Welcome to the SeeMeCNC Community

So I'm using the Repetier Firmware on my RAMBo board (rostock max), and it's been going really well.
I've never bothered with the Delta Calibration or Level delta sections in the Configuration menu, though, and I feel like this could help me fix a problem I'm having with larger prints (i.e., the hot end is higher up while in the center of the build plate and lower around the edges). From what I gather, the LCD menus make calibration pretty straightforward. Unfortunately, I haven't managed to find a tutorial or walkthrough explaining how to actually use them anywhere. I don't want to click around and guess at it; bad things can come of that.

Can anyone help clarify what the menu options do, and how I should use them?

Thanks,

The only fix for this is to change the DELTA_RADIUS in the firmware and re upload it.

I have no idea what the LCD menu setting does, I keep meaning to look at the code, but as far as I am aware there is no description of it anywhere, the Repetier author has minimal knowledge of the Delta code because it was all added by a 3rd party.

Fair enough. I think I found the commit on Github, and I've added a comment for the contributor. In the meantime, do you have any tips on determining how much to adjust the DELTA_RADIUS, or is it mostly trial and error?

Never mind. I seem to have solved the problem. It was my own fault for mis-measuring PRINTER_RADIUS a while back. Now everything seems to be in order.
