Cura 15.0.1 - Manual select second extruder changed

[macua85 52]

In the previous version of cura, I could edit the gcode and put T1 in place of T0 to use the second extruder for a print. However it seems this is no longer in the gcode:

Which bit do I change now to print from second extruder?

 

Thanks

I might be wrong since I never tested dual extrusion but I believe you can simply add T1 at the top of the gcode to tell it to set that nozzle as active.

Thanks for the link! However, I have no idea how I add plugins to cura

 

[macua85 52]

Its a mac by the way. I can't find any literature on it googleing. Is there a way to manually edit the gcode as in previous versions of cura?

I actually came to post a similar comment/question.

I made a quick little plugin I could activate and it would switch the T0 to T1

so I could print using the secondary extruder. But the removal of it breaks

the plugin. Why wouldn't the slicing engine always output the Tool number?

What is the reasoning behind the change? I also notice that it forces the bed

heatup with set and wait (M190) before setting the temps on the extruders.

I suppose there isn't a nice way to set these behaviors to what I prefer?

I assume that this only happens if more than one extruder is used for a specific print. Seems very logical to me...

But if you wrote your own plugin - adding a preceding T0 (respectivley T1) and modifing the start-gcode for your needs shouldn't be such a big problem...?

This. Some older and strange firmwares don't accept the tool change commands. So for single extrusion it's better not to emit the tool change commands.

I have installed this plug-in and it does select the second extruder, however the nozzle temperature always gets set to zero.

I then have to edit the G-code in notepad to correct the temperature setting.

Any chance of getting this fixed, as the plugin is very usefull.

 

[Dim3nsioneer 558]

Very strange. The plugin might only fail if there is no M109 command (or an M109 without S-option). Could you check your gcode please? Do you have an unorthodox start.gcode?

Please also make sure that if you use another plugin which changes the nozzle temperature, e.g. TweakAtZ, AFTER the SelectExtruder plugin, you have to apply the temperature for the second extruder; if you use the other plugin before the SelectExtruder plugin, you have to apply the temperature for the first extruder.

And the SelectExtruder plugin does not work with dual extrusion prints at all.

Macua85, If you edit the "Start/End-GCode" in Cura, modifying the command M109 and adding a new line M109 T1, like this (where S255 is the temerature setting for the filament. In my case I use 225 ºC) it works perfect.

You have to copy the file selectextruder.py in the folder \Cura_15.01\plugins.

Then activate it the next time you open Cura.

I'd like to use this plugin but have no idea how to copy this .py file. I don't see the file to download.

The link attached above no longer works - but don't worry. There is a really easy fix!

Like most of you, I took a look at my G-Code and saw that there was no T0 or T1 anywhere. I found that really confusing but figured that T0 was the default setting, somewhere, anyway. I tried just popping in T1 in the M109 S215 line but that didn't work - T0 still came out to print...  It seems that after the G92 command (all listed above in previous posts) the Sigma reverts to using T0 anyway.

I've been using a beta version of Cura designed specifically for the BCN Sigma machine and, just in normal Cura, for some reason there is no click box that specifies you just want to use the second extruder. My first extruder is having issues so I wanted to print with the second.

The result was that T1 was hot and extruding in preparation for printing, but then T0 was going out and trying to print cold anyway.

My solution was just to rewrite T1 underneath the M117 Printing message. That fixed it and I'm now printing perfectly happily using the second non-faulty extruder.

I only encountered this problem because of firmware issues at BCN. USB printing is currently out of action and I'm having to use an SD card. Otherwise I'd be using what I usually do - hooking my printer up to an IoT device and slicing using Formide - they have the click box button. Seems like a really obvious thing for Cura to miss out/remove considering I'm using a version tailored to a dual extruder printer.

So, in summary, just write T1 at the end of the Start G-Code if you want to print using the other extruder. Otherwise the printer reverts to the default T0.

Anybody know why this is?

Hi,

I'm using the UMO with all upgrades, inkl. Dualextruder. It's all fine...

BUT : Sometimes I wanna print with another filament, so I decided for ABS using the 1st extruder and for another filament (lower temperature!) the 2nd extruder. I tried to print just with the 2nd extruder only!

So I use the "selectextruder-plugin" (in Cura 15.02.1) from "Dim3nsioneer" and it works... but not really!

If the heating-procedure is done, the temp of the 2nd nozzle gets to zero ...and nothing happens at all...

So I allways have to "tune" the temp manually up, so the prints starts... and (then) it is working fine.

I find several threads about the gcode... and I tried to fix it but there's no hope ...

Please, is there anyone out there, who can post a complete gcode-profile, so that I can print ONLY with the 2nd extruder (if I want to)?

there must be a simple trick... is'nt it!?
