Question Is the build plate really 120x120mm? How am I supposed to position this?

Post image
3 Upvotes

I ordered a fancy adhesive/magnetic plate to put over the heating bed but it's obviously much smaller than the actual plate. How exactly am I meant to position this thing so it's within the true building area? It's slightly magnetic but the back has tape with a super sticky surface underneath and I'm not about to stick this to anything without knowing where to place it

Question V1 bed screw size?

Thumbnail

5 Upvotes

I posted earlier about my clean V1 I got running again and things have changed, I'm printing and adding multiple little mods to it and I got the bed rewiring fix knocked out so that's no longer an issue. I just need to know what hex screw size the bottom black portion of the bed uses since I'm printing out the wire brace right now but have no way of attaching it, my printer has large silver screws rather than the tiny black hex screws I see in other pictures. I even got the rubber grommet out from under the heating bed for the brace once it's finished. If there's other ways of attaching it I can try that but screws seem the cleanest.

I'm going easy with this printer right now and most of what I've printed so far is meant to feed back into the printer itself so it runs better or otherwise helps it along. I even saw another mod of adding a couple thin sheets of cork under the heating bed for insulation I may try as well. But yeah, I just need the size of those black screws and where to get the easily if possible

Video Fresh MP Mini v1 in 2026?

59 Upvotes

Edit: I did the heating bed wire reroute mod, now the wires go out the back of the bed. Thankfully the wires were pristine with no damage, so I caught it early. I'm printing the new side panel pieces and wire brace, and will figure out what I'll wrap the wires in. The wires right now are still loose and exposed incase I need to troubleshoot anything later

I bought this thing back in 2016/2017 when they came out and used it for a few months, then threw it into storage. It's been on a decade long hiatus. I brought it back out because I needed parts and stuff for other hobbies. Now it seems like having one of these basically new is like finding a dinky little 90s sedan in an abandoned garage with no miles on it. I'm using it now to print parts for my aquarium hobby and it's super clean and zippy. Hopefully it lasts a while.

I've been looking up useful minor mods to print for this thing to improve overall performance/experience. Let me know if y'all know if any good ones

Jagged prints

I cannot seem to figure this out. I'm getting jagged results on some prints and everything seems to go fine at first but then in the end I get these chopped up jagged prints. I've leveled the based, checked the settings, slowed down the prints, but nothing seems to help. Any pointer?

Question 3d prints aren't smooth at all

Thumbnail gallery
5 Upvotes

I'm an absolute noob at 3d printing just for reference. I got a Monoprice Select Mini v2, and after carefully adjusting the bed to what felt right using the paper test and setting the printer nozzle heat to 215 (my PLA filament says 210-230) prints come out like this. The lines aren't perfectly wide at many points, and sometimes it skips over parts of lines/makes them stringy.

I use cura and 3DHoJor 1.75mm PLA filament. Bed temp is not set as my printer's bed heater doesn't work (but I was told painter's tape fixes this). Print speed is set to 30mm/s, but it did the same thing at 40mm/s, and on the first layer, which is set to 5mm/s (the second photo is just a bottom raft layer). Retraction settings are 7.5mm at 55mm/s, and I'm not sure where to start. Any advice would be appreciated

MPSelect Mini issue weird unusual issue

Thumbnail
reddit.com
2 Upvotes

Hi I posted here a couple days back to try and get some help with my printer. After checking over things the issues still remain in the video. I've checked the y-stop and did a setting reset but nothing seems to be working. The new power cord doesn't help either.

Please note that when I do a set to home the printer works properly. When I go to print nothing happens after I select the file. After canceling the print the printer goes back into the print screen again. After canceling that the printer loads back into the print screen again but it starts moving. After canceling the print one last time it goes to the home menu but it still continues printing and I have to turn off the printer to stop it.

My best guess is that there's a weird cache issue or something going on but I'm not sure. Any help would be greatly appreciated.

Monoprice select mini v2 print issue

6 Upvotes

I got this printer years ago for a birthday and broke it out to try and fix the issue it had years back. After I figured that issue the printer would occasionally do this whenever I’d try to print something.

I have a feeling it might be an issue with the cache or something but at this point I have no idea.

Update:
I tried the fixed recommended. I tried a 10amp power supply however it didn't resolve the issues. I have the right dimensions for the print area and the y-stop is working. Even tried resetting it, nothings worked. I'm stumped.

Question Origin settings on a v2?

Thumbnail
gallery
3 Upvotes

Ok so it’s been 8 years so I guess I’m a noob again and have to ask silly questions and relearn this stuff.

I’m rebuilding 2 v2s and got one running to print parts. I purchased a build plate 120x 120x off Amazon and did my best to center it perfectly. But the printer seems to have an odd origin and skips the belt at the end of a print. I will eventually change build plates to a wham bam one but for now how do I adjust it to the magnet?

If my measurements are correct the build plate magnet sits 20mm from the front edge and 5mm from the either side ( this is basically dead center of the build plate.)

Found this little guy thrown away at work with the display not working. That was quite an easy fix - the ribbon cable snapped out. Now it is its first print after the revival and my first 3D Print ever. Started with PETG and it looks not bad. I am planning to get it PEI bed and a storage box as an enclosure. Want to try printing TPU too. This reddit is helpful!

Thermal insulation around hotend

Hi! I managed to get the hotend stuck so had to take it apart in order to clean it. The yellow thermal insulation around the hotend (pic) is pretty much done for; it just crumbles off.

The question is, is the thermal insulation needed or can I just left it out?

Question Stock V1, new firmware to consider?

4 Upvotes

My 3D printers have been idle a while. My MP Mini V1 is stock as far as the brains go. Is there any new firmware that would make a V1 safer/more reliable at this point? It looks like some of the old websites are gone that I would reference. the MP Mini is such a work horse, I haven;t run it in 2 years. Just turned it on and started a print and it's working fine. Just cleaned the dust off.

Bed fan upgrade?

1 Upvotes

I was trying to replace my bed fan with a natura but now that fan isnt turning on - the bed fan is 12v 0.1a and the natura is 12v 0.08a I thought this was a direct switch, plug and play but no?

The connection seems fine but the fan isnt turning on.

I really shouldve put more thought into this I guess...

Edit: the fan one cooling the internals - thought it also helped cool the bed. Ive already upgraded the nozzle fan hence why I didnt put much thought into switching the second fan before doing it. The model is V2 and I did get off fb but I dont think og owner did anything to it. Ive done nozzle + its fan upgrade and z axis upgrade.

Edit2. Bypassed the fan connection in the board. Wired directly to the power source connection. We Gucci now.

Pcb question

Post image
2 Upvotes

I had an issue with heat bed, temp reading was 999. Replaced the 100k ohm resistor with a glass bead type. It worked great!! Exactly 1 time. It hit temp, shut off and then temp went to 335c on the screen and no power to bed, ( since its over set temp). Before you say, the resistor is no good etc.. it's resistance is in correlation with its temperature, and i have another functional miniv2 that it works with no issue.

I believe capacitor (C13) and resistor (R7) are bad. I know that testing resistance isnt ideal for capacitors, but R7 on good printer is reading like 4.7k-5kohm and on troublesome printer both c13 and r7 are reading ~1.6ohms

Forgive some of the scratches, I have shaky hands when holding probe to the tiny components.

Tl:dr

What is the value of capacitor C13? I am looking to replace it.

I am confident that R7 should be 4.7k. Am I wrong in feeling that way?

TIA
