First T0 in gcode, does not work
-
Do you have a T0 command at the end of config.g? The online configurator gives you the option of inserting one.
-
I just checked, and no, neither in homeall.g
-
I will test tonight by putting a sound in the command tpost0.g
And I will raise everything, as I will see. -
it's the M109 S225 T0 the offender
-
he selects me the tool, but not completely
-
@NicoLab28 so a tool needs to be selected so you can heat the Hotend, but, it's too cold to extrude. So my work around is to just let the Hotend heat up at the start then what I do is this
Start code example;
Heat up Hotend...
T-1 P0
T0
Start printing....I always have a T-1 in my end gcode so the machine is always unloaded when starting

For compatibility with slicers that don't select a tool before heating it (i.e. most of them), if M109 is used with no tool selected then RRF selects the tool. So M109 S225 T0 run with no tool selected should be equivalent to T0 followed by M109 S225 T0. It should still run the tool change files exactly as if you had used the T0 command explicitly - assuming that all axes are flagged as having been homed. But of course the tool won't be hot when the tool change files are run, so commands to extrude or retract filament will probably fail.

Thank you gavatron and DC42,
The problem with the T-1 is that if there is a filament loaded at the beginning of the print, it will unload it.
For now, I load my tool before,.There is a method / trick for heating the hotend without selecting a tool?
No doubt the use of
G10 Rxx Sxx
T0
in the print fileM116 at the beginning of tpost # .g (which I already do)
-
That's why I always start unloaded, then load before each print. Much easier

You can use T-1 P0 to deselect the tool without running the tool change files, if you don't need any part of the free file run.

Use T0 P0 to select tool 0 without running any tool change files, then you can heat it.
