General Mach Discussion / serial io extension board info request
« on: November 19, 2012, 03:41:34 PM »
hi everyone,
can somebody guide me about designing and building an extension serial board(the principals behind the mach3 for interacing my own board) or introduce me somewhere to obtain schematic and code for such a thing please?
thanks.

thanks everybody,
dear hillboy is this the diagram of a brekaout board which had worked in a real machine.if so can you introduce me the source site for that.
thanks

yes exactly , there will be encoders for feedback.but as i said does the frequency counting will do the job (specially for slow steps).or there are more complexity in the breakout boards.do you have any circuit or idea for this job? if so can you please share it with me

do you mean that i can use a frequency meter to convert the step pulses to analog signal to control the velocity of a DC motor and is this the way that companies like rotex are using in their breakout boards.. if this is true there may be problem for slow signals because of the delay of frequency calculations.
thx.

can you explain me the signal specifications of step and dir signals please. and do you know anywhere in the web where i can find schematics to build the required boards myself.
sincerely yours.

General Mach Discussion / question about analog input servo drives
« on: February 02, 2009, 03:49:07 PM »
hi everybody,
i'm new to mach3 and i am very intrested about it. i wonder, if mach3 can control servo drives with analog input,say +-10V, and if so how ?
can somebody guide me about this question.
thanks in advance.
