I tend to agree with you. I am trying to envision a bench test that would mimic combat conditions. First you have to decide the USUAL / MAX fps of cannons on the water. Then you have to factor in fps after multiple rapid shots. I have hits on my superstructure 1- 6" off the water. (these are probably ricochets) What is the fps of a water or deck ricochet ? FOG of WAR A bench test could tell you the max fps a material could withstand.
Hardest gun I ever built would go thru 3 to 4 inches of pink foam (2x 2in blocks). Never put it in a ship as the thing damaged the breech l or bend to the point of unserviceable in only a few hundred shots. I do use 2+ in of pink foam as my BB gun ref when trying that kind of test.
I have had no problems with my Ender 3 a wise man on this form warned about a certain other model... "No anet a8 (which is an i3 clone/knockoff/pattern/etc) - friends don't let friends buy that shit. Right now the best bottom end bang for buck is the ender 3 (you can even buy the thing from Amazon these days - https://amzn.to/32uoaZb - but it is sale season so shop around!)" Thanks again Nick
Bought mine a long while back. As said it is good for a few parts lol. Rest is just barely good enough to print the parts to make it into a very competitive machine. Just not out of the box lol.
