Just another tech blag
I saw a cute keyboard online at one point, an absurdly small keyboard, 35%. I decided to build one myself, there’s a kit available with the circuit board and diodes, just add switches, micro controller, and case. I did end up complicating things a bit though, adding hot swap sockets and I plan on eventually adding a plate as well.

Way back around 2013, something started getting popular on Instructables, word clocks. They gave the time as a sentence instead of a usual number like most common clocks. I thought these were cool and wanted to build one, I even picked up parts, but never got around to building it.

It can’t do path operations on groups, and sometimes InkScape will put a single object into a group. You can combine paths and do boolean operations on them that way, but that is using the path combine tool, you just cannot use the grouping feature.
You can’t use object operations on it for LightBurn to understand it. No use of object clip or mask should be used when creating files for use in LightBurn. You can make use of path difference or intersection to make changes to similar effect when avoiding the object tools.
I’ve been using the ortur laser master 2 for a while now, and while I had seen plenty of chatter about the G8 lens, I didn’t think it would be that major of an upgrade for me, but I was Very wrong. I recently picked up the G8 to try it out and once it was focused, the beam was tighter than it ever could be with the stock lens. This gave me high hopes for the test cuts.
I ran one cut job on some brown AstroBright paper that I was using a few days ago. With the stock ortur lens, I found that 900 mm/min at 100% power for 2 passes would give a clean cut through and require minimal to no hand work to split the papers apart. For my test with the G8, I started with one pass, and that’s all I needed, everything was perfectly cut apart, no tabs between the pieces, nothing. I did run into one snag with that first test run, some of my cuts were inaccurate, lines not lining up and some corners shifted. I noticed while focusing the lens that it was really loose in the mount. I pulled it out, put 2 wraps of teflon tape around the threads, and put it back in the laser. Second test cut went 100% perfectly, all pieces fell apart, no shifting of lines/corners.
The G8 lens is absolutely worth getting and installing on the ortur laser master 2. The tighter focus will help with both cutting and engraving and let you run the machine faster.
