Hi,
hier kannst du bei Autodesk ein Standard PP herunterladen, der bietet schon einmal ne gute Basis, mit diversen Zyklen die schon integriert sind.
Fusion-PP    (nach LinuxCNC Turning suchen)

pncconf Clearpath SDSK settings

Category: General LinuxCNC Questions

I have my new 7i96s and my machine is - almost - ready to be powered up. As I run pncconf, I am looking for a little handholding to make sure I get the entries right. I have four Teknic Clearpath SDSK CPM-SDSK-3411S-ELS, one on each axis, with a paired Y gantry, found here: teknic.com/model-info/CPM-SDSK-3411S-ELS/ . All are powered by an IPC-5 75v power supply. I have a second ps in case one isn't enough, but I think it is.

The maximum acceleration I calculated as 49800 mm/sec^2 is WORLDS away from the default 750, and pncconf doesn't allow more than 10000. That's just the tip of the iceberg! I can't be the first person to use Clearpath SDSK servos on a LinuxCNC machine; where can I find examples of settings someone else has already proven out?

Additionally, I think I have the wiring correct for HLFB, aka drive alarm, but I am still in pncconf and I don't even know how to assign the pins there. The only options that seemed like they would make any sense were "digital in 0", and so on. Does that sound right? If not, what should I use?

looks like you have the order of the read_all and write_all wrong.(lcec should be first and last) but not sure if that's what has broken it.

Resolution and speed with servo motor

Category: General LinuxCNC Questions

hello
base period = 100 000
servo period = 1 000 000


steplen = 1
step space = 0
scale is 10

my one rotation is 10mm

so that scale*1 rotation is 100 pulse
i need to make >500 pulses for one rotation

if i make 100 scale
the speed is going down and linuxcnc give me following 0 error(axis x following error)

QTDesigner PATH issue

Category: General LinuxCNC Questions

My guess is from these lines in pstat.py:
            # share directory moves when using RIP vrs installed
            home = os.environ.get('LINUXCNC_HOME', '/usr')
            if home is not None:
                self.SHAREDIR = os.path.join(home,"share", "qtvcp")

most every file uses SHAREDIR as a base.

If you open a terminal and type:
printenv LINUXCNC_HOME
does it return anything?

Somehow Qtvcp thinks that linuxcnc is installed rather then RIP.
