I think the correct model is JSM 40, not JMS 40. I have this machine and I am satisfacted with it. When my machine arrived, after a long trip from China to USA and from USA to Brazil, I need to do some fix with missed screws. Sorry not help you a lot, because my english is very limited. I just engraver, not tried to cut yet. Engraver function is good . Do a search here in CNC and in Google for Artsign JSM 40 and you will find a lot of information. The machine use Newlydraw software, so read the link Software questions for "NewlyDraw" and the link Laser maschine DC-K40III . If you want, I can use a translator software to send you more information.
