You will need a suitable Pic Chip programmer that supports the 18F4550.
This code is for use with the 18F4550 Pic Chip. Inside this file are two Gcodes, one for the Milling and the other for the drilling.ġ * 20mhz Xtal (the Pic internally clocks this upto 48mhz)ġ * little tactile push switch for resetting Pic, not really needed.Ĭlick here to download the Firmware Version 1.2 Type1: usb-par-firmwarev12-type1.zip Milling PCB below with 0.2mm engraving bit.Ĭlick here to download the Gcodes: usb-par-gcodev1.zip We are also releasing the PCB Layout in Gcode for people wanting to mill their own. These are 600DPI JPG and need to be viewed and printed in Adobe Photoshop for an exact scale.Īlso included are postscript files as well. The reason this will work with any existing Controller box that uses the parallel port to control the Clock and Signal lines is because we will release standard Firmware that will cover different pin configurations as needed.įind below the first picture of version 1.0Īs you can see, this is not going to cost you a lot of money to make!!!!!!!!!Ĭlick here to download the Hi Resolution images: usb-par-hi-respcb600dpi.zip With this simple circuit and our Firmware you will be able to simply plug it into your existing Controller box and using our software, run your Gcode via the USB Port. To compliment our new FREE Beta USB Application (Shown Below) along with new Firmware, we are going to release a very simple circuit that people can build themselves that will let you control any parallel port stepper motor controller via USB.
You just build it, use it and let us know of any improvements we can make. We supply the PCB design FREE, the Firmware FREE and the Windows Application FREE
Well now you can convert it to USB with this very simple Circuit below. Do you drive your Motor Controller usually via the Printer Port?
