After doing some research, the first thing I purchased after the printer was a MOSFET module to modify the power supply. While optional, this modification was HIGHLY recommended by everyone due to the fact that this particular version (v2) uses a 12 volt power supply versus the newer 24 volt supply. Apparently the lower voltage strains and overheats easily when driving the axis motors, extruder, and heat bed, resulting in a severe fire risk for long prints. To make the installation super clean, I printed a mounting bracket that fits perfectly inside the case and holds the MOSFET module in place.
While searching through the Thingiverse website, I came across another modification for the power supply; a 120mm fan upgrade. I first printed out the cover adapter which extends and slightly expands the back of the power supply. I next printed out the fan grill. Finally, I routed the wires and mounted the adapter, mounted the fan, and then the grill. Not only does the larger fan perform better with more airflow, it is much quieter than the original 40mm fan.
I personally haven’t experienced any Z-axis ‘wobble,’ but it is a known issue for larger/taller prints. I came across the “Z Brace Yourself” package that included several brackets to attack to the base of the printer as well as on the Z-axis tower that uses threaded rods to firm everything up.
While I was waiting for the printer to arrive, after some reading, I decided to pick up a new aluminum heat bed to replace the stock one. From what some people were saying, the original hardware is a lighter gauge and was prone to warping. I was also going to add a glass plate top using a thermal pad, but I haven’t experienced any issues, so that will be a project for a later date.
Everyone has different opinions on what type of printer filament to use; brand, type (PLA/ABS), etc. For my application, I selected the Tianse brand that I purchased from Amazon due to the number of reviews and high marks. As of this post, I have over 50 hours of printing and really haven’t experienced any issues with the media itself.
