Z-Wave: Controlling Light with a motion sensor

Fibaro Motion Sensor


Z-wave modules offer great flexibility and a relatively inexpensive way for automating just about anything in your home, from lights to the garage door. In this article the installation process for a light operated by a motion sensor is covered. This is one of the most basic applications of Z-wave automation and might be a good project to if you are considering to start with Z-wave.

Dual Nozzle X and Y offset calibration on Flashforge Dreamer

When using a dual extrusion printer it is important to calibrate the distance between the nozzles in X and Y direction. A properly calibrated printer will produce parts without a visible shift between sections printed with the left and the right extruder. In this article I wil discuss the use of a calibration program to find the offset between the nozzles on the Flashforge Dreamer.

Controlling S&P inline duct fan with a Qubino ZMNHAD1 Flush 1 Relay switch

This is a short guide on how to install an inline duct fan and a z-wave enabled switch to control the fan.


Any bathroom benefits from proper ventilation, which helps to prevent mold and excessive humidity levels. For my bathroom I decided to use an inline fan, which is typically less noisy than a ceiling mounted version. Trading in a humid environment for a noisy one did not seem like a good plan. Continue reading “Controlling S&P inline duct fan with a Qubino ZMNHAD1 Flush 1 Relay switch”

Slic3r settings for dual extrusion prints on Flashforge Dreamer

As anyone who owns a 3D printer knows, it may take some of trial and error to obtain good print results. This is especially the case for dual material prints. The Flashforge Dreamer supports dual material printing out of the box. However, I have noticed it can be hard to print parts without color mixing due to oozing extruders that wipe themselves clean on the edges of the part. In this article I will describe a method to use dual extrusion with Slic3r, which significantly improves print quality. Continue reading “Slic3r settings for dual extrusion prints on Flashforge Dreamer”

Slic3r G-code for dual extrusion printing on the Flashforge Dreamer

In this article the complete configuration of Slic3r for use with the Flashforge Dreamer is discussed.

Slic3r is a great freeware program for slicing your prints and includes numerous options to tweak print settings to your liking. However, in order to work with the Flashforge Dreamer it needs to be configured to output G-code that the dreamer understands. Also custom G-code can be added at the start and end of each program automatically, so files generated by Slic3r can be used directly on the printer without any modifications. Continue reading “Slic3r G-code for dual extrusion printing on the Flashforge Dreamer”

Flashprint advanced print settings by editing the default.cfg configuration file

Flashforge supplies its printers with their own slicing program called Flashprint. It is compatible with the Flashforge Dreamer, Creator Pro, Finder and Guider 3D printers. The software is easy to use and contains most of the features required for everyday use. However, programs like Slic3r and Simplify3D offer more advanced options for situations where the standard settings do not deliver the desired print quality.

If you do not want to invest time in setting up or buying a different slicing program there is also a way to change quite a lot of advanced settings within Flashforge’s own Flashprint program. Continue reading “Flashprint advanced print settings by editing the default.cfg configuration file”

Honeywell Evohome User Review

There are many smart thermostats on the market, but the Honeywell Evohome system stands out in its ability to control the temperature in multiple zones independently. This is what makes the system a lot smarter than other thermostats. Of course there is also an app to control temperature of each zone remotely.

In this review I will discuss my experiences with the Evohome system since I installed it at the end of 2014.

Install all metal hotend on Flashforge Dreamer and print test with PC-plus Polycarbonate


As delivered from the factory, the Flashforge Dreamer can print plastics like PLA and ABS, but more demanding plastics like Nylon and polycarbonate are out of reach due to temperature limitations of the hotends. This article covers the upgrade to metal hotends and a trial run with the new nozzles using PC plus polycarbonate filament. Continue reading “Install all metal hotend on Flashforge Dreamer and print test with PC-plus Polycarbonate”

Flashforge Dreamer PLA Turbo Fan Installation

In this post the installation of a PLA Turbo fan on the Flashforge Dreamer is described, including the benefits for printing with PLA.


As discussed in the Flashforge Dreamer review posted earlier, some of the Dreamer models did not come with a nozzle fan fitted on the side of te extruder carriage. My specific printer was only equipped with 2 larger fans mounted on the back of the printer.

PLA should be cooled as quickly as possible after leaving the nozzle in order to obtain the best results, especially in challenging situations, such as steep overhangs. Continue reading “Flashforge Dreamer PLA Turbo Fan Installation”
