Marlin 1.1.0 - RC3 on Prusa i3

The other day I was trying to set up the Discount RepRap Full Graphic LCD on my Folgertech Prusa i3, and I came across that the version of Marlin I was running did not natively support the large display. I decided rather than tweak the firmware a bit, I would just go ahead and install the latest version of Marlin 1.1.0 RC3. I was able to get the display working, although I was missing a bunch of menu items I've seen some other people have (maybe I didn't uncomment a few things in the firmware), but my biggest issue was that when I tried to home all the axis, the steppers went a little crazy. I have gone back to the original firmware for now, but plan to investigate what happened shortly. I was wondering though, has anybody with the Prusa i3 from Folgertech, running Marlin_RAMPS_EPCOS_i38 tried upgrading their firmware to the newest RC, and if they experienced any difficulties? Thanks in advance.

I can't even get marlin 1.1.0 to compile!

Where is it failing to compile? What version of Arduino are you using? Are you using older Configuration.h and Configuration_adv.h files, or did you start with the latest and edit them?

I've tried arduino 1.05 1.50 and 1.67. I've fully setup the config files in the new version, I'm not using any older files. The errors are multiple but always along the lines of a particular line has no operand. Sorry I don't have the full error output I'm not at home. Will post it later.

This is the verbose output from Arduino 1.6.0

This is the verbose output from Arduino 1.6.0...

The issue appears to be that we can't use the min() macro inside of a precompiler #if statement. However, I'm using Arduino 1.6.6, and it compiles it without any problem!
Plus, the error you're getting is "operator '-' has no right operand" which indicates the arguments being passed to min() are the real culprit.
So, what values have you set for Y_MAX_POS and Y_PROBE_OFFSET_FROM_EXTRUDER?

If you can't find those settings, I recommend starting with clean Configuration.h and Configuration_adv.h files, then just bring in all modifications from your existing config files.

Thanks for the help. I did use clean config files for this and changed all the values to the ones I'm using on Marlin 1.0.2. I have tried arudino 1.6.6 also, but I will have a look at the y_max and y_probe values and see if it makes a difference changing them.

Cool. I suspect that the value of Y_PROBE_OFFSET_FROM_EXTRUDER might be an empty string or a floating-point value instead of an integer. It must be an integer.

Compiled thanks for the help, my y-probe-offset read -2- not -20.
