wow! you should be a good assembler programmer or something like that. I guest.
this looks more like logical gates procedures than a sequential programming language.
I still have difficults to understand the logic.
Well, when I have time I will take like a Qitz to lern it
Thanks

ok then I got final solution, just I change the way in the driver to let it receive more coherent values:
CW =3
CCW = 7
STOP Keeping enable = 1
and I made this change, Hope helpful for someone.

Works perfect !

Great ! Great ! Great ! Greaaaaaaaat !
now I should studi what you did !
but..M5 still dont works (not is your wrong) just I didnt ask help about and M5 the value to pass via modbus is 16 and not 0 (just 0 disable the servo shaft.
If you can modify the brain on time then will be great but BTW I will study now it.
Your Help value was really high for me. THANK YOU SO MUCH !
Where I can learn how works the logic of the brains? because I shaw some video tutorials...and also find docs on inet but failed and dont found them.
Thanks Again Alex, for  your prompt and perfect answer.

lo mas normal es que ese motor a nivel de hardware no este buen configurado. es decir,
si se calienta , va a trompicones o mete mucho ruido y no es un problema mecanico que este interrumpiendo el deslizamiento suave del eje entonces seguramente lo que ocurre es que el driver del motor de pasos no este configurado con una subdivision de pasos alta por ejemplo mas de 128, y lo mas probable tambien es que los amperios seleccionados en el driver no esten seleccionados justo con los amperios que necesita el motor en sus especificaciones.
Asi mismo, si la fuente de alimentacion DC que estamos utilizando no tiene la suficiente intensidad en amperios necesaria segun se haya seleccionado en el driver y las necesidades del motor, entonces seria tambien un problema.
Asi pues, lo primero de todo revisar que el hardware es el adecuado en esos tres elementos, que no hay ningun impedimento mecanico en el eje y que la configuracion que se haga en el driver sea correcta intentando dejar al maximo posible la subdivision en micropasos puesto que esto dara mas suavidad y menos resonancia al motor, con lo que se evitara ruido y calentamiento del mismo.
Si todo eso esta bien entonces luego mira en mach3.
Suerte

VB and the development of wizards / script writing records using modbus in external device

« on: November 16, 2013, 12:13:11 PM »

Hi everyone !
Because my adventure with brains is in conflict to understand the logic of the lobe I decide try this time with a macropump for my target but, Even Im VB programmer Im not familiar with the script for mach3 so I need a little help from a good gui that can drop some instructions here and open a light in my darkness.

What I want to do is, the funcions or sub callings needed to write 2 different register via modbus.
Attached the Modbus control config. Thats works perfect using the test button, I can write in address 0 any value just a number for example 100, and also I can write value (also number) in address 66 both are holding registers.
but I dont  know how translate t his manual operation to the sentences in VB script.
Thats all that I need and then the rest of scrit of course I will deal with it.
Can somebody help me?

Thank you !

Hi Everybody!
Attached the brain that let me crazy for several days!
Just I have a servo Spindle to control via Modbus . The connection via modbus is ok.
Happen that when the brain is enabled always send the last value (in this case 112 to the modbus and then the spindle always run in reverse.
if I delete the last rung then send the value to run in CW (48).
Means that dont care about the output signal led state.
If I view the brain execution then I can see with the intructions M3 and M4 turn green first led or second but...still send (I think the 2 Modbus orders first 48 and later send the 112)
Where Im wrong?
Thank you in advance
