Hi I recently purchased a used sidekick 289. It had some issues with the BLtouch. I replaced that and now I can print. I’ve been having some issues with the first layer. I’ve tried adjusting the z offset as it’s printing. It seems to me that it does ok in some spots but not others. Any advice on what to do? ![IMG_0092](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/5/575bf0af4b3a07470297d3c439242d7dfc87620f.jpeg) ---

The lines have vertical ridges, so your nozzle is a little close to the surface. Z offset needs to be increased a bit, like 0.10mm, but that’s a rough guess from one picture. ---

I was thinking that as well. As far as I can tell though on the lcd screen it only lets you change by .25mm. I wanted to split the difference because one was to close and one was to far. I downloaded prontoface but couldn’t find the correct code. These dice are also elephant footing and not sure if that’s part of this issue or a separate issue. ![IMG_0074](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/3/322dd62e3cd5f10c56932ef2b0fe1b8942420058.jpeg) ---

LCD screen should be changing by 0.025mm increments. ---

Yes sorry you are correct. I did some smaller first layers test and I don’t remember currently without looking but if set it the one increment of .025 it seemed to high and the other to low. I will share the measurements and results when I can .
