Qidi Tech 1 - Replicator 1 clone

[KludgeGuru]

Anyone have any idea what sort of RGB LED strip would be compatible? I would love to disconnect the single color one and replace/add the new one that can change colors (ie red for heating, blue for printing, green for done). Just an idea.

I took a closer look at the Mighty Board and the schematic. It is not going to be as simple as just connecting an RGB LED strip to the connector. It looks like to save costs they did not populated the RGB driver circuit. To get it to work your going to have to solder some components to the board and you will need some good solder skills/equipment.

Here is what you need:
U15

U19

U16, U17, U18

R113, R114, R115

They are driving the RGB LED strip from the 24V supply. If you can't find a 24V strip then you could run a 12V strip (which I believe is more common) by adding a small 12V power supply, or hacking on a 12V regulator.

Make sure the RGB LED strip is Common Anode type.

This is all assuming that the firmware is actively trying to talk to the U15 driver, my guess is that it is... unless Qidi purposefully disabled it in the code.

I may eventually try to do this mod. If I do I'll report back my results.

You may be able to use one of these for the voltage reduction.
