Nice Project...
Whould be great if you share the cad files, so i could adapt to aluminium perfil 3030, and also share.

Awesome project.

is there a way that you can either add the gantry files or perhaps modify them for 2020 extrusions?

Can you make the cutting/engraving area bigger by getting larger x/y axis rods?

Can you make this whole thing bigger by getting larger z and y axis rods?

I have found that using a 3d printed bearing or cheaper set from Amazon resulting in a slight movement (up/down) during operation as the outer portion of the bearings are not truly round and wear unevenly. Would it be possible for you to post an alternate motor mount that has the roller bearings at 60MM centers vice 55MM? I modified my gantry and it resulted in much better movement, but would like the ease of being able to 3d print the sides and using the bearings linked below.


I think folks will get much higher quality projects with these better bearings. Thanks for your great design!

Hi! I made same engraver but have issues with movements. Can you please share your grbl setting $$ ?

can you cut with this laser?

Sure, but it depends which laser u use.

Hat jemand die fertige Firmware ?

Had nothing but problems with the roller wheels. Ordered a set, got tired of messing with it. Same with the spacers. As far as the gantry's, they warp and should be made of wood, metal or acrylic. Bummer.

Do you have a link of what you ordered or the sizes

There are things which are able to optimize, of course. But at this point it is as much as possible a "3D printed Laser Engraver".

This is what can be made out of it http://www.instructables.com/id/Laser-Engraver-With-Arduino-1/

Danke für den Tip, daraus kann ich was machen :-)

Schau mal bei instructables


konntest Du die DXF der drei Teile für Stevedee78 erstellen ?
Da hätte ich auch Interesse dran :-) Die Fräse arbeitet halt doch etwas genauer als der Drucker.

cant find the aluminium profile on ebay its all german on website

"I am from..." could help. ;)

Hey, the core XY design of my 3D printer (http://www.thingiverse.com/thing:500041) would make a very nice remix of your project. Thanks for sharing!

After many, many modifications, I made one of these, and it works flawlessly!

I´d like to see some pictures!

Good to hear. Feel free to post your modifications. What did you change?

I added the bushing right to the plates so that they print better and are perfectly centered. I split the Y-Axis pieces into 2 because my 3D printer can only do 10cm x 10cm and they were way bigger. I modified the laser mount, and made the X-Axis slider bigger so that the bolts don't touch the stepper motor. I modified the feet in a few ways. And a couple more that I can't remember right now.

Good to hear. Feel free to post your modifications. What did you change?

Hi could I get the following files to STP, PRT or DXF?


I wanted to mill the parts.

Hallo könnte ich die folgenden Dateien in STP, PRT oder DXF bekommen?


Ich wollte die Teile fräsen lassen.

ich kann die aus cinema exportieren, aber dann nicht anschauen ob´s geklappt hat

Ja probiere das mal. Wäre echt cool wenn das klappen könnte. Der ultimaker 2 tut es im Moment nicht .

How much does it cost to make

around 100€ without laser, controller and filament.

Thats clever idea to keep both gantry sides synchronized, sort of out of the box thinking.
