Generic pla plus (black and grey) vs polymaker pla pro (gold)

I've had a few test prints in the back on a hot car today and I found some weak points. Don't buy cheap filimint. The Polymaker PLA pro did not warp where the generic brand did. NOW the extra length of the early version of the stand alone vs the shorter PIP v2.0 may be a factor but it seems like the polymaker was much firmer right out of the trunk. Several different prints in both versions showed warpage.

The recievers did not show any signs of warpage regardless of what material they were made of. I can only assume the thick chunky mount is keeping it from warping.

The chassis and handguards did warp with the cheaper pla + but did not warp with the polymaker pla pro.

There is 0 signs of wapage even at the thinnest points of the polymaker pla pro.

Kind of makes me wonder if repeated cycles of hot and cool say from placing a print in a container of salt for a week or two in the trunk would anneal a print?

It's a p1s .12 layer heigth .10 .10 on your fuzzy skin settings. Use good quality materials (big fan of polymaker pla pro) for basic stuff. My suggestion is to follow hoffmans word like he's JC, half suspect he's state sponsored he's so good. Watch his videos from start to finish starting with the old ones. When he breaks or has issues he documents the failures and comes up with solutions. He does change his mind at times with experiance.

I'm using the bambu slicer for all of my modeling as well. I'm just an novice at this, I just know how to stand on shoulders. I have alot of room for improvement since I have 0 cad experiance and I'd rather be with my chickens than a computer. Anyone can design anything with this technology.

Building off the last guy is why this can never be stopped. A good project.... like the FGC9, will be tinkered with and improved years after the passing of jstark.

That said... cheat..

When you find a good print profile import another object than delete the origional.

I'm fairly certain. I borrowed my settings off hoffmans sl15 file. I'm not a old head, and my machine realllllyyyy needs to be serviced.

It's like a good old 1911 that's been through 3 conflicts or that m4 that's been in Iraqs fine dust for 10 years that you can cock with your little finger. When some things are not properly maintained they can get.....better.

Atleast that's what I tell myself. Should probably rub some grease on the rails again.
