Monoprice Maker Select V2

Product page: https://www.monoprice.com/product?p_id=13860

I believe that this printer delivers great quality for the price - so far it has consistently exceeded my expectations. Assembly and setup were painless, calibration was straightforward, and before I knew it I was up and running.

Print Settings

I primarily use Cura for slicing. I added the Maker Select V2 using the Prusa i3 printer profile, making sure to reduce the maximum Z height from 200mm to 180mm. Most of my printing is done in draft quality at 0.2mm layer height. I found that with the default settings, not only was I slightly annoyed with some quality issues, but I would also suffer plate adhesion problems. Changing from brim to raft type plate adhesion solved the latter problem entirely. For the quality issues, I found that reducing the print speed allowed me to get consistent, high-quality results. I've added the custom settings below.

Custom print settings:

• Print speed: 50mm/s
• Outer wall speed: 15mm/s
• Inner wall speed: 30mm/s
• Top/bottom speed: 20mm/s
• Travel speed: 80mm/s

Mods / Customization

The Maker Select V2 is a solid printer stock from the factory. But it's not without room for improvement.

• Z-Axis Braces
  • Braces that stiffen the Z-axis tower to prevent wobbling.
• Z-Axis Extensions
  • Though the Maker Select V2 is said to have 180mm clearance in the Z-axis, the truth is it's about 143mm. These extension blocks make up for that difference.
• Upgraded Fan Ducting
  • This design allows for better airflow. The end result is higher-quality prints.

Here's some of the prints I've made.

• 

  A failed Yoda print. You can see the infill grid in the space left open at the top, and the brim around the bottom edge.

• 

  A cup made to look like Bender's head is in the middle of printing. You can see the infill grid in the space left open and the raft underneath. (PLA, 0.2mm layer height, 10% infill)

• 

  A black cat head planter. This print was made with 100% infill, so it's solid plastic. (PLA, 0.2mm layer height, 100% infill)
