"Time to Next Layer" not displaying... #30

Closed puterboy closed 2 years ago

Unless I am missing something, I don't see the "Time to Next Layer" displaying even though it is checked in the settings. I am printing with a Prusa MK3S+

OK. I figured out the problem... Prusa printers use a different comment to signal a layer change --- "^;LAYER_CHANGE"

So use the following settings to get it to work for Prusa printers:

Description: Time to Next Layer Regex: ^;LAYER_CHANGE Format: Next layer in ${formatDuration(this.progress.printTimeLeft - this.plugins.TimeToFilament["^;LAYER_CHANGE"].timeLeft)}

This may be helpful to add to the documentation...

It's not the printer that is using a different format, it's the generator of the stl file. So like, Cura versus Prusa slicer, etc.

If you can send me a sample file and I can adjust the default config to support that other format of layer change.

The gcode is ridiculously simple. As per the regex in my previous post, the layer change line simply looks like: ;LAYER_CHANGE

Part of the reason I suggested a feature request to track the number of matches as of the current position is so that one could add a layer number to the layer detection since Prusa slicer default layer change comment doesn't include the layer number.

Ah, I see! There's no number! Hmm. I'll have to think about how to fix this!

That's why I was thinking it would be helpful to have a general utility that could count instances :)
