Y-adapter and setting hotend temps

[clytle374]

I'm on a V2, but being the y-adapter kit is for the V3 and everything else is equal, I'm posting it here.

I can set the temp on the machine and then shut the other extruder off. At this point switching between T0 and T1 sets the active called temp to the value for that extruder. switched back and forth several time.

Code: Select all

 M104 S240 T0 ; set temperature
M104 S220 T1 ; set temperature 

and

Code: Select all

M109 S240 T0 ; set temperature and wait for it to be reached
M109 S220 T1 ; set temperature and wait for it to be reached

Neither of these work to set the temp of T1.

What is the proper way to handle this? Can't figure out how to get Slic3r to do it, but in reality the firmware should... And nearly does

Thanks

I'm assuming you're using the newest firmware? If so, remove the tool commands from the end of your M104/M109 commands. Since both extruders are using the same hot end, setting the temperatures independently is problematic - Have it just state the desired temperature after each tool change and it'll work.

Yes on the newest firmware...
I figured that changing back and fourth 20 degrees or so would happen easy enough. Unless it's too low for the new material to flow.

Just seems odd that you can trick it into remembering separate values and t0 and t1 calls handle it.

Thanks for the help
