 I did as you said but i get an error of unknown m code

Possible causes:
- USER_M_PATH is incorrect (this is supposed to point to the directory that contains your 'M199' file not to the file itself )
- File name is incorrect (Do not add an extension eg .py)
- The file is not marked as executable

 do i need to add REMAP = M199 python = M199(the name of the script)

No, this is not a remap, it's a custom mcode (which lets you use any executable script)

do i need to add REMAP = M199 python = M199(the name of the script)

I did as you said but i get an error of unknown m code

"High current outputs 0 through 3 use full floating MOSFET switches ( a DC Solid State Relay or SSR ) and can be used just like a switch or relay contact. Maximum voltage is 36 VDC and maximum load current is 2A. Inductive loads must have a flyback diode. The output polarity of outputs 0 through 3 must be observed (reversed outputs will be stuck-on)."

I intend to use a 12v common power supply for both the output supply voltage and the DC motor. I hope that isnt a problem or should I have separate power supply for both? 

Also I think a DC motor is inductive. Do I need to use a 4001 diode to the DC motor?

That solves my doubt. Thanks everyone. I will see if I have any problems with the setup. 

Hi all.

Im new on here.Im struggeling with spindel start up when linuxcnc program startup.

M5 start the spindel.
M3 and M4 turn it off.

Spindel enable seem to have been reversed.Using a 6i25 card with a no name china model bob. I got for free.

So can I make it work or should i buy a different card.
Like a daugther card from mesa.





 

I have no experience with RTAI but the wiki page, like most things on the wiki, is likely outdated. I would try the install instructions on the github repo:

github.com/NTULINUX/RTAI/blob/master/README.INSTALL

- hy_vfd component has an option for debug mode, which may help:
linuxcnc.org/docs/html/man/man1/hy_vfd.1.html
- make sure you have the vfd set up to accept serial communications (see doc above)
- it's important to share the _exact_ error message you get, otherwise it's just simply impossible to even try to find out where it is comming from.

- gantry component is obsolete in versions 2.8 and later
- please post your hal and ini files.

at the moment, INT/RST is not used, maybe in the future.

> tooltip on the GUI:
it depends on where exactly you want the tooltip

Parallel port +bob. Mesa was too expensive for me for a proof of concept.

I found the gantry command (if it's called that) in the linuxcnc documentation, and thought that it might solve the problem.

Thing is: the problem stands with or without loadrt gantry. All the axis home, but only one of the ys moves while jogging.

wiki.linuxcnc.org/cgi-bin/wiki.pl?Building_RTAI_5.2_Packages
this is the wiki I am using to install RTAI and i am getting stuck on the "2.) Patch kernel with IPIPE, in this case we use 4.14.148". Specifically the 

$ sudo cp -aLv /path/to/this/RTAI-git-tree/ksrc/patches/v4.14.148/*.patch /usr/src/

(I am doing this in root)is giving me

cp: cannot stat 'path/to/this/RTAI-git-tree/ksrc/patches/v4.14.148/*.patch': No such file or directory

Im not new to linux, but definitely don't know enough about linux commands.

The out pins are small SSR outputs so need a supply voltage, say

+5V --> OUT0+
OUT0- --> POWER SSR IN+
POWER SSR IN- --> 5V GND

There is a relay called KA0 (CNC ON/OFF) with two bottons on the panel. This cut off the power form the windows XP computer.
On this computer is the whole cnc with a pci card.
Actually this is your main power ON/OFF so it does what's design to do kill power to the whole system.

The machine also have two safty switches... the goes to the relay KC0.. but the relais goes to an input off the cnc-controller.
It is not hard wired to something else.

This part requires a revision.  I like to be able to cut power to any motive power that can cause harm (spindle motor/drive servos). so usually when an external estop or software estop or manual change tool is issued, the machine should go through hardwired estop circuit and should not resume operation until the estop is pulled than a hardwired rest button is pressed by the operator. The next best thing is to use an external safety relay.

I have also a main- relay that cut off the power form the servos. But this relay is switched by the cnc-controller... not hard.

That will be solved in the previous part.

For the touchscreen you will need to experiment.
For the hand wheel control it should no be a problem you might need to purchase an extra card for more io's  such as The 7I84 which is a remote isolated 32 input and 16 output digital I/O card. and allows up to two mpg wheels.
