I am new to this like all of us at first. I want a rapid over ride as well as feed over ride to use on my boxford tcl 125. is it possable and how can some one put me in the right direction please. I am using modio board and 2 of the analog ports with 12 steps on the feed pot with resistors between steps to give me 10% steps and 4 steps on the rapid so i get 25% on the rapid so i get 0,25,50,100 this would be great to testing out programs so it does not rapid in to jobs.while i,m on the subject the other thing i what to do is set up the turret to work on my lathe as well. it is a 8 station turret that is stepper driven . it index's just past the station the reverses back to lock. it has no feed back ( i think i can rig something up if needed) how do i go about this as well please put me in the right direction.
