Layer count

terabyte

What if I print with several different layer heights?

Merlin

I'm using Matter Control and the latest Web interface is not showing a layer count at all.
I' have tried using the tip above: ; layer_height = [layer_height] but thjis makes no difference:
Here is the first few paragraphs of some gcode produced showing the start and end codes.
Anyone any ideas what I'm missing?

I'm no expert on this but could it be that Matter control uses the "variable" name "layerThickness" rather than "layer_height"?

Good catch. I wish slicers would all use the same names in the comments they generate. I'll have RRF accept layerThickness as an alternative to layer_height in the next release. Meanwhile, try changing it inside the square brackets in the comment.

Hi Merlin,

Can you make a gcode file generated by Matter Control available to me, so that I can test some new layer height detection code?

FYI, seeing layer count issues with S3D as well. Doing a print that has 251 layers and the DWC is showing 750 layers. Oddly I've seen 750 often, I think it's my max layer count for my setup. Yep it is, says my object is 150mm high. It is showing the two layer heights which is also incorrect as the first layer is set to 100% of 0.20mm. Ok, well not the end of the world I guess, it works on some prints.

So was your object actually only 50mm high instead of 150mm, or was the layer height shown by DWC only 1/3 of the real layer height?

InSanity

The object is 0.2mm X 251 layers so yes 50.2 mm high. The printer is showing 150mm and 750 layers. This is a direct slice right from S3D 3.1.1 without any types of edits. Sliced, saved, upload, print. It seams to sometimes work and sometimes not. I see 750 layers often.

Here is the G-Code for your reference: The File

David,
Sorry did not respond to your request of Jan 13th.
Somehow I am not getting advised when threads I have contributed too are updated.
Where do I reset this?
As you have now released 1.17c with the MH layer fix I assume you no longer need any more gcode examples.

dc42

Merlin, please let us know whether 1.17c fixes the problem. I was not able to test the fix.

InSanity

Any ideas on the S3D layer count issue? I did a print last night with the same 750 layers showing when it shouldn't have been.

Thanks,

Jeff

WebControl seems to be displaying inaccurate info while printing.

The progress Bar is stuck saying "Layer 2 of 440" and not incrementing ; Cura say theres only 100 layers

@Shotfire, can you make that file available to me via Dropbox or similar?

burtoogle

Hi shotfire, is your print spiralized? Webcontrol doesn't show the correct info when printing a Cura spiralized model.

Shotfire

@burtoogle, No, I'm just printing a a new box for the DuetWif right now. But it happens on every print I do no matter what size or shape

burtoogle

That's weird, I'm using Cura 2.5 and the layer stats + time prediction all work as they should.

burtoogle

I would also like to take a look at one of your gcode files that are misbehaving. As DC says, can you put it on Dropbox or similar.

Shotfire

I have put it on my dropbox but I don't use dropbox very much, I think I need your email address to give you access

burtoogle

Using the dropbox website you can make the file public and then copy a link which can be pasted into the forum here.

My DWC has been today stuck with 1399 layers. Third print today. Even with different browser sessions. DWC seem to have some problems updating layer counts between different prints if the same session/browser window is used, but now this one happens even with different computers. And I have not had a print with 1399 layers.
