PoKeys / About Pull up resistor on pins 32...40 and 46,47,50,51 and 52

« on: April 16, 2012, 05:00:03 PM »

Hello

In page 4 of Pulse Engine Documentation 6/4/2012 said that I connect this pins to 3V3.

¿ Where I found 3V3 in board ?

¿ Can I use another 5V external power supply for make this connection ?

¿ Where I found Ground connector for equiparate grounders ?

I don't like idea that connect pull up resistors to 3V3 USB Power Supply.

I would like use external fuse protected 5V Power supply. Is posible ?

Thanks.

PoKeys / Pin 53,54 and 55 in Pokeys56U in Step Pulse Mode

« on: April 16, 2012, 04:47:24 PM »

Hello I'm drawing a schematics with OrCad and I am making a component Pokeys56U in Orcad library.

I will use in Step Pulse Mode.


I only have 3 things to clarify:


in Page 70 of PDF User Manual 5/2/2012:


pin 53 - Conection Signal

What is this ?


pin 54 - Configuration Reset or Special Functions

How make a configuration reset or what type of Special Functions are ?


pin 55 - Connection signal

What is this ?



- Pokeys56U Board arrive at my home today. All perfect. Board is really little and compact. Is perfect for make a custom mother board and put it on.


Thanks a lot for all.

PoKeys / MACH3 + Pokeys56U + 3 axys + 3 encoder (chanel A and B) for positioning axis.

I'm new future user of Pokeys56U (Pay but don't send still.

I'm planning my new CNC machine. Is a modified LPT1+Stepper Motor Machine, to convert to USB + SERVO Machine.

¿ Is possible connect 3 encoders (1024 pulse / revolution) to Pokeys56U for make a positioning of 3 ayis (X,Y,Z) ?

In the Pokeys Manual was writen (3 fast encoders and 1 ultra fast encoders)...... What but how much faster is for pokeys ? and what is ultra fast for pokeys ? (1KHz, 10KHz....100KHz ?) I need this data for make a timming aproximation for know MAX STEP/PULSE per REVOLUTION that I can do.

Thanks a lot.
I think is a good product.

Spanish / Mach3 a través de Modbus (RS232->RS485) control convertidor

« on: March 28, 2012, 01:04:41 PM »

Buenas,

Acabo de registrarme y estoy elaborando mi segundo proyecto de fresadora.

Mi primer proyecto lo basé en LPT1 con placa optoaisladora y control de los 3 ejes con STEP+DIR con mosfets y motores paso a paso.
Todo fué bien.

Ahora busco algo que me convierta el USB o el RS232/485 a STEP/DIR porque ya no tengo el puerto LPT1.

Si no fuera posible, me gustaría saber si hay "algo" para conectar el soft MACH3 al modbus de algun convertidor de frecuencia.

Muchas gracias.
Saludos
