Thank you for that Roxy. I'm going to look at the setup on UBL. I'm using bi-linear at the moment. I'm being told that my as my printer (Tronxy 802MA) shipped the Z offset was set to -0.5 in the firmware and I have always ran with 0 offset in the LCD panel. I've now backed up a bit and set both back to 0. This has gotten me close but business card doesn't work anymore. I'm just making small micro adjustments to the sensor to get as close to the print bed as I can but that last adjustment seems to put me "over the top" and I crash the nozzle. I set firmware to -0.5 as was the old firmware. If I set up with the business card method and using the same drag as before I'm too high. Until I feel comfortable with setting up the UBL is there a Z offset that you would recommend in the firmware while maintaining 0 in the control panel?
Caveats...
Printing on 1.9mm glass (never been an issue for me)
Using 1.1.8 now
Thank you
****UPDATE****
So as I said at the beginning of this thread "I am new to the Marlin firmware". Everything that I have learned about the firmware has happened over the last four days. It has taken until now to even understand the hierarchy of the firmware offset vs. offset that I have entered into the panel. So I'm not saying it is right but this is what has gotten printing again. I set the firmware offset to 0 for now because now I understand that the entry into LCD apparently supersedes the firmware. I entered -0.35 into the panel (the thickness of a business card BTW). I just got a perfect print.
So now the question(s) are these. What are the repercussions of this setup? What is the significance of setting the Z offset in the firmware if the panel takes precedence. Any feedback is welcome. At present and being "a noob" (don't let Joe fool you) setting up UBL seems daunting to me....
