Electronic's, Soldering, and Plugging in Wires

After Thursday of last week we have most of the parts constructed and now we are just trying to test each part using a multimeter. We are running into some trouble as we are not getting acceptable values for the thermistor or the heating resistors. At this point we are having to test the wires again because on Thursday we could not get the right values. We believe it may be caused by our multimeter which isn't the most high tech. After a little disassembly we tested each resistor individually and found each to be about 5 ohm's and with a 1% tolerance we found them to be 3 ohm's in parallel so about 2.5 with the 1% tolerance. After some deliberation we figured to move forward with our work and are now going to try and put everything together so that we can try to calibrate and begin printing on Thursday.
