Thanks again Zax, I will go and fiddle with resolution and the feed rate.
" Air assist helps to prevent burning and gives a cleaner image and of course a well setup machine is essential."
I have setup air assist and it seems to work well but for the 'well setup machine' I don't know so much. It is working well and for the price paid I reckon it is pretty marvelous.
To explain, I have been working with a CNC router/milling machine for some time now and had some success in cutting 6mm ply to make a wooden geared clock. Recently the software that drives the CNC machine was updated and they have added a (paid for) laser module. I had a laser unit that came with the CNC machine and thought I would give it a go. Total disaster and much wailing and gnashing of teeth.
This is why I am back here, I should never have left. I have tried to find what I need on this (and other) forums and hopefully will get back to speed soon but it is a bit of a struggle. I was 80 years old last year and things seem to take a bit longer to fit into place now. I think my mind is like a HD it has absorbed years of info and is slowing down, it takes a little longer to retrieve the info because of the amount that is in there. I think I need a defrag.
Thanks for listening, I will carry on with getting this machine setup at its best.
take care

PS The setup I have here is a bangggood 650x500 laser engraver with T2 laser, total cost (so far) less than £200. The other CNC machine is a Stepcraft 420 V1 with Vectric V-Carve desktop software, cost (so far) just over £600.
