Anet A8 – Budget 3D Printer Kit

I picked up this Prusa i3 inspired 3D printer for £139.81 (GBP) from gearbest.com. It has been really useful and has seen plenty of use in both my personal and University projects.

Not only that but it has been used round the house too. By the second day of having this printer up and running, I had already designed, printed and fixed the knob that turns my shower on and off.

Since then, the printer has been busy printing out a number of useful mods created by some talented CAD designers over on Thingiverse.com.

Please check out the first impressions & assembly video as well as the video covering the modification that I have done to this machine to increase its ease of use. The most useful feature being the mesh bed-leveling and warp compensation.

Auto-Leveling Sensor & Skynet Installation

 

You should probably download the latest version of the skynet firmware from the creator over on their facebook page. However you can also download my copy of the firmware (2.3.1 version) with all appropriate settings in the auto bed leveling section of the code.

Feel free to download my current print profile to use as a starting point. You may need to adjust the temperatures if you are not using a Buildtak print bed surface like I am.
