I recently decided to purchase an inexpensive laser cutter from Ebay (Here). Once I got it, I quickly realized that I would be VERY limited in what I could cut. I set out to get the laser cutter to work with some more standard software. After some web searches I found that the tutorials all involved some modification to cabling or some other strange work around. I decided I wanted to design and build a drop in replacement that would work with Mach3 or LinuxCNC (EMC). Here is my first motion test of the prototype.
I have started the process to manufacturer a PCB. If there is enough interest I may put together a Kickstarter to get a large batch of these done and bring down the cost. I plan to run some cutting tests tonight check back to see the results.
UPDATE: I decided that for now, I will just sell a few fully assembled boards a see how that goes. Boards can be bought here.
Nice job getting something to work with Mach3, have you tried it with EMC? I would probably be interested in a PCB when you get it done. I haven't bought a laser cutter yet, but this makes it much more appealing.
ReplyDeleteThanks, I'm really happy with how it is turning out. I haven't tried it on EMC yet but it should be compatible. It uses an identical parallel port pinout as many of the breakout boards made by probotix and others. I'll keep updating as the project progresses.
DeleteWhat is the kerf (material vaporized) when using these Chinese cutters? Gives me an idea of how small of items can be cut. Like clock gears.
ReplyDeleteI will measure some of the pieces I've cut out of acrylic tonight when I get home.
DeleteI just cut some .18" thick material and measured a kerf of 4 mil (.004").
Delete0.004" = 4 thousandths where in typical machining shop lingo 0.001 is a "thou"
DeleteWay smaller than I imagined. I would have thought a least a full mm of kerf. Oh the gears are spinning in my head with the things I could do! Thanks!
DeleteIn standard Electrical Engineer lingo (which Chris is) a "thou" is called a "mil", so technically you are both right.
DeleteMoar! I see that the boards are sold out. I'd buy at least one from you. Can you make more please??
ReplyDeleteI'm going to start a pre-order now for the next batch.

very nice thank you, is there a way to add control of the laser power as well?
