This Frankenstein Laser Cutter was built out of an old scanner and printer.
The whole thing evolved around the instructable of Groover and his 'Pocket Laser Engraver'.
This is a Making-Of. Although a lot, if not everything, of the mechnical construction requires ingenuity I tried to document the complete build process as much as I could. Every scanner and printer mechanics are different so this could not be used as a step-by-step guide. More of a "how it can be done"-guide. I try to cover the questions that could arise in the process of making.
I had absolutely no clue about electronics. All I knew was that RED is (often) + and BLACK is (often) Ground.
Therefore I have learned a lot in this project. Starting from mechanical stuff like self-replenishing brass bearings to electronical stuff like stepper motors and the difference between bi- and unipolar motors to soldering and etching my own board.
The work area is 270mm x 200mm. Just about right do cut some flip-flops for the summer.
It is able to cut :
It can engrave:
|Easydriver x 2||20 €|
|Electronic bits and pieces||10-15€|
|Aixiz housing /w lens||6 €|
|Laser safety glasses||50 €|
|New total||100 €|
May, 13th 2013 : Added Step 17 - Links and files section
Added Step 18 - Take it to the next step (Improvement - optional)
Updated BOM list. Now contains more stuff you need
May, 20th 2013 : Corrected mm/sec to mm/min ! Seconds would be very very fast.
June, 1st 2013 : Added Step 13 - Alternate laser driver shield (Easylaser Shield)
December, 4th 2013: Updated Alternative Easylaser Shield schematic/layout with the help of jduffy54.
