Issue with slicing

[Federico_T 0]

Hi I'm Federico,

I have a home made 3D printer, it's a core XY with a trapeziodal scre axis. The X and Y axes are move by a 7x7 0.8 mm steal rope and it has a creality extruder and hoted.

First of all I have to say that it used to print just fine but since Cura 5.0.0 my 3d printer no longer can print correctly on the Z axis. 

Every layer is slightly offset on the X and Y coordinates, it's a regular things that make the print printed on a about 60° angle form the build plate (as in the photo). I'm pretty sure that the issue it isn't related with the printer its self simply because the offset is constant throug the whole print. 

I noticed this problem when Cura 5.0.0 was relese and I continued to use the older version, then I added the bltouch sensor and I tried to use Cura 5.1.0 (I don't remember exactly) and luckily it worked for a couple of month. Then the issue start to appear again.

Untill now I try to: 

- tune the mechanic part

- reflash the firmware

- use older version of Cura (4.8.0 and 4.13.1) 

- use the latest version of Cura (5.2.2)

- use another stl file

- use prusa slicer (2.5.0 with arachne enable and disable)

 

In my opinion the engine that create the path for the extruder it's causing this issue. 

Any suggestion is welcome I'll happy to share other informtion if it's needed. 

 

Sorry for my bad english .
