Update 11/03/2020
Added post-processor properties
- Optional layer change macro property. Executes a macro at start of each layer. Insert full path to macro as per M98 in post-processing properties window. Useful for timelapses etc.
- Minimum layer to run layer change macro, default 2. Layer change macro will execute at the start of this layer and every layer thereafter.
- Optional post-heat macro property. Executes a macro after heating but before print start. Insert full path to macro as per M98 in post-processing properties window. Useful for additional wipe or purge routines.
@gtj0 Unfortunately adding H1 to M0 is pointless at the moment, the heaters are turned off automatically by the toolpath generator at the end of the routine which can't be edited. Much like the purge line. There may be a workaround, I'll keep at it.
-
@littlehobbyshop Great update! I guess we can always turn the heaters back on in a stop script if needed. When conditional gcode gets to the point where we can set global variables via Mcodes, maybe there can be an option to pass things like that to the stop script (and other) scripts.

Is the expectation that it will result in better prints because it has the exact model rather than STL approximation?
-
@zapta You would think so but it's gonna take some work to figure out whether that's the case or not.
-
@zapta The big difference will hopefully come on curves. At the moment Fusion is breaking up curves into linear segments for FFF printing, much like you would get from an STL. Hopefully this will change in future as Fusion already has proper curve generation in the machining CAM. I'm yet to work out whether this is limited by the toolpath generation or whether it's something to do with the machine definition, documentation is non-existent right now.

UPDATE 12/03/2020
Workaround for disabling generated toolpath control of extruder and bed heaters. Enable Heater Control (Default: Yes) decides whether the slicer should include commands to control initial warmup of the extruder and bed, followed by shut off at completion of the print. Enable for simplicity, disable if you want to use other methods (eg. the filament system) to control extruder and bed temps. The post-heat macro property remains but is not necessary if heater control is disabled, in that case any methods that would otherwise go here can be moved to start.g.
Re-instated M0 H1 at end of print
Right now this is probably as far as I can go functionality wise. the idea was always to strip out any excess gcode commands and so far that has been done so it will stay as it is until the next Fusion update or they release more documentation.

UPDATE 12/03/2020
Wait, IT'S DECEMBER ALREADY???
-
I have never been able to understand why there are two different notations for dates.
Personally I think it should be 2020/3/12 -
Full ISO please...
2020-03-12T16:47:31-06:00 -
My bad
Apologies all around! -
We should just count milliseconds since the big bang if we wanna get precise.
-
Would we be able to do that with 64 bits or do we need to go with 128 bits instead ?
Maybe we should all standardize on the 'Stardate' system ?
-
Someone stretching his neck to create an optimal RRF post for F360, and you guys start a date notation discussion?

We paid the man his upvotes, let us have some fun.

OK, granted

Hah. No. I started watching on my phone then switched to a browser. I'll edit.

Looks like Joel did one as well...

Nice!
For best compatibility, you might want to add
H1to theM0to keep the heaters on. This way cancel.g or stop.g can decide whether to turn them off or not.Not necessary, the heaters are only turned off if the stop.g or cancel.g file is not found. I may remove the H1 option in a future release.
