When the head is parked in a home position it will extrude with no problem? It is only when you start to print that it has a problem? All at the same temperature?

If that is true, I believe you have a software/firmware setting that is incorrect because it is mechanically working in the home position.

If you are seeing improvement, but not correction at 225--it may simple not be low enough and your temperature is still too high.

In either case, I do not believe a direct drive would fix you problem. If it is something drive related, mostly likely the gear that feeds the filament in is stripped and might need to be replaced. However, if that were true you would be getting the clicking almost all the time, it would not work differently in a parked position than in a running position.

I'm about ready to make a direct drive mount or something.

Start at 220-230, but the thermistor in Solidoodles is placed far away from the heater, and the temperature is actually higher than what it is usually showing on the screen. I usually run ABS at 200-210 and PLA at 175-185. If the temperature is too high it could cause problems like what you are seeing.

Out of curiosity, are you using ABS or PLA? and what temperature?

ABS at 250C

Now I feel sorry for the stepper motor:P how can I cut down on resistance through the bowden tube?

Yes it does extrude fine in park away from the bed. The problem happens only during the print. And by increasing the z offset I've managed to print the first layer fine, but it starts again on the next layers. Maybe my e3d v6 Bowden setup is simply causing to much resistance.

If you heat up to extrude and release tension on the idler bearing at the extruder, then can you extrude by hand pressure just pushing the filament into the Bowden tube?

Are you able to extrude with the nozzle in free air (not touching the build plate) without clicking?  If so, perhaps you are too close to the build plate for your first layer.

Also check the set screw on the extruder gear...
