I might have 3 sets ready in the morning. I will update the inventory after I pack this weekends orders. Then I get almost 1 set done a day now.
Get the bigger power supply if you are going to add the laser. It’s just easier than adding a second.
What kind of issues are you having printing PLA? Do you have an all metal hotend, they make PLA difficult. You’ll need to print faster if you do to keep the heat from creeping up the filament itself.
