finally used US Digital QSB..... it rocks

yes bill i am using the scales just for feedback and ensure the axis position. the scales will provide actual travel or position to my software and on that basis the software logic will control the...

@bill
what about DRO_Plus Project - by Tom Kulaga ?

in addition to that we can use W83629D and W83628AG to convert PCI to ISA so that we can use the card with the now days pc

humm..... thanks bill, i have not considered your delay correction method.

and yes what i want to do is read or capture the current position at the axis move and control the axis movement as per...

@Bill,
Thanks for reply. My scales gives 5V TTL output. and just to confirm and make my grounds clear which will take shorter time calculate the position one USB decoder or the PCI decoder. as i...

@bobsch

Only converting the signals from RS422 to RS232 or the serial is not the solution. Basically we have to decode the signals so that it can gives out the values and the direction(+/-). i...

@ al_the_man
please have a look on DRO_Plus Project - by Tom Kulaga, I want to do the exactly same but for the PCI. as ISA slots are now not available on the motherboards. also its not worth to use...

@ bill,
The PCI card is discontinued, and also its not only to apply something but to learn a bit out of that.

got some idea about LS7266R1...... checking out..............
Prompting from expert appreciated

:drowning: Now i have encoders as per attached document and need interfacing module :drowning:

@Bill

Can we have an interface with pc for an incremental encoder which gives RS422 differential quadrature output?
more details about the encoder as attachment

???????????????
IT DID NOT WORKED FOR ME. BUT STILL WORKING ON IT.

How do you have interfaced your Linear Encoder with PC (by means of Hardware)

tried the circuit with verniers too
but no data

tried to connect with Magnetic Encoder but no use:drowning:

DATA == Cha A
Clk == /A

Yes!!!! Phase A & B with TTL I am using Magnetic Encoder ME6012 { Data sheet available @ (...

Hummm I have gone through it before. But My LPT is already populated with relay board and dont have any chance to add an PCI LPT port. so no choice but to go for Serial one (USB / RS232).
I can have...

Hi All Gurus,
I am building a PC Based CNC and need some Data Acquisition through Magnetic Linear Scale. I am looking for any support :idea: from you to read the encoder signals through COM (RS232)...

Hi Bill, i think i have overlooked your attached link before. i was just looking for your circuit.

:idea:Also will you please suggest me any thing good for my Magnetic Scales. Can I read the same...

Hi Bill, Interesting Thread, But will you please repost the image..... I found a broken link here.

Also if can you please refer any PC Interface for Magnetic Linear Scales.:withstupi

DELEM OR GALIL ?????????????????????
BETTER????????
CHIPPER?????????
EASY?????????????

I know VB and can do much more in that. I can do control through VB. only problem is how to drive Steppers / Servo through PC.

@ Jim,,,,,
Let the machine build first and then we shall have a discussion how to make it safe.
and also if you can help me in the issue please do it.

is there any other way cause i have just saw that we can use micro controllers from old scanner and have control on steppers. the only thing is can we have real time heavy duty steppers on the...

Thanks but he talks more about making the machine and less about the electronics..... I will have the ready machine and only want to do electronic and controller stuff........

Friends, I am planning to have press brake at my company and it will be better to have CNC press brake ( at least NC).
Basically I planned to buy a simple manual press brake with out any kind of...
