1. Unbolt the print head from the carriage and take the fans off to get access to the adjustment bolts.

2. Bolt up the adjustment tool to the head assembly. I had to loosen off both heads and retract them a bit first. Two nuts on each print head stem either side of the aluminium block. The nuts were very tight.

3. Using a strip of paper adjust the both heads until there is slight drag between the tip of the nozzle and the tool, which feels the same on both. ( I set one with a drag I liked and tried to get the second to match it )

4. Tighten up and repeat drag test.

5. Repeat step 3 and 4 until success is achieved.

6. Bolt it all back together and redo bed levelling.

That’s it. Works a treat!
