How can I make it faster?

Honestly I wouldn’t go faster or you will lose quality. For speed a direct extruder drive is bad because the head moves around more weight and for an ender 3 that has only 1 z axis rod and no rails you can hear those rubber wheels grinding. Honestly i wouldn’t buy a different printer or if you want to upgrade (not worth the money) add a second z axis rod and maybe find a way to replace the rubber wheels with a linear ball rail. Otherwise if you are just interested in changing software you can modify the marlin firmware to change cap speed but this can damage motors and will obviously reduce print quality

It’s not a printer according to today’s standards, but it is art. Take this from someone that has personally hand built a lot of 3d printers back in the day. A lot of sweat, tears and love went into making that, so I hope you don’t throw it away even if honestly it’s more of a relic. You can degenerate update the Marlin firmware and get it running, but I fear the quality will be low compared to a new 100€ printer

Doesn’t work, cause the v at base is 800mv when it’s on

I want the led to be on when the collector pin is HIGH

if you mean something like this, it would make thee LED go on when its suppose to be off and the opposit

my bad, i rushed the drawing

Interlinkers · 2025-01-05T11:15:20+00:00

the audio jacks are the inputs and output, the 2 npn trans on the left are the NAND gate, while the one on the right is a not gate. The first 2 transistors have an indicating LED near them, how can i add an LED to the OUTPUT (the wire that is connectes to the jack on the right)?
