Dirt Between Contact Points - Felix printers Pro Series Troubleshooting Manual

Felix Pro L/XL

4.4 Dirt between contact points.

Another cause for errors can be dust, corrosion or chips of plastic or metal that are stuck between vital electrical
contact areas of the print head. Also it is possible that debris can build up over time, especially when the printer is
placed in a dusty environment.
To correct this, the following can be attempted:
1. Remove the hot ends (see the manual for the procedure).
2. Clean the metal disc. Especially the faces that make contact with the magnets. Recommended to use
detergent like blue spirit, acetone, alcohol. After cleaning the disc should be free from dust, debris, metal
filing....
RECOMMENDED: Put non-electrically conducting teflon spray on the disc. This improves the probe working
and also improves the electrical contact for the long term.
3. In the print head itself there are also areas of attention:
Clean the indicated surfaces with a Q-tip with a small amount of detergent.
