i need someone to help me doing an automatic length stop with a digital read out ,
a lenght stop :http://www.promac.co.uk/visual-rf.aspx
so i need to entrer a distance (example : 605.55 in mm) the stop will move to that position(conversion of the distance in steps depending on the step motor step angle etc ),a single dimensions will be processed at a time .
an lcd to show the input , the actual position , the target position ,
will be 2 mode of inputs , the absolute position ,or the relative position
absolute position is related to the origin and relative postion is related to the actual position.
the keypad 4X4 matrix
maybe 2 limit switches to reset the length stop position .
the length of the machine is maxim 3000 mm
with a ball screw can achieve 0.01 mm per step and i dont need more then that for a mitre saw .
the hardware is not fixed and you can choose whatever you want .
optional maybe command for a relay after the destination is reached (blocking the stop at the desired position).
hope is clear enough, if not let me know i will try to clarify.
if you can do it let me know since i cant , im stuck in the conversion of the input from the keypad to something that i can use for the calculation of the steps
this is not for free i will pay for it after conclusion that is what i need and is working.
best regards and thanks in advance.
