New P1S owner. I’ve tried running some prints using PLA and PETG and have ran into a recurring issue which is replicated in both BAMBU Lab and Orca Slicer.
As hopefully obvious in the picture, edges can be rounded between 0.5-3mm and there’s an ugly step pattern in the Z axis.
I’ve tried slowing the prints down and reducing the jerk/ acceleration settings with only minor improvements.
I’m guessing because the issue is replicated in both slicers there may be a mechanical problem. Any thoughts?
Welcome! Have you calibrated your flow dynamics for each type of filament? The values you get from this calibration need to be entered for each AMS slot or external spool in the device tab of Bambu Studio. (If you calibrate via Bambu Studio, it will automatically set these values for you.)
Sure thing, no worries. The K value varies for each filament and loads up when you begin printing. (This isn’t something your slicer handles.) The default values usually work well, but they can vary, especially if your PETG is moist. Just fire up Bambu Studio, click on ‘Calibration’ at the top of the window, choose ‘Flow Dynamics’, then ‘Manual Calibration’. Select your options and filament, and hit ‘Calibrate’. The following screen will guide you through the process.
It’s also wise to dry PETG before printing, particularly if it’s stored on an external spool holder. If you don’t have a filament dryer, you can place the spool on your heatbed and set it to around 60 degrees to dry it out.
i would agree, but the dryness of the filament shouldn’t manifest itself in radiused edges surely? I’ve ran the K-test so will adjust and re-run, but the number it’s kicking out is very similar to the one in slicer already
A wrong K-value can result in round edges. Sometimes, seeing the correct value with the line test is hard. You could also switch the test method from line to pattern.
