@Jade This photo may be difficult to make out, but there is significant defect in the top surface layer of the print on the right. This defect exists ONLY when the VC is turned ON, even after full tuning. Both parts are the exact same .gcode file, but the left part is with the VC off. The part on the right looks and feels like the lines’ widths have been heavily increased to the point of leaving gaps between the lines and are not following the slicer settings. I am still testing this to see if I can figure out exactly what is causing it, and will share a similar .gcode file that does the same thing, but I understand that when the VC is on it uses a significantly different linear advance; perhaps that has something to do with it? ![PXL_20241207_002502185](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/3/b/3b84be7355ba363280679d76d77e4b58b705ef68.jpeg) ---

I think it’s more dynamic and this could cause underextrusion like seen in your picture. Is it really simply turned off left and turned on right with the same firmware? - Wondering about such a big affect in those short movements… I have seen problematic hotend temperature behavior in the past when printing “too” fast, do you see any temperature drop while printing? ---

Well, I reverted back to non-VC firmware v1.20.3 to run a test print for troubleshooting, then re-installed VC firmware v2.3.1, and now I can’t get the problem to re-produce. The VC firmware also calibrated perfectly at the default freq setting (~59Hz) using both EI and MZV shapers, where before it calibrated at around 18. So I am inclined to believe that this may have just been a transient bug with the initial install. I can’t remember what exact process was the first time, but this time I know I made sure to power cycle the machine both after installing the firmware, and after turning on VC. Now printing with wall speed 100, travel speed 120, top surface speed 50, and accels 2k all-around, getting nearly perfect prints. The only defects I see now are very slight pinholes at the edges of my top layers that I believe are caused by linear advance, since they are present when using 2k accel, but not at 1k. Is linear advance still user/slicer-adjustable when the VC firmware is installed and the VC is turned on? ---

Just a thought… I have installed the VC v2.3.1 firmware with the dual extruder and things seem to be going well. However I’m not sure I know what settings to actually change. For instance if I leave acceleration and jerk control unchecked in Cura 5.9 the results are faster than if I enter 3000 or 2000 in acceleration. Also I have no idea what jerk control settings to enter. Am I being stupid and these are all available somewhere I can’t find? ---

If you connect to your printer over a terminal, the marlin settings could be found in the respond of M503. ---

I mean more that I can’t find a guide to what cura settings to change for the VC firmware. It seems to be working but I am kinda flying blind ---

You can see the firmware limits in the M503 respond. Depending on your toolhead it could be different. Depending on your model it would be necessary to adjust your slicer settings anyway. 120mm/s speed 3000mm/s² acceleration (if I remember correctly) Here is the mother topic and some settings are written in the test section: > [@Vibration Compensation Firmware Open Beta for 2.0 Series (A/AT/F Models)](https://forum.snapmaker.com/t/vibration-compensation-firmware-open-beta-for-2-0-series-a-at-f-models/35729/121): > > There are built in profiles in Orca… Use those.

What else did you find? Any new problem or result? How are your printings? Improved? Decreased? Can you share some pictures? I am looking to start testing this! ---

All is as stated in my most recent previous post. There have been no changes since then. ---

Can someone shed a light here? Please see the attached picture… after I did update the system tune it and start printing I am having these lines that I don’t know how to call them… the filament are dried all is in its place but I am feeling that something is going on here… ![IMG_20250624_193413](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/a/b/ab68227cc48c8ae126ed2ac8bc0a069e191f1b89.jpeg) ---

I think this is a feeding error, maybe your filament got caught or tangled and the nozzle was rising a short time? ---

You were not out of the reality… it was feed but at the same time was caused by low flow… I did tune up the flow and linear advance again and its not there anymore…
