In early April, a member of the Prusa i3 Facebook group posted about a feature of Marlin firmware that they had come across named linear advance. Documentation for the algorithm can be found here. In a nutshell, LIN_ADVANCE enables a pressure control feature which sets the pressure inside the nozzle to the needed one according … Continue reading Linear Advance
A new extrusion system
As it stands right now, there are two main extrusion systems - bowden and direct drive. Each comes with its own advantages and disadvantages, which is the reason why both still exist. The main disadvantage of direct drive is the higher moving mass, which is the reason why the bowden system was created. By moving … Continue reading A new extrusion system
All about “layer seams”
I've recently been researching a lot about methods of reducing the visibility of seams in 3D prints. Commonly referred to as layer seams, z seams, blobs, zits, or scarring, the marks appear on prints either in a line or scattered around the model depending on slicer settings. An example can be seen below on this … Continue reading All about “layer seams”
Designing a custom logo stamp in Fusion 360
In search for a unique way that I can brand the packaging that I send out to my 3D Hubs customers, I came across this video by Devin Montez on his Make Anything Youtube channel. After watching this, I decided to design and print my own stamp. This post will cover the design process, and the post … Continue reading Designing a custom logo stamp in Fusion 360
Prusa i3 MK2 V2 Calibration Bypass
Here's a quick little fix if you want to set your live z adjust value on the Prusa i3 MK2 without running the V2 Calibration, after performing an XYZ calibration. Doing an XYZ calibration will clear your stored live z value and require you to re-run the V2Calibration.gcode file provided by Prusa Research. If you tune your … Continue reading Prusa i3 MK2 V2 Calibration Bypass
PID Tuning
PID tuning is a fairly quick and easy process that can make a big difference to your print quality. If you can see while you're printing that your extruder temperature is fluctuating up and down by a few degrees then a quick PID tuning can help to make it rock solid. Temperature fluctuations can even … Continue reading PID Tuning
Printing multiple colours or materials using a single extruder
If you're looking to change colour or materials part way through your prints, the best way to do it is with an M600 command placed in your G-Code. If you're not using z-hop in your slicing software and you'd just like to change colour, you can easily insert the M600 command wherever you'd like in … Continue reading Printing multiple colours or materials using a single extruder
