[Necessary enhancements in Cura / Eperimental / Wipe Nozzle)]

Hello gr5, thanks for your guidance.
I created a new problem in GitHub.

[Wipe: Additional cleaning at the beginning and end of the entire print]

 

Cleaning the nozzle is very important with PETG.
Otherwise the filament will stick to the nozzle. In the case of larger parts, printing will then fail!

 

 

For Cura / Experimental / Wipe please add these two options:

 

1. Additional cleaning at the start
Should be executed after the "Start G-Code".

 

2. Additional cleaning at the end
Should be executed before the "End G-Code".

 

 

Thank you

That is correct. 

My day-long attempts with different parameters could not prevent the nozzle from sticking with somewhat larger parts!  With PETG, the only thing left is the automatic repeated cleaning of the nozzle, even in between.

I use the 3D printer "anycubic-predator":

The filament is PETG. That doesn't mean warping. However, after a while the nozzle sticks. Which unfortunately slowly but surely destroys the part!
A cleaning brush cannot be attached to the X-axis of the delta printer. Further optional input values are required (shown in red in the picture):
1. additionally required: Y absolute
2. additionally required: Z absolute
This gives an absolute starting position X-Y-Z for the wipe move (shown in yellow in the picture).

 

Avoid collisions between the nozzle and the printed part: 

If the part to be printed plus "Wipe Z Hope Height" is higher than the entered Z value, cleaning should no longer be carried out.

However, cleaning should be carried out before it is exceeded.

 

I think these enhancements are important for users of delta printers.

Cartesian 3D printers also require an additional axis (X or Y).

 

What is your opinion?
