Hi, unfortunately the pluto-p board is the poor relation of interface boards in lcnc. But anyway I have fixed some bugs in the pluto-servo driver. Due to lack of stepping equipment I have not yet done for pluto-step. I've also made a pluto-servo-spi driver for raspi. If I could spent more time for hacking I could try to make a pluto-step-encoder version for you.
Cheers. <http://dict.tu-chemnitz.de/english-german/relation.html> On 2013-08-18 22:07, tuxcnc wrote: > Hi. > > There are available cheap stepper motors with encoders, for example > 86HS80-EC-1000. > And there are also a cheap cards Pluto-P. > Pluto-P has two modes, first PWM and encoders and second stepgen ie > STEP/DIR > There are two firmwares, one for servos, one for the stepper motors. > It is not possible to use encoders simultaneously with the stepper motors. > There are stepper drivers with a closed loop, but they are expensive and > only work on one axis. > It would be better to move the loop to LinuxCNC, then, when one axis > stops or slows down , the others axis can operated synchronously, slows > and waits for the slow axis will move. > > And now the question: > > For the Pluto-P are available sources of firmware and modules for LinuxCNC. > In directory src/hal/drivers. > Could someone find the relevant parts and write firmware and module for > the Pluto-P, supporting both encoders and stepgen? > In my opinion, in stepgen and PWM are the same number of pins, so may > be, it just should be replaced code of PWM by the code of stepgen, in > servo program. > But I don't know this device and its programing language. > > Regards. > > ------------------------------------------------------------------------------ > Get 100% visibility into Java/.NET code with AppDynamics Lite! > It's a free troubleshooting tool designed for production. > Get down to code-level detail for bottlenecks, with <2% overhead. > Download for free and get started troubleshooting in minutes. > http://pubads.g.doubleclick.net/gampad/clk?id=48897031&iu=/4140/ostg.clktrk > _______________________________________________ > Emc-developers mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-developers -- "In der Wissenschaft siegt nie eine neue Theorie, nur ihre Gegner sterben nach und nach" Max Planck ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
