Extruder Not waiting for Standby timeout before going into Standby
Hi Again,
First of all wanted to say thank you again for your work on this, your idea to add a debug macro command was a great idea, really helps troubleshoot. I found another issue, this one is impacting me. No matter what I change the standby timeout to the extruder goes into standby right away. In trying to troubleshoot this it looks like form the logs that KTC_TOOL script is changing the extruder it to standby twice and then then once more in the _TOOL_DROPOFF_START script. For the second and third time it thinks that the extruder was not active and puts it straight into standby. I can remove the M568 in the _TOOL_DROPOFF_START (using scripts from your config) but have not been able to trace why the KCT_TOOL script is doing it twice. Log showing this:

Still troubleshooting this one, have not been able to trace why it is doing it twice, but have created a quick work around for now by commenting out set_timer_to_standby(NOW) in line 346 of ktc_heater.py.
Thank you for finding this. I will not be able to debug it until I get back home to my machine after the holidays. Happy you found a bypass. I didn't experience any such problems. Regarss, Abdrei
Just in case someone is still struggling with this issue, here's my temporary solution: Call DESELECT_TOOL before selecting the next tool.
I changed my T* macro to this so nothing extra has to be changed on the slicer or Mainsail interface: [gcode_macro T0] gcode: KTC_DESELECT_ALL KTC_T0 [gcode_macro T1] gcode: KTC_DESELECT_ALL KTC_T1
It seems that the heater_active_to_standby_delay is ignored due to Heater state is set to STANDBY without being ACTIVE first, which normally happens when the KTC_TOOL_SET_TEMPERATURE CHNG_STATE=1 is ran TWICE. Somehow going straightly from KTC_T0 to KTC_T1 would set the standby state of previous tool for 2 times in a row, which set the standby timer to 0.1s causing the heater to drop temperature (almost) immediately. Calling KTC_DESELECT_ALL before KTC_T*, however, won't trigger this bug and the standby timer got preserved.
