Our 80's vintage matsuura started losing counts when the 5v supply started
to lower.. don't remember how far down..
Maybe 4.7v?

This is where halcmd comes in really handy.. When linuxcnc is launched -
bring up a terminal and type
halcmd -kf
than you can do a
show pin hm2[tab] enter. This will show you all the pins.
or if there are parameters to set things
show param hm2[tab] enter
or you can bring up 'show hal
It doesn't say anywhere in the linuxcnc manual for classic ladder - but is
there a limit for the compare block to just 2 compares?
ie..
I had this in the compare
%IW0<%W0,&%IW0>0,<7
For the life of me the logic just wasn't working.
Finally I put it in 2 separate compares..
%IW0<%W0 in one..

This is why I don't like smart servo drives.. lol.. You don't know how
well the drive is following the path linuxcnc is commanding..
With steppers - at least they stall.. The fact that the servo drive isn't
tripping a following error makes me think they are not setup correctly.
It should
I have written some simple hal components that set the index and then wait
for the index to be seen before continuing.. (like shape turning/boring)
probably not the greatest code Seems to work though..
Code snippet (indexenable is hooked to index enable of encoder)
// only set index
I would certainly go back into testing mode if Rob merged the TP changes..
:) That is stuff you can setup and let run..

One thing to remember is that is a very basic acorn setup. (With their cut
down control software). Plus you need a decent performing computer to run
the software.. so that needs to be considered..
Acorn is a good solution especially if you are familiar with the control
software.

that be? ;)
This is a nice press fit. it turned out better than I thought it would.
Now I just can't screw up the rest of the machining... :)

I downloaded the debian iso (the big 64bit version) - picked cinnamon as
the desktop environment..
apt-get installed linuxcnc-uspace and was up and running within a few
minutes after copying my configs..
I see the future and it is looking awesome..

I agree..It is so easy isn't it? Just use a ESP32!
I tried to write a machine controller when I was in my 20's... This was
before I found turbocnc (which sucked) and linuxcnc. (emc1)
I also helped test the trajectory planner improvements made when Rob added
n-segment read-ahead. It

And 99% of the time the B variant (brushless) drives are able to run

AMC makes some big drives... Not too expensive. You need to know current
and voltage you need...
Having a decently high count encoder on the spindle - you don't need a
'servo' spindle.. You can do fancy stuff like...

work is done with the hal component.. But would we be that lucky?

We had gotten some 5000 line - 2 count encoders on ebay a while back.
It certainly helped.. Higher would be nicer.,.(for bigger diameter testing)

I have had good luck with the 4 but haven't updated it recently.. It
seems maybe to be on the edge graphics wise - I would think the 5 would be
perfect.. (if the latency is good)

They can't be on the same subnet.. ( I always set the jumpers on the mesa
card so the IP address is 10.10.10.10 as most home networks don't use
this.) The default IP is 192.168.1. xxx range which is a common home
router range..
