Multi-layer skirt option

Snapmaker Luban
1

I know Luban uses CuraEngine as back-end for its slicing operation. Usually, I print with skirt (sometimes raft) but I keep having the same issue. The single layer skirt sticks to the print sheet like glue and I keep wasting my time removing it. Just because there is only one layer of it. Not using a skirt clearly affects the first layer quality leaving me with no option but to scrap it off the hard way. I could slice with PrusaSlicer to have multiple layers of the skirt but this has other downsides. Like no tree supports for example. There actually exists an issue on their Github page regarding this:

But Ultimaker uses a glass print bed and has no intend to make life easier for others than their customers. Hence, I suggest/request to the Snapmaker team to take a proactive step in solving this issue.
Or am I the only one struggling with this?

  • I am having the same issue. Please help!
  • I have never had such an issue. Please put your efforts in something more useful.

As a work around, you can play with the first layer height. If Iā€™m using a skirt, Iā€™ll usually stick with the 0.3mm first layer height. If Iā€™m not, Iā€™ll make first layer height equal to layer height.

Why donā€™t you just change the skirt to more than 1? You can in both Cura and Luban.
Thatā€™s what I do. When I first started I turned it off, but have found it helpful to check my z-offset and it just seems to ā€˜prime the pumpā€™.
I generally use 3 unless itā€™s a really big model. Then I just go with 2.
Comes off much easier.

My current settings for skirt are:

  • Skirt line width: 0.4mm
  • Skirt speed: 18mm/s
  • Skirt acceleration: 1000mm/sĀ²
  • Skirt line count: 3
  • Skirt distance: 3mm
  • Skirt minimum length: 250mm

And I am having trouble to remove that skirt.

Then itā€™s probably not a skirt issue.
(I just use default btw)
Your z-offset is probably too close. Thatā€™s usually the cause when the adhesion is too great.
Or you can use glue stick.

Thank you for that hint. I will see if that improves it. However, the adhesion of the printed objects itself feels just right. Sticks well and comes off easily. Just the skirt remains tenaciously.
Also, this issue will manifold if I change to a smaller nozzle sizeā€¦

I tried setting a different z-offset with the Cura ā€œZ Offset Settingā€ plugin by adding 0.05mm. This worked quite well for the skirt but resulted in less adhesion for the printed object itself, which was quite undesirable. I will try to reduce the flow rate for the skirt next to see if that works better.

Reducing the flow rate for the skirt made things worse because the printed skirt gets even thinner and thus harder to remove. Too bad :frowning:
I really hope there will be a multi-layer skirt option in Cura like in PrusaSlicer in the future.

I have read this issue carefully. Snapmaker Luban does not support multi-layers skirt now.

I will forward this request to our software developer @parachvte , and he will looking into this issue.
