Raise3D PCB trace repair
Toolhead breakout board with missing traces, plus hot end clean-up and heater test
A batch of Raise3D toolheads came in with burnt-on plastic and a breakout board that had lost traces at the fan connector. We cleaned and tested every hot end, rebuilt the broken traces, sealed them with UV-cured solder mask and put the toolheads back together.

What we did
- Check every toolheadEach toolhead was inspected and checked with a thermal camera to see which parts still heated and which had failed.
- Clean the hot endsBurnt-on plastic was removed from the heater blocks and nozzles so the parts could be tested on their own.
- Test the heatersEach heater was run from a bench power supply (12.5 V, about 0.7 A) and watched with the thermal camera until it passed 160 °C.
- Find the broken tracesThe breakout board was taken out of the toolhead. Traces at the fan connector were missing and the connection was open.
- Rebuild and sealThe missing traces were rebuilt, the fan connection restored, and the repair covered with UV solder mask cured under a UV lamp.
- Reassemble and testThe board went back into the toolhead, and the fan and heater were checked again before the toolheads were returned.
