CURA 15.04.05 HEAD COLLISION ON PRINTING ONE AT TIME MULTIPLE OBJECTS

Recommended Posts

I realized that cura 15.04.05 dooes not compute properly printer head moving in multipe objects - print one at time mode.

after completing an object, the z axis starts to move before the head is positioned in a safe location bringing to the collision with the previous object with unpleasant consequences.

previous versions was ok

example:

 

old versions --->ok

on Z45.900

G1 F3000 X147.358 Y26.018 E3958.01775

M107

G92 E0

G10

--- first object completed

G0 F12000 X147.358 Y26.018 Z50.881 --- raise head

G0 X75.637 Y87.631 ---- move x y in a safe position without moving z

;Layer count: 229

;LAYER:0

G0 X79.193 Y89.349 Z0.300 --- move x y and go to z 0

 

cura 15.04.05 ---> CRASH

on Z45.900

G1 F3000 X86.556 Y55.160 E6226.79748

M107

G92 E0

G10

--- first object completed

G0 F9000 X86.556 Y55.160 Z50.881 --- raise head without moving x and y

;Layer count: 230

;LAYER: 0

G0 X75.375 Y88.105 Z0.300 --- moving x and y togheter z axis!! printer head crash on the previous object!!!!

this is a bug that, in addition to damaging the printed objects, could also lead to damage to the printer!

thanx

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
