New RepRap - Rostock - Not connecting in RepicatorG

Just finished building a Rostock RepRap and loaded firmware based on the following README doc on my
mac OSX


Configuring and compilation:
============================

Install the arduino software IDE/toolset v22
[www.arduino.cc]

Install Ultimaker's RepG 25 build
[software.ultimaker.com]

Copy the Ultimaker Marlin firmware
[github.com]

Start the arduino IDE.
Select Tools -> Board -> Arduino Mega 2560 or your microcontroller
Select the correct serial port in Tools ->Serial Port
Open Marlin.pde

Click the Verify/Compile button

Click the Upload button
If all goes well the firmware is uploading

Start Ultimaker's Custom RepG 25
Make sure Show Experimental Profiles is enabled in Preferences
Select Sprinter as the Driver

Press the Connect button.

I've tried reinstalling several times, reinstalling, powering down, unplugging, etc with no luck, any help?

Extremely new to all reprapping, excuse my ignorance, I have now switched to Pronterface and am able to get connected, but have the following error:

Error:0
: Extruder switched off. MAXTEMP triggered !
Errorrinter stopped due to errors. Fix the error and use M999 to restart!. (Temperature is reset. Set it before restarting)


Planning to check the output of the thermistor pins and that my thermistor is hooked up and functioning correctly

Either

a.) the thermistor for your hotend isn't connected. Verify that you read a resistance at the head end of the leads (the plug you put onto RAMPS), and that the resistance decreases when heat is applied to the thermistor - your thumb will do nicely.

or

b.) you have the wrong thermistor selected in the firmware. Check the 'configuration.h' tab.

But...

Doesn't the rostock need a custom firmware? It's a delta robot - not a cartesian. You should google this...

ooo i love rostocks !

yea i think rostocks use a special marlin or something

I took some time Thursday night to troubleshoot, everything seemed to be connected correctly, but I switched the hotend to a different thermistor connection on the RAMPS board and made the corresponding change in the firmware and was able to get connected with no errors. I then tried to home the rostock with G28 in pronterface and it would just jerkily move a few steps. I got more movement trying to home individual axes, but it's not quite doing what it's supposed to yet, BUT I do have some movement, so I am not hopeless anymore, but would love to hear if anyone else ran into problems getting their rostock to find home. I have updated to the newer modified Marlin firmware (removing the 3 bottom end stops).

I will keep iterating

thanks
