If I remember right (and assuming it's the same as our bigger machine)... Gradient = Like an engrave but with sloping sides (and usually deeper). I think it's used for making rubber stamps and that kind of thing. Holes = A 'dotted' cut made of little holes, like the perforations between sheets of lo...

Hi Nigel, To get an engraved line to work, it will always need to be an enclosed shape with some drawn "thickness" - so to engrave a straight line, you effectively need to draw a long, narrow box. Line thicknesses in Corel do not translate into the Laser software, as they only define 'path...

I would second that - it has worked well for us even with the stinky gloop from cutting ABS.

First thing I would check is your cooling system - two things in particular... 1) No air bubbles trapped in the cooling water - particularly in the glass 'jacket' around the laser tube. Bubbles around the mirror (opposite end to where the laser beam comes out) can lead to very rapid deterioration of...

Hi There, We have done some tests using PETG, as it was offered to us cheaper than the equivalent acrylic - and we found that it is not half as nice to work with... It will cut reliably, however compared to acrylic... 1) Cut edges will scorch - nasty brown colouring of the edges that cannot be remov...

Also, the cut lines leave a ghost/thin engraved line about 5mm below and to the right of the cut line(s). As PhillyDee suggests, most likely you need to re-align your mirrors - the second 'beam' is most often caused by the laser beam hitting the edge of the circular hole in the end of the cutting h...

An odd shaped beam 'profile' at the first mirror certainly sounds like a tube problem - but there is still a chance that it is just debris at the lens end of the tube (tricky to clean and often forgotten). Take a look at This Thread - some really good tips there for diagnosing tube problems, and the...

Looks very much like the way our first lens went eventually. It's perfectly natural for the lens coatings to deteriorate over time - after all, they have a lot of Watts passing through them! Having a spare set of optics is always a good idea just in case the worse happens - but when we got ours we d...

I found this YouTube video a useful reference when I started having to maintain our machine... Laser engraving setup and alignment video ...the part about aligning your beam starts about 6 minutes or so in. I'd also add... - The guy in the video uses masking tape to show his 'reference shots'. Not g...

I'm focussing the laser the supplied ruler distance from the bottom of the head that outputs the laser. Is this correct? We use a slightly different machine, but on ours the focus distance is measured from the position of the actual lens, which is some way inside the "nozzle". From your d...
