

Before showing my stuff, I will explain my project.

I'm a mechanical Designer.
I want to make master models to make molds for making composite parts.
In 2013, I bought a 3D printer kit. With a lots of difficulties I print some master models. But I was very despite.

In 2017 I found a basic Kit with motions and spindle to make a CNC routeur

It was in a corner of my workshop.

Recently I decide to check the components.

Last month, I have build the CNC terminal.

Its structure is based on Thomann.de 19" rack for musician.
The PC is a 1 unit height by 250mm depth with :
  • an ASRock mini ITX J3355B mother board
  • 4GB Ram
  • a Radeon HD4650 Graphic card, recently added
  • 120GB SSD Drive
I use the Parallel port to connect the stepper motors drivers and the switches with a break board
Spindle inverter is driven with RS485 connected to USB

I have installe The live CD of LinuxCNC
For me, this is the hardiest part of my milling machine. I will build the routing table when all the electronic will work correctly.

Thats all for this time.

Do you plan to use a Full KIT Sqare HGH vas it is the cheepest way to do it
and if you also can go for AL-Regular profile you will be fast in a chipping mode

The second picture of this subject show all the hardware that I bought in 2017.
Sliding are mades of 20mm square HGH. Motion is made with d.16 & 5mm pitch ball screen. Link between ball screw and stepper motors will be made with synchro belt with 1:1 transmission. You can see one of the pulley in the above video.
I have drawn my 8th project and I'm not decided of the way to build the frame. It will be probably AL profile ( Motedis ) and AL plate (wood @ for the beginning ?).

very good to start
and as time goes by 8th Projekt you will get into
Q: is there a reason for the leg length

and the HSS86 will get cheeper and cheeper on time
no need to go stepper from now as 4Nm is the same at 10times speed and more control

The legs connect the y-axis to the x guide rails installed on the sides of the table. x ball screws are under the table. the z stroke is 300mm. This explains the length. But this solution does not please me.
