Lose all GCODE temperature information

MacLaddy

Hey folks,

I've been scratching my head for a few days now. I could be doing something wrong, but this seems to be a bug.

Version: 2.2.2
Printer: Geeetech A10M
Self Leveling

Issue. The original GCode that comes with the software looks like this.

; Default start code

G28 ; Home extruder

G1 Z15 F{Z_TRAVEL_SPEED}

M107 ; Turn off fan

G90 ; Absolute positioning

M82 ; Extruder in absolute mode

{IF_BED}M190 S{BED}

; Activate all used extruder

{IF_EXT0}M104 T0 S{TEMP0}

G92 E0 ; Reset extruder position

; Wait for all used extruders to reach temperature

{IF_EXT0}M109 T0 S{TEMP0}

When I test this, it works fine. Everything is exported to the gcode file as it should be. I didn't copy paste it, because I already lost it. However, when I add this line:

; Default start code

G28 ; Home extruder
G29 ; Level Bed <<<<<------------------ This line

G1 Z15 F{Z_TRAVEL_SPEED}

M107 ; Turn off fan

G90 ; Absolute positioning

M82 ; Extruder in absolute mode

{IF_BED}M190 S{BED}

; Activate all used extruder

{IF_EXT0}M104 T0 S{TEMP0}

G92 E0 ; Reset extruder position

; Wait for all used extruders to reach temperature

{IF_EXT0}M109 T0 S{TEMP0}

Then everything goes crazy. My actual exported gcode file now looks like this.

;Generated with Cura_SteamEngine 15.01

; Default start code

G1 Z15 F100

M107 ; Turn off fan

G1 X137.283 Y139.425 E48.65816

G1 X114.283 Y139.425 E59.58212

There is no command for extruder temperature, and there is no code for what extruder to use (T0 or T1). And there is nothing I can do about it. I can uninstall and reinstall the program, and it will start working again. But as soon as I add that G29 line just a single time, then everything goes crazy on me and will not output temperature or extruder code.

Am I missing something simple?

Thanks,
Mac

I copied your block and it works fine.

In your non working result G29 is also missing, so you either did not safe the new profile or on the right tab you have selected a different profile then the one you edited. Would be the only explaination that makes sense to me knowing that it can work.

I was saving all of this code in a different notepad file. I tried removing the G29 line to see if it would go back to normal and resaved it. That's actually what you're seeing. I copy/pasted the wrong one.

It's a brand new install and only has a single profile, and even after removing the G29 line it doesn't export the hot-end temperature or extruder information.

I've duplicated the results on a second computer. I'll do it all again this evening with a new install and add some comments in the profile code. I'll try to show it more explicitly, but this does appear to be a legitimate bug.

Thank you for the help. Let me know if there is anything else I can try to either confirm the bug, or find what setting is wrong.

Did you select Extruder1 in your profile instead of Extruder0?

That would explain the behaviour as {IF_EXT0}M104 T0 S{TEMP0} generates output only for extruder0.

For extruder1 ist should look like {IF_EXT1}M104 T1 S{TEMP1}

Repetier

Note that work directory gets not updated or deleted on install/uninstall. So fresh means you delete CuraEngine folder in work directory and restart host. In addition to @RAyWB comment which is definitvely true, do you have defined extruders in host for the printer?

Aha! Now I feel really dumb. I probably should have mentioned this is a dual color printer. I have two extruder motors, but only a single nozzle/mixing extruder. I should have recognized what was happening with the g-code "if" statement, but I'm not savvy enough with it (yet). So yes, that was the main issue. I was slicing on the second extruder (T1) but the code only looked for the first (T0).

I changed the start g-code to this. I don't know if this is the best way to do it:

; Default start code

G28 ; Home extruder

G29 ; Level Bed

G1 Z15 F{Z_TRAVEL_SPEED}

M107 ; Turn off fan

G90 ; Absolute positioning

M82 ; Extruder in absolute mode

{IF_BED}M190 S{BED}

; Activate all used extruder

{IF_EXT0}M104 T0 S{TEMP0}

{IF_EXT1}M104 T0 S{TEMP1}

G92 E0 ; Reset extruder position

; Wait for all used extruders to reach temperature

{IF_EXT0}M109 T0 S{TEMP0}

{IF_EXT1}M109 T0 S{TEMP1}

I'm not sure why Repetier doesn't automatically account for this. My printer was set for two extruders and a mixing nozzle. It may be something to account for in a future update.

However, I am still confused by something. Just for the fun of it, I loaded a multi color lizard from Thingiverse. I did a couple things just to see how it works out in the g-code.

First, I set a Skirt to print. In the settings, I say the support extruder is Extruder 2, so the skirt should be printed with T1.

The body of the lizard is also extruder 2. So it should print with T1.

The eyes are a different color and extruder 1. So it should print with T0.

I would attach the g-code for this, but I don't see a way to do it. It starts like this:

; Default start code

G28 ; Home extruder

G29 ; Level Bed

G1 Z15 F100

M107 ; Turn off fan

G90 ; Absolute positioning

M82 ; Extruder in absolute mode

There is nothing in this code that tells it to start at T1. Shouldn't it start there, since the support material is set for the second extruder? It heats T0, which makes sense as it is a mixing extruder. But I don't see anything to indicate which extruder to start with. In fact, when I search for T1, I don't find it until line 1,085, where it now says ;TYPE:SUPPORT. If support is just starting now, what was it printing before? I haven't actually tried this print, so it probably works fine. But I'm curious how this works.

Thanks to you both for all the help.

EDIT: I figured this one out, so you can ignore this post. If you're curious, Repetier Host ignored that filament profile and defaulted to the default. That one had 50°. I don't know if its a naming issue or something with the config file that I downloaded from Geeetech, but it obviously didn't work. I'll just delete that profile and create my own. I'm still curious about my question above though.

SOLVED
I'm using two computers. The one I posted gcode from above looks like it would have worked successfully, at least for the temperatures. This computer runs my printer, and it looks like here this issue goes over to the heated bed as well. I loaded an xyz test cube to see if I could get a successful print going. This is my start g-code:

G28 ; Home extruder

G29 ; Do what I say, when I say it.

G1 Z15 F{Z_TRAVEL_SPEED}

M107 ; Turn off fan

G90 ; Absolute positioning

M82 ; Extruder in absolute mode

{IF_BED}M190 S{BED} ; WHY WONT YOU LISTEN TO ME?

; Activate all used extruder

{IF_EXT0}M104 T0 S{TEMP0}

{IF_EXT1}M104 T0 S{TEMP1}

G92 E0 ; Reset extruder position

; Wait for all used extruders to reach temperature

{IF_EXT0}M109 T0 S{TEMP0}

{IF_EXT1}M109 T0 S{TEMP1}

Take a look at my filament settings. I snapped an image and have the exported g-code on the side. You'll see I'm using the correct profile names.

For some reason, this is exporting with a 50° temp instead of 55°, as in my settings. It looks like that was happening in my first post as well. I just hadn't noticed it.

This is my printer extruder setting. So it isn't a maximum temperature issue.

do you use same filament settings for both extruders ?

i´m not that familiar with cura but might be an issue if second filament has a different bed setting

Sorry for all the posts. We're probably on very different time zones, so I'm moving through things and discovering different issues/solutions. This will be my last one.

Let me first say, I love Repetier Host. This program has always worked great for me. But...it doesn't do well for two extruders and a mixing nozzle. I sliced the test cube on extruder 2 (T1) and printed. It didn't work. It printed with the first extruder. Not surprising, because there is nothing in the g-code that tells my printer to use the second extruder.

There is a workaround, I just had to add T1 into the start g-code, but then I have to remember to use the right profile setting. This seems like another upgrade that Repetier could make. It is just one line based on what extruder you choose for your part.

I edited the post above. I actually found the solution to that one. It was ignoring the profile setting, which I had downloaded from the Geeetech website. It defaulted back to default.

Repetier

Just some comments: CuraEngine with out rype of config is not developed any more and at the time it stopped it was quite picky about 2 extruder support, e.g. you need to use extruder 1 on an object if you want to use extruder 2 as well. Also beside the start/end code all comes from curaengine and I can not change the behaviour. That includes start extruder I guess.

You are not the first mentioning the settings are not being used, but I can never replay the problem. So I still think these users do something wrong and I can not say what. Importent fact is left configs must be saved so the changes are used. Also selecting them on the left side does not use them - you need to select the profile on the right side in the dropdown box. Actually normally left side is never opened once you found your settings.
