Needed - a comprehensive and detailed hardware troubleshooting guide
Hi there.
Please help. I have a I3 Mk3 upgraded to a Mk3S that is down hard.
Is there a comprehensive and detailed hardware troubleshooting guide out there anywhere? I need something that goes end to end over the electronics first - printing is not the problem when it works. Over 1 year my Mk3 printer has had a cascading series of failures; 1. the spool holder snapped and dinged my print plate, 2. the PINDA sensor went out, 3. the Print Fan failed, 4. bed Thermistor failed, 5. the Hot end Thermistor failed. I got the kit and did the upgrade but I have yet to get it to run as a Mk3S!
Now the thing is telling me the the bed won't heat up. I've had the printer for over a year and per the display I've got just over 24 hrs print time!
Please - is there a PDF document telling me how to test all of the electronics in a logical procession end to end?
Thank you.

It is in the works but far from complete.

@bobstro
Thank you for your info. links, I will keep them for when I figure out what's keeping my printer down. I did read over your "Troubleshooting hardware problems" and nothing in there would be related. But again - big thanks for reading my post and sending me info!!

Instead of digging through blogs and forums there truly is a need for a TECH MANUAL for this printer, I have wasted tons of hours looking for parts and solutions.
EXAMPLE: PART DATA SECTION might look something like this:

(1) NTC 3950 100K Thermistor
(2) High Stability NTC Thermistor 100K -- Note: NTC stands for Negative Temperature Coefficient
(3) 1.25mmx2.0mm glass bead
(4) accuracy: 1%
(5) Resistance value at 25°C=100K
(6) Wiring insulation: high temperature teflon/PTFE
