1. Could not compile & upload the RepRapGuru Marlin v3 software - it complains about a missing u8glib.h library. Thus we are using the RepRapGuru Marlin v2 software. Could using the V2 instead of V3 software be the cause of the problems?

2. Stepper driver PCBs did not fit perfectly into their slots - they were about 0.5mm too long. After sanding them down, they now fit.
thermocouples and thermistors are quite different things. That resistance is really high for a Thermistor, most are 100K at about 25c.Quote
3. Heated bed thermocouple reports the ambient temperature to be 0 Celcius. Resistance across the disconnected thermistor is ~500 kOhms.
Bed will not heat if it cant read a temperature, safety feature. I would think both should be the same...Quote
4. Hot bed does not heat. Extruder nozzle heats fine. Resistance across the disconnected extruder thermistor is ~100 kOhms. Are the extruder and hot bed thermistors the same?

Post a link to this firmware you are using as this V2 and V3 doesn't correspond to anything standard

Post a link to what your brought also... so we know what you taking about.

Basically the firmware has to know about your hardware, if you just try any random old firmware, its like putting a dolphins brain into a dog, it might fit, but it never going to work
1) identify your motherboard, ramps and Melzi are the most common.
2) examine the configuration.h file... you have to edit that to match your hardware.
I'm somewhat surprised that it didn't already come with firmware....
