Confused with the temperature of active and standby

Yes, that's the reason - you need the tpost macro files as described by dc42. My own tpre/tfree macros are empty, but moving the head away when a tool change occurs probably won't hurt (and may be a good idea when printing PLA).

You need at least some of the tpre, tpost and tfree files, to make the printer wait while the new active nozzle is heating up. I suggest these:

; tpre0.g
; Put G/M Codes in here to run when Tool 0 is freed
G1 X1 Y205 F6000

; tpost0.g
; Put G/M Codes in here to run after Tool 0 is selected
M116 P0

; tpre1.g
; Put G/M Codes in here to run when Tool 1 is freed
G1 X1 Y205 F6000

; tpost1.g
; Put G/M Codes in here to run after Tool 1 is selected
M116 P1

The commands in the tpre files just move the head out of the way. The commands in the tpost files wait for the new active hot end to reach temperature.

You can leave the tfree files empty.

Everything works well.however,
The temperature starts getting up(160 to 200) when tool changes.The extrude still feeds the filament during the temperature is getting up.it can not feeds the filament because the temperture is uping to 200 but not get to 200.Is this a problem of tfree,tpre and tpost files.I delete it all.

Your tool configuration looks good to me, although I'm a bit surprised you don't set up a tool offset in your configuration.

What exactly happens when you send T0, heat up the first tool heater to at least 100C and perform a retraction move?

We need to know exactly what doesn't work: Are you unable to feed filament, extrude it or are you wondering why you can't pull it out of the extruder block by hand?

Are you referring to retraction moves? You must activate a tool before you can drive the assigned E motors. Can you post your config file?

OK,I mean the PLA can not pull out at the rising temperature of 160 up to 200.It still ran when the temperature is getting up.I delete the tfree,tpre and tpost files....

However,the temperature can not get up enough when the heater has changed.Then the heater get stuck.

Can you explain exactly what happens - in particular, what do you mean by "heater get stuck"?

Also, please post the contents of all your tfree, tpre and tpost files.

HEY,anyone who can answer my question?DC42,ZPL.Are you there?

Confused with the temperature of active and standby

I use two heaters, E1 and E0.Active T is 200 and standby T is 160.However,the temperature can not get up enough when the heater has changed.Then the heater get stuck.
I must make some mistakes in the configration.how to fix it?
