Yeah, it always a shame it is so hard to take the machine with you on your travels.
Yes, it is the pump which doest not run, when pressing 3SH1, which made me consider 3F1. It might take some time until I can verify it, but I will let you know, what turned out to be the problem. And thanks for your suggestions for the troubleshooting, I will take those as a starting point.

Hi, I am trying to change mess around with my machines .hal file so when an M6 tool change request is generated it runs and MDI command. Every time I run it though I get the error "Can't switch mode while mode is AUTO and interpreter is not IDLE"

The net change I am making in hal is fromto
The MDI command in the INI is
My testing ngc file is
I've tried to keep things as simple as possible, but no matter what I try I keep getting this error. Could someone point me towards a solution?

Tommylight thanks for this, I had completely forgotten that the 7i96s has an output of 0-10v cw or ccw, it depends on how the motor phases are connected mechanically... on the lathe that I plan to retrofit, the main spindle is an Ac servo and the factory of course has cw ccw.. my question is whether in that case I will be able to set the counter direction with some magic in the hal
i mean m3-M4 ,or via some relay that would change the motor phases or a third option to find the input pin for changing the direction on the Simodrive itself? there is another option to take the analog output from the 7i77 because I planned it for x and z control. In the case that PhilipMe has, I have the same servo driver on my diy lathe and it can work in both modes, position and velocity also and torque over 25 13 analog inputs on the driver. in the manual there is a possibility to change the direction...PhilipMe check which parameter is responsible for that, it was a long time ago and I forgot.

I did set this up by loading Debian & then adding linuxcnc as deb files but that is the version as listed....
LINUXCNC - 2.9.2-168-ge7cd5217d9

And attached is a pic of the pause buttons.
qtdragon.external-pause

I am happy to format the computer & setup again from scratch if that is going to give me an answer.

If you can give me a recommendation I'm happy to try.

Thanks
Alex

You say you are using 2.9.2 but Qtdragon in 2.9 does not have an external-pause HAL pin.
Is your Qtdragon modified or are you actually using master branch (sometimes call 2.10)

It makes a lot more sense, now it uses the encoder values from the drive, your the greatest , thank you so much. I was looking for the pulse of reference and the sign of reference all this while

IMO, make it 2 boards. breakout board, and the core board

I wish we had an updated breakout board standard, like the generic db25 5 axis cnc board, but updated. then instead of having everyone remake the same thing but slightly different, we can just make core boards, and there would be a larger pool of users using the breakout board across other linuxcnc platforms , and we could all benefit from the economy of scale
 

I think this could be a good idea. Can we try and put together a list of what the core board should have? What connector or style of board should it be? I assume it should have at least:
Connector to a base board, what style? SO-DIMM like CM3+ and many other SOMs? I would say something relatively high pitch to make it small.
Power stage, what kind of input voltage range or we settle for 24VDC? OVP? Wrong polarity protection?
All decoupling caps,
Flash
Clock
Some leds for power and debug
...
As the FPGA will already be in a BGA package, I would not worry about example the connector being "solderable" as the board will already need a hot air station to be assembled but most likely its easier to let a fab house assemble it.

if i say 'already have all the components', i mean, i already used it or tested it,
and i think it is save to use it again

in the end i would like to have it so that you can have it completely manufactured by jlcpcb.
so it is completely independent of what parts I have
 

Sorry I misunderstood this completely. Could you list all the parts you would like to use for the "bare" fpga part?

Typically you would use 3 pins for Modbus: RX, TX, and TXEN

Dear folks,

I have a mesa 7i96s and want to set up 5 encoders and a pktUART Modbus connection.

So following talla83 youtube videos I got myself the efinity toolchain and started my experiments:

Adding the additional encoder input was straight forward except that my encoders are differential and additional encoder input on the mesa card take an a b signal so I had to get optical isolated rs485 to ttl boards

Now the pktUART part bugs me -- .as I want to use the smart serial as well.

so the first question: Is it possible to use two pins of the expansion port for Modbus communication?

the modified bitfile compiles (or whatever it is called) flashing is OK reloading is OK a mesaflash --read shows the pins (sry I can not attach it at the moment as I'm not in the shop at the moment) the modbus component description loads and at debug level 3 try's to send and receive but  nothing is happening on the assigned pins.

While you might be able to turn that drag-knife machine into a router, I think you will get better results for less money (time is money) by simply starting out with a used machine that is already a cnc router. Used machines can be surprisingly affordable. And you may not even need to do a retrofit, but if you do starting out with all the important pieces of the puzzle in place is a bit help.

The analog input is VREF and AGND (pin 25 and 13)

So it can run as a stepper motor and as a analog/spindle

I will make a wire diagram and post a new thread within 2 to 3 weeks (time permits) before powering.

Many thanks 

Philip

The analog input is VREF and AGND (pin 25 and 13)

That's the file. Don't trust too much in it.
Please backup the original one and place the new one (uncompressed) in its place.

Edit: I see right now that the result of calculations are wrong.
They give a huge number maybe because the decimal point "." or "," in the locale.
Please insert numbers directly without any calculation.

I am glad I finaly got the manual in the attachment

I dont see analog input to the controler
