Hello folks. I recently purchased one of the many cheap laser cutters from eBay (specifically this guy http://r.ebay.com/YIX0ji) and I’ve been playing with it over the weekend. Unboxing, setup, and testing went without much trouble. Calibrating the laser took a while but eventually I figured it out. I can’t say it’s perfect yet but rather, ‘it’s a work in progress.’
A couple of things that I immediately noticed and I was wondering if anyone here has any suggestions/recommendations:
a) Straight out of the box, its 0,0 position is about 25mm away from the left rail. Looking in LaserDRW and just about any setting I could find, it says that’s 0 for X. Manually I can move the head all the way to the left and still have the laser clear the rail, so I could conceivably print in that area, but I can’t figure out how to reset the zero limit on it. Any suggestions?
b) Alternatively, I suppose I can simply print wider by setting the proper size in the print dialog and shift the work piece over by that same amount (25mm or so.) But there has to be a better way, no?
c) Mine did not come with an air assist, do I need an actual compressor to install one, or can I use an aquarium AIR pump? Do I actually need a lot of air flow around the nozzle, or is it just to help push the fumes/smoke out of the way of the laser?
d) I can’t seem to figure out a vertical focus, or if I even need to deal with that. The reason I bring this up is because the bed that it comes with, has that spring loaded little “window” to supposedly hold a work piece in it, but that’s such a small piece! I can simply put my larger work piece right ON the bed and cut away. So I’ve been thinking of removing that bed all together and replacing it with a piece of sheet metal and a honey comb on top of that. However, without cutting the standoffs, this would raise the work piece by at least 1/4", so I was wondering if focus becomes an issue … and if so, how do I check/adjust/fix that?
And lastly, at least for the time being,
e) I’m currently only using the Chinese supplies LaserDRW by importing files I create in other applications, like Illustrator. But what I’d like to figure out is whether I can use Illustrator to create both engraving and cutting layers and load it in LaserDRW to have it do it all in one shot. Right now I engrave first, then do a second ‘print’ to cut the piece out. I won’t (or rather, can’t) use the pirated copy of CorelDRAW and CorelLASER that came with the thing, not only because it’s pirated, but also because the version supplied won’t work under Windows10.
