[Reason for fail object]

Hello,

 

I printed 2 objects, but they fail. I used layer height 0.3 and infill 10% for the first image which is print raft, but on the opposite side print flat. I used layer height 0.15 and infill 20% for the second image, the printer seems get lost, but when I print next one with same program, it seems print good. So I just wandering anyone can tell me what is the reason could be cause those problem?

 

Thank you

[Able to use different layer height to 1 object]

Hello,

 

Is it possible to select first layer height 0.06, after that change layer height to 0.2. Because I only need face looks nice and beauty, after could be rough. If possible use 2 different layer height to 1 object, how to operate in the cura software?

 

Thanks

[what is the best printing speed]

Hello,

 

I print an object size: 180.0 x 118.0 x 6.9mm, but it takes 7h15min, is too long. In the cura sofeware shows print speed 70mm/s,Travel Jerk: 50mm/s. How can I increase the speed to print an object?  which speed should I change? (infill speed, wall speed, outer wall speed or inner wall speed...........)

 

Thanks
