Connection failure

Today I have been working through the online instructions of how to connecting the printer.
I have got as far as all the motors working correctly and knto the heated extruder.

At this point I can moce all the motors and read all the temperatures.

When I click on ‘heat extruder’ the program appears to freeze and I can no longer control the motors.

I tried restarting my computer and recomnecting to the printer, it now shows the temperature of the extruder decreasing down to room temperature over time. But again when I click heat extruder it freezes the program.

Any ideas?

What computer (set-up) are you using?
