You are making progress! I have also been busy trying to optimize flow rate and temperature. Still not happy with the first layer (w/o Cubeitmod).
Just some pics using t=220 and flow 0.035 (default) to establish a starting point. Have mad my own torture test, because at this time I realy have problems with details on domes and arches. Don't like the details now....
Now printing with modified settings t=210 to see if I can reduce threading, but is just takes so much time
