A recurring issue that I see often for many reprap 3D printers that have carriage-mounted fans is seeing the hotend temperature plummet when the fans turn on. The common scenario is printing PLA, which benefits from having strong fans cool […] ↓ Read more…
I’ve merged my Marlin modifications with a newer version of Marlin, in a new github repo. Status info GLCD screen for DOGM LCDs display Z coordinates to hundreds, not just tenths display SD print progress percentage numerically, not just with […] ↓ Read more…
In rare situations there is an issue that can cause your 3D printer running Marlin firmware to suddenly stop during a print, leaving you to troubleshoot without knowing for sure if you have fixed the cause. One of the first […] ↓ Read more…
I posted this on a Google group recently and thought I’d repost it on my own blog: I have been converted to an evil and lazy extrusion calibration anarchist. I no longer believe in measuring filament diameter or how much […] ↓ Read more…
I’ve been running my fans in this orientation for several days and results are much better with more control than any other method I’ve tried. The airflow is much more even than previously and I was able to add insulation […] ↓ Read more…
This is an example of a typical and simple home repair solution when a 3D printer is available. Instead of replacing an inexpensive small mirror or attempting to recover and glue the broken pins that attach the mirror to its […] ↓ Read more…
I’ve started a photo gallery for the objects I print as I continue to test and tune my MendelMax 2.0 3D printer.
So although my MendelMax 2 beta2 has only minor Z wobble visible in the prints as long as the leadscrews are not constrained at the bottom by bearings, I wanted to completely eliminate the wobble from appearing at the nozzle. […] ↓ Read more…
This is a quick prototype of a pierogi press I designed using Alibre, the first time I’ve done a multipart confined assembly, where the moving parts are printed in-place locked together. The hinge pins are printed inside their holes so […] ↓ Read more…
I often see confusion by people in IRC about how to disable and enable endstops so that accidentally sending a home command (G28) doesn’t cause their printer to crash an axis past it’s physical range. G28 is a command that […] ↓ Read more…
