PCB LASER CNC
oldschool:
I must realy admit, to read your replys is real inspiering. Truly. I lern from your post more as in last few month browing the net.
Fackt is that, lasers are realy pain in the ass. I have cnc laser machine in budy s house but co2 tube broke becose of lackof colent. Sooo,.. i coud put laser diode there but i think it wont work. Vibratins are huge for smal objects to print.
If i wont to build laser it seems it is realy pain in the ass to build it corectly. And if i think that laser must print on clad bord from half an hour to few hours is time consuming too.
A lot of option to consider. I love laser it is sexsy but,... it can eat my nerve a lot too. Specialy if i took this diode https://www.ebay.com/itm/405nm-500mW-Focus-Dot-Engraving-Laser-Module-12V-Adapter-Violet-Blue-Diode-Carve/321910367592?hash=item4af35a6568:g:9V8AAOSwLwBaeUOX or similar without fokusing laser and so on. I watced some videos form you tube.
Tones transer is nice option in fakt i try it once yers ago, but printer problems kiled it. Comercial paper from comershals like interspar, hofer und sutch and print it. Didnt stik, holes, this that. I read on the forum some peole use a lot of time to master it, with right printer those days.
I can buy coper clads for realy cheap as left overs from industry production of pcb s. so i found this video https://www.ebay.com/itm/405nm-500mW-Focus-Dot-Engraving-Laser-Module-12V-Adapter-Violet-Blue-Diode-Carve/321910367592?hash=item4af35a6568:g:9V8AAOSwLwBaeUOX
If understand corectl this person uses aduino bord with some caind of sheeld gerb on witch he ataches steper moter drivers and then steper motors with power suply and usb cable to the computer. Ok i found this https://www.ebay.com/itm/3D-Printer-Kit-CNC-Shield-R3-Board-Stepper-Motor-Drive-Limit-Switch-for-Arduino/263837593803?epid=23021788194&hash=item3d6df230cb:g:CN8AAOSwBqZb3Q13 or https://www.ebay.com/itm/CNC-V3-Shield-UNO-R3-for-Arduino-Compatible-Board-4x-TI-DRV8825-D3U1/132300836009?epid=2190523849&hash=item1ecdbe8ca9:g:0rkAAOSwRJ1ZmHPh.
I have build cnc mill form scrach, i mean elektronik part totaly, drivers power suplys, contorelrs and so on. But how do you program aduino to work. If i understand corecty you must upload to aduino some code or program to work, then you need program to make somthing. I am not familiar with this type of sistems, ( i now that whole world is using them adn so ob enbeded systems).
i think i will avoid laser ploter becose if i undestand corectly i need realy good rails suports an so on, and laser fokusing thing, to me is money not good spend. I will ratehr wait and build sturdy machine then i can put on it laser and spindle and so on with proper servo control.
But this flomaster ploter cnc marker thing can be build for cheap and fast. this woud work. Only problem is i am not familiar with aduinos |O. (i have nukleo at home, try it twice i didnt get nowere, it woud me nice to heve soem turtorial for the thing)
Naice day to all and thank for your answers.

Well, there is a really big (417 pages) discussion of such machine from shit and sticks Chinese laser diode and DIY mechanics (former inkjet printer plus stepping motors) / controller (STM32 based plus webcam). But it's in Russian.
