I'm following the steps here: https://docs.ratrig.com/commissioning-guides/v-core-3-1#skew-calibration(but I've also referenced https://www.klipper3d.org/Skew_Correction.html?q=) I printed everything, measured everything, and was able to use the SET_SKEW command and save the profile. In the printer.cfg, though, there's no place to put the variable_skew_profile item from Step 3. Just putting the [skew_correction] module in down by the USER OVERRIDES seems fine, but when I try to add in the variable_skew_profile part, Klipper crashes. What am I doing wrong? I'm now seeing the following in the SAVE_CONFIG section (which warns us not to touch): ## [skew_correction my_skew_profile] ## xy_skew = -0.004528173929946366 ## xz_skew = 0.0 ## yz_skew = 0.0 So, it looks like the data is there... I just don't know what to do in printer.cfg.
