I'm a maker/engineer. I been tuning, adjusting, fixing 3D printers since Nov 2013. I'm committed to using the best materials and getting the best print result for the design taken on.

Hi,
Photo of my printer's workspace.
No problem changing the nozzles upon both of my printers, as I built the one in the corner from a kit.
Mostly only print in PLA, flashfordge can print with ABS, so when printing ABS I don't stand over the machine, can be sat next to it.
Don't print ABS much due to the VOC's released. Desk is within a larger room, shared with others, when I have been printing with ABS, they don't comment about it. Also take a look at a company called 3D Print Clean who have produced a filtered enclosure https://www.3dprintclean.com/

HI,
Looking at the machines settings box you posted.
You need to change Number of Extruder's from 1 to 2
That will give the software the extra settings you need for a duel extruder set-up
I have cura 15.04.4 and in that I have machine settings which has an option for extruder count and drop down for more than one.
Not used cura much but do have a flashfordge Creator Pro with 2 extruders and use simplify 3D to get the required gcode for the printer

Having the print bed still heating after finished printing might be the cause of the slump, as you have mentioned that.
What's the material, temperature settings (hot end, print bed)? Any Photos? Length of print?
Is always best to turn off all heaters when the print finishes. There should be a setting in the slicer which turns off the heaters so that things cool down when complete.

Cool, a nice cheap and easy fix; One must provide a path for the electrons to flow.
Enjoy using the printer

The multimeter doesn't need to be a top end one just basic/mid range one will do, also one with continuity setting will be helpful to find a break in wires, here is wiki page https://en.wikipedia.org/wiki/Continuity_test

If there is an Ohm's reading from the heater cartridge then it's fine and you will need to dive a little deeper as it part of a simple electronic circuit.

The hot end circuit requires power (volts), a Mosfet (aka relay), a PWM signal from micro-controller from a pin defined in the firmware file, heater cartridge and the thermistor (sense temperature). Also take a look at the build instructions for the printer the prusa i3 is quite well documented and supported upon the web. You could just buy another heater cartridge as it's unlikely to have 2 faulty ones.

As you have stated that your printer's controller shows room temperature then I believe the thermistor it's working. If you disconnect one of the wires from the board or sensor. It should flag a heater fault. This a firmware safety feature which breaks the hot end circuit so the heater doesn't overheat the nozzle and wiring.

Also did you check the firmware settings? By using the Arduino IDE and opening the configuration.h file. The i3 most likely uses marlin (that's the name given to the firmware) It reads the data, settings from the given USB connection and tells the stepper motors to move. This you tuber Thomas Sanladerer gives an overview of firmware basics

He also does other videos which will help you get the best from your printer, once you get know them, they are quite simple but frustrating when they developed a fault.
If the incorrect board is configured in the firmware then that will cause the fault .
There could also be break in the power wires or a bad connection which is breaking the hot end heater circuit thus not heating the hot end
To help more you will need to upload photos and details of printer's controller board so able to correct information.

Let us know how you get on

Hi,
printer problems like this one are also logical like computers;
There is a safety features within the firmware which stop the hot end from heating if a fault is present. Able to use a Multimeter?
if so place it on the volts setting, turn on the hot end set temp to 200 and place probes across the hot end wires, you should get a voltage reading ~12 v hopefully you will get one. Now place it on the ohms scale and with the power off, place the probes on the heater cartridge wires, you should get about 3 ohms. If no value heater cartridge is dead, look at getting a replacement and that's the reason it won't heat up the hot end.
