Power supply
Can anyone post the specifications of the power supply, specifically the output specs.

What type of connector is on it?

Does it show the polarity for the connector?

@Blackbart42  thanks.

I'm wondering how much power the hot end consumes. With only 3 amps to use it wouldn't be surprising if the hot ends inability to go over 215°c is related.

It would be interesting to know how much the boards power controller is rated for.

Standard TO220 power stuff in the  main controller, don't even remember seeing a heatsink when I opened mine up

The TO220 is rated to 16A.

If the board is a true melzi board clone then it should be possible to put more amps into the board.
The melzi v2.0 is rated for 12v and 25 amps.

That might be a way to get the hot end up to higher temperature.

I think that type of adaptor is fairly common,  it might have just been the most cost efficenct solution to provide a power supply.
It's definitely something I will look into .

And, unfortunately, it came with only one power adapter for both the printer and the pen. Can only use one at a time.  :(

Looking around aliexpress,  those size and type of supply are less than 5 dollars a piece. Anything bigger is a separate power brick style.

I used to have a variable bench supply somewhere around the place. I might have to see if I can dig that out. ;)
