Blocks tracking from browser and apps

Opensource ad blocker for Android that filters all outbound requests for ads and tracking using any combination of premade lists, whitelist and blacklist. You can also switch dns providers by selecting from a list or adding one. UI is simple and effective.

Blokada works by using Android’s vpn feature to route all outbound requests through it. This allows it to filter all requests that come from the device.

Verdict

This is a must have app for Android.

Does the job, paltry linux support

Desktop thermal transfer printer with UPS Worldship support. These things are reliable, printed several labels a week for a few years after buying it used.

Linux

Linux support is frustating but completely fixable. The printer will print out of the box with Zebra ZPL print driver. The prints will look poor and barcodes will be terrible and likely unreadable. The fix is to use the CenterOfPixel option when printing :
lpr -P printer -o CenterOfPixel pathtofile.
Prints will look just like they do on Windows. This should be possible to add as default in the .ppd file in /etc/cups/ppd for this printer, but it hasn’t worked for me yet.

UPS

Printing UPS labels from a browser using UPS Thermal Printing Script requires the printer is setup with a raw queue. When adding the printer, click on generic driver then raw. Print normally and the script will take care of the rest. Label prints perfectly.

Verdict

Printer is dead reliable, points off for poor linux support.

Needs tweaks to reach potential

Monoprice Maker Select V2 is a near direct copy of a Wanhao Duplicator i3. This printer optimizes the i3 design for mass production using steel sections for the frame and electronic housing. Notable for coming nearly assembled and the low price(269.99 as of 11/2018).

Assembly

Involves screwing the steel upright to the x axis and running some cables, quite easy.

Components

The steel frame is quite sturdy, better than Original Prusas on the Z axis. Bed works well at first, but you’ll find the adhesive surface on top wears out rather quickly and entire bed assembly is poorly designed. Spoolholder is basic and too small for spools from Monoprice.

Printing

Tested with Monoprice PLA, printing went well at first with suprisingly good print quality. Over time, printing becomes more frustrating. The bed surface will need to changed frequently if printing regularly. The bed has become less true forcing me to use rafts and only use a 2"x2" square in the middle of the bed to get quality parts. Dimensional accuracy in the X and Y axes seemed to suffer scaling issues where it would undershoot dimensions.

Software/Firmware

I used Cura and Repetier to slice and control the printer. I recall everything working fine once setup. I had to pull printing profiles from the gcode on the sd card that came with the printer. The printer size and connection details had to be filled in to the host software. Acceleration/jerk limits were terrible, the frame would develop z wobble sometimes even though the frame is overbuilt to the point this shouldn’t be an issue.

Tweaks

There are many suggested fixes included for the common bed leveling issue. Locknuts for the thumbscrews, sturdier x axis carrier and replacing the bed with a PEI build surface. Also, a I’ve seen a MOSFET mod recommended as there’s reports the bed heater can overload a connector and possibly start a fire. Reportedly, implementing these fixes will make this a good printer.

Verdict

This is a decent printer for playing with 3D printing at a low price. If you want it to be a reliable machine, you’ll need to tweak many things to get there.
