I also am using LinuxCNC for industrial machines and one thing I would
like to add is that I do not see a point to go this route - developing
Your own cnc controller. You alr

i was starting to suspect that was the case. But no i didn't officially
know that.

Yes i have seen that video, i actually commented on it asking for the

I know you haven't heard much from me, but I have been using linuxcnc for
two years now, both industrial and hobby use. I have been taking for
granted those who have made and still make this a great free resource with
excellent support.
So this is my formal thank

LinuxCNC will allow to jog off the limit switch. It will stop the
motion at first and then there will be check box "Override limits" or
something similar. Check that and You can jo

If I may be forgiven for mentioning it, in VB the format would be something like
def __init__(self, halcomp, builder, useropts):
fb = builder.get_object('filechooserbutton1')
Andy,
I don't think there's much more you can do to make it neater. If you create
the filter object in your glade file you could get rid of the self.filt =
gtk.FileFilter() and self.fb.add_filter(self.filt) calls, but then you'd need a
builder.get_object('filter') before you'd be able to add y

I am not sure what you mean. "bldc" uses normal maths functions to
work out the sine values.
Are you asking about how the Hall-sensor table works?

Andy would you care to enlighten me a little on your sign lookup table? I
have an xmega laying around I have been playing with. I have it decoding
and picking up the hall positions. But I'm not grasping the sign lookup
table. I have read a half a dozen articles on it. In sure I will figure
out,
Excellent that is what I figured.
Thanks

No, bldc doesn't generate PWM, it generates amplitudes for a PWM
generator based on measured rotor p
Emc has pwmgen as a hal componant... Tecnically you could use the software
pwmgen componant to generate pwm. I have run a rather large brushed servo as
others have. Might be good for testing theories..

Hi
I'm planning to wire my limit and estop switches to a relay that will cut
power to the spindle, disable the stepper drivers and inform Linux CNC that
an estop has occured. I want do this this as otherwise there may be no way
to stop the machine if a software error occurs.
This means I will ne

No, it does not do actual pwm generation.
Mesa FPGA cards have 3-phase pwm generator module.

I don't know if I'm miss understanding the bldc Hal component. I have a 3
phase half bridge driver ic that uses cmos, or ttl as inputs. So I
configured bldc with q for encoder, h for halls, and B for 6 bit inverting,
and 6 for output signal. Is it supposed to generated sinus pwm signals on

I'm entertaining feedback on the principle; this is not a patch yet; it's still
shaky on abort and limit checking.
The nice thing is that it's fairly unintrusive - all through H
