SHAPER_CALIBRATE internal error after update

General Discussion

Basic Information:

Printer Model: Voron 2.4
MCU / Printerboard: BTT M8P / EBB 2209 RP2040
Host / SBC: BTT CB1
klippy.log klippy.log (3.3 MB)

Describe your issue:

I updated from v0.13.0-87-gfd55dd9e to v0.13.0-110-g1af219fa to a avoid this bug but with the new version SHAPER_CALIBRATE no longer works. The printer moves to the XY position and then Klipper crashes immediately.

Downgrading Klipper to the previous version (without reflashing theM MCUs, so they still run 110) solves this issue, so this seems to me like a bug recently introduced.

Commit 64d6f110a works fine, it breaks with 307c03e

Update to latest Git. Should be fixed via resonance_tester: Fix typo · Klipper3d/klipper@ed36041 · GitHub
