Try to get the bl-touch trigger hight right. I let the nozzle touch the bed(with a piece of paper) and then measured the distance from the bed(without paper) to the lowest part of the bl-touch body. I've read somewhere that this should be 8mm. Then lift the nozzle and perform a g30 s-1. My trigger hight was 0.603. And this was almost perfect for the first layer. This is my setting: g31 p500 x-47 y0 z0.603. I hope this helps.

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 -
First layer gets ignoredposted in Tuning and tweaking
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?
