Hello Everyone,

I am planning to convert a BF20 Optimum Mill to CNC and want use rigid tapping.
I am currently redesigning the spindle. For rigid tapping, a encoder with A, B and Z pulse is needed, atleast that is what my reserch got me.
I would like to have the encoder directly on the spindleshaft, so no beld needs to be used.

So my question is, how many slots does this "encoder disc" need to have?
(1 slot would equal 2 pulses right? Rising edge and falling edge?)

And would it be possible and practical to use a ac motor with a vfd to do rigid tapping?

Any input is highly appreciated.

Thanks in advance!

"Python can find the path to the running code with the __file__ system variable."

I know it now.
It's even used right here:
github.com/LinuxCNC/linuxcnc/blob/1c72d4...cconf/pncconf.py#L33

"In both cases you probably need to use the Python path manipulation functions to assemble the required path."

stackoverflow.com help me with it. It is not problem for me.

Now I have enough information to implement my original plan.
Create new files in the linuxcnc/src/emc/usr_intf/pncconf folder and then copy them to the new LCNC configuration using pncconf.

However, @Aciera came up with a better idea.
He doesn't want to create new files in the linuxcnc/src/emc/usr_intf/pncconf folder.
He wants to use the original data from the configs/sim/gmoccapy folder.
The advantage is that there will be no unnecessary duplicate data in the source files.

The problem is that I don't know how to define this path cleanly: configs/sim/gmoccapy
This path is different for RIP installation and different for package installation.
github.com/LinuxCNC/linuxcnc/blob/40fe3e...rc/configure.ac#L702
github.com/LinuxCNC/linuxcnc/blob/40fe3e...rc/configure.ac#L724
I think this might solve my problem, but I don't know how.

Hello all, i tryed to start a new topic in "CNC Machines Lathes"

Sadly it dosent let me post :/

Is there a problem or is the problem in front of my pc?

 

I Found a problem
If use FACE process
next step after FACE , not include G64 P Q Line
maybe problem from Post Processor of fusion360 

now my post $Revision: 44166 e813d608ccd22fb0949f73fcdb773b434407b131 $

I put G64 with PQ in  adaptive clearing step3 now can solved no machine jerky
Problem not from linuxcnc , problem from Post .

Thank you

Hello, I have gotten Linuxcnc running in my RPi 5 with MESA and am now moving on to cutting chips the original build uses a 10" Raspberry pi touchscreen (this: Cool hood 10.1 RPi screen), but I can't get the touchscreen part working. In the meantime I realize that 10" is small and I'd love to use the Probe Basic interface which required Full HD (1920*1080).

​​​​QUestion is: what touchscreen in 12-15" size have been proven working with a RPi 5? 

I am interested in the Waveshare 13.3inch DSI LCD ( Waveshare ) as it seems to fit from compact dimensions and have drivers for bookworm. I see these are dependent on kernel though so I am now fearful it may not work with our RT kernels? 

Any experience or other recommendation? 

​​​​​​Thanks!

I think at the end making your own encoder is similar effort like mounting a small timing belt.
Unfortunately hollow shaft encoders are much more expensive than the required parts. (timing pulleys, small timing belt and cheap encoder)

Maybe I should try ordering a slotted disc from a PCB maker for 2USD? They do drilling and milling and it is a matter of sending them the correct pcb file.
 

Hi
Now I use Linuxcnc V.2.9.4

I have a problem when Post G-code from Fusion360
If I post 1 post 1 command (Adaptive clearing) it's No jerk
but When I post  3 command in Gcode  
1. Adaptive clearing (tool 16)  Not jerk
2. Face  (tool 15)  Not jerk
3. Adaptive clearing (tool 16) Jerking

Step 3 my machine will jerk  when entering a curve and Velocity move slow down to 10-30 % feed , And will back to 100% speed when back to linear move .

My post I use
G64
G64 with P
G64 with PQ
Same problem can't solved .


 


I try
Post Gcode only Step 3. Adaptive clearing  it's not have a problem can run full speed and machine not jerk 

How I can fix this problem ?

Thank you
Asis

never trired OpenOCD, but you can send me the error mesage of the openfpgaloader.

with openocd you should make sure that it is written to the flash and not just to the ram, otherwise everything will be gone again after a restart

You can see whether it has worked by the flashing LED

btw, the default ip is '192.168.10.194'

the w5500 module has a little power led on the bottom, there is no jumper to power on/off this module.


not realy shure what you mean with the mapping,

the bob pins are mapped 1:1, if you need P17 (relais) on the BOB, you can use 'LEFT:P17' in your config.

 

if your BOB is connected to the other connector on the right, then you need to use 'RIGHT:P17'

 
So for a standard 3 axis mill, is the below scheme for wiring somewhat right.  I have no idea how to make a config for a lathe Though!  The second image has a funny output as marked

Guten Morgen Peter, 

vielen Dank für deine Hilfe

beim booten erhalte ich folgende Meldung

(1 of 2) Job logrotate.service/start running (43s / no limit)
(2 of 2) Job ifupdown-pre.service/start running (45s / 3min)

Den von dir vorgeschlagenen Befehl habe ich ausgeführt einmal direkt nach dem booten ausgeführt. Sobald der Fehler nochmals auftritt werde ich auch diese Log Datei hochladen. 

Den Inhalt der Log kann ich leider nicht interpretieren. Auf was muss man achten? 
Am Ende sind die zuletzt aufgetretenen Operationen? 

Im "normalen" Betrieb habe ich folgende tmax Werte (Maschine läuft schon eine Weile)

cnc@cnc:~$ halcmd show param *.tmax

Ich habe noch eine neue SSD gekauft um eine unabhängige Neuinstallation durchführen zu können. Vielleicht liegt der Fehler auch irgendwo in einer der vielen Anpassungen?

I understand this is the process of installing qtpyvcp and the Basic probe. In my case, it all works. Probably, I did not correctly identify the problem! I also correctly installed qtdesigner5 with linuxcnc widgets. But the problem is that the folder with the installed (vcp template) is not correctly configured for further editing! That is, I want to try to make my own graphical interface. I tried to create a GUI through flex gui, which was created by John, and it is very cool and quite clear. But I also want to study and try to create my GUI through qtpyvcp, but I encountered the problem that I described above!
Or you can start creating your own GUI without this step: www.qtpyvcp.com/tutorials/basic_vcp/basic_vcp_01.html

Was thinking about this today.......Very interested

Hi Andy,

Output of dpkg --list | grep libgpiod
I did a quick load of hal_gpio, didn't run a config, but it loads ok.
spix works fine even with my cobbled together 7c81 clone

Linuxcnc complains about /usr/bin/kill not being there but it's under /bin/kill which might have to do with debian having /bin /sbin & /lib being links to /usr/bin /usr/sbin & /usr/lib/ and Devuan not taking that road.

I'm actually Devuan to make this post.

I've only made a RPi5 image ATM but would you like an RPi4 image made ?

I am liking the look of this board. Did you do this in easyeda?

Suggestion, add the rpi 40pin header. Aside from being able to add stuff rpi side, I find it valuable for debugging the MCU/FPGA side of the board using a regular rpi without having to keep removing a cm module and you can use it as a backup incase you damage the 100pin hirose connectors or theres another RPi/chip shortage

Thanks! I'll try!
