RESUME - Option to move to XY first then lower to Z

[PhilBaz]

Requested feature:

The current implementation of RESUME (along with park_pause_spot) moves the tool head diagonally (in Z) to the XYZ position where the toolhead will resume.

This caused a nozzle catch and layer shift for me once or twice.

I think it would be ideal to at least have an option to move first to XY position then down to Z to minimize the chance of any nozzle catch. the implementation could have its own Z Height parameter (above the resume position) or use the Z lift height implemented for pause.

Just as it makes sense to lift on pause it makes sense to unlift on resume.

Solves the following problem:

Nozzle catch/crash/layershift when hitting a curled edge or something else.

Additional information:

Thank you for everything you do!

This have nothing Todo with mainsail. Mainsail just send the macro/gcode name. The rest is your Klipper config.

The position can be set in/with your mainsail.cfg, but resume is mostly a Klipper thing.

@meteyou

It has as much to do with mainsail as the 'variable_custom_park_dz' Z lift parameter in the 'Client variable' control panel for the mainsail.cfg, no?

It has about the same amount as most of the functions in the 'Client variable' macro, no?

[meteyou]

Both have nothing Todo with mainsail as Webinterface. It only send "PAUSE" or "RESUME" via Moonraker to Klipper. Nothing more.

Do you happen to know who establishes the _TOOLHEAD_PARK_PAUSE_CANCEL behaviour? Maybe I should get in touch with them?

@meteyou Sorry, nevermind.....just saw there was a credit at the top.
