Calibration Cube - Monoprice Select Mini V2

Hi all,

I received a Monoprice Select Mini V2 for Christmas and have been having a blast with it over the past week or so. I've managed to do a lot of the recommended setup and through trial and error I have some decent prints.

Decided it was time to print the beloved Calibration Cube to see how well i am doing so far

Here are the results

​

My basic settings were

Material: Hatchbox PLA 1.75 in White

Layer Height: 0.175

Initial: 0.2625

Wall thickness: 1.5

Infill: Cubic @ 20%

Temp: 200 at print and 50 at bed

Speed: 35mm/s

​

Now to what I don't know. The X axis has visible lines and you can feel them when you rub your finger on it. Is this normal? I dont ever expect to have a glass like feel, especially with PLA, but I have no baseline here.

​

What about the Y or Z?

​

Any suggestions on what I can improve on or some settings to try?

​

Thanks!

I would suggest trying a layer height of .12 or .2. You're cube looks good, but using a layer height that is in line with the stepper motors helps me get 'smoother' walls.

Thanks for the reply!
I believe that layer height is in line with the MP Mini, but I could be mistaken as I am still quite new.

According to some documents and guides, it's "Magic numbers" are listed a bit different due to it's pitch and for this particular machine should be multiples of .04375mm instead of the regular .05mm

So this leads to values of

.04375
.0875
.13125
.175
.21875
.2625
.30625

For this one I chose middle of the range. I'll will definitely try with some of the lower ones so I can see the differences though!

It seems pretty good but like you said it looks like those layer lines are a bit too rough. Do other prints look the same?

For sure!

Here are some other prints with the cube in better lighting. There are a couple more prints in there, but they have some different settings than the cube. It was after the stand that I decided to do some more calibration. It turned out fine after a quick sand though. I have some more, but they are at home and these are all I had at work.

I did some of the recommended PID tunings as well on day 1. I might do some further extruder calibration/tests tonight after work to double check all of that though

Wow, those really don't look like 0.175. Have you printed a temp tower? These are my usual settings on an Anet A8:

Material: Hatchbox PLA 1.75 in Blue

Layer Height: 0.2

Initial: 0.3

Wall thickness: 0.8

Infill: @ 25%

Temp: 185 at print and 55 at bed

Speed: 50mm/s

Here's a link to something I've printed: https://www.thingiverse.com/make:431829

Edit: I've actually never done a temp tower I'm waiting on my new filament. 0.15mm not 0.2mm
