basswood grid to fit inside F1
Instruction
I made a grid to fit in place of the metal base inside the F1 to use as guide when using UV laser
For this project I used a piece of 3mm pine plywood from my local hardware store.
On the first few tries I had some issues with cutting the wood without setting off the fire alert.
To solve this I used laser protective glasses so I could keep the F1cover up for better air flow. Since that wasn't quite enough (and also just to be safe) I held a fan right next to the open machine to take care of the heat and possible flames. This worked perfectly.
As for the cutting settings, I lowered the power and increased the speed of the laser. I did 4 passes and the cut was almost perfect, a fifth pass at a lower power setting could've probably helped pop the piece right off but it wasn't difficult to remove with the 4 passes, and I used a normal cutter to clean some of the lines.
Although the plywood base in the photo is a just about one mm smaller than the hole in the machine, I adjusted the size in the file so that it would be more exact. I didn't make another cut, my shape for the cut was 107.5 and I changed it to 107.8mm in the project file
As for the grid, you will find it in different layers, one group only marks the grid every 10 mm while the other crosses through those squares to give you a line every 5mm. You can easily choose to only score the larger squares if it works better for you. I used a lower power setting on the smaller grid so it would be a lighter tone and hopefully not confusing at a glance. I also added a centre cross that's a little darker to help centre whatever you want to engrave.
Hope this helps!
