Use this as an opportunity to stock up on a few different spare parts. I recommend always having those tubes, nozzels, heaters, thermistors, and possibly even one set of spare cooling fans. I did one purchase a little over a year ago, was like $40, has saved me from having downtime on several occasions.

Any advice/help on this issue would be appreciated. I had been in the process lately of attempting to install a new nozzle on my Monoprice Maker Select v2., and ran into a wall when the nozzles I ordered did not fit the hot end. Next, I got the correct ones, installed the .3 instead of the .4 as I had intended, got it going, and got the 'def' temperature error. I looked online and troubleshooted some, in the process of some testing/troubleshooting, this happened. I've ordered what I think to be the correct replacement piece, but I'm not sure. https://www.amazon.com/Signstek-Reprap-Ceramic-Cartridge-Printer/dp/B00Q9Z1JUU/ref=pd_bxgy_328_img_2?_encoding=UTF8&amp;psc=1&amp;refRID=YX7HDJM85KX98CNGTZW4

Any help/advice would be appreciated. I don't know how to install it when it arrives, or even if it's the correct thing I need.

Hey I got you... Trust me I've fucked up more hotends than you'll ever think possible... Thermisistor is the wire on your left and it may be broke but seems to be intact. Now your thermocouple/heater cartridge is not intact(its the cylinder with 2 wires sticking out of it. Still inside ths heater block)

Here are a few things you can do to remedy the situation.

take the block completely apart, it may require heating to break up the pla. You will need to take the nozzle off and the throat out.
once apart continue to heat and remove all excess pla inside the heater block. I use a wire brush since its non abrasive and won't remove any base metal. After all the pla is removed reassemble while its heated. This will prevent further leaks.
now for your themisistor turn your printer on and go to where you can see the temp readings if your hot end is reading between 23 to 26 degrees its still good.(+/- 4 degrees tolerance not sure what the ambient temperature of the room is). If the temp is 0 or 290 its broke and you will need a [replacement] (https://www.amazon.com/dp/B01B41K7OM/ref=cm_sw_r_cp_apap_r4GMAiW5oJato) however, you will need to reuse the same board connector.
if you have access to a soldering iron you can solder the thermocouple back to the wiring it pulled out of. Once its soldered start a preheat cycle. If it heats up your good. If it doesn't here is a replacement.

Here is a link to my hot end troubles it might be useful.

FYI I'm a firm believer in be able to fix everything yourself. I believe that this philosophy is very applicable in 3d printing. Otherwise you'll just be throwing money at problems witjout every getting to the source of the problem. Hope this helps. Let me know if you have more questions.

Oh wow, that looks perfect for my intended use and budget. On another note, I found that 3D printer cartridges are dirt cheap and can have around 60 watt density, so that's another option.

Yup I saw both - the two cartridge sellers are:

and

Can you recommend any seller for a proper 6.25mm and/or heating blocks? These two sellers seem to have improper descriptions, and I haven't found a heating block with proper Maker Select specs. UncleChucks seems a bit overprices when compared to Amazon sellers selling packs of 5 for Chucks price of 1.

Is this what you are looking for?

u/scubascratch · 1 pointr/AskElectronics

Doubtful. You really need a schematic to know what is going on with the heater. It could be related to the low/high heat capability.

I would recommend building this out of individual components like these heater cartridges and adding a fan an temperature sensor, and several relays to control them (along with micro controller) unless you can find a simpler space heater with no actual complex circuitry inside.

That little heater you have looks surprisingly complex, several diodes in a probable bridge rectifier configuration, some kind of transformer, etc. it’s not at all clear why a mini space heater needs a low voltage power supply internally unless it has a digital temperature readout or an electronic temperature control (with an adjusting knob).
