Still no schematic for the K1 Max (the older mainboard for the 42-60s)

So there was a request here for a K1 Max schematic last year but it looks like the request went unfulfilled in the post. So I am asking again.

Just to be helpful in replying:

  • I don’t need pictures, I need the schematic.
  • This pertains to the older mainboard which supports the X,Y 42-60s stepper motors. Not the new one.
  • I really don’t want to turn the printer over just to open the panel and see what is connected. It’s heavy, time consuming, and it won’t tell me the voltages of any of the open power ports.

I want to see if there is an open 24v (but I’ll take 12v) port for an additional fan. I want to mount a fan at the top back, preferably, to act as an exhaust fan. I think that might solve our problems with printing PLA and keeping the lid on the printer.

Thank you for reading.

You can just hook up to power supply 24v terminal but it will be always on if you want do that. Or wire them in parallel to side cooling fan so it turns on when that turn on.
