[BUG] Second Object initial Layer to fast.

Post by derdigge »

Dear reader.

I faced a bug when printing 2 Objects in one slice. The gcode is attached.
The initial Layer height is 75% which is .3 mm in my case. My initial layerspeed is set to 5mm/s.
The second Object .3 layer is printed at 10mm/s. In the gcode see line 2467.
We are still at initial layer .3 but speed gets up to 10mm/s(F600).

I do not think that this is right. My version is latest stable 1.6.3

Thanks

The Gcode.

Hello everyone,

This is still an Issue. I digged deeper into this phenomena.

Here is the models screenshot:
https://www2.pic-upload.de/img/35750611/M1.png

So as you can see here the 3rd model has initial layer heigth 0.301, the others have 0.300.
In fact kisslicer behaves as 0.301 is a second layer.

So i tried to set "Joint" to true. This fixes the issue but we dont want joint as the tooltip allready mentioned.
What i am doing wrong?

EDIT: Just tested with Kisslice 2 Alpha and it is the same behavior.

Actually, there is a reason. You are using "adaptive" layer heights. The second model starts at layer 2, which is 1 micron higher than layer 1.

And that is the reason why "joint" resolves the issue.

But I agree with you that it's wrong and have already put in a fault report.

Hello Peter.

Thanks for paying attention to this issue. I really do love kisslicer.
I had no other issues so far. It produces beautiful prints.

Me too!

Unfortunately, development has been suspended for a few days. Hopefully Jonathan will be back soon. There's a few things for him to catch up with...

Having a similar problem with 1.6.3 alpha. Printing 2 copies of the same model works fine. If I load and slice 2 different models then the first layer of the first model prints at the expected speed, but the first layer of the second model prints much too fast.
