Hi Makers,
We’re collecting the issues you’ve encountered when using Luban V4.5 and trying to solve them asap. Please record the problems in this topic and I will sort them out and update the corresponding solution (once we figure it out) in the main post. Also, you can search for similar issues and solutions in this thread first if you have problems with Luban V4.5.
Appreciate any feedback!
Issue 1: Have chosen the 10W Laser Module in Luban, but it still shows 1600mW in Machine Settings.
Solution: It’s UI bug. If you choose 10W once, the relative settings will take effect immediately even if it still shows not as so. Will be solved in the next update.
Issue 2: The nozzles didn’t heat up after the printing starts with the G-code generated by Luban.
Solution: The nozzle will be heated after the bed heats up (They previously heat up simultaneously). Will be solved in the next update.
Issue 3: The support settings in the default Precise & Strong configuration is Normal.
Solution: It should be None. Bug. Will be solved in the next update.
Issue 4: Failed to manually delete the support structures that are generated automatically.
Solution: Will be solved in the next update.
Issue 5: Failed to slice the test model (vase) and stuck at 10% during the previewing.
Solution: You could skip the Beginner’s Guide process. Will be solved in the next update.
Issue 6: The prime tower disappears after first copying the model and then undoing the copying.
Solution: You could skip the Beginner’s Guide process. Will be solved in the next update.
Issue 7: The imported CNC or Laser project loses custom configurations and doesn’t show preset configurations.
Solution: Will be solved in the next update.
Issue 8: Luban crashes during slicing.
Solution: Luban v4.5 doesn’t support macOS 10.13/10.14 and older versions. Please check this first. To download previous versions of Luban, visit our Github Release Page. If you are a dual-extruder user while your OS is not supported by Luban 4.5, you could try other slicers. We’ll try to collect profiles of other slicers for the dual-extruder posted by others in the forum and create a collection topic in the future.
Issue 9: Luban v4.4 or older versions cannot update inside the software (via the updates notification window).
Solution: It’s a known issue on some Macs. If this happens, download the v4.5 installer from our Github Release Page.
Issue 10: Couldn’t use Luban v4.5, so re-install Luban v4.4. But this error message keeps popping up for whatever the model: “the slicing failed because the model is too small.”
Solution: It could be some configuration file errors. You could try these steps to solve it:
- Find the configuration file in the following path and back it up somewhere else.
- Windows OS: C:\Users\admin\AppData\Roaming\snapmaker-luban\snapmaker-recover
- macOS: /Users/admin/Library/Application Support/snapmaker-luban/snapmaker-recover
Note: Replace admin in the path with your username.
-
Delete the whole snapmaker-luban folder (the one in the path above) .
-
Reinstall Luban v4.4.
Issue 11: Abnormal configurations, like missing entrys for the heated bed temp. in settings
Solution: You could try these steps to solve it:
-
On Luban, click Settings > Backup Config, and then click Open Config Folder.
-
Delete the configuration folder that you think is abnormal (in your case, it’s the printing folder).
-
Re-launch Luban and check if the problem persists (Luban will re-create the normal configuration files).
