Error in Gcode file? Operation failed (Reason:err 1)

[JUNK]

Hi @Phaedrux Thanks for your attention.

I am using DWC 2.0.7.
The forum software will not allow me to upload a .zip file so I have changed the extension to .txt. You will need to change it back.

Colours 14 to 22 - Cylinder - Real Filament CYM 22 Colour Idealised.txt

Otherwise, I have shared the uncompressed file on google drive.
I am happy to put it somewhere else if it is easier.

I think the next thing to try would be to have a fresh install and upgrade to the latest version (3.1.1) and do all the required config.g updates.

Thanks
James

Thanks for the file. I have reproduced the problem and I am investigating it.

This line in the GCode file is triggering the error:

; filament used [mm] = 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1685.8, 1264.3, 1264.2, 1264.1, 1264.0, 1263.9, 1263.8, 893.5, 1029.2

At the same time as renumbering the tools, you should delete the 13 leading zeros from that line to get:

; filament used [mm] = 1685.8, 1264.3, 1264.2, 1264.1, 1264.0, 1263.9, 1263.8, 893.5, 1029.2

@dc42 and @Phaedrux

I have made the modification to the gcode file and I am now printing. Thank you.

Out of interest was it the number of items in the list that was causing the problem or the fact that the entries were zero?

Will this issue still exist when I upgrade to 3.1.1. ?

Thanks again

James

The number of items in the list was too large. It will be fixed in release 3.2, also in 3.1.2 if there is one. However, even with that fix the computed filament requirement would be wrong because of the tool renumbering, and that would caused the percent complete and print end time estimations to go wrong.

@dc42 Ok, does that mean that it would be better to define multiple tools in the config.g but have them refer to the same hardware?

@deckingman

Thanks, I think it was your blog post that I followed when I first set my printer up. Thank you for that.
It looks like I made a mistake when I drifted from your recommendations.
I was trying to simplify my config.g and have all the colour selections dealt with by the slicer. I would still like to do that, but I think that I will override the mixing ratios in the gcode and have all my tools defined in the config.g as generic. I am guessing that the filament estimates are based on the tools rather than the gcode. I will have to investigate and experiment further. (just thinking out loud)

Thanks

[deckingman]

@JUNK It depends what it is that you want to achieve and there are usually several options to achieve the same objective. If the object is made up several distinct shapes which have to be different colours, then I find it easiest to create separate stl files for each piece and assign a specific tool to each of those pieces. But I may change the mixing ratio for those specific tools in the slicer start gcode. If the object just has bands of colour or perhaps "fades" from one colour to another, then I find it easier to use one tool and post process the gcode file to change the mixing ratio every "n" layers. Having said all that, I never take much notice of the filament based estimates. So they might "get confused" if one changes the mixing ration within the gcode file.

One thing to be aware of is that the latest firmware versions now have a limit of 50 tools (number 0 to 49 IIRC) but in earlier firmware, no such limit existed. It shouldn't be a problem but just be aware of the new limitations.

@deckingman Good points. Thank you for the information. I am currently subscribed to the "Diamond Hotend users" and the "3d printing multi material and multi coloured" groups on Facebook. Can you recommend anywhere else to follow?

No sorry. I don't "do" social media.
