Details

The finished project should mill PCB's and laser etch materials like leather. The goal for the workingarea is 400 mm * 400 mm at least.

    Mounted the linear rails for the Z-axis:

    Mounted the Z-axis ballscrews:

    The entire system:

    The next step is to mount a big plate on the ballscrews and the linear shafts.

  • Another Test Video

    This is the secont test-video, now with the small Z-Axis and a pen to plot.

  • Mounted the motors outside

    5 months ago • 0 comments

    Now the Motors for the X-Axis are mounted outside, so the Working-Area gets bigger.

What kind of threaded rod/leadscrews are those? (From the picture where they are lashed together with cord). Where did you get them?

Are you going to make tutorials videos how to make one ?

Hi!
What type of motor did you use?
Where did you get the bars, plastic elements, etc?

Are you sure? [yes] / [no]

ebrithil wrote 4 months ago 1 point

For motor, i used a standard NEMA 17 Stepper motor, the BArs are standart item aluminium Profile, and the plasticparts are 3D-Printed, when the Project is close to the end, i will make it Opensource.

Are you sure? [yes] / [no]

Hey, what laser are you using or going to use? It looks like 445nm, but what optical power? And what about laser driver, are you going to use diy driver?

Are you sure? [yes] / [no]

ebrithil wrote 4 months ago null point

The 445nm laser was only a Test to see if my CNC drive the right way. Later im looking for a 1-2 W Infrared Laser and not with a diy driver.

I wanted to ask why do you need 2 motors for the x axis instead of 1?

Are you sure? [yes] / [no]

ebrithil wrote 4 months ago null point

If i would only use 1 Motor, then the linear shafts of the Y-Axis wouldt have exactly 90° to the X Axis shafts.

Are you sure? [yes] / [no]

Are you going to make the 3D files for the plastic open source?
This is a very interesting concept, as I am actually in need on a simple XY table.

Are you sure? [yes] / [no]

ebrithil wrote 5 months ago null point

Yes i will make the whole Project Opensource, but only at the time when i finished it. I have a full 3D-Model of the my CNC in SolidWorks, iI'm gonna publish it, but later.

Are you sure? [yes] / [no]

Matthew Gingerich wrote 5 months ago null point

What kind of control electronics are you using? I built something similar, but I designed all my motor controllers from scratch, so they aren't really compatible with existing CNC software. I wondered if you had any advice on off-the-shelf controllers. Thanks!

Are you sure? [yes] / [no]

Sure, for the Controling I'm just using the RAMPS Board from thr RepRap community and a Arduino. On it i run the Repetier Firmware. To upload Gcode i use Repetier Host, and to generate the Gcode i use CamBam. Hope i could help you.

Looks nice. Is the left motor for the Y-axis? If so, how are you moving the Y-axis? Are you using something like the coreXY mechanism (http://corexy.com/theory.html)?

Are you sure? [yes] / [no]

ebrithil wrote 6 months ago null point

The left and the right motor is to move the X axis. the Y axis isn't installed yet only their linear shafts. On these two i will mount another sledge, where the Dremel or Laser is gonna be mounted. I will post a Statusupdate, but not know because the belts dind't arrived at the moment.

Are you sure? [yes] / [no]
