CNC Plasma Build: Progress, placement, and sorta squaring

Upshot: Talking through some decisions/difficulties with placing and squaring this thing. Topic index: 00:00 - Intro, placement, ventilation, space restrictions 02:57 - Building & bolting the trusses, adjustments for the axes 06:45 - Squaring & shimming If you have the same problem with grinding out slots, I now know the solution: carbide die grinder burrs. I had used stone grinders and Dremel-type cutters with my die grinder before, but it nowadays they make very affordable carbide burrs that will eat right through the nitride edge left by the plasma cutter. Highly recommend. The funny angle measurements ended up being the square after all. A few days after posting this, I remembered you can check a square by scribing a line with it, flipping it, and scribing another (assuming the edge you butt the square up against is straight). The more the two lines diverge, the more out of whack your square is. Mine came in a hair under 90, which explains how each corner was wider than that. The limitation of only being able to cut 3ft along the gantry/Y axis comes the width of the carriage rollers themselves, bringing in the X axes to align them, etc. It's safe to say that your cutting area will be about a foot less in each direction than your machine's footprint. This is also my first time testing out software video stabilization in ffmpeg, so hopefully that cuts back the Blair Witch effect of just being one dude with a camera phone. I did see one quirk where the video rotates suddenly, but overall looks like an improvement. I'll keep messing with the parameters, and at some point, will have to do a video about how I edit this stuff... on the command line. Do you even Linux, bro?
