    • RE: Z moving twice distance - Was working - now it's double

      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?

    • RE: Z moving twice distance - Was working - now it's double

      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

    • Z moving twice distance - Was working - now it's double

      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!

    • RE: bulge after z seam when printing outer layer first

      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.

    • RE: bulge after z seam when printing outer layer first

      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.

    • RE: bulge after z seam when printing outer layer first

      @SIam What would this help disambiguate? Would it indicate if it is over-extruding in general or just at certain points?

    • RE: bulge after z seam when printing outer layer first

      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.
