Trio of Mods Makes Delta Printer More Responsive, Easier to Use
1 min read
Summary
Delta 3D printers, such as the Anycubic Kossel, have three axes with the effect of creating complex movement for the extruder head, thereby creating complex 3D shapes.
While they are aesthetically appealing to watch in action, the design can present some problems, including positional accuracy and repeatability.
In order to mitigate these problems, as well as resolve some personal annoyance with the stock z-probe, Bruno Schwander made several modifications to his printer.
These included switching the hot end for a smaller MQ Mozzie and replacing the original fan with a lighter remote brushless motor, connecting it to the hot end via a light nylon fabric duct.
Schwander also created a replacement for the z-probe, using a 3D-printed spacer ring and twelve strain gauges, connected to an Arduino and HX711 amplifier to send a signal to Marlin when the extruder head touches the bed.
