Ok, this next step has me a little nervous. I just finished assembling the extruder and now the directions tell me to hook the rumba board up tot he heater and the thermister in the hot end and bring it up to 220c and then tighten it.

1. So did you guys skip this step and come back to it when you had all your electronics mounted and hooked up? And to I need to have the heat sinks on the stepper drivers before I apply power to the rumba board at this point or just before I actually try to drive motors with it?

2. What did you set the hot end on while it was heating up?

3. Any other advice around this step other than don't get burned? lol
