Welcome to the SeeMeCNC Community

I started the onboard calibration process on my upgraded Rostock V2. The extruder head lowered to the center, moved to the X strut and stopped. Could not get anything to happen after that. I am open for suggestions as to what happened and what do i need to do.
Thanks

Check that the wiring harness is still securely seated in the connector on the hotend,,,,, assuming you "upgraded" to the 280 hotend.

Can you manually move to that position? And take a peek at the output from the console, did it report anything going on?

The screen locks up with

text. I could unplug the printer for about 10 seconds a couple times and the screen showing bed and extruder temperatures would appear. I could then home the printer head fine. I would put in an SD card and try to run the full calibration and it would move to the base and then to the X strut and lock up with the SeeMeCNC screen. Now, I can not even get the temperature screen to appear even after unplugging the printer.

It sounds like an intermittent connection in the hotend whip or connector is causing the printer to reset. Are the wires tight, and when you did the upgrade, did you replace the wires going to hotend? Alternatively, if it's just that it locks up when probing, and not manually, perhaps the code to actually probe isn't active in the V2 configuration, and you didn't get it manually activated cleanly (Repetier is annoying to configure, and it's pretty understandable if it got messed up, as you have a pile of config switches all over the place in it)

OK. I made sure that the whip is completely seated and that seems to fix part of the issue. However, I now can not get the Z axis setting to reset. If I move the extruder to the top near the stops and hit Home Extruder it moves down about 55 mm and stops and has a reading of -55. I can adjust the head using the control panel knob but it stops at -100 mm. If I try to get the head to go up using the knob it stops at -52 mm.

If I move the extruder to the glass plate and try to reset the Z axis setting nothing happens to the setting value.

Is this a configuration code problem?

That sounds like a bad z-height setting. You should try to use something like Mattercontrol to edit the EEPROM parameter for Z-height.

I tried using Mattercontrol However, while it says that the printer is connected and I have the correct initial screen, I can not get anything to work through Mattercontrol (e.g., homing, x,y,z motors, etc.). I believe I double checked all the connections settings.

EEPROM isn't largely about connections. It's storing configuration information (In your case, Z height, is what we care about), which while it includes the connection settings, is mostly printer calibration data. Try options, EEPROM settings. You may want to use Show Terminal first, so that you can get a copy/pastable dump for us here on the forums.

This is what I have when I go into MatterControl Options, Eprom Configure. See attached image

Now trying to run eeprom_write in Arduino to see if we could write to the eeprom, but the connection failed.
It seems we might have to completely rewrite the Firmware into the Rambo but every time we try to send anything through Arduino to the Rambo we receive as follows.

What version of the Arduino IDE are you using? I think that 1.6 is recommended.
