      What setting are you using for extrusion rate/speed?

      Im having problem with too much extrusion and extruder is eating away fillament then not moving because of a divet.

      I bumped my m92 from E1025 to E700.

      heres my settings;
      ; Drives
      M569 P0 S0 ; Drive 0 goes backwards
      M569 P1 S0 ; Drive 1 goes backwards
      M569 P2 S0 ; Drive 2 goes backwards
      M569 P3 S1 ; Drive 3 goes backwards
      M671 X421:-111.5 Y162:162 S5 ; leadscrews at mid left, and mid right
      M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
      M92 X80.00 Y80.00 Z400.00 E700 ;E1025 ; Set steps per mm
      M566 X600.00 Y600.00 Z12.00 E120.00 ; Set maximum instantaneous speed changes (mm/min)
      ;M203 X9000.00 Y9000.00 Z180.00 E1500.00 ; -origional- Set maximum speeds (mm/min)
      M203 X12000.00 Y12000.00 Z800.00 E800.00 ; Set maximum speeds (mm/min)
      ;M201 X3000.00 Y3000.00 Z250.00 E12000.00 ; Set accelerations (mm/s^2)
      M201 X3000.00 Y3000.00 Z250.00 E700.00
      ;M906 X1250.00 Y1250.00 Z1250.00 E1250.00 I30 ; -origional- Set motor currents (mA) and motor idle factor in per cent
      M906 X800 Y800 Z800 E800 I30 ; Set motor currents (mA) and motor idle factor in per cent
      M84 S30


      See how thick the extrusion is and supports are suppose to be lot thinner.

        Not teaching you to suck eggs...
        What extruder are you using? Bowden or DD?
        Have you done all of the calibration? Feed and flow rates?
        This is the process I use https://mattshub.com/2017/04/19/extruder-calibration/
        I think its for Marlin fw, but the principle is the same.

        Voron 2.4 disassembled..... Waiting for the RailCore Mini....

            Titan with a 1.8 stepper should be in the 400-420 step range and double that if using a 0.9 degree stepper motor with the 16x microstepping. I have a bondtech BMG clone extruder on my ender 3 with a 0.9 degree pancake stepper motor...my esteps after calibration are 846.90. Also your acceleration is very high for your extruder which could also be causing issues. I have the max speed and acceleration for my extruder at 3000.

            M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
            M92 X80.00 Y80.00 Z400.00 E846.90 ; Set steps per mm (gregs wade was 604 steps)
            M566 X500.00 Y500.00 Z30.00 E600.00 ; Set maximum instantaneous speed changes (mm/min)
            M203 X10800.00 Y9000.00 Z300.00 E3000.00 ; Set maximum speeds (mm/min)
            M201 X1000.00 Y1000.00 Z500.00 E3000.00 ; Set accelerations (mm/s^2)
            M906 X700.00 Y700.00 Z700.00 E960.00 I30 ; Set motor currents (mA) and motor idle factor in per cent
            M84 S30

            EDIT: I see you commented out those high speeds...I didn't see the semi-colons at first glance.
