General

I have purchased a 32 gig micro sd card to use for my prints.
Problem: My laptop shows files that I have added to the card, but when I put it in the printer it says: No files found
Any ideas?

I was given a non working Mini. Intention is to use .3 or .25 nozzle for tiny projects. I have an Ender5 already. For the life of me I cant figure out how the fan attaches to the hotend. There is a loose spring? Any diagrams out there? I cant locate it. Also no power supply so what am I searching for on Amazon?.

I was printing something over the night but when I woke up the print had just stopped. Ever since then the printer won't read the sd card, won't move in any axis or extrude, and the temperature just reads 0 for the bed and extruder. Any help would be appreciated.

So my mini will reach 60 if I only preheat the bed and nothing else. If I begin to preheat the Hotend, the temperaure begins to fall. I purchased this printer and the heatbed was bad. I prdered a Heatbed via Amazon and did the wire relocation using the printed part. It was working okay, it seemed to heat up slowly, so I did a PID adjustment using the info from Tyler. Well, now it's worse than before and it seems as if though its progressivly getting worse. At first it was just one or two degrees and this is normal for these printers from what I have read. But it's steadily declining. Now my heat bed is set to 60c and it is floating at 47-48. I have opened the printer a few times and inspected visually the connectors and board, no signs of any damages, cold joints, burnt pins, etc... Any more help or advice would be welcome. I have a second heated silicone mat, and the Ramps board to add a second heater to the build plate just because the printer has always been slow to heat up. Fearful to move forward if there could be something else going on. Notable to mention I have two of these MPSM V2 with the most current Firmware. 1 in black and one in white. All of my problems have been with the white printer. Also notable to mention. The black printer from the factory has had the heat bed wires relocated to a newly added cuout in the body. Again, I have replaced the white printers heat bed and re routed the wires so they have no resistance or strain.

I purchased a Monoprice Select 3D Mini printer about 8 months ago and felt the same way that most of you have when I received it and put it to work. It was easy and inexpensive. I was thrilled . . . until I started having issues with it. At first the print head went out. No big deal, I just picked up one on ebay and snapped in the replacement. The latest issue was when the USB port stopped working. I RMA'd the printer with Monoprice and then got an email saying that, because it had been modified (print head replace?) that they would not warrant it. The print head had been replaced 4 months earlier and could not have possibly caused the USB port to go bad. The tech, Ian, refused to escalate it to his supervisor and refused to put me in touch with anyone who I could talk to.

Monoprice is great, until it breaks. Then Monoprice sucks. Buyer beware!

I have been printing successfully with my V2 for a few years now. About 15 rolls of material Petg and PLA. Always printer great. Upgrades metal extruder and E3d Lite hotend. I have been printing masks for my son and fellow residents and started to experience under extrusion. The tip of the Bowden tube had shrunk inside the hot end. I had an extra E3d V6 with E3d X nozzle so I replaced the entire hot end. I did a 15 step PID autotune, Calibrated the extruder and releveled the bed. I am still getting random under extrusion and clicking of the extruder. I again replaced the extruder with no difference. I increased the extruder and recalibrated with no difference. I slowed the printing to 30% with little difference. I am trying to print respirator parts using the same g-code file I have printed hundreds of on this printer in the past. Help!!!

Hey there, i have a Lot of ghosting. I am Not Sure, But I think it's getting worse.
I allready tighten the belts, but Same result. Any Tips :/

Recently I've had an issue where my printer will shut off at any point. It could be immediately after I turn it on or it could be 4 hours into a print. Sometimes the printer will turn back right after it turns off. I've opened the bottom of the printer but everything seems pretty okay, doesn't seem like anything is burning out. The strangest thing I've found is the power button has some resistance when trying to turn off the machine.

Any ideas what could be going on?

I checked the wires and everything looks fine. The output voltage from the circuit board to the heat bed jumps around and is not a steady 12V. Is this PWM maybe or should it be 12V steady. Does anyone know?
If the voltage is normal I'll check the continuity to the heat bed to be sure it is not the wires.
Also is there a way to test the heater. Should the wires give a certain resistance?

Any help to trouble shoot and fix this issue will be appreciated. Thanks.
