I have had my 6040 yellow/black Chinese laser cutter for a month and find that I need to use the pass-through ability that it seems to have. But the 6mm ply I want to cut will be too high for the lens tube. At the front of the machine is a removeable panel about 5cm tall by 60cm wide. At the back there's an opening about the same size without any cover. I can feed my sheet of ply through these slots and it rests on the welded frame that's sited around the Z axis table. So I understand that I won't be able to adjust the oversized board for height. Unfortunately, the lens tube extends down to just below (5mm or so) the top of the board. The current lens has a 2.5 inch focal length, so I'm thinking if I had a 2 inch or 1.5 inch fl lens and a corresponding shorter (or adjustable) tube I would be able to clear the board easily.
My lens tube setup is the gold-coloured 18mm lens diameter type of assembly (K series?), which are sold on Aliexpress / Amazon etc. The bottom portion is threaded and allows some adjustment but it's already 1 thread from the top
My questions are...
1 Am I right that my machine has pass-through capability?
2 For you guys with that have this feature, how do you set focus on long boards?
Pass-through help needed

Been there done that. Had to get longer lens tubes to be able to put material in my lower door. The lens tube and nozzle supplied had the focal point right on a cabinet brace. See pics. https://drive.google.com/drive/folders/ ... sp=sharing

Trevor, you are on the right track I think- you probably need a different [more adjustable] laser head- if you look on Cloudray they have a number of different setups for illustration. For a larger wattage tube you would normally see a bigger lens and in my experience either a 1.5 or 2.0 inch focus lens. Most tubes are adjustable for length which is what you are needing. These machines have no 'normal' configuration, the Chicoms are kinda lax when it comes to what should be used as opposed to what they have on hand.
