Does anyone have any screenshots or listings of their Repetier
settings they could share? I have a server set up but there are a lot
of variables for the printer, I'm having problems with the first layer
not sticking and am unsure of how/where to specify extruder speed,
print speed etc. The head is zipping around way too fast initially to lay down a track. The server does pick up some default values from the printer through a serial query but any documentation wrt the Select Mini is pretty sparse.
Cheers!

Ok while trying to fix a blockage I have ran in to an issue that the nozzles fitted the Malyan M200 are shorter than any thing I can get on line.

It seem to add about 2/3mm and that will make it impossible to level as I don't have that amount of movement in the bed.

Anyone used the longer nozzles, and what changes did you make ?

I have done it but it is a little tight, ended up winding the bed screws in (I have glass bed so higher than normal) 3 of the screws still have movement but one is on the limit. it may be better once i remove the painters tape between the bed and glass or a thinner bit of glass.

Try a different cable too. The one I received with the printer was really temperamental switching to one of my good quality cables helped.

I could not make a piece on the select mini that was solid when using the Cura 2.3 software. Make sure you have the Cura 15. That and the filament settings changed to 1.75 fixed the extruding problem for me! :)

I just got this printer and love it, but I have been having an issue with it. Every so often the extruder head will go all the way up and to the left until it reaches its limit and tries to keep going. then it just starts shaking and the only way to stop it is to flip the switch on the back to shut it off. What should I do to fix it?

it's happens to me too. It seems to be an issue that arises when starting a print after canceling a previous one. An immediate workaround is to simply cycle the power after canceling a print.

I am having an issue connecting my MP select mini to any computer using usb. I have used multiple usb cables and updated the firmware to the most recent release. No computer is recognizing the printer. Anyone have any ideas? Should I reset the epprom?

The web interface will at least work, as long as you can get pronterface aka print run to work normally on MAC and install the Malyan link I provided all hunky dory, trust me there's no doubt you will be able to print wirelessly with little to no issue on the ui.

NEW PROBLEM i had an issue with my printer earlier today but before i could read the comments my printer got into a new problem witch i did not realize before... my printer will not turn on. if i move the bed or head slightly the lcd will will flicker (that's if its plugged in) if it isn't plugged in than neither the fan, lcd, or knob will light up. i tried that reboot where you slide the x y and z axis to their home states and hold the select button while your are turning it on but that does nothing. like i mentioned before in my other post if i cant find help i have a warranty on it until jan 30 but if someone can help that would be really nice.

Hey guys I just got this printer and love it. The only thing I do not like is the small bed size. I would like to upgrade it and make it larger. I am limited on the prints that I can do. Is it as simple as upgrading the x axis rod? Thanks

Continuing from my attempts to calibrate the printer that went wrong, after resetting I still trying to get back to a stable status, since the re-flash and reset of the EEPROM, I have ran through the auto tune for the bed (50c) and the Extruder (205c).

I'm still having two issues:

1: Oozing, I have tried temp from 195c to 220c, I have tried retraction distance from 2.5 mm to 5.4 mm but it has not improved.

2: Structures are weak, the layer are not coming apart themselves but with little pressure they are snapping off or coming apart, E.G the smoke stack on top of the Benchy can be knocked off with little effort, other structures can be separated with a pair of pliers.

Thick structure seem OK but if I can get leveridge the walls will peal off.

Any ideas?

The fan just needs to cool the throats that's all for now. You can keep whatever fan is on it as long as there's no cooling whatsoever on your part going to the printer object. This is to eliminate all possible variables on the machines part, then we can move on from the environmental part. Yes the extrusion multiplier. If it was set at 90 as of the print you showed today, then do a 70 percent flow rate. If not then do 80. This is only temporary though, just to see if the steps are off because to me they look miles off haha

The thermistor in my printer has broken now . . . twice. I've looked all over the Internet for instructions on how to replace this because, from what I can see, the wire is just left hanging inside a hole in the hotbed, held in place by the plate that's screwed on.

Now, don't get me wrong. When I installed a new one, I just put that end in the hole, screwed down the plate, and it worked just fine . . . for about a week.

I'm just trying to figure out if I'm doing something wrong with the thermistor installation. Has anybody got a tutorial or anything?

+Matthew Upp saw that gadget but I'm having the opposite problem. My bed bows up in the center. I'm thinking if I can put a fifth screw in the center I can hold it where it's supposed to be.

i have owned my Monoprice Mini since August (this is my second one, first died within 30 days so back to Amazon).

This one suddenly can't get through a print, it stops and then starts the gcode file over again from the beginning. I typically print from SD card, it won't even print a file that it successfully printed before. Sometimes it will print 10 layers (and restarting is a catastrophy) while other times it will not finish printing the brim before it restarts.

What are the internals of this printer? Is there an arduino in there? Can you do your own arduino build? How does the display driver work?

My point is, if I need to replace the arduino can I reflash it? I don't see drivers on the Monoprice web site.

Regarding the website, the reason I started it was to be able to copy and paste links to make it easier to answer questions that are specific to the Select Mini. I don't have to much troubleshooting info for the general 3D printing problems because most 3D printing problems have the same fixes no matter what printer you are using. For example, clogged nozzle, first layer related problems, extruder clicking, curling, and stringing to name just a handful of everyday problems that go along with 3D printing.

What I didn't think about was the Select Mini would bring a whole new audience to 3D printing. This may be because they had no interest or thought they couldn't afford to have interest in 3D printing. Now that these fairly impressive machines are available for $200 ± $30 many more people can afford to spend the time and money to get involved and learn the art. I was blind to the need or maybe want is a better word for beginners tutorial videos because there are so many out there already. But having videos that that feature the exact printer the consumer is using probably does make a video more appealing to those people. I definitely see the value but unfortunately I didn't see it until later.

For the MP Delta Mini site I plan to make it be for everyone as if they have never used a 3D printed before. In a way this will be true for most Delta Mini owners because of the Delta's somewhat unique style of laying down plastic. Not entirely different but being the Delta Mini will be my first Delta style printer it will be easier for me to document the first steps to the last. For now the Delta Mini's site is forwarded to the Select Mini site but hopefully in a couple or few months I will be able to start putting content together.
(Oops I may have went on a tangent there)

Look up bridging calibration on thingiverse. There's a bunch of quick parts to test with different settings. Different brands and colors yield different results

Yes the standard mk8 has longer screw. It's twice as big so you will want to find a short screw length.

Hello for the holidays I got an mp select mini as a present from my dad. I've gotten about four or five very smooth and good looking prints but now when I try to print something it will shut off mid print or in some cases restart mid print and waste a lot of filament... I have a warranty on the printer until Jan 30 but if someone can help me that would be super awesome.

Being your prints are restarting I suggest updating the motion controller firmware to version 26 or higher.

I recently bought a Monoprice Mini and have printed a few things quite smoothly over the last few days. However I thought I'd update the firmware as I had seen it suggested on many sites, this resulted in the thermostat for both the extruder and platform always reading the same temperature (266°). As a result, it is refusing to heat as it thinks it has already exceeded the target temperature(s). I have since downgraded the firmware back to stock, though this did not solve the problem.

Has anybody encountered an issue like this?

Open up the machine make sure there are absolutely no shorts on the thermistor connections for both the extruder/hot end thermistor and the heated bed thermistor. I bet you that is what is going on, because the value of 266 is awe fully close to the c language PWM switch of 255, and the extra value of 11 usually is from the offset that is programmed from the machine itself as I have seen before. Check those connections/thermistors themselves too if you need to. There has to be some sort of short/loose connection. It looks like the positive/signal pins are touching or are broken somewhere. Or it could be another source, say, one of the positives from a motor connection or LCD connection or something could also be hitting the signal pin. Let me know if this helped, good luck!

Hi, I just received a monoprice mini for Christmas. Printed one demo, turned out great. Tried to print something else and got a clogged hose. but in the process of hitting the home button, the head wants to hit the side of the printer. any suggestions on getting it to the home position without the loud grinding noises? Thanks in advance.

Your fan gets in the way, move the fan to the right a bit. That's a common "grinding noise" (not hitting limit switch) issue after disassembling the printer extruder. You can manually shift it with your hand, unclip the fan and reposition if needed
