New beta firmware 1.20beta11
-
I noticed on beta10 (although I thought I was crazy) and now on beta11 that the layer count is wrong. It is off by 2. For a print 50 layers high, it will finish on layer 52. Right now I am printing the first layer of a print and duet web control says it is on layer 3.
I'm pretty sure it wasn't like this before the last beta or two.

Thanks for the report, I'll check it out.

I figured out why it's doing it. I had a fair bit of baby stepping dialed in and it must be taking that into account when it determines what layer it's on. I reconfigured my probe height and turned off the baby stepping and it's back to normal.
I had made other changes to the printer the same time I upgraded the firmware and was too lazy to go in and update the probe height in config.g.

Thanks for the update. It sounds like I should subtract the babystepping in the layer height computation.

I could be wrong (I usually am) but I have a sneaky feeling that DWC updates the number of layers completed every time it sees a Z move. So it counts a babystep as a layer completed. At least that is the behaviour that I thought I had observed but it was a long time, and probably a few versions of DWC ago.

I noticed that babystepping is also added to auto bed compensation values. It drowe me nuts, I thought that something is wrong with my frame :))

Regarding bad layer count in interface, my current print has 191 layeys, and the interface shows me that the total number of layers is 969…. It may be that is also counting Z lifts during retracts as layers?
-
It works out the number of layers from the object height and the layer height. Is the object height also shown incorrectly?
-
Yes. Current object 22mm height, reported as 310mm. Layer height is correct though, 0.34mm.
Got it!
My ending code does a G0 Z310 to lower the table (cube design printer). This is where the 310 value comes…
I have no idea how to work around this. Any suggestion (good as always)? -
At the end of the G0 Z310 line, add a comment beginning with ";E" or "; E".

That did the trick. Thank you!
