Here are the general signals that was generated for me by pncconf some years ago.

net spindle-vel-cmd-rps-abs    <=  spindle.0.speed-out-rps-abs

net spindle-cw                 <=  spindle.0.forward
net spindle-ccw                <=  spindle.0.reverse
net spindle-brake              <=  spindle.0.brake
net spindle-revs               =>  spindle.0.revs
 net spindle-at-speed           =>  spindle.0.at-speed
setp spindle.0.at-speed 1
net spindle-vel-fb-rps         =>  spindle.0.speed-in
net spindle-index-enable      <=>  spindle.0.index-enable
net spindle-revs              <=   hm2_7i76e.0.encoder.04.position
net spindle-vel-fb-rps        <=   hm2_7i76e.0.encoder.04.velocity
net spindle-index-enable      <=>  hm2_7i76e.0.encoder.04.index-enable
net spindle-manual-cw     halui.spindle.0.forward
net spindle-manual-ccw    halui.spindle.0.reverse
net spindle-manual-stop   halui.spindle.0.stop
You would need at least the enable and one of the vel-cmds.
Maybe forward/reverse and so on.
They all connect to the spindle pins (created by the motmod component).
Speed feedback is optional but nice to have, at-speed if your spindle can do that.

I think you are suggesting that you could supply "fake" commutation signals from LinuxCNC to the drive, and that might be enough to persuade the drive to start working?

This is what I'm thinking. I will try it as soon as I have time and report back.

I think 6.1.0-30-rt should probably be OK. (though I think that the packages were built on 6.1.0.10-rt )

Hello,
you answered one of my posts. Can you help me installing the right kernel. I don´t know how to do it.

"Try repeating after typing
sudo apt purge raspi-firmware
If you still gets errors, share the output of uname -r as it appears it is trying to install an incorrect kernel version. "

I got this message 6.1.0-30-rt-amd64

So does this mean that the BLDC module doesn't output commutation before/during the startup indexing procedure? If commutation outputs are suppressed before index pulse is found I may have a problem. I was thinking that it could output them, even if they were off by a little, and hopefully it wouldn't jostle the motor around too much.

That might actually work.

If the motor has little enough load on it at startup to magnetically align so that the "fake" commutation becomes true, just long enough for the drive to see the encoder index, then start running off that, you might be able to get things working.

I suppose it's worth a try, it's an hour's work and 3 wires.

The question is whether the drives can do preset velocity with no commutation.

Hello,
this is my almost working postgui. This works is Input-04 is a switch. But i want to use a push button. What can i do?

#[Startknopf]
loadrt or2
addf or2.0 servo-thread

loadrt not #mit diesem Befehl wird ein not.in/out in die Pins geladen
addf not.0 servo-thread
net Start.not.out => not.0.out # hier wird not.0.out startbar gemacht

net Start.ext.an <= gladevcp.Start => or2.0.in0
net Start.ext.an1 <= hm2_7i76e.0.7i76.0.0.input-04 => or2.0.in1
net Start.or <= or2.0.out => hm2_7i76e.0.7i76.0.0.output-05 => halui.machine.on => not.0.in # Eingang not.0.in wird über den or2.0.out gesetzt

net Start.not.out => not.0.out => hm2_7i76e.0.7i76.0.0.output-06 => halui.machine.off
net MachineLED <= halui.machine.is-on => gladevcp.led_Startstopp

Tried something, but to much chinese ;-). I did some comments after #

addf or2.0 servo-thread

loadrt not
addf not.0 servo-thread
net Start.not.in => not.0.in #<= ???? must be hm2_7i76e.0.7i76.0.0.input-04
#net Start.not.out => not.0.out

net Start.ext.an <= gladevcp.Start => or2.0.in0
net Start.ext.an1 <= hm2_7i76e.0.7i76.0.0.input-04 => or2.0.in1
net Start.or <= or2.0.out => hm2_7i76e.0.7i76.0.0.output-05 => gladevcp.led_Startstopp => halui.machine.on

#net Start.or <= not.0.in => hm2_7i76e.0.7i76.0.0.output-06 => halui.machine.off
#net Start.ext.aus <= not.0.out => hm2_7i76e.0.7i76.0.0.output-06 => halui.machine.off ## almost work, but gladevcp.led_Startstopp doesn´t work

Hello,
i just try to complete the function in the attached file. My postgui.hal:

#net Start.ext.aus => gladevcp.Start-not => hm2_7i76e.0.7i76.0.0.output-06 => #halui.machine.off

I can´t get output-6 and halui.machine.off to work.
Please help

LinuxCNC must not have been running when you ran halcmd show all *.tmax
otherwise it should have show a set of parameters like:

Parameters:

    33  s32   RW              0  hm2_7i76e.0.read-request.tmax
    33  s32   RW        1159140  hm2_7i76e.0.read.tmax
    33  s32   RW         270636  hm2_7i76e.0.write.tmax
    23  s32   RW          45260  motion-command-handler.tmax
    23  s32   RW         942716  motion-controller.tmax
    27  s32   RW         233832  pid.0.do-pid-calcs.tmax
    27  s32   RW         246480  pid.1.do-pid-calcs.tmax
    27  s32   RW          21700  pid.2.do-pid-calcs.tmax
    27  s32   RW          20144  pid.3.do-pid-calcs.tmax
    24  s32   RW        1564056  servo-thread.tmax


and yes, RealTek Network interfaces have issue with real time when using the stock
Linux kernel driver, the suggested  fix is to install the DKMS 8168 driver.

This affects any Ethernet or EtherCAT connected device that use the standard RealTek in kernel driver.

ChatGPT (or any AI) is going to do very poorly with anything that hasn't been done before.

6th axis for ATC

Category: General LinuxCNC Questions

Hello, I use QtDragon with 5 axes (X, Y, Z, B, C) and have expanded and flashed my Mesa 7i76EU with a 7I85s. The additional 4 axes are also displayed with sudo mesaflash --device 7i76eu --addr 192.168.1.121 --readhmid. As far as I know, QtDragon can only handle 5 axes. I need an additional axis for the ATC that doesn't need to be displayed in QtDragon. Can I control it via G-code, e.g., G0 W100, or if G-code isn't possible, via HAL commands?

I read that you can customize the xyzbc-trt-kins file, but I can't find it?

WCS Problem with Linuxcnc/qtdragon

Category: General LinuxCNC Questions

I have avidcnc from 2017 from wich i recently replace the breakoutboard with a mesa7i76EU to make it work with linuxcnc.
Everything seems to be working fine,

The only problem i have is that it doesn't seem to use the WCS coordonates after i zero my machine But keeps using only the absolute coordinates when im running my gcode
This causes the machine(zaxis) to move into the bed when starting the program.

can somebody help me please.
Thanks in advance.i added my gcodeand my hall/ini files for qtdragon.
