Under Windows, you have to use third-party tools. Under Linux, you can create or write such an image file using the standard tool dd. In the simplest case, the image is a file with a size of exactly 720 KB, and just contains the blocks of the disks in the natural order. from amazon, if you don't have any blank ones left.Ģ) How do I copy images of the floppy data from or to a physical floppy? You can still buy new blank DD 3.5" inch disks, e.g. Unless you tell me that this doesn't work for some reason, I'll assume it is not a problem. If it's 720 KB 3.5" inch floppy, there's a very high probability you can read and write it from a PC, either using an old internal floppy drive, or buying a new USB floppy drive. Let's try to sort out the several points of your question.ġ) How do I physically read and write the floppy disks used on the CNC machine? The image is only an example of one of the repeating units throughout the disk image. The master program I require is the NC-GCode master, 3280B3. If it is any help, the machine is a Hurco KM3 CNC milling machine, with a BX controller. The machine originally used small cassette tapes to load the master, this floppy drive interfaces with a ~1994 tape emulator board. In response to the questions in the comments: I would like to know if anyone knows what this repeating unit is (It does vary slightly, in a predictable way), and if there is a method to replicate it so I can take the image I have and try and build a new master floppy. When I byte-by-byte compare the image downloaded against a good floppy I have, the output is identical, except for a series of repeating units from the floppy image, as is shown in the below image. I can get an image that runs the machine, using a different method of loading, which I don't have. I have more than one type, and the one I use most frequently has died. I have a machine with a floppy drive, from which it loads its 'Master', basically it's OS, every-time the machine restarts.
