Papa, don't be ashamed to post your laser projects... I'm not, and if you like, I can loan you a few layers of skin.

LB can be used as a free trial for 30 days and that can be extended if you ask. You "buy" the software for a 1-year period that lets you use new versions as they come out. If you let it expire, you still have full use "forever", but are stuck on the latest version that came out during your year or any earlier version. 

Now that is more civil than bloody SketchUp... While I love the product, I refuse to go subscription (as with many other products) as when the sub runs out so does your use.

But we're not here about SU license , but laser... unless it's SU design for laser.

Is masonite harder than MDF?  When I bought my laser and upgraded the wattage from 10W to 30W... it wasn't based on speed of cut but rather the thickness it could handle on different types of wood... I've contemplated upping the wattage to handle thicker stuff but the 5 figured shekel quote would put too much of a dent on future Fe$tool purchases...
That's why I go the dowel aligned laminations... which is what you (Splinter) could do to up the 3.125mm thickness.
The thing I hate about multi passes is the extra burning of the edge.

Hey Pottzy if you read this, how the hell do you use imperial if you don't know how to use the shift key on your keyboard. You should petition The Donald to change to metric to keep your shifty faith.

If your first cut is too short... Take the second cut from the longer end... LBD
