@modl Does your resurrect-prologue.g file home Z? Or do you continue the print without homing Z?

The resurrect.g file includes an absolute M291 command to restore the original babystepping. That should work if the resurrect-prologue.g file homes Z. If it doesn't home Z, then it would be better to set babystepping to zero.

@chrishamm Thank you very much I'll stick with the G4 in the macro then. Will report if the event occurs

So I should have looked closer at the gcode before but it's actually quite messy so there could be this

Anyway I setup a wipe tower for both extruders. Created a 40mm wide, .4mm thick pipe, sliced it in the place i want the wiping to happen with the two extruders separately, extracted the gcode for 1 layer for each, deleting the G1 Zx.xx instructions, and created a macro called wipetower.g executed on every tool changes. In the macro depending on the tool selected it will extrude the corresponding circles (2 lines wide for .2mm nozzle and 1 for .4mm) at the designated place.
Will test and report

I also redesigned the cooling system that i was not really happy with, should be much better

I'll definitely look into having smoother walls for the organic support but I don't think we have much control over this...

@modl thanks for sharing that.

In the future I have it in mind to be able to use the second file reader to run a simulation of the print in parallel with but ahead of the actual print. The simulation would be able to warn about upcoming tool changes, allowing for automatic tool preheat.

@Phaedrux Thank you for your reply, I haven't tested that it's a good idea, will do after the current print is finished (about 12days...)

@chrishamm thank you for your reply. They are custom macros in 0:/macros folder that i experiment with (and somtimes they fail 😅) , not system macros

@T3P3Tony closing this issue, please comment once tested.

@dc42 Thank you, it sounds plausible. I'll try to write some code for deamon.g to mitigate the null case (like store the last available correct value in a global and use that instead)

@dc42 Hello ! I found the place in gcode.cpp where i could add a G11 or a G1 E10 at the end of ressurect.g . Not sure I want to go down the path of compiling a custom firmware though, but:
Would this work ? : adding

// Now unretract filament buf.catf("G11");

after

// Now move down to the correct Z height buf.catf("\nG0 F6000 Z%.3f\n", (double)pauseRestorePoint.moveCoords[Z_AXIS]);

in

if (ok) { // Build the commands to restore the head position. These assume that we are working in mm. // Start with a vertical move to 2mm above the final Z position buf.printf("G0 F6000 Z%.3f\n", (double)(pauseRestorePoint.moveCoords[Z_AXIS] + 2.0)); // Now set all the other axes buf.cat("G0 F6000"); for (size_t axis = 0; axis < numVisibleAxes; ++axis) { if (axis != Z_AXIS) { buf.catf(" %c%.3f", axisLetters[axis], (double)pauseRestorePoint.moveCoords[axis]); } } // Now move down to the correct Z height buf.catf("\nG0 F6000 Z%.3f\n", (double)pauseRestorePoint.moveCoords[Z_AXIS]); // Set the feed rate buf.catf("G1 F%.1f", (double)InverseConvertSpeedToMmPerMin(pauseRestorePoint.feedRate));

@modl I'm glad you got it working. I'll mark this as solved, but you can revert it if you need to.

@droftarts thank you for your response !

Yes i have double checked the orientation, accelero +x = machine +x ; accelero +z = machine -y

M593 P parameter is temporary i was playing around with it, but 66hz is what i get all the time

@FreakOnLeash Probably best to start a new thread and share some more information about your setup.

@modl fantastic!
