Topic: New Nozzle = strange behaviour

So after clogging my nozzle a couple of times and finally not being able to get it cleaned out well enough, I bought a new nozzle and put everything back together again.  After trying a few prints with this strange behavior, I went back through the calibration process and found that the cube I printed had a wall thickness of .35 and not .42 like I expected.   So is that thinner thread what is causing the strange prints with threads not even close to each other?  I tried adjusting the Extrusion Multiplier up above 1 to increase the wall thickness but it didn't do anything.  Does anyone have a suggestion on what I should check.

Thanks in advance!

FYI I also have a Robo3D and the support by the company and by the forum users is terrible.  I can't thank you all enough for the welcome and friendly responses I have received here!!!

Re: New Nozzle = strange behaviour

Have you adjusted the steps per mm in EEPROM to reflect 100mm's called for equaling 100mm's pulled into the extruder?
Then adjusting the extrusion multiplier to reflect a wall thickness 120% of nozzle diameter?
If your nozzle is .40 you should be looking for .48 single perimeter wall thickness.

Re: New Nozzle = strange behaviour

1) Check the gap between the nozzle and bed.
2) Change the slicer setting to try different patterns on top surface.
3) Try to increase temp of extruder, from 215--220C
4) Calibrate Y drive again to reduce the backlash.
