Sorry, yes, I replaced the qtaxis.ui in my configuration folder/qtvcp/screens/qtaxis.ui (new), and then what must I do?.

Hi PCW,

Noted. Will look to the pncconf in depth next week. I tried the pncconf yesterday. I got to the point where you choose which mesa boards I am using. From gathering in the internet, i should be using the 5i25 since 6i25 is not in linuxcnc and 7i77 x 2 i guess...

As for the Analog I/O thank you for the clarification. So instead of ENAn+ and ENAn-, I should connect the servo drives to the 7i77's AOUTn and respective GND.

Thank you for your assistance.

If you already have the cards, then definitely stick with them, they will work fine.

You can expand to really rather a lot of IO by adding smart serial cards, if you need to.

You don't replace the original ui file, though that will work.
you put it in YOUR CONFIGURATION FOLDER/qtvcp/screens/qtaxis/qtaxis.ui
Qtvcp will see it there and use it instead of the original/

Normally the basic configuration is created by one of the two configuration utilities:
pncconf or MesaCT. These are GUI programs where you enter the intended interface hardware and
basic machine specifications (dimensions, encoder scaling etc) and I/O connections
(limit/home switches spindle controls etc)

Note that the analog out pins are AOUTn. The ENAn+ and ENAn- pins are a switch to enable the
drives (on when enabled)
 

Hi all 
I am unable to loop more than 25 times using the M98 and L commands. Eg the below code will execute 25 times even though L says 40 in the latest 2.9 version. Please help!

M98 P101 L40
M2

O101
some code

Hi Andy,

Good day. From what i have gathered in the user manuals available in the internet and checking the existing connection from the servo controllers to the non-functioning acramatic 2100 controller,

each servo controller (X, Y, Z, and Spindle) has
1) +-10V inputs (i assume to drive the servo motors)
2) An A & /A, B & /B, and Z & /Z encoder outputs.

I was thinking of connecting the +-10V servo inputs to the 7i77 by its TB5 outputs namely, ENA0+-, ENA1+-, ENA2+-, and ENA3+-.

Then connecting the servo encoder outputs to the 7i77 by its TB3-TB4 inputs namely, QA0 & /QA0, QB0 & /QB0, IDX0 & /IDX0, for all axes and the spindle.

If that is correct, my only problem now would be the configuration under linuxcnc which I have no idea where to begin.

As I have already purchased the Plug-N-Go Kit (7i77 + 6i25) from Mesa, I would like to use them. But will look into your suggestion since they have more pins. Also, it would be generally hard for me to purchase additional boards since I am from the Philippines.

Thank you very much for your assistance.

Thanks

What version of LinuxCNC?

I don't recall any encoder bugs of that type, is it possible
there is a 32 bit wrap (that's a lot of turns though unless you
have a very high res encoder)

Also could be some kind of failing hardware (PC memory, PCI, FPGA card etc)
