Hey guys, I need to purchase an intrinsically safe (plastic body) light for work.
What are your favorite compliant lights?
Mainly looking for the best lumens/price ratio and best durability.
Ideally looking for 18650 powered but I guess AA would be ok too. Trying to stay away from AAA.
Regardless of material and temp, my 1st layer always has these weird striations in some areas of the solid infill. I keep all my material in a heavily desiccated dry box. No snap crackle pop sounds while it’s printing.
Feeding from a bearing filament roller through a bearing filament guide.
-Printer is a Prusa MK4S
-Using polymaker PETG at 240 C for 1st layer, as indicated by my temp tower.
-1st layer speed is 20mm/s
-Sliced in PrusaSlicer
-firmware is default
I hear this weird intermittent grinding noise sometimes. I checked the tension on the belts and have run all the calibrations.
I’m at a loss here guys, please help me out.
