SOLVED Graber I3 Titan Aero Upgrade - Layer Problem

Hello Guys,

I have a Graber I3 (Prusa clone) with ramps 1.4 which I upgraded to use Titan Aero and BLTouch.

After upgrading I was not able to extrude the 100mm, so I had to raise the stepper voltage to 1.0v. Then I got the proper 100mm extrusion.

Now when I try to print, I see that the layers are not sticking to each other, it seems that the upper layer extrusion is to far from the previous layer printed.

Here is a example of that is happening

I'm using ABS as filament

My printer settings are:

Code:

#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 4000, 837 }
#define DEFAULT_MAX_FEEDRATE          { 500, 500, 2, 45 }
#define DEFAULT_MAX_ACCELERATION      { 3000, 3000, 15, 2000 }
#define DEFAULT_ACCELERATION          1200    // X, Y, Z and E acceleration for printing moves
#define DEFAULT_RETRACT_ACCELERATION  1200    // E acceleration for retracts
#define DEFAULT_TRAVEL_ACCELERATION   1200    // X, Y, Z acceleration for travel (non printing) moves
#define DEFAULT_XJERK                 10.0
#define DEFAULT_YJERK                 10.0
#define DEFAULT_ZJERK                  0.4
#define DEFAULT_EJERK                  5.0

My S3d settings are:

Code:

Nozzle Diameter: 0,4
Extrusion Multiplier: 1,00
Extrusion Width: 0,4

Retraction Distance: 1,5mm
Reatraction Speed: 1800,0 mm/min

Extruder Temperature: 240
Bed Temp: 100

Do you have any clue of what is going on?

 

Hi Old_Tafr

Thanks for helping me.

I followed the tutorials from E3D and Bltouch page, they are:

As I was trying to calibrate my e-steps and wasn't able to get it right, I found this guy that had similar problems with e-steps, so he raised the voltage to 1.0v, after that I got the

My Marlin Version is 1.1.8

I'm getting a video of the print to illustrate the problem

 

Hi

Here is a video of printing process. I noticed that after 3 layers things starts to get strange

I did a full review of BLTouch settings, and even lower the print speeds to check if it gets better

 

I found the problem, it was Z Axis step calibration.

I was working with the 4000 value, and now it is 1500.

Thank you guys
