Which does indeed = 400. So I either, suffering from some brain problems, changed it to 800 and assumed it was like that all along or did have something overriding it that I inadvertently changed. Not sure which is the better scenario.
Either way, thanks for your patience.
@infiniteloop
Yes, I just changed Z to 400 steps/mm it and it does appear to be correct with just a quick caliper check.
Am I wrong in thinking that a 8mm trap and 1.8 steppers at x16 should be 800 steps / mm?
I don't have an override at all.
I just confirmed that it happens even if i raise Z before I home.
homeall.g
G91 ; relative mode
G1 S2 Z10 F200 ; hop Z up 10
G1 S1 X-299 Y-299 F3000 ; move up to 240mm in the -X and -Y directions until the homing switches are triggered
G1 S2 X4 Y4 F600 ; move slowly 6mm in +X and +Y directions
G1 S1 X-10 Y-10 ; move up to 10mm in the -X and -Y directions until the homing switches are triggered
G90 ; back to absolute mode
G29 S2 ; disable mesh compensation
G1 X143.9 Y147.3 F2000 ; put probe at center of bed
G30 ; home z
G1 X-10 Y240 Z20 ; move tool out of way
G4 P1000 ; dwell a sec
G29 S1 ; enable compensation
What in the world have I done to cause this?
G1 Z20 puts me at 40mm from the build plate.
Prints were great, now everything is printing at 0.4mm layer height when it should be at 0.2. My 2cm cube is 2x2x4.
It homes just fine, and correctly reports Z0.
Using a standard 4 start 8mm trap screw and 1.8 steppers. 800 steps/mm is what I have been using for 3 weeks, I shouldn't have to set that to 400 with the exact same hardware....
I have no idea what I could have done to change this. I even swapped my board out with another duet card with the same result.
Thanks!

it's 1.8, but I think they are similar. 17hs08-1004s.
Thanks for the link, I missed him saying that in that thread.
@DIY-O-Sphere
What are your settings?
So I can know a range to start messing with.
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 acc
DIY, i was testing prime in the regular print also, so I thought I would just point out the conditions of the two different tests.
@SIam What would this help disambiguate? Would it indicate if it is over-extruding in general or just at certain points?
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.
It is a plane Cartesian that moves the gantry in the Z axis.
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.
I finished building my first machine a couple weeks ago and I am still trying to dial it in. It uses a Titan Aero. I am having a problem I can't seem to shake.
When I print the outer walls first using cura on a round object printing with PLA, the start of the move at the seam bulges, which gradually tapers off and looks good after about an 1/8 of the way through the turn.
The problem starts shortly after the base is done.
I have tried changing temp down to 185, pressure advance from 0 to 0.100, retraction up to 1.5, outer wall speed down to 10 and up to 50, cooling from 40-80%, minimum layer time up to 15s.
I think it must be overextruding at the start.
I am running out of ideas, any input would be greatly apprecitated.
Thanks!!
