no issues with rigidity with a bare linear rail? how did you go about it... is that a viable option instead of toro tube on a 500?

thats what you would think, right? but I am not so sure if that is really correct... When a fan pulls air, it creates negative pressure, which can lead to turbulence and increased resistance in the airflow path. This can reduce the overall efficiency of the fan... Some fans are definitly specifically designed to push air and may not perform as well when used to pull air. The design of the blades and the housing can significantly impact the fan’s efficiency in different configurations...
The air flow behind a fan is slow moving and wide whereas the air flow in front of the fan is fast moving and narrow

oh okay, thats what I more or less thought that you would do, but it sounded for me in Helges message that you are just reverse the spinning direction, so I was unsure if you are actually flipping it at the moment or if you are reversing the spinning direction... but now I also understand what helge was saying better, because indeed the blades are not optimized for pulling air, even if the spinning direction is as intended... the question is do fans exist that would be optimized to sucking in this formfactor?

I am just a noob reading along this thread, but what about actually reversing the fan? I mean flip it around and use it in unreversed... would that not improve the characteristics, because the blades would be working in the direction they were intended to?
also just an idea (I am not sure if this would be even possible without a major redesign), but what about putting the fan behind the hotend instead of front and then blow the air over the hotend as usual, just 180° flipped?

No Voltage on Octopus V1.1 J26 pins?
unless the wiring shown in the picture above is doing any of that I did not do that, yes hahah (I didnt change anything yet, so I can maybe still find whats wrong)
I even did use compressed air to remove any dust, to be sure there is nothing that could short...
and the whole machine didnt see power until friday... the board and pi was only powered once on my desk to flash it and everything worked fine back there...
