Z endstop mounting position.

I designed some basic endstop mounts for my MendelMax 2 beta1 using mechanical microswitches.

I designed a front panel mount using Alibre for my MendelMax 2 Alpha to control the Marlin firmware with the LCD and rotary encoder. The source files and STL are in My Files.

A short timelapse of a pixel-style version of the island of Maui, Hawaii. Printed in emerald PLA at .25mm layers in about 2 hours.

Ohmstruder NEMA17 Prototype Calibration

This is a first prototype derivation of my Ohmstruder modified to use a NEMA17 5:1 planetary gearhead stepper motor. This is the beginning of the initial calibration print to find the correct steps/mm using a calibration object. The object I use is a bearing holder that is printed in two halves that fit together with tight tolerance. When the halves are loose, more extrusion is needed. Calibration is perfect when the halves snap together easily but tightly. I’m printing this initial calibration test at 0.1mm layer height.

Another timelapse of printing a 3D vase, this one is from thingiverse 38532. Printed on my Reprap MendelMax 1.5+ with 0.1mm layers in Lilac PLA.

I did a simple timelapse of this Hyperboloid print in early 2011 and thought I’d do an updated one for the end of 2012 using my new processes on the MendelMax.

Applying PVA Glue to Glass

This is a demonstration of how I apply PVA glue to my glass print surface on my Reprap MendelMax 3D printer for printing with PLA filament. I can print PLA on bare glass for many objects, but for ones that are prone to lifting from the glass I use a coating of PVA glue which completely eliminates any first layer adhesion problems for me. I use a 1:10 dilute solution of PVA glue and water applied to the heated glass so the water evaporates quickly and I can control the thickness of the coating I apply. I can usually go for several prints without reapplying, depending on what I print. I usually set the bed temperature to between 50C and 60C for the entire PLA print and use fans on the nozzle and also across the build area.

Timelapse video improved

Hopefully the last timelapse of this vase object, but most of the kinks are worked out for the camera trigger and lighting. This is the same vase in Lilac PLA with 0.1mm layers and no bed heat.
