No wonder what I was seeing was confusing, its also base 0, so when I 
tried gpio.021 i actually was hitting the Y connector, which I saw but 
didn't believe. Duh! Printed 3 copy's as theres now a 2nd bob on TLM's 
5i25 too.

Thanks a bunch Peter, as I have plans to fix up its power switching in a 
similar manner, but I don't have near as many u-f in its spindle motor 
psu, so it comes alive w/o any excitement in the sheds service box.

Greetings all;

I have added a 40 amp SSR in the relay box with the two that are
sequencing the spindle's psu startup for a soft start, but its not
intentionally connected to those 2  other than as a power src when
its enabled.  Except this one is to be enabled by the E-stop.out
signal when its on, f1 pushed once after start.  The idea is to turn
on motor power etc to the remainder of the system with the F1 key.

I have a std 5 axis bob on the 5i25's P2.

But I am not having any luck finding what would be gpio.020, aka the
5i25's p2 pin 3 at the bob that's plugged into p2 on the 5i25. I can
find 2 or 3 pins at ground when LCNC is started, and enabled, but
not on the x connector. All are logic 1 or 5 volts on a DVM then
LCNC is stopped.  So what would be the correct pin of a std bob to
hit the enable signal of what the what the bob thinks is x-enable?
If it was the 5i25 p3, it would be gpio.003.  But its not and I'm
lost, What I want to do is feed the bobs 5 volts to the + label of
the SSR, and send a logic 0 to the - terminal to enable the SSR.
But what I see in dmesg and in halconfig or halmeter, isn't match my
old thinker's conclusions. And it looks like I should be using an
in-not because e-stop-out is high when F1 is on and I need to
invert, only when LCNC is running.

Thanks all.

it, I want to cut some gears with it. But I didn't realize how heavy the

Maybe clean the residue with isopropanol BEFORE scouring the
surface---otherwise you could introduce oil into crevices that it'll
be hard to get out of.
Then sandpaper, and maybe one more isopropanol wipe for good measure.

Why not add a 4th axis configuration to each machine that might use it? Then 
you can properly integrate the motion control?



You can actually do it with a single config. I have a jumper in one of the 
connectors that the rotary connects through. If the system doesn?t see the link 
(via an IO pin) it doesn?t enable the axis.

Mine actually f-errors if you try to move the axis, but that would be easy to 
fix.

Perhaps I misread the original request but are the associated mills controlled

I do essentially the same thing w/o the detection jumper. If its 
unplugged it still has a missimg/undefined home_sequence so its marked 
as homed whereever it is. Like this in the ini file:
[JOINT_3]
TYPE= ANGULAR
HOME= 0.0
HOME_SEQUENCE   = 0
HOME_SEARCH_VEL = 0
HOME_LATCH_VEL  = 0
HOME_FINAL_VEL  = 0

It, if used, generally gets touched_off someplace just to establish a 
reference.

Just never unplug or plug it in with power applied.

To make that easier but its not done yet, I have just obtained some more 
40 amp SSR's, and will add an activator link in my .hal file so that all 
motor power is off and the machine unhomed when E-stop is false. I 
already soft-start the spindle supply with 2 more relays, driven by 
motion-enable, one to soft-start that supply thru a 100 ohm 200 watt 
resistor and another one to bypass the resistor 3 seconds later so I can 
service its 17 amp max load with a 20 amp breaker, else its unrush will 
reliably clear a 30 amp breaker. And a 30 is not code on a 10 ga circuit 
here...

I think maybe some of the machines he wants to use it on might not be running 
Linuxcnc.

Why not add a 4th axis configuration to each machine that might use it? Then 
you can properly integrate the motion control?

You can actually do it with a single config. I have a jumper in one of the 
connectors that the rotary connects through. If the system doesn’t see the link 
(via an IO pin) it doesn’t enable the axis.
Mine actually f-errors if you try to move the axis, but that would be easy to 
fix.

Whomever is downloading the 2.5 gig kernel image from 173.205.33.27 (GIT) 
in McLean VA, why?

There is an installable kernel there thats only 149 megs, called 
rt-kernel.tgz. Please get it instead and use it. It's exactly the same 
thing but just stripped down to what you need from that image. I've only 
a 300k upload speed.

[Emc-users] LCNC for raspbian-armhf on rpi4

[Gene Heskett]

The build of a fresh pull of todays master is trotting right along, so in 
an hour or so there s/b fresh downloads of master (2.9.0-pre) available 
on my site.  These run on raspian-10.3 armhf flavor. There is also a 149 
meg preempt-rt.tgz kernel. Still a 4.19.71-rt, but not a 2.5 gig dl.

Goto the link in the sig, add 'lathe-stf' to the address bar & hit 
return, find the linuxcnc4pi4b link in the listing, click and you should 
see the new stuff.

Since the rpi4 is running apache2, I may see if I can nat a different i/o 
port in my router to give folks direct access to the pi's build 
directory.  But that will also take a bit of apache2 configuration on 
the pi, so it probably won't happen today. If and when I get it working, 
I'll append it to my sig. In the meantime its available now at the old 
link in the paragraph above. And in runs fine on my rpi4b.  Have fun 
all.

Cheers, Gene Heskett
