... but OTOH if you halt the move queue immediately, you are likely to get missed steps (and hence the incorrect position when you resume) if you interrupt the move queue on a move that doesn't have a near-zero end speed. I'll revisit this when I have finished my other changes to the Move code.

Just wanted to say that I implemented zpl's pause/resume macros in my recent release, although I haven't had tie to test them yet. My pause feature isn't as instant as zpl's because it waits for the move queue to empty; but OTOH if you halt the move queue immediately, you are likely to get missed steps (and hence the incorrect position when you resume) if you interrupt the move queue on a move that doesn't have a near-zero end speed. I'll revisit this when I have finished my other changes to the Move code.

1. Regarding the fan on/off, there is currently no support in the firmware to switch the fan off while remembering the current setting, or to switch it on again at the previously remembered setting. I suggest we extend M106 parameter to support an additional R parameter (not P because that would logically be used to select the fan number if there is more than one). M106 R0 would turn the fan off but remember the PWM value. M106 R0 Sxxx would set the remembered PWM value to xxx but turn the fan off. M106 R1 would turn the fan on at the remembered value. M106 R1 Sxxx would behave just like M105 Sxxx. As you are using zpl's firmware, I'll leave him to implement this, or something like it.

2. In order to handle the renumbering of tools from slic3r's T0, T1, T2 to T1, T2, T3, I added an option to the M563 command. You probably have command M563 S1 in your custom start gcode to renumber the tools. But unless you define tool 3, then the printer will do exactly as you describe when trying to print using tool 3. Why do you think slic3r's tool 2 should be mapped to T1? You could add another M563 command in config.g to define tool 3 as a copy of tool 1 if you wish. There is a possibility that the active and standby temperatures might get confused, but since the old tool is set to standby before the new tool is set to active, I suspect it will work OK.

The traffic cone I downloaded from thingyverse here [www.thingiverse.com] has 5 bands but the STL files are for just 2 extruders.
