Andrew - I prepare GCODE in my postprocessor - it takes 3d points from cad 3d program , and then traverses points of edges and outputs gcode.
OK, I made correction as Andrew proposes, but this transition from straight line to edge cutting results in velocity ripple (seen in halscope on video below) - is it possible to have more smooth transition? Any idea how to correct this if it is possible at all? https://youtu.be/71HJZ2YjnJU regards On Mon, Aug 22, 2016 at 12:35 PM, Klemen Živkovič <[email protected] > wrote: > Because machine has two rotating disk, that are used to clamp pipe. > If I want to have both disk to have same angle (so they can grip > rectangular pipe) I need the ability to separately rotate both of them. > I also use two separated stepper drivers for this reason. > For ilustration you can maybe check pictures of my project at: > https://goo.gl/photos/4A623DBE1DQRwYfcA > > regards, > > On Mon, Aug 22, 2016 at 10:40 AM, Andrew <[email protected]> wrote: > >> 2016-08-22 2:43 GMT+03:00 Klemen Živkovič <[email protected]>: >> >> > Oh yes I see how you calculate it for this example on simulation. >> > Actually I would need to make and calculate it for general case where >> > fillet can be only quarter of length or any other arbitrary length.
