First, what’s the difference between purge and prime. I would think they are the same. My printer is very newly commissioned and prints fine with one extrusion print, but is failing on the kraken. It gets about 5 layers tall. The rest is a bird’s nest. I did notice it did not prime/purge after it changes nozzles. I have the prime and purge scripts from the default setup. Stumped as how to enable purge/prime.
