Hey everyone. I am very pleased to announce that I have founded the Madrid Rocketry club in Madrid, Spain. A free to enter and participate club for both beginners and experienced rocketry hobbyists! The idea is to get together to launch medium and small scale rockets, this is not an official registered club or company etc. The purpose is to launch rockets from safe and authorized locations in the Madrid area as getting authorization for these things in Europe is a pain in the a** (meaning i will take care of all of the bureaucratic stuff) all the clubs near Madrid I could find are closed to the public meaning they are from unis or for competitions. When I moved to this beautiful city I was hoping to enter a club like back in the U.S but there weren’t any! Anyways that’s it if you have any questions feel free to message me and che out the website!!! madridrocketry.com

Hey everyone, I recently built my own 3d printer although building it appears to bee the easy part, I also built marlin firmware for it, specs are: skr v1.4 24v PU 1 extruder, 2 z-axis motors. Overall I have no idea whats wrong, i get like this weird swiss cheese and it's different from print to print, i also se that on just the 3rd layer i get weird "gaps" it's calibrated perfectly, I also don't believe that it might be heat creeping but I guess it's possible my main theory is the part cooling fan is aligned incorrectly but i've tried printing new ones which turn out really bad. If anyone knows what's up pls let me know I would really appreciate it. I also think it could be the cura slicer but I don't have a single clue on how to fix it. In some of the pictures it appears i don't have a hotend fan but yes i do i just removed it there to show the inside of the extruder. And the hotend, nozzle and heatbreak shown in the extruder picture are old, I've recently changed them thinking it would fix the problem.

More specs:

PLA 210^C and 60

25mm/s

Cur slicer
