There is a built-in behaviour which is almost correct, see LOCKING_INDEXER_JOINT, but it only works for the rotary axes (which should be an easy thing to change) and also only allows G0 moves, which is probably a bigger problem. This creates a "brake" pin for the axis which releases when the axis needs to move (and there is a handshake sequence, http://linuxcnc.org/docs/devel/html/man/man9/motion.9.html#JOINT%20unlock%20pins I think that we actually looked into this when This Old Tony popped up on the forum with a Maho that had a similar setup with a single motor for X, Y and Z.

I think that the motor "zero" angle for the 8i20 is defined as where
the motor sits with V+ connected to U and V- to V and W. If this is
where the index pulse is, then your encoder offset is zero.
You could do this with a bench PSU, but it's mayeb easier (and closer
to the real setup) to do it in a command-line hal session reset the
encoder to the index, then setp the angle to zero and setp the current
to a couple of amps (or enough to move the rotor) in each direction
and the encoder offset is the midpoint. (it's in counts)
Things are slightly complicated by the 8i20 built-in lead-angle
calculation. (ie, you give it _rotor_ angle and it calculates _phase_
angle)
eg:
halrun
loadrt hostmot2
loadrt hm2_eth board_ip=10.10.10.10
show pin
loadrt threads
addf hm2_read thread1
addf hm2.write thread1
start
loadusr halshow
{setup a watch of the encoder index-enable and counts)
setp encoder.0.index-enable 1
{rotate motor by hand until the index-enable resets)
setp hm2...8i20...current 0.5
{note the encoder counts}
setp hm28i20...current -0.5
{note the encoder counts)
{maybe repeat to get good statistics)
There may be enables to set, it's been a long time. You might need
more, or less, current. Depending on the pole count there will be
several zeros, one is likely to align very closely with the index.
If the encoder offset turns out to be zero, or close to zero, at this
point you should be able to scale the encoder to give a zero-to-one
output per _electrical_ revolution and connect the encoder angle to
the 8i20 commutation angle and spin the motor with current commands.

In both cases I use a single power supply shared by all the drives on the machine. The supplies are a simple rectifier and capacitor except that I also have resistors and relays for soft-start and capacitor discharge. Discharge is handled by a normally-closed relay that opens when the PSU power is turned on. Soft start on the lathe is handled by a HAL component, as the 8i20 returns bus voltage on smart-serial If the 8i20 bus voltage is above a few volts I do not allow the PSU to turn on. (to protect the relay contacts from welding) Then, when the PSU turns on it is powered through a power resistor to limit the surge. Then when the HAL component sees something close to full bus voltage it switches an output that closes a relay that bypasses the soft-start resistor. The mill PSU has a 555 timer for soft start, and I like this less than the HAL component as a solution, My system does not have any isolation between the DC power and mains, it is just a simple rectifier/cap. If you add a 3-phase transformer you will have much less input ripple and will also have some isolation. If I could find a suitable transformer cheaply I would use one. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

OK, so this time I have tested it, and it did take a bit of work to make it
work.
Here is the actual Python code that is working for me
#! /usr/bin/python3
import linuxcnc
import sys
s = linuxcnc.stat()
c = linuxcnc.command()
s.poll()
inifile = linuxcnc.ini(s.ini_filename)
print(inifile.find("EMC", "MACHINE"))
if inifile.find("EMC", "MACHINE") != "MyCOnfig":
c.error_msg("This G-code is for a different config")
c.abort()
It might not work if /usr/bin/python3 isn't your Python version. I wanted
to use "#! /usr/bin/env python" but that wasn't working on my particular
machine.
First make sure that just typing ./M100 in the nc files directory works. It
will error-out, but should at least try to execute.
When that is working, then start LinuxCNC from the command line:
linuxcnc &
(The & means that you can carry on typing commands in the command line)
When LinuxCNC is loaded and homed then you can try to run the M100 from
the command-line again
./M100
And this time it should work, or at least not error.
Then you can try running M100 from the command prompt, and that will work
if LinuxCNC can find the file.
If this all works, then you can finally try running the M100 from G-code.

How would you decide which config the G-code was for?
If you want to put an M-code in the G-code, and that is what determines
the target machine of the G-code, then maybe a custom M-code is the way, as
you suggest.
Something like M100 for one config, and M101 for the other.
file: M100
#! /usr/bin/env/ python
import linuxcnc
if inifile.find("EMC", "MACHINE") != "LinuxCNC-HAL-SIM-AXIS":
c = linuxcnc.command()
c.error_msg("This G-code is for a different config")
c.abort()
Make the file executable, put it in the nc_files directory, (or in the
SUBROUTINE_PATH) and it will abort running the G-code when it runs M100 if
the MACHINE entry in the active INI is not the specified string.
Probably. I haven't tested it :-)

LinuxCNC has the ability to run loaded files through a filter. This is generally used to modify the G-code, but there is no reason that it can't be a generic Python script that walks the user through checking the tools and measuring their lengths. If doing that you could have a fixture to hold the toolsetter near the operator station, and give them the opportunity to inspect the tools at the same time.

This is what I was suggesting (but didn't have the time to hack out the code, so thanks) It rather depends how perfect the spiral needs to be. The condition for tangency of two arcs is that their centre points are on a line perpendicular to the arc. If you play about in CAD you can get a feel for what this means for drawing a spiral out of 90 degree arcs. With LinuxCNC you could also try generating a bunch of X,Y points (in Excel for example) and using those to generate a spline.

If there is a rotary table, then if he wanted a 10 turn spiral at 6mm pitch: G1 F100 A3600 Z60 Should be all that is needed. Without a rotary table getting a true spiral is a bit more difficult as the radius of curvature continually changes, not something that G2 and G3 support.

Are you saying that you are using some tapped holes in the spindle face to hold Tee nuts to retain the tooling? Or are you maybe using the drive dog threaded holes? Whilst a proper repair to the drawbar seems like the correct fix, I think that a machined ring to retain an ER collet holder might be better than what I think you are describing.

I explain this all in my recent YouTube video, with an animation of how the generator works. https://youtu.be/YDxyNChCILU?si=1kMJ5d7FZ9qKFlAl -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Close, but no cigar, it seems. There is an equation in an online document (https://archiwum-bazakonkurencyjnosci.funduszeeuropejskie.gov.pl/file/download/587886) that isn't actually correct: x'= Dm/2×cosØ −2×e×cos(2Ø)+e×cos(4Ø) y'= Dm/2×sinØ -2×e×sin(2Ø)+e×sin(4Ø) However, after getting hold of a pirate copy of the standard, it turns out that it was only slightly wrong.

Ball screws have a maximum rpm rating, though I suspect you won't be getting near to that: https://www.steinmeyer.com/en/technology/speed-limits/maximum-speed/ I have seen both ends used to drive the Z screw. Rotary SMP's Schaublin (on Youtube) drives from the tailstock end. I think that the fixed end should be the headstock end, regardless of the drive end, so that the screw is in tension during conventional cuts. The wires are easier to route and protect if the motor is at the headstock end. But the drive sprocket might make it hard to get the screw as close to the bed as you would like. (much less of a problem with tailstock-end drive) Whatever you decide, plan on having extra unused screw length for some spiral spring screw covers. These were fairly expensive (and difficult for non-corporate entities to buy) when I converted my lathe, but have since become fairly easy to get hold of. (I think that I have even seen them on Amazon).

LinuxCNC 2.9.2 has been released. This is a bugfix release, with the most obvious change being that run-from-line in the Axis interface should now be working again. Packages have been prepared for: Buster - uspace - amd64 (PC) armhf (Pi) arm64 (Pi with 64-bit kernels) Buster - RTAI - amd64 Bullseye - uspace - ams64 (only) Bookworm - uspace - amd64, arm64 Bookworm - RTAI - amd64 For existing users of 2.9.1 on the above platforms this should be offered as an automatic update. If anyone badly needs Bullseye debs for RTAI or arm64 / armhf then let me know.

Halui is a program that replicates many of the actions that are otherwise handled in the GUI. http://linuxcnc.org/docs/stable/html/man/man1/halui.1.html In this case you would need to connect up the HAL pin halui.machine.on Does your machine start up in the e-stop active or e-stop inactive state? (This will depend on the wiring of the HAL e-stop loop) If it does then you will also have to toggle the halui.estop.reset pin. (And, having just checked, you can set them both at the same time, it needs to be estop.reset then machine.on) If the machine starts up in e-stop OFF then you probably just need a single line in a postgui halfile setp halui.machine.on 1 If you also need to reset the e-stop then it's a little more involved. So, one way would be to set up a couple of cascaded one-shots in HAL, then trigger them on the postgui halfile. In the main (or custom) HAL: loadrt oneshot names=estop-pulse,machine-on-pulse addf estop-pulse servo-thread addf machine-on-pulse setp estop-pulse.rising 1 setp estop-pulse.falling 0 setp estop-pulse.width 1 setp machine-on-pulse.rising 0 setp machine-on-pulse.falling 1 setp machine-on-pulse.width 1 net e-reset estop-pulse.out => halui.estop.reset => machine-on-pulse.trigger net on-signal machine-on-pulse.out => halui.machine.on Then in the postgui HAL: setp estop-pulse.trigger 1 The idea is that the postgui HAL first triggers a 1-second pulse to estop-reset, then the falling edge of that pulse triggers the machine-on. It would also be possible to trigger machine-on directly from the falling-edge of halui.estop.is-activated, but that would override the normal ui functions (the machine would _always_ turn on when the e-stop was released) and you might not want that. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

The 7i96S is available (unlike the 7i76E, which would be another good choice) but it is a little short of IO, having one input fewer than you require.

Rather than stepping through the code, you could try following the flow id information in the code from the G-code interpreter into the motion module with the help of an IDE. A good starting point is src/emc/rs274ngc/interp_convert.cc And the information here is only partly wrong: https://linuxcnc.org/docs/stable/html/code/code-notes.html -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

My mill has a 2kw 24V supply and then 4x buck converters (with LED voltage displays) to feed the PC motherboard, 5V and 12V logic. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

A meat slicer blade might work, but I would be concerned that they are not rated for the speed.

If it is Aa64 then the Fanuc hostmot2 component ought to work. https://linuxcnc.org/docs/stable/html/man/man9/hostmot2.9.html#Fanuc%20encoder (Others might too) The voltage and current are inside the range of the 8i20. The 8i20 needs to be externally commutated (In HAL) using the "bldc" hal component using the encoder feedback. I have been using 8i20s in my mill and lathe for several years with few problems. The STMBL drive has a Fanuc encoder component: https://github.com/rene-dev/stmbl/blob/master/src/comps/encf.c and would probably be a very good choice, if you can find any. They aren't really available at the moment without making them yourself and sourcing discontinued parts. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
