Did you upgrade the chiller to a better unit you should get a real chiller not the 3000 that is just a fan.
Hi all
I have agreed on a price and a machine with Dropswell for their 100w 6040 laser engraver cutter
The package includes chiller and honeycomb bed. I need it to cut acrylic up to a maximum of 6mm. My main interest is prototyping camera systems for 3d medical scanning. The price is reasonable so is the warrenty and I like the layout of the machine

Anyone got any advice before I transfer the funds on Monday
Thank you
Jonathan

Definitely drop the 3000 and get a CW5000 or better. It always makes me a bit skeptical of a seller if they are willing to sell that chiller to their customers. No ethical dealer should even offer those at all.

Really grateful for the advice. The machine came yesterday and I have removed it from the crate and assembled it. Not a small job I must say!
The 6040 I purchased looks really good, linear rails and bearings, and driven Z axis. The electronics are very nicely laid out with quality wiring. I have purchased Corel Draw x8 and the next stage is to install the software and plugin contained on the CD. Manual is comprehensive and good pictures to support the slightly odd english translation.
So some more questions.
Ducting, the ducting with the machine is very flimsy so I am thinking of purchasing some more industrial grade. When cutting Acrylic, is it necessary to extract, how bad are the fumes?
Laser glasses, which one should I buy, is it necessary bearing in mind there are micro switches on the lid that prevent the laser from operating with the lid open. How much protection does the acrylic window in the lid provide?
Sorry for so many questions

>> When cutting Acrylic, is it necessary to extract<<
Definitely. Extruded will be worse than cast.
You pretty much have to vent everything. Laser cutting is going to be producing fumes and/or dust with just about everything and you don't want either building up.

Glasses are a good idea but mainly to prevent something from getting jammed in your eye versus laser damage from_a_co2_laser_like_yours. Think about it. For the damaging laser to get to you it would have to cut through the acrylic window first. Right now, you can't cut acrylic very fast normally when it is 18 mm under your nozzle. For it to reach your laser's window, it will have to bounce off the bed of the laser and then travel all the way up to the window, so it isn't going to have much cutting power.
