Can´t print with extruder 2.
-
I´m printing without any problems with extruder 1 but everything freezes when trying to print with extruder 2.
The heater warms up as it should and starts printing but then everything freezes and print progress showen 100%.
It happens at different points depending on which g.code I´m running, it always does the startup code with homing, warms up bed and extruder etc., but then it freezes when doing movements.Could there be something wrong with my DuetWifi board or is it in my codes?
Have even switch places on my heaters/thermistors to rule out faulty components, they work as extruder 1 but not 2.
My g-codes works with T0 but when changing to T1 this happens.Firmware Version: 1.17c (2017-01-14)
Web Interface Version: HTML: 1.11, JS: 1.11a-dc42 -
Have a look at what is in your tool change g-codes (tfree0.g etc)
there could well be something in those that is causing an odd action. -
I deleted all my tool change files since I thought these were the problem and I now manually activate T1 then ran my g code,
doesn't help -
It sounds to me a bit like a problem with the tool definitions and/or active/standby temperature settings. Can you post your config.g file and also your slicer start gcode commands (or the first part of a gcode file up to and including the first few moves).

OK This is how it looks to me. In your config.g you have two tools, P0 and P1 and the operating and standby temperatures are set to 0 deg C for both tools (G10 P0 S0 R0 and the same for P1). That's fine because you don't want the tool to start heating as soon as you turn the machine on. Now in the start gcode you heat tool 1 (M109 S210 T1) but not tool 0. So when you switch to tool 0, it'll wait until it reaches 0 degC because that is what the operating (active) temperature is set to in your config.g and there isn't another command to override it.
So, what you need to do set the operating and standby temperatures for both tools in you start gcode. You could set them both the same i.e G10 P0 S210 R210 and G10 P1 S210 R210. If you do that, then when you change tools it will continue to print with no delay. However, you may find that you get filament oozing form the tool that isn't in use. So what most people do is set the standby temperature lower to (say 170) or whatever temperature you can use with no oozing. Then when you change tools, there will be a delay while the new tool heats up from standby (170) to active (210) then it will continue to print.
Finally, you should add G10 P0 S-273 R-273 (or just 0) and G10 P1 S-273 R-273 to your end gcode to reset the active and standby temperatures at the end of the print.

Just one more thing. I'm assuming you gcode file switches between T1 and T0. Not T1 and T2 because you haven't got a T2. By default the first tool in firmware is T0, the second T1, etc but many slicers use T1 for the first tool and T2 for the second. You change the behaviour of the firmware by using M563 S1 which effectively add 1 to every tool number. Then you can use T1 and T2 in you gode files but otherwise you need to use T0 and T1.

Tried this and it didn´t work.
And since I thought that I had something wrong in my toolchanging files I deleted these and just using extruder 2 (T1) at the moment, I have no T0 (Extruder 1) command anywhere right now just T1(even changed the last row in config to T1)
And still the same problem. -
OK so it looks like it isn't to do with tool changes. As I understand it from your first post, the tool heats OK, it starts to print and then it freezes and the web display shows the print progress as 100%, as if the print has finished. This only happens with T1 and never with T0, is that correct?

Yes that's correct, never happens with T0, have had many successed prints when only using T0. I'm now trying with exactly the same g code, just changed T0 to T1 and the problem occurred
-
Is it possible there is a T0 command somewhere later in the Gcode?
Also does it freeze at eactly the same point each time?

searched the whole code no T0, freezes at the same point every time, freezes on a normal G1 movement.

It could indicate a short in the extruder 1 or heater 2 wiring. Does heater 2 show a stable temperature?
When the print freezes, do the axes show as no longer homed in DWC? This would indicate that the Duet is resetting. If so, run M122 to see the last reset time and reason.
-
And yet if you run the same G-code with the initial T1 replaced with T0 it works fine?
Can you replicate this working with T0, not working with T1 on a different gcode file?
-
Is there anything other than a reset that could cause the print progress to go to 100%? If not, then I guess it has to be wiring issue on T1 that is triggering the reset, so a short or some such?

Heater 2 is showing a stable temperature.
When freezing the whole webinterface freezes, can´t do anything (and all axis show homed)Just tried an other g code with the same problem, working with T0 but not with T1, this time it freezes by the first layer doing the first G1.
The privious file froze at layer 4 -
(with the board powered down)
try swapping T0 and T1 and see if the fault moves or stays the same.

If there is a short this must be on the board, since I have tried switching the heaters/thermistors on the board.
Both heaters works as T0 but not T1 -
Tried to run one of the g codes that crashed earlier once more, this time manually line by line in the web interface and surprisingly it didn´t crash.
How can it be that everything freezes when I run the code in auto and not when I run it manually row by row? -
The buffer for the gcode may have a glitch,
