![]() Surprisingly, the 2-pass looks worse than I thought. Offset looks the best IMO, but it does have this obnoxious "X". (6) Climb-only raster (using Cross-grain orientation). (5) 2-pass raster: With-grain raster, followed by cross-grain raster (4) Climb-only raster (using With-grain orientation). (bad circumstances: 0.25mm TBN, 40% step-over rate. I did a test run, with deliberately bad circumstances, to emphasize the effects. The end result is very similar to my original plan, which was to take a raster, reverse every other line, and start from the middle outwards. I simply do (an over-extended) rectangular offset toolpath, then I clip the parts that I don't want, using this tool. Though I didn't yet write the script that I promised, I did find a way to create a climb-only raster toolpath, using existing tools. Hello friends! Hope you're having a lovely weekend ![]() Forget about a hard drive, at the time, a 10Mb hard drive was north of $10K. Yup, the first programming system I used had a Data General 8Kb RAM computer, and 8 inch floppy disks. But back in the day of 8Kb and 16Kb RAM computers, files had to be used. These days a file is generally not used, just memory. So, internally, there are two "processing" passes to create a gcode file. Then that file is "post" processed into machine specific g code. So I am not the one making these terms up.įrankly, I always thought it should be called post-post processing.Įdit, a little more info on these terms: It was called post processing because the computer software prepares what is commonly known as a "CL" (cutter location) file that is not machine specific. For a frame of reference, way back in the day I worked for MDSI, Numridex and Encode. But that is what it has been called for as far back as I can remember. I know, I know, it makes no logical sense whatsoever to call "pre". The term "pre processing" was/is used to describe modifications to a g-code file after post processing but before loading it into the machine control. This term has been used since the earliest days of NC/CNC dating back to at least 1974 when I first started with NC machines. ![]() The term "post processing" is not unique to Vectric products. ![]()
