OpenBuilds. Bellows. The linear slides I got off ebay didn't come with covers to stop swarf getting to the rails and ballscrews.


So I decided to cover them with a bellows. I did a little bit of research. There are some stock sized commercial bellows available; these are usually rubberised fabric, welded at the seams. I couldn't find any that fit, nor could I afford them. So I googled for DIY bellows folding. Patent number 6,054,194, invented by Nathan R. Polypropylene sheet was selected to make the bellows. Building the Bellows 1) Print the fold pattern The first step is to produce a fold pattern for the bellows. The program will only create a fold pattern for a simple bellows with either regular or alternating folds.

The parameters are... The program will print out the fold pattern. The image below shows a snippet of the fold pattern. The picture shows the fold pattern with a sheet of clear/translucent polypropylene on top. The program and source can be downloaded here . 2) Trim 3) Score the lines 5) Folding. UHU Servo. This is our version of the AVR microcontrolled UHU servo board designed by Uli Uber.

UHU Servo

It is a brushed motor controller with step/direction interface. It is capable of 250,000 steps/second for fast motor rpm. More information about the servo controller can be found at Uli's web site FAQ , Wiki page, our FTP site and this CNCZONE thread. UHU Servo Uhu servo boards are now available. UHU Servo schematic (.pdf), layout (.pdf) and parts list (.pdf). Specifications: Atmel AVR ATtiny2313 microcontroller based. Other features that we have added include: Smaller sized board than the original UHU version. Also available is a parallel port breakout board and is compatible with our opto-isolated breakout board.

*UHU board has only been tested with IRF540N FET's at 60volt/20amps. Dimensions: 3.75" x 3". Power requirements: Requires external regulated 12volt DC supply. Price: Bare PC Servo board: $10 each. The preprogrammed AVR microcontroller must be purchased directly from Uli Huber. Back to home. Emc2Arduino. Well, after looking around for a good non-blocking multi-instance stepper library that has hooks I can exploit with input speeds from LinuxCNC (a very tall order) I found one that could do it.


AccelStepper, so I put my coding hat on, brewed some coffee and banged out rough implementation of HAL2Arduino 0.4 (the preRelease version). For those of you that have been waiting ever so patiently for the next generation of EMC2Arduino, here is the first version of HAL2Arduino that is actually useful to the average end-user. This version has a couple of bug fixes: Bi-directional communications fix.

(Coding typo)Init spam bug fixed. Added features: Support for plugin based mod files, for drag-n-drop/compile add on features.Pre-compiler optimized code (modFiles too!) Added modFiles: In the pipeline: modButtons: A control panel collection for the basics like E-Stop, start, stop, pause, step, etc. If you like, you may grab an early copy of it here. jCNC - CNC Steuerung. jCNC ist eine Software zur Ansteuerung von CNC Maschinen über einen externen Maschinencontroller.

jCNC - CNC Steuerung

Die Kommunikation mit dem Maschinencontroller erfolgt über USB. Die Software verarbeitet Standard G Code. Dieser Code kann in einem Editor, mit Syntax Highlightning, erstellt, bearbeitet und parallel 3D visualisiert werden. Durch die zeitgleiche Visualisierung kann man den erzeugten Code sofort kontrollieren und entdeckt somit schnell Fehler in dem erstellte CNC Code. Die CNC Steuerungs Software "JCNC" habe ich speziell zur Kommunikation mit dem ATmega GRBL CNC Controller Board geschrieben, sie sollte aber auch mit jeder anderen CNC Steuerung mit einer GRBL Firmware funktionieren.
