Hi there,

if I insert a multi line code block with my own regular expression (to match my gcode) everything runs well except there is a blank line directly above the inserted code:

`M117 INDICATOR-Layer28

; multi color
;------------------------------
; PAUSE & PRESENT BED
;------------------------------
;`

I don't know what causes this and I don't have a clue how printers deal with blank lines in gcode. Maybe it's not an issue at all or dependent on FW?

Hello,
I can't actually "find" the UI that you show in your README after installation.
Where is it supposed to be found?
I have OctoPi 0.13.0 and OctoPrint 1.3.6

I'm using the filament change plugin not to change filament but to pause the print so I can insert a nut into the print.
I just use the z up button to move the print head out of the way and after move it back down the same amount of button clicks. I've tried with and without filament retraction and the print still easily snaps apart at that layer.
It's got me baffled. I'm wondering if the z buttons are slightly inaccurate? Do I need to hand write a retraction distance and then return?

Hey, so I downloaded MultiColors and I was using it perfectly for about a week. I just used M300 at certain layers to have the printer emit a tone so I know when its time to change my color. But yesterday I got a new pi3 and reinstalled octopi. I did everything the same. I am on Version: 1.3.0rc1 (rc/devel branch). I have the plugin installed. Now when I run the process it says the gcode was injected. But I get no tones during my print as if the mulitcolor didnt inject the code. What can I do to fix this?

P.S. I already tried updated back to stable and then updated back to devel branch and reinstalled the plugin. Thanks

Injected gcode doesn't seem to apply newlines. Using regex "LAYER:{layer}" and layer 36 with the injected code:

G28 Y0 X0 ; home the X and Y axis
G1 Y120; move plate forward
M300 ; ring the buzzer 
M25 ; pause the print so you can change the filament 
G92 E0 ; reset the extruder origin 
G28 Y0 X ; home the X and Y axis 
; end multi-color

results in

;LAYER:36
; multi colorG28 Y0 X0 ; home the X and Y axis G1 Y120; move plate forward M300 ; ring the buzzer M25 ; pause the print so you can change the filament G92 E0 ; reset the extruder origin G28 Y0 X ; home the X and Y axis ; end multi-color 

Adding /n to the code to be injected didn't seem to work, but /r did, so the new code:

\r
G28 Y0 X0 ; home the X and Y axis \r
G1 Y120; move plate forward \r
M300 ; ring the buzzer \r
M25 ; pause the print so you can change the filament \r
G92 E0 ; reset the extruder origin \r
G28 Y0 X ; home the X and Y axis \r
; end multi-color \r

Results in:

;LAYER:36
; multi color
G28 Y0 X0 ; home the X and Y axis 
G1 Y120; move plate forward 
M300 ; ring the buzzer 
M25 ; pause the print so you can change the filament 
G92 E0 ; reset the extruder origin 
G28 Y0 X ; home the X and Y axis 
; end multi-color 

Thanks.

Not sure what i'm doing wrong

Layers: "254" (Also tried "254,")

Duplicate File: Enabled

All options under "Advanced" have been left as default as i have no idea what im doing.

whenever i click "Process" it give me the error: "Injecting GCODE failed. Replaced 0 out of 1 needed."

I also tried adding 2 layers seperated by a comma or a space n still wouldn't work.

Slicer used to generate the original gCode file is Cura (Not at the computer right now but it's whatever version the latest is as i always keep it up to date and the gCode file was generated about an hour ago when i first started trying to get this plugin working to try).

Printer is Anet A6 baught mid last year. The firmware is the original default firmware it came with (I think it's marlin but i don't actually know as i've never checked). All settings on the printer itself have been left at factory defaults.

Thanks in advance for any help provided

The octoprint python 3 compatibility test says this plugin is not compliant. Any chance this can be fixed?

I'm using Slicer v1.2.8 to generate my GCODE in OctoPrint, and MultiColors v1.0.6 for adding pauses to swap filaments. When I use the built-in GCODE Viewer in OctoPrint to view each layer and figure out where to add pauses, the GUI reports N layers and shows them each as layers 1 through N. However, the GCODE starts with a layer index of 0, so it goes 0 through N-1.

This causes each injected layer to occur 1 layer too late. I realize the fix could be accomplished in OctoPrint (the GUI), Slicer (the GCODE), or MultiColors (modified GCODE). I'm not sure which makes the most sense to report this to, but thought I'd start here. Thanks!!

I use Slic3r and layer comments are on the line for moving to next layer's first position. To do layer change, need to be able to inject gcode before this line.

Example

G1 E574.34601 F1800.00000 ; retract
G92 E0 ; reset extrusion distance
G1 Z1.680 F9600.000 ; move to next layer (6)

Current plugin functionality:

G1 E574.34601 F1800.00000 ; retract
G92 E0 ; reset extrusion distance
G1 Z1.680 F9600.000 ; move to next layer (6)
G91            ;Set Relative Mode
G1 E-5.000000 F500   ;Retract 5mm
G1 Z15 F300         ;move Z up 15mm
G90            ;Set Absolute Mode
G1 X20 Y20 F9000      ;Move to hold position
G91            ;Set Relative Mode
G1 E-40 F500      ;Retract 40mm
M0            ;Idle Hold
G90            ;Set Absolute Mode
G1 F5000         ;Set speed limits
G28 X0 Y0         ;Home X Y
M82            ;Set extruder to Absolute Mode
G92 E0         ;Set Extruder to 0

Desired plugin functionality:

;G1 E574.34601 F1800.00000 ; retract
;G92 E0 ; reset extrusion distance
;Pause Code
G91            ;Set Relative Mode
G1 E-5.000000 F500   ;Retract 5mm
G1 Z15 F300         ;move Z up 15mm
G90            ;Set Absolute Mode
G1 X20 Y20 F9000      ;Move to hold position
G91            ;Set Relative Mode
G1 E-40 F500      ;Retract 40mm
M0            ;Idle Hold
G90            ;Set Absolute Mode
G1 F5000         ;Set speed limits
G28 X0 Y0         ;Home X Y
M82            ;Set extruder to Absolute Mode
G1 E574.34601 F1800.00000 ; retract
G92 E0         ;Set Extruder to 0
; unpaused
G1 Z1.680 F9600.000 ; move to next layer (6)

Note the retract and extrusion reset are commented out (could be deleted) and the retract is moved to just before last extrusion command.

I set up the multi color plugin and tested it with a small 20mm XYZ cube. It seemed to work well after I updated the Regex to look for Cura 4.4's layer comments.

I then used it for a larger model and ran into the issue that it kept pausing unexpectedly ~10 times extra. I realized that having targeted line 13 it was pausing at 13 then 130, 131, 132 through to 139 as well.

I opened the GCode file and searched for '; multi color' and found there were in fact 11 instances of it at the aforementioned layers.

I popped into regex101.com to test some things and sure enough it found every instance of ";LAYER:13" even those followed by another digit.

The only thing I've found to alleviate this is to add a "\n" at the end Regex so it doesn't find other instances.

Screenshots:

I am having the issue of it failing to inject. I am using S3D and the expression used in my gcode is "; layer 13, Z = 2.660" and in the plugin I am putting "; layer {layer}" I have tried most fixes i've found and no dice... any ideas?

Can it be included in a future version the ability to change multiple times in a single print but being able to Choose the extruder to use?

Hi again,

AFAIK some background analysis process is started as soon as you drag'n'drop (upload) a file to the Octoprint webpages. This results in some info, which can be accessed by a small dropdown menu in the file manager and is e.g. used for the Filament Manager plugin.

It seems, a file duplicated by Multi Colors does not trigger this analysis. Do you know how this can be achieved w/o downloading/uploading the GCode?

Thanks!

I'm having an issue with the plugin, when trying to insert some layers.
I'm getting this error in the logs:

Failed to insert code for layer

Here is the entire portion, from the logs, regarding multicolors (the [=] are extra lines for debugging)

After investigating for a bit, looks like the problem is the regex not being found in the file, which is line 80 in init.py, respectively:

test = re.search(search, m)

I'm using the latest version of octoprint: Version 1.3.1 (master branch)
multicolor plugin was installed through plugin manager of octoprint.

PS: File was uploaded locally, not SD, through octoprint. File is located here: /home/pi/.octoprint/uploads/file.gcode

The GCODE file was generated with slic3r.

Thanks in advance !

Hello,
how I check if the injected change filament at layer xx is correctly present?
If I download the file and open it with text read, I can see it?
I have try but doesn't works. I need to check if the pause is present because the file are worked from many peaple.
Thanks a lot.

Hey,
I am trying to understand how to use this plugin.

Would something like this work?
Should I change it in any way?

M83 ; turn on relative movement for extruder  
G1 E-5.000000 F6000 ; retract filament 5mm  
G1 X0.000000 Y0.000000 Z4.000000 F9000 ; home X and Y axis leave Z at current height  
M84 E ; release extruder stepper motor from 'holding' position  
@pause ; pause print!
G1 X0.000000 Y0.000000 F9000 ; upon resume, rehome X/Y in case position was bumped out  
G1 X69.080000 Y58.560000 F9000 ; move back to next layer starting position  
G1 E0 F6000 ; reset extruder, ready to push out plastic again  
G1 F9000  
M82 ; set extruder movement back to absolute ready for next layer

im using anet a8 stock firmware, blender then cura then octoprint with multicolors

gcode sample:

;LAYER:11
; multi color

M117 Change filament
M0
G0 X39.864 Y50.321 Z1.4

tried layer {layer},.*?
;LAYER: {layer}

and a few other variants with no success

thanks in advance

I've output a gcode with Slic3r and noticed a difference in my gcode compared to the other examples I've seen.

My gcode output for between layers is as follows:

;BEFORE_LAYER_CHANGE
G92 E0.0
;1.2
G1 F8640
G1 X231.375 Y111.005 E-0.03360
G1 X231.375 Y109.366 E-0.37842
G1 X231.596 Y109.145 E-0.07214
G1 X231.667 Y107.953 E-0.27584
G1 E-0.04000 F2100.00000
G1 Z1.600 F10800.000
;AFTER_LAYER_CHANGE
;1.2

This refers to the layer height, rather than layer number which is what is being searched for in the regular expression.

I've tried the following:

I get an error because I'm searching for a non-integer (e.g. 0.4 2.2).

Hello,
I have installed the plugin.
I see the tab multicolor but if I click on it the windows doesn't show.
Do you can help me?
I use octoprint version 1.2.13.

Just tried updating to v1.0.12 but after it says it successfully updated and reboots the server it says the v1.0.12 update is avilable in the toast bubble in the top right again.

I have checked the plugin manager and confirmed that the version running is v1.0.11

Here is the output from the update window:

Let me know where to find other logs that may help with fixing the issue. thanks :)

Just as the title says, allow renaming of the changed files so they aren't lost in the file menu with the same name. Also allow duplicate files to be created instead of changing the original file.

Hello. I am running OctoPrint 1.3.2 and installed multi color through gui plugin manager. When I try to use it I get inject failure. Below is info from octoprint log file. Also note I uninstalled the plugin and tried installing it manually which failed.

I have tried Cura, MatterControl and S3D and have yet to get this plugin to inject the necessary gcode though the plugin says it did.... I download it from Octoprint and view in Notepad ++ and cannot find any injected code.

I'm just getting started with using commands and gcode altering so this is still new to me but I want to start getting into color changing. I was wondering if I could get an example of what I would input into advanced options Find Line (regular expression) if I were using simplify3d and trying to pause at layer 14. Is this it:
; layer {layer},.*

Then I'm assuming I need to input m commands in the inject gcode. Are the base ones that are shown (M117 Change filament
M0) enough to get a basic color change?

I'm reading up on the commands now and see that m0 stops the printer and m117 displays the message. I'm guessing I would probably want to input commands that would move the hotend away from the print.

I'm using a anycubic Chiron. (Can't recall the exact Marlin its running at the moment until I get to it at home, buts its whatever comes stock). Thanks for any help!

Hi
I use s3d and the gcode example is

;G1 Z0.3 ; Raise and begin printing
G92 E0
G1 E-1.0000 F2400
G1 Z0.184 F900
; process Process1
; layer 1, Z = 0.184
T0
; tool H0.200 W0.450
; skirt

The regular expression is
;layer {layer},.*

but dont work!

what should I put in the middle of ; layer and {layer},. *

Thanks!

Hi!
I wonder if KiSSlicer is supported by MultiColors plugin. Looks like KiSSlicer doesn't number the layers.
Below is the example of Gcode KiSSlicer produces at layer change. I need to insert @Pause before the start of the layer z=2.2 Which regular expression should I insert into the "look for" field? I wasn't able to enter layer heights because the layer number in "look for" field is an integer. Any ideas/ help/ plans?
Thank you!

===============================================
; END_LAYER_OBJECT z=2.000
; Reset extruder pos
G92 E0
; BEGIN_LAYER_OBJECT z=2.200 z_thickness=0.200
; *** Estimate 4.318418 [s], Slowing (0.603x) to 7.0 [s] ***
; Perimeter Length = 84.589874
; Fan set to Cool value 100%
;
; 'Perimeter Path', 1.0 [feed mm/s], 24.1 [head mm/s]
G1 X109.972 Y75.028 Z2.2 E0 F4200

G1 X110.015 Y75.073 E0.04379 F320.1

This isn't an issue with the plugin at all it works great and I love it!
I am trying to create a script to change filament without zeroing axis and ran in to an issue. I can get the extruder position with M114 but dont know how to cast that in to a variable to use. In the below example I have to manually input the E value from the last line in layer 1, which makes multiple colors a pain. Here is an example with how I do it now and with where I think I need help. Pay no attention to actual values as I need to tweak extrude lengths for a color change, retracts etc.

G1 X104.201 Y138.980 E374.79387
;LAYER:2

; multi color
<-----------------This is where I would load a variable with M114's E value
G91 ;Set to absolute positioning
G1 Z20 F200 E-3 ;retract 3mm of feed stock move 20
G90 ;Set to relative positioning
G1 Y-200 ;Move bed back
M117 Change Filament... ;Display message
G91 ;Set to absolute positioning
G1 F200 E-80 ;retract 80mm of feed stock
M0 ;Wait for buton press( is a resume in octoprint)
M117 Extruding... ;Display message
G1 F200 E100 ;extrude 100mm of feed stock
M117 Press to return to print.. ;Display message
M0 ;Wait for buton press( is a resume in octoprint)
G4 P3000 ;Wait 3 secounds
G1 F200 E3 ;extrude 3mm of feed stock
G92 E374.79387 ;Set E back to last reading <-----This is where I would need to use M114 variable
G4 P300 ;Wait 1/3 secound
G90 ;Set back to relative positioning

Can you run C alongside or is there a way in M/G code to save that data and point to it? Any help is appreciated from anyone, and THANKS for the great plugin!

My bad!

I'm using the dev branch of Octoprint which supports organizing files in folders. The MultiColor plugin only works on files in the root of the storage. It fails when using a file in any folder below that.

I'm getting this error when injecting gcode.

Using OctoPrint 1.3.8 running on OctoPi 0.15.0PE

Thanks for your answer

Hello,

i use cura in repetier-host for slicing.

layer in gcode are :

;LAYER:10

so i try to user this regexp :
.LAYER:{layer}.

but no luck :/

can you help me ?

I have the plugin with default config settings, after updating to 1.3.6 I have been getting the error "Injecting GCODE failed. Replaced 0 out of 2 needed." after attempting to inject into a file. I tried editing the original along with trying to duplicate the file.

Hi there,

it's me again. It seems files in subfolders aren't processed ("duplicate file" enabled)? I tried with 2 different files, it works in the root directory but in subfolders I don't even get a status message "... replaced".

Could you please check? Thanks very much!

Running version 1.0.13

What Slicer did you develop this around?

Sorry, not familiar enough with github to be sure I'm posting this in the correct place, but:

You already optionally allow the adding of "_multi" to the filename. Please allow a further option to add the layer number(s) of the change(s) as well, something along the lines of:

filename_multi(212).gcode
or
filename_multi(212,274,390,416).gcode

This would enable the user to quickly scan the filename to see how soon an upcoming filament change is coming (especially if it's been a while since the file was last printed and you're an old fart who's afraid his memory might soon be faiing) and be prepared, instead of wandering off for a cup of coffee and a bagel :)

Hey,
first of all thanks for the great plugin!
Today I found out that if I inject a pause code at layer number 1 it will also inject it at every layer number starting with a 1, eg. 11, 12, 13, etc. stopping at layer number 20.

I guess the code is just looking at the first digit and stops reading thereafter...

Hello, I downloaded your Multicolor plugin today. I'm a complete beginner so I can't really work with him yet. I want to ask if this plugin works for slicer cura and what are the plugin settings for this slicer. I would like the plugin to pause printing at the specified height [Iayers] and go 10mm head up, then I can eject the filament, give a new one, clean the nozzle and continue ... Thank you for your reply
