Connect to your RepRap Wirelessly or Via the Internet Using the HLK-RM04

DSCN4390Recently my attention was drawn to a UART-ETH-WIFI module (serial port - Ethernet - Wireless network) that is incredibly cheap and incredibly flexible.  I have been playing around with it and have managed to use it to connect my Reprap printer to a wireless network.  It have it tested and can confirm that it works between Pronterface and the RAMPS board running Marlin firmware.  What is cooler still is that with a little port forwarding I can upload files and control my 3D printer from anywhere in the world!

It took a little fiddling around to achieve this so i thought that i would produce a simple guide for anyone who wants connected!  This guide uses software designed to work on Microsoft Windows, though I am sure that Linux and Mac have equivalent packages that could also be used.

Simple Heated Print bed Levelling for RepRap Printers

Since building my first RepRap Prusa V1 printer over a year ago, I have been gradually updating the machine, improving it’s print quality as I go on.  One of the areas that I have managed to improve upon quite a bit is the y Axis of the machine.  The original Prusa had a fairly complex sprung print bed which was less than ideal.  in order to improve upon it I both used ideas from the V2 Prusa and developed my own very simple adjusting mechanism to all but eliminate backlash in the Y direction.  Here is how.

Attaching a LCD display and Rotary Encoder to a RAMPS Controlled RepRap Printer

IMG_20120228_235610I have been more than a little quiet on the website, mostly because of the birth of my son and the busy busy lifestyle that goes alongside such an event.  However that does not mean that my soldering iron has been allowed to go rusty.  For the last few months I have been busy building a RepRap  3D printer.  This is a popular project these days and one that has been rewarding and challenging to me.

The printer that I opted to build was the Prusa Mendel, named as such in recognition of the designers.  Building the printer is a story for another article, but in this I want to show you how to add a LCD/Rotary Encoder based control panel to the printer.
