As a sparky, I want to know the best way to cut a drywall sheet between studs from a switch up to the ceiling. How can I cut cleanly down the middle of the stud so the patch does not need plywood backing? Last time I tried using a Sawzall with a drywall blade, it was a disaster.
Are these OK to use as horizontal pipe couplings? I am doing some renovations and need to temporarily hook up my kitchen. Would they be a problem if I ended up leaving them in place permanently?
Or should I just use a shielded rubber coupling?
I’m printing SUNLU PETG on a Bambu P1S. The filament is dry.
I had this filament well tuned for other prints, but I’m having issues with some press cups I designed. The part itself is very strong for my use, but the bottom layer of the overhang flakes off.
Things I’ve tried:
- 245°C with 100% fan
- 245°C with 100% fan and 20% aux fan
- 260°C with 30% fan
- 260°C with 100% fan
- Overhang speed is 5 mm/s
- Line width is 0.48 mm with a 0.4 mm nozzle
Note the picture shows them upside down. The flaking is on overhangs. They come out looking good, the flaking happens when I run my nail on it.
Any suggestions on what to change?
