Agenda

Unfortunately, our previous meeting go canceled, so this agenda is really full.

1. CI: Update to ubuntu-26.04 #4477 G7x new algo, and -ffp-contract=off project wise discussion.
2. Deprecation backport of mesa_modbus to 2.9 (mesa_modbus: deprecate in favor of hm2_modbus #4386). The 2.9 branch has everything in place to migrate. Can we delete the old mesa_modbus driver?
3. Migrate gscreen (and any other) to support s/ms on [DISPLAY]CYCLE_TIME or do we finally pick one? Minimally we need consistency (Unify [DISPLAY]CYCLE_TIME unit handling across GUIs #4424).
4. Timing for deprecation of old HAL API. The new 64-bit upgrade is being prepared. What is the minimum time for people to adapt before the old API is deleted? Or, should be just steam on and break the API asap?
5. PRs
   • homing.c: fix accumulation of HOME_OFFSETs when re-homing absolute encoders (2.9 backport) #4341
   • Orient.comp: Add modes with preceding homing to index #4343
   • G12.1, G13.1: select the kinematics type from G-code #4414
   • rs274ngc: back the rotary tool offset out of machine coordinates #4416
   • axis: jog increments follow the selected axis type (degrees vs linear) #4418 - needs additional discussion
   • build: make depclean remove the userspace dependency files too #4419 - are there blockers?
   • tp: rate-limit Ruckig plan-failure logging to once per segment #4420
   • (tp: allow tangent blending across near-collinear ABC and UVW motion #4421 needs feedback, I think)
   • tooldb: notify db_program of G10 tool offsets #4422 - approved by @grandixximo
   • 5axiskins, maxkins: take the tool length through a pin like every other rotary module #4431 - status? ready to merge
   • Fix spindle position-sync jitter and catch infeasible thread pitches #4441 - fixes Excessive jitter spindle position tracking #164 and Warn users that spindle is too fast in G33 / G95 #167 with about 10 year lag ;-)
   • kinematics: let a module report where the tool points #4455 - ready to merge
   • tp: keep the G33 sync origin on the spindle index #4453
   • include: move the exported headers into a directory of their own #4461 (maybe this needs to wait til old HAL API deprecation?)
   • interp: don't restore spindle speed on abort state restore #4473 (backport of interp: don't restore spindle speed on abort state restore #4467 - bug fix)
