G+_David Wiggins Posted October 13, 2016 Share Posted October 13, 2016 I stumbled across this today. Looks really fun, and extra kudos for the Binford logo. I wonder if this is the 6100 version? Any way, this project could present Fr. Robert Ballecer, SJ? with more opportunities to maim, er instruct the cranky hippo (it wouldn't do the silly plus link for his name . . Odd). It's a bit more to it than first anticipated, and he seemed to need to mod the Arduino firmware to be able to interpret the instructions for the engraving designs. I wonder if adapting this to Raspberry Pi would work better? http://www.instructables.com/id/Pocket-laser-engraver/?ALLSTEPS Link to comment Share on other sites More sharing options...
G+_David Wiggins Posted October 13, 2016 Author Share Posted October 13, 2016 Posting a response to myself? Ouch. Another guy one upped the above, using a gantry crane design. I like it. instructables.com - The MicroSlice V1 | A tiny Arduino laser cutter Link to comment Share on other sites More sharing options...
G+_Scott W Posted October 13, 2016 Share Posted October 13, 2016 I just did the first test on a laser engraver I built. Link to comment Share on other sites More sharing options...
G+_David Wiggins Posted October 13, 2016 Author Share Posted October 13, 2016 Well burn impressed across my arm! That was very cool. Nice touch placing the filter glasses on front of the camera. I really want to build one myself, but I don't really have anywhere to lock out of the hands of the youngins. Well that and maybe in more than slightly terrified of burning out blinding myself. Maybe. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted October 13, 2016 Share Posted October 13, 2016 I'd shy away from the Pi. A microcontroller is running a single tight loop program. A Pi is running an entire OS plus the program. The CNC lasers I work on, sure they got a fancy Windows screen. But that only for the human. The actual CNC is run from a custom built x86 board, only running the CNC. (program stored on EEPROMs in the next slot over.) Link to comment Share on other sites More sharing options...
G+_Scott W Posted October 13, 2016 Share Posted October 13, 2016 For my CNC I use a gShield https://www.synthetos.com/project/grblshield/ that connects to an Aruduino Uno, the Uno connects via USB to a Pi running a Serial Port Json Server ( The Pi is also connected hardwire to the network). I then connect to the Pi via any computer on my network and send the gcode to the Pi using Chilipeppr. http://chilipeppr.com/ Link to comment Share on other sites More sharing options...
G+_David Wiggins Posted October 14, 2016 Author Share Posted October 14, 2016 That makes sense. Rather than burden the controller with an OS just for the import, simplify the import outside before it gets to the controller. Thanks for setting me straight.

G+_Jason Perry Posted October 14, 2016 Share Posted October 14, 2016 So I have a new project I want to take on. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted October 14, 2016 Share Posted October 14, 2016 Just to make sure I understand how low cost this is. All I need is a DVD drive (which I have lots of) Arduino (I also have) 2 stepper motor drivers and A laser driver Link to comment Share on other sites More sharing options...
G+_David Wiggins Posted October 15, 2016 Author Share Posted October 15, 2016 Pretty much. You'll want DVD writer for the laser components, some of the housing for shielding, and the drivers you mentioned. A driver each for X and Y axes(long e there, acres. . Crazy language). Note that I think on it. Wouldn't it be x and z since it stays flat to the place if the table? I digress, I need sleep. tl;dr that's the beauty of it. Many if us have all the stuff.
