Macros. Ideas, suggestions, tips and tricks

There isn't a gcode in RRF to wait for user action, but it sounds like a good idea to me. Is there an existing gcode that fits the bill? If not, should it be a new gcode, or just an option on M117?

Hugues

An option to M117 should work perfectly in case it show the message in the front layer (in macro layout)of the paneldue and not in the console layout/tab.
It could be really cool to implant this, it's open some user sequence in macro possibility.

Thanks !

Wouldn't using M577 and a switch on one of the E endstops work?

I didn't try but it should work. This switch or button can also have a pause function like PRZ did.
But it will be nice to have a virtual button and associated text on screen, it's more ergonomic ! (and less wire ! )

A quick hack I use in both my slicer epilogue and in a macro file:

M140 S-273
M109 S150
M104 S-273
M81

This shuts off the heated bed, waits for the hot end to cool down to 150 C, then shuts off the 12V power (including, in particular, the hot end fan).

My prints also start with:

G1 X60 Y70 Z15 F6000
G1 X70 Y70 Z5
G1 X65 Y90 Z5
G1 X65 Y70 Z5
G1 X60 Y90 Z5
G1 X60 Y70 Z5
G1 X60 Y70 Z15
G1 X0 Y0 Z50

This makes the nozzle scrub itself on the toothbrush ziptied to the frame of my Mini Kossel. A toothbrush is definitely not ideal; now that I have a hardened nozzle I should probably switch to a wire brush or something.

I'm using a bedcheck.g file containing

[[language]]
;bed level check

G30 P0 X-100 Y-60 Z-99999		; X tower
G30 P1 X100 Y-60 Z-99999		; Y tower
G30 P2 X0 Y100 Z-99999	S-1		; Z tower

G1 X0 Y0 Z100 F10000

Which I run using M98 Pbedcheck.g after G32 it probes the tower bases as that where my bed supports are.

I've added couple of new ones. Since PLA and PETG run at different temps, the z probe offset is slightly different between them.

For example the PETG Offset has:
G31 P500 X0 Y12 Z1.6 ; increase Z to get closer to bed

The PLA Offset macro has a different Z.

Is this implemented yet? I really could use this right now for a bed leveling macro… I would like to move the head around to 4 points and wait for user input at each point.

It's not implemented yet. Perhaps it should be M226 with a parameter that means "don't run pause.g or resume.g"?

That sounds like it would work perfectly….. right now I have 4 different macros for each point.... trying to make this simple for my kids. A single macro that pauses at each point where they can adjust the leveling screw then hit confirm on the paneldue would be perfect.
