Agreed re: laser safety. Worse yet, the unit is just a little too wide (enclosure) for my desk, so there’s a gap along one edge looking ‘up’ below the side panel. I’ll need to seal that off too before I try lasering. I’ve also noticed the gaps around the touchscreen, not bueno. Definitely need a rubber seal or something around that too.
So far I’ve calibrated extruder. Ran a quick basic test print for stick (big 2 layer flat rectangle), decided I need to heat up bed and nozzle to about 55/85 respectively before running the bed calibration, as the first try just didn’t have any ‘squish’ to the lines despite a cold bed calibration just before. Think I’m going to design my own filament guide (yes, seen a couple acceptable looking alternatives on Thingiverse but heck, that’s the fun of this stuff).
