Any trouble tips how to wire the end stops? If I hold the switch and press forward on the printrun, is that how to test if it doesn’t advance. should that work?

while in motion, if you manually trip the end stop and the motion stop then everything works fine as expected. if it keeps on moving, then I suggest you quickly pull the plug and inspect the wire connection.
Did it work, @lowdragdesign?
you could do that but that’s a bad way of testing your endstops!
send a M119 command to the printer and it will return the endstop status you can test all the endstops without moving the XY or Z its beter for your belts, rods and fingers 
put your endstops where you want them then configure your home direction in the firmware
for instance my printer homes to X max Y min and Z min the X is the wrong way around but I wanted my wiring to be at the same side as the X stepper motor so I could tidy it up.
I have problem with the thermistor now; printrun says max temp ~454. Not sure what changed. I can’t check the switches before the printer can connect without errors. I’m going to try reflashing the marlin firmware, doesn’t seeem to be changing anything when I’ve tried that before.
That sounds right!, Thank you, I will try once I can connect to the printer again, 
My M commands, I have not tried much of.
I can not connect to the printer right now, the thermistor max temp locked. 
in the marlin firmware under “thermal settings” you set which thermistor your hotend and heated bed are using the most common ones used are the Honywell (option 7) or EPCOS 100K (option 1 or 6)
for a single extruder and heated bed it would look something like this (example using 100k EPCOS thermistor):
#define TEMP_SENSOR_0 6
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 6
you should know what your thermistors are and you can esily check them with a multimeter if you look up the datasheet it will tell you the expected resistance for a given temperature, you can easily use room temperature and the value for that to check the thermistor.
oo I didn’t think of checking with the voltmeter, thank you!
