Converting a Proxxon MF70 Milling Machine To CNC – 4 using PIC24FJ64GB002

At the start of this series of posts, I said I did not want a PC to control my Milling Operations, so some local delivery method of supplying the gcode files is required. Having said that, the system is ‘open’, and a simple XON/XOFF terminal program running on a PC can be used if required. G-Codes can also be typed in on a terminal keyboard, though this method could prove tiresome with even moderately-sized ...

Converting a Proxxon MF70 Milling Machine To CNC – 2 using PIC18F4620

My layout is shown below. It may not be as intuitive or informative as the layout on a PC display, but contains everything I have found necessary for control of the Mill. (and previously the DRO’s on my other Milling Machine and Lathe.) I should stress here, that this is an overlay – i.e. a plastic-faced, easy-to-clean front which has a cut-out for the LCD display on the left, space for ON/OFF switches and ...

How to make a contact-less digital tachometer using IR-light reflection technique using PIC18F2550

Tachometer is a device that measures the rotational speed of any shaft or disc. The unit of the measurement is usually revolutions per minute or RPM. The traditional method of measuring RPM of a rotating shaft was based on velocity feedback concept where a dc generator is hooked to the rotating shaft so that the voltage induced across the generator’s terminals is proportional to the speed of the shaft. Toda ...
