Thanks bassa for replying
my problem is i have l297 +l298 chips to control stepper motor with mach program and it did not work never i test my board with 555 timer and the motor run very well in the range of 100 Hz to 400 Hz and checked my parallel port and it worked well when i tried to...
Help on parallel port Pulse Rate monitoring
hii guys
i dunno if that where i should post my problem ,,,
i wanna to monitor my parallel port pulse rate which dont work with my l297 chip and
i used 555 timer and worked well in range from 100 Hz To 400Hz but the parallel port did not work with...
WIZPIC :) you are the man
I DO not know how to thanks you Really the Problem solved with turning mechanical layers off and a bout the scaling tomorrow i will match it with the IC's and any other components to figure out the correct scaling .
i hope to accept me as your a students...
Thank you so much :) i will try and error the scale until i can fit it and post the result
and last thins is the transistor out line is appearing after i turned off top overlay layer how can i fix that
you are great man
i did every thing u told me and there is no thing change :( i do not no from where came my wrong !!!!
and i print the circuit in 1 scale and it did not match the dimensions of the components !! ??
why is that too sry for buzzing you but i need serious help
thnx
i know the circuit gonna fit with the paper but is it gonna match the real dimension of he component's in 1:00 scale ??
and i clicked on holes and do not appear too
Thnxxx WIZPIC
the problem now is in scaling what is the scale of the page make it fit with the component's i tried a lot but nothing work
and when i choose holes option it not apear in print preview and if i clicked on top at components included
it's appear but with component's which i do not...
