First layer gets ignored
-
Hi guys,
I am new in the duet community, just converted my first printer to a duet(ender 3).
Please excuse my broken English...Got the printer to home as intended, so when I "home all" the nozzle is a sheet of paper away from the bed. But if I start a print the nozzle is at 0.2mm but should be at 0mm. I am a bit scared to set a offset to the nozzle because I think it would crash into the bed while homing. I am using an end stop switch at the z-axis. So no probe installed.
What do I have to do to get the nozzle to 0mm at the start of a print?
-
That's working correctly.
-
It the extruder was at z=0 it would most likely drag the nozzle over the print surface.
In addition the first layer height would be 0, which would mean there is nothing to extrude.
-
That means that I have to set my nozzle to bump slightly against the bed?(does not make sense to me)
Because when I home the hight is correct and when I start a print the nozzle is to high -
When you start the print the nozzle height should be at the height of the first layer which is typically about 0.2-0.3mm depending on your slicer settings.
The print should not start with the nozzle touching the bed.
Your probe offset should be set so that when z=0 the nozzle just touches the bed.
