Update

It looks as though I made some mistakes and the Overrides were messing me up. I removed them and now I am much closer to the bad, but I am about -0.29 away from where I need to be. where is the right place to enter in that The nozzle needs to be -0.29 closer to the bed after a G28?

Thank you for your reply,

I think that the problem may have been in the config override, I cleared all the G10 from it and now I can print a first layer.

Old override, not sure how it got this way, probably some meddling on my part

@peter247 thank you for your reply. Unfortunately I have tried this and the result seems to always bee the same, the nozzle prints too a far above the bed. I settled on setting it the way it is now using the guide I linked to.

Good afternoon,

I am using an Ender 3 chassis which has a BTT e3 RRF installed

• I have a BL touch installed and its offset is X-32.3 and Y-32.3
• I have endstop switches on X and Y and use the BL touch to Home Z
• I have a BTT TFT35 e3 installed, I am controlling from DWC

Problem

• When I start a print and G28 Runs, everything homes correctly
• when the print starts, the nozzle is far away from the bed, I can jog it down using baby steps on either the TFT or DWC, but when trying to save the Z-offset (nozzle to bed), the value is not saved and needs to be adjusted for every print

I would be shocked if all you rep rap firmware users were having to baby step on every print, that's not the case right? Even on marlin I could set the nozzle offset and get a perfect first layer every time

• How can I correctly find the nozzle to bed offset and save it so it persists between power cycles?config.g.txt
• If you are going to suggest this guide: Calibrate the Z probe trigger height(https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height), I appreciate your thoughts, but I have already followed this guide and here I am.

I have attached my Config.g and override, please let me know if you need anything else and thank you
