Unexpected M568 Results

[DonStauffer]

If tool 1 is active but turned off and M568 sets temperatures for tool 0 and turns it off, then a T0 command activates tool 0, tool 1 unexpectedly goes to standby rather than staying off. This seems like logical behavior if tool 1 was active, but not if it's off. I assume it's based on tool 1 being "active" despite being turned off, because it was the last one activated.

T1 ; Activate tool 1
M568 P1 A0 ; Tool 1 heater off

M568 P0 R145 S245 A0 ; Set tool 0 temps to 145 & 245, heater off
T0 ; Activate tool 0

@DonStauffer I guess there are default values for standby temperature?
You'd have to overwrite it to "0" in your tool1 definition to be off or explicitly do that in the toolchange macros.

That's correct. Currently, when a tool is freed, RRF always put it into standby. There is perhaps a case for not doing this if the tool was off.

@dc42 I can work around it. It just took me a while to figure out what was happening. I ended up with 2 tools heating at the same time unexpectedly.
