Arrived in good order, packed very well.
I purchased this model because I have used the other type available on Ebay etc.
Having the Water and Air pump built in is much MUCH better than having them all separate and scattered all over place.
The built in temperature display is a good feature, but why the separate switch to turn it off? might be for a different model.
The extraction fan is powerful enough and the built in filter works well
Just power it up and it's ready to go and GO it does! I run LightBurn and the VEVOR Laser is Ethernet connected.
It's Engraved and or Cut: Wood, Ply, (Laser Ply from PlyCo. works great), Masonite, MDF, Glass, Acrylic and other plastics, Anodised Aluminium.
It's low enough to fit under my benches, but a bit low to be comfortable to use, I raise it up on a pallet stacker, no problem.
The Laser was aligned perfectly out of the box. Internal wiring was neat and well connected.
(friends purchases from ebay had all sorts of problems, loose wires, loose and missing screws, Laser alignment way out etc.)
Connected a DIY rotary axis no problem, the Y axis relay switch makes it easy align Y then switch to the rotary.
Manual Z control is OK and has plenty of travel but I think I'll add a stepper to the Z axis, the Ruida Controller has the outputs, just need to add a Driver and Stepper motor which I already have.
This is going to be a perfect companion to my DIY CNC Router.
