home build CNC laser

Hi there!
Today in my first post i want to share with you a short review of my home planned and home build CNC Laser. It's some of my key machines and will take part in many of my introduced builds now and in the future.

First i had to tidy up and prepare one of the still unused rooms in my house. After that a short trip to IKEA, buying some commode and tabletop. 1.2 by 1.2 meters should be enough space:

At the same time, collecting parts for the frame. Aluminium profiles, stepper motors, belts, energy chain, linear stages and so on:

Rainy days full of home improvement passed and this is the result:

Active area is about 880 by 880 millimeters, realistic accuracy < 0.05 mm. Good enough for cutting wood, acrylic and engraving stone, stainless steel and much more.
The work is done by one of these 6W 445 nm blue laseriodes called NUBM44 out of these casio beamers. Enough power to cut easily for e.g. 4 mm plywood, 3 mm black acrylic, 1.8 and 3 mm MDF.
A little asrock mainboard with printer port drives the stepper motors and laser driver. The software MACH 3 is used to work off the g-code.

Later i added a watercooling system with active cooling of the water by a disassembled fridge down to about 10 - 15 °C, because in summer the ambient temperature went up to 30 °C, not good for the laserdiode.

So far for my first post on the board.
At the end a few words to my person:
Im come from germany. Maybe this explains the improvable english and the metric units as well as celcius instead of farenheit ;-)
Im 28 years old, and working in research and development since i've been 6 years old or so ;-)
By a german video cannel I become attentive on steemit and thought its worth it to be a part of it.

Greetings,
yours sincerely,
Ingo
