Quick tutorial on using the Tormach Digitizing Probe and Mach3 to digitize a part. Blender, a free software, is used along with a couple Python scripts to enable the digitization. Enjoy!
This code is a script for importing points from the Mach3 Digitize Wizard to the Blender Environment. The code below should be copy and pasted into the Blender “Scripting” Window. Once pasted the path needs to be changed in the … Continue reading
The solder reflow oven controller is nearly finished. The previous post showed the milling the circuit board, now the enclosure box has been finished. The design consists of an Arduino Uno R3 microcontroller which monitors the temperature of the oven, … Continue reading
A printed circuit board was designed by David Cannistraro. The circuit is used for control of a toaster oven converted into a solder reflow oven. Once finished the circuit will control the heating/cooling of the oven while monitoring temperature inside. … Continue reading
Months have gone into the production of an enclosure for the Tormach PCNC 770 mill and robot. The goal of the project was 1) enclose the mill for safety purposes (also keeps chips off the floor) 2) Make a stand … Continue reading
Joe Schmitz, an undergrad mechanical engineering student at the University of Iowa has been working a with the Tormach mill. He created a few dice on the machine.
I have been busy designing an enclosure for the Tormach mill. Originally I designed a single-hinge swinging door for the enclosure, but I have worked on mills with a swinging door before. It seems once the door is covered in … Continue reading
For a demo the Tormach mill was used engrave 1.7″ diameter x 1/8″ coins with the University of Iowa seal. Tool: engraving cutter (1/8 x 1-1/2 half round 90 deg) Depth of cut: .005″ Spindle Speed: 8500 RPM Feedrate: 18 … Continue reading
