Didn't get a chance to update and try the label yet as I'm working on the hal file at the moment. Couple of things I'm noticing now that I'm running some sims......

Since I added a qss, INPUT = TOUCH seems to not have an effect anymore. Pretty sure I had the touch style file browser before the qss but now it is back to the normal one.

The file browser is a little hard to navigate because it doesn't show the current directory, easy to get lost. Any chance you can add current directory at the top or something?

The flood and mist push buttons disable when a program is running. I'm used to Gmoccapy where you can still operate the mist and flood while running a program. Sometimes I forget to add coolant to the program and need to turn it on when it's running. Not quite sure why yet but as soon as the GUI disables coolant even if I stop the program I can't control it again with the hal buttons until I first turn it on with the GUI buttons.

I tried every possible combination with the X axis limits and homing. Still isn't working. I noticed something with the Z axis. The search velocity for home is a positive number. It should be negative? But I change it it goes the wrong way. My limits for Z are 250 positive away from the spindle. And 40 negative pass homing.Iv attached two other working ini files from other people. Iv noticed in one of them that for X axis the search velocity is positive. That would bring it up but the home switch is in the negative direction. Is there other settings somewhere else in a file for machine setup ?

Ok. As long as I am aware of it I can handle with it and I will choose smaller values.

Right now I am trying to get a 4 axis Machine running. Right now the scurve tp is making a lot dump things.

Grotius, do you have a 4 axis sim machine running to play with?

Boot into Ubuntu, mount the linuxcnc partition and bingo you have access to the files.

But if you can’t do that what’s more annoying, copying the files or not being happy with your machine ?

If you want to be helped you need to provide the info.

Without the info it’s hard to impossible for those helping and you don’t get the answers you require.

Yes, the problem with using a fixed blend radius on all segment intersections would be that the path deviation depended on the angle at which the two segments intersect, which would be rather unfortunate (If that is indeed what it is doing). For angles larger than 60° the blend radius and thus the feed rate could actually be larger for a 0.1mm deviation while angles below 60° would require a smaller blend radius to stay within a maximum deviation of 0.1mm.

Hi Cakeslob! Thank you for your reply. I attached some picture of my mill for clarity. So I got 1710 RPM motor with a fixed 1.8:1 pulley ratio, the encoder is on top of the second pulley, after that I have a lever for High/Low lever that with a 8.3:1 ratio. It's possible to put the encoder after all that but a lot of work. So my ultimate goal is when I call M3 S1650 the control output what he think is the correct 0-10v voltage, read the value from the single pulse Hall sensor and adjust the voltage to hit the target perfectly. I think it's closed loop. The cherry on top would be the ability of rigid tapping but not sure if it is possible with my current configuration. Probably a lot of work and if I need another kind of encoder i'm willing to replace it, i started this project 5 years ago and i'm not in a hurry. If I understand correctly, the remora PRUencoder doesn't work with single pulse hall sensor so your code is probably not suitable for my setup. The maximum pulse frequency is 5000/minute, does the EC-500 can handle that?

It would be enough, how did i wrote above.
Needed pins, photo/video of the mechanism and the sensors, schematic of the electric connection, example *.hal (with comments) for all cases.

I really like the philosophy and progress of this project!
I've never used PyQt6 so forgive my ignorance, would it be possible to map these controls on top of an image? Ive always wanted to render up an interesting backdrop in cad and add controls on top.

I'm trying to do some initial tests on my DIY lathe and having an issue with G33.1.

LCNC 2.10, Axis GUI

Specifically, I was trying to verify JoCo's concern that feed-hold and motion.feed-inhibit were disabled during spindle synchronized moves.

Attempted a simple rigid tap via MDI, and the Z-axis did the following unexpected things:

• Start position G54 Z0.1 (G53 Z-0.9)
• G90, G54
• S200 $0
• M3 $0
• G33.1 Z-0.5 K0.02 $0
• Z-axis waited for index signal
• Rapid Z- towards the chuck to Z-0.65 (not synchronized)
• Reversed spindle
• Moved Z+ at the programmed pitch to the starting point

I have no tool offsets set, and no tool/tap installed.

Why the heck did it rapid down in Z at the start?
Is this something to do with using caxis.comp?

The following was in the terminal if it helps:

EDIT - 
I wonder if my encoder sign is wrong...
forum.linuxcnc.org/24-hal-components/465...encoder-setup#248571

[
auto eth0
iface eth0 inet static

if you ping  192.168.1.121, you are pinging the PC

I would not use the 192.xxx.xxx.xxx range, but rather set the 7I96s
to 10.10.10.10 = W4 down W5 up +power cycle and set the host address
to 10.10.10.100:

auto eth0

Thank you for your answer.
I now understand every parameter and tested a little.

One thing I don't like. A given gcode with G64 P0.1 (mm) with an 90 degree edge. The small line upwards is 0.1 mm right of the edge. Your scurve tp sets a radius of 0.1 mm and the default tp sets a radius so that the distance between the blended path and the original path is not greater then 0.1 mm. I always set with a P value the maximum allowed deviation of a given path. So now I am not really sure. Can I just calculate something? 




 

Ah, that's not ideal. P needs to be a tolerance, definitely not a radius cause you end up up needing to pick a super tiny radius which entirely negated the point of G64.

Hi,

I have just received my Mesa 7i96s today from Mr. Andrew Beck of BECK CNC.

I left W4 and W5 at their default setting ( I can't see jumpers ) And I have followed the instructions given in this thread, and I am able to ping it.

This is what I have done:

With the Ethernet cable connected between Mesa 7i96s and Raspberry Pi4

[
behai@picnc:~ $ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether d8:3a:dd:25:8c:37 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
    link/ether d8:3a:dd:25:8c:38 brd ff:ff:ff:ff:ff:ff
]

I notice that eth0 shows <BROADCAST,MULTICAST,UP,LOWER_UP>

With the Ethernet cable disconnected:

[
behai@picnc:~ $ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether d8:3a:dd:25:8c:37 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
    link/ether d8:3a:dd:25:8c:38 brd ff:ff:ff:ff:ff:ff
]

I notice that eth0 shows <NO-CARRIER,BROADCAST,MULTICAST,UP>

So I guess my hardwired ethernet is eth0.

Then I log into my home router to verify that 192.168.1/24 is not in used as per the official manual instruction.

I then added the following lines into /etc/network/interfaces:

[
auto eth0
iface eth0 inet static
address 192.168.1.121
hardware-irq-coalesce-rx-usecs 0
]

Then I ran sudo ifdown -a followed by sudo ifup -a, both ran successfully. I.e. they produced no output.

Then finally: ping 192.168.1.121

The response is continuous until I pressed Control + C to interrupt.

I HAVE A QUESTION, PLEASE:

While the pinging was running, I disconnected the Ethernet cable, I expect the response to stop or at least to halt, but it did not. It continues to produce pinging notifications. Is this normal, please?

Thank you and best regards,

...behai.




 

vp, what are you trying to do and what is happening so far?

you just want a closed loop spindle? are you trying to thread or something else? is it only the z channel? most spindles are left open loop but with spindle feedback for rpm

The spindle run but doesn't look closed loop since the rpm is not right but I can vary the speed with the override.

lets start with this. what is the spindle speed? estimation/best guess,

this will get a little tricky because you have a pulley reduction and gear thing

edit, vp in my example, i am using an ABZ encoder to capture rpm and for threading, but its not a config for closed loop spindle
