First, thank you for your interest in this project. One of the best features of our community is the opportunity to collaborate, learn from each other, and have a good time doing it. I’m looking forward to this group build!
Second, we have some decisions to make. This note is to share a few ideas with you. With input and a little more research we’ll reach a conclusion on which laser etcher to buy. Do not feel as though you need to participate in this discussion . It will be technical and not everybody’s cup of tea; waiting for the final decision and going with the flow is perfectly fine alternative.
OK, so, what I believe that what we’re shooting for are:
- diode laser
- controlled by LightBurn
- supports grey scale
- $250 - $350 cost
The variables we will need to lock down are:
- power of the laser
- cutting area of the laser
- optional features:
- end stops
- SD card reader
LightBurn compatibility comes from GRBL 1.1 support but grey scale support isn’t guaranteed. Cutting areas start around 6"x 6" and up. Power options start at 0.5 watts up through 20 watts. Making choices on these is how we’ll arrive at our selection.
Here are two examples:
6"x 6" cutting area, 7 watt, GRBL (but don’t know version or grey scale), $225
12"x 15" cutting area, 2.5 watt, GRBL (1.1, upgradable w/greyscale), $350
Your input is welcome and feel free to search for options.
I’d like to quickly get down to one to buy for testing .
If results are good then we can buy in volume.
