Howdy. Printing Loose change and some of the bengle PD's. Intending on doing a 70:30 mix of pyrodex and aluminum powder, but as I look to buy powder it looks like there are a few different types. How particular is it that one be obtained over another?

Was going to buy a few pounds of this dark aluminum but also see that they sell a few different types of aluminum powders.

Any suggestions?

Just became aware that Fort Worth was one of the concert locations and checking the website it shows that tickets are not available for purchase on the venue's website. Does this indicate that tickets are sold out of that they are not selling them on the site currently? Probably a dumb question but DFW is much closer to me than houston.

Thanks!

my macbook pro M1 is using its fan for the first time in 5 years. I didn't even know it had a fan. is this going to kill my machine?

0.2mm nozzle
0.1mm layers
Print speed 30mm
5mm/s over bridges and steep overhangs
100% part fan
temp tower 245-235 (reprinting some in lower temps rn)
current max vol flow = 2.5
settings said min print speed was 10 mm/s but I'm dropping it to try and see if that will improve cooling on the bridge.
thick bridges

fully dried at 65c for 36 hours
1mm retraction

I am half tempted to drop part fan to like 50% on bridges and overhangs and crank the print speed significantly to try and outrun the drooping.

any suggestions/advice? I am running the 0.2mm nozzle as I am attempting to make a TPU matrix that is less rigid than a normal infill. goal is to hold thread under tension.
