Empty Layers causing incorrect layer count
-
Please can you provide a GCode file with Z hop disabled that exhibits the problem. It will be easier to debug.

This Gcode was generated with Z-Hop off, but still caused the empty layers issue. -

From a remark you made earlier, I assume that you are using a Prusa version of Slic3d, if so, be very careful \ suspect for the gcode that it gives, as the Prusa versions are almost hard-coded for his printers e.g. board configuration, mesh leveling etc. while giving great results on a Mk2\Mk3 but inconsistent results on other printers.
I have also tried the Prusa version of Slic3r but have settled for the standard version of Slic3r and simplify3d.

This Gcode was generated with Z-Hop off, but still caused the empty layers issue.Thanks. I've tried printing that file. My observations:
-
I removed the heating commands and instead enable cold extrusion. The current layer remained stuck at zero. On investigation, this turned out to be because the print monitor insists that a nozzle has reached operating temperature before it considers that a print has started.
-
If I set the temperature of tool 1 to 100C and then run it, the current layer increments with Z height exactly as I would expect.
When you get the "empty layers" issue, does the current layer remain stuck at 0 while the issue persists? If so then it's probably something to do with the way the print monitor module monitors the heating.

I currently don't have access to my printer, i will check if that is the case tomorrow.
Meanwhile, since this seems to not be a common issue i was thinking about the conditions that might be different in my case specifically to cause this behavior. The empty layers seem to always be listed after the first layer is completed, so could the issue be caused by:
-Having the printing temperature reduced by a few degrees after completing the first layer while also
-Having the standby temperature set to the first layer's printing temperature (I manually set it before printing so that the tool doesn't cool down while homing)I was thinking that might confuse the logic since for most users there would be no reason to have a standby temperature higher than the priting temperature...
Again, i will test for this too when i have access to my printer tomorrow.

Please test with firmware 2.0RC5 tomorrow - I think you may find the issue is fixed in that version.

Excuse me please for taking a bit longer than expected to try this out.
I updated the firmware, but the issue persists. Not changing the printing temperature at all during the print hasn't fixed it either

Try 2.0RC6?

A quick update:
Excuse me for taking so long to test things out, i have a lot of work to do at the moment so i have very little time for 3D-Printing.
My last few prints have been printed with the first extruder only, and so far the issue has not appeared again. I hope that helps a bit in diagnosing the issue, i will also try the new firmware next week when i have a little bit more time.
As a sidenote, thank you very much for the support so far, and for putting up with my slow testing
