layer height doesn't update at each layer change and extruder icon issue #1314
Comments
Hi. The first "issue" is a feature which was implemented to make sure that a preheat is made before extrusion. It caused confusion and will be changed with the next release of the firmware. Regarding Layer hight. Does this happen while printing from on board SD or a storage which is attached to the TFT? When it does not update, do you mean it updates late or does it update to a wrong value or does it skip certain layer hight at all? Please let us know, thank you |
@Chukozor Do you use ARC in your gcode? (G2, G3) |
no, there is only G0 and G1 in the gcode I used |
@oldman4U ok thanks. |
Out of 10 how many times does it skip? And have you seen this before?
Which layer hight are you using? Can you attach a gcode file?

… @oldman4U <https://github.com/oldman4U> ok thanks.
For the layer issue, I printed with SD card on TFT in TFT mode it skips
certain layer height on the screen but not in the print (hopefully).

@oldman4U I don't know, I only updated the firmware yesterday and made one print. |
.85 or .75? |
Forget it. Initial layer hight is .25 and all following are .2. All good. Testing it with a dry print at 999% speed;-) |
Could you please try it again and next time the Layer hight stops - click on More and then Back - to see if the Layer hight updates to the correct value. Thank you |
ok I'll try that, but I won't be able to print for several days. I'll try this for sure next print. Thanks |
If you want, you can close this ticket. I am able to reproduce the issue here, so next I will find out which PR caused this and contact the developer. Thank you |
thanks!!! |
I found the bug. It was introduced by PR #1272. Actual coordinates are obtained by sending M114 to Marlin, which is not done during printing to avoid unnecessary serial traffic while printing. PR #1319 fixes this. Later edit: |
Hi again, @kisslorand I tried what you wrote and I had the issue "nozzle dives in the bed" at each layer on the same point (not even at the layer change). You can see the effect on the photo here.
|
but I didn't try the update #1319 , I just changed the line you told and compiled it. So maybe this update has no more this issue .... ? @kisslorand |
Please try the current master firmware which includes all fixes. Please help the community and close the ticket once you do not need it anymore. Thank you |
@Chukozor The "layer height doesn't update at each layer change and extruder icon issue" should have been resolved already. This new thing you have should be treated in a separate ticket. If you open a new ticket about it, please check before if the behaviour is present on any gcode you try to print and please provide a sample gcode also, a smaller one, if possible. |
And in case it has been working before please provide also the good
firmware

I tried the firmware in the folder "copy to SD", unified menu, TFT35 3.0, used in the commit 198f14e (on a BTT SKR 1.3).
I found two issues :
