OK, lets look at it from the other side, is that wheel with round holes on your actual machine?
where so sensor wires go and how many pins are there?

Any AI client I have tried just lies, particulalry with linuxcnc.
Don't get me started about the stupid question I got from a customer over the weekend about a product of mine. The question has never been asked in 16 years the product has been out there and was totlally irrelevant.

The exception seems to be Elon Musk's Grok. Perhaps the lies are just harder to pick

I dont think it did a single halpin correctly in the file, maybe the arduino one but im not sure.

How do I modify the files to make it run, or where can I get the specific information?


You should start by not using the entire thing. The thing you generated is essentially a broken version of the default/premade configurations we provide for remora The only thing it actually did was assign signals to the remora IO to add the buttons. The encoder signals arent connected to anything, and many of the parameters in the INI file arent real or connected to anything either, its mixing between joint C and Y, the speeds look insane and most of the ini entries are completely made up

Based on what I assume is the intended halfile, you have barely changed anything from the default remora halfile to begin with.


Compare that file to this one, known good and working
github.com/cakeslob/RRW_LAB/blob/main/Li...olset/remora-xyz.hal

it looks like i didnt upload my lathe config, but ill post that if you promise not to use that ai file

8gb will be fine. 
Linuxcnc runs happilly in 4 gb on most platforms.

I'm unsure that Sensor I was holding is not the original for this machine. i was hoping someone had the same machine and would be able to point me in the right direction. I guess I need a dual one. it should have 4 wires 2 on each side.

Not sure, your pictures show a normal single led/sensor device, but the schematics show a dual led/sensor device.
How many wires does yours have on each side?

The code needs a digital input pin for stopped-spindle to work
because i do not have this stopped-spindle digital input how can check
in subroutine code if spindle is stopped ?

mesa_input_pin can be hm2_7i80.0.gpio.003.in

whole halfile is wrong. its trying to mix other linuxcnc stepgen with remora

from ai
# Verbinden von Stepgen (Benutzermodus) mit den Achsen
setp stepgen.0.scale [JOINT_0]SCALE
setp stepgen.0.maxaccel [JOINT_0]STEPGEN_MAXACCEL
setp stepgen.0.position-scale [JOINT_0]SCALE

# Joins zu den richtigen Positionen und Feedbacks verbinden
net j0pos-cmd joint.0.motor-pos-cmd => stepgen.0.position-cmd
net j0pos-fb stepgen.0.position-fb => joint.0.motor-pos-fb
net j0enable joint.0.amp-enable-out => stepgen.0.enable

# Stepgen und remora zu den Echtzeit-Threads hinzufügen
addf stepgen.0.update servo-thread
# Den Remora-Modul initialisieren
setp remora.joint.0.pos-cmd 0

# Achsenzuweisung
net x-pos-cmd axis.x.motor-pos-cmd => remora.stepgen.00.position-cmd
net x-pos-fb  remora.stepgen.00.position-fb => axis.x.motor-pos-fb
net x-enable  axis.x.amp-enable-out => remora.stepgen.00.enable


from a remora example
# load the Remora real-time component
	loadrt remora-eth-3.0 PRU_base_freq=500000

# joint 0 setup (X axis)
	setp remora.joint.0.scale 		[JOINT_0]SCALE
	setp remora.joint.0.maxaccel 	[JOINT_0]STEPGEN_MAXACCEL
	net j0pos-cmd 		joint.0.motor-pos-cmd 	=> remora.joint.0.pos-cmd
	net j0pos-fb 		remora.joint.0.pos-fb 	=> joint.0.motor-pos-fb
	net j0enable 		joint.0.amp-enable-out 	=> remora.joint.0.enable


same with the inputs, its mashing up the other linuxcnc inputs with remora inputs

from AI
net lid-switch   <= remora.input.16.in
net start-btn    <= remora.input.17.in

remora code
net X-home 	remora.input.00

spindle with encoder

For rigid tapping i need only index signal from spindle shaft
A-B signals can come from elsewhere the encoder is mounted that is not 1:1 ratio correct ?

Old photocopiers have plenty of those, if you can scour one, and some bigger printers.

After homing X and Y, can I auto move to a non 0,0 location?

Category: General LinuxCNC Questions

Thank you very much. Homing works just the way I want it now.

I agree completely about naming -- it's very important. I didn't realize HOME_OFFSET was an absolute location until I got this working -- the word "offset" implies "delta" to me, not "location".  

As for the sign of HOME_SEARCH_VEL and HOME_LATCH_VEL, I've decided to try them with different signs, to eliminate the backoff step, as you suggest.  There may be (probably is) a difference between where the switch closes and where it opens, but for my mill I'm sure it won't matter, for homing purposes.

My final X config is this.  Y is identical, except HOME is 0, not 6, to keep the bed at maximum extension toward me.
MIN_LIMIT = -0.001
MAX_LIMIT = 12.0
HOME_IS_SHARED = 1
HOME = 6 
HOME_OFFSET = 12.1
HOME_SEARCH_VEL = .2
HOME_LATCH_VEL = -0.015
HOME_FINAL_VEL = 0  
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 2

Hello gentlemen !

Im a Newby and want to run a CNC-mill with a Mesa 7i76E and a Rpi 5.
I have  read the thread and think a RPI 5  with 8 GB will be  the right choice for
bookworm and the mesa. The 16 GB RPI5  won't work or is there any kind of news ?
The freason for the question is that i have to buy a RPI but which one is the best opinion and why ?
Can you help me ?

Thanks   a lot

Hey,

da ich nicht so oft mit dem Linux Rechner arbeite fällt mir so etwas nicht immer sofort auf.Allerdings habe ich den Eindruck, dass auf dem Rechner einiges nicht mehr stimmt, da auch der Firefox auf einmal in Englisch ist. und ich ihn nicht umgestellt bekommen habe, ohne ihn zu deinstallieren und neu zu installieren. jedoch funktioniert das System im Moment und ich hoffe, dass das auch so bleibt, ich habe keine Lust schon wieder das System neu aufzusetzen, da das echt viel Arbeit für mich ist, da ich nicht weiß, was ich wie machen soll.

Issue with inconsistent spindle RPM readings on Mesa 7i76e + LinuxCNC setup

Category: General LinuxCNC Questions

It could be a wiring/noise issue but typically this is because of the relatively
instantaneous velocity estimation (typically updated every ms), which tends
to accentuate the encoder inaccuracies. This fast update is important if a feedback
loop is used but a nuisance for a human readable display.

The way this is typically fixed is by low pass filtering the encoder velocity signal
before displaying it. If this has already been done, you might increase the time
constant of the filter
