bulge after z seam when printing outer layer first
-
@RedMachine
Witch kind of machine, CoreXY? -
I set "extra prime amount" to 0.5mm3 for a quick first test, and it definitely under-extruded the seam. This is the first thing that has effected it at all, so I will see if this can dial it in.
The setting is in mm3 and I am trying to retract 1.5mm printing with 1.75 filament, so I I will try 0.18mm3 which should be about 10% of the volume.

have you try to print a cylinder in vasemodus? if not please do it and post the result
-
It is a plane Cartesian that moves the gantry in the Z axis.
-
How was the orientation on the bed?
I would print a cube, setting the seam to the middle of one side.
That would it make easier to relate to the axis. For me it looks more like slack or lose parts. -
I actually did try changing belt tension some. It looked at first to me like it was overshooting with the Y axis.
It was oriented with the seam facing the front of the Y axis.
I will try a cube as you suggested.

@SIam What would this help disambiguate? Would it indicate if it is over-extruding in general or just at certain points?
-
As the spiralized without prime looks good for me, why are you using prime?
-
the cylinder looks good so far
your extruder runs smooth without any clicking noise? -
It does make a soft noise when it is retracting, but i wouldn't describe it as clicking. More like gears turning.
Since I haven't had a Titan before, i wasn't sure what to expect from it. I have it set at:
400 jerk mm/min
5000 speed mm/min
2000 accDIY, i was testing prime in the regular print also, so I thought I would just point out the conditions of the two different tests.

@RedMachine
Your jerk and acc is very low. On my BMG I use much higher values. -
@DIY-O-Sphere
What are your settings?
So I can know a range to start messing with. -
@RedMachine
Depends on the size of the motor.
In you case I would take the values of Phaedrux. They were pretty similar to mine (Pancake BMG direct) Currently I'm back on a bowden setup with a bigger motor.

You also can increase your max. speed. The linked value is very high and only nessary for high speed printing. I would set that to 8000 mm/min -
@RedMachine
From that base you can try to increase jerk. But at some point your extruder will start skipping. -
it's 1.8, but I think they are similar. 17hs08-1004s.
Thanks for the link, I missed him saying that in that thread.
