Thanks for the interest shown in this post. Here are the three circuit drawings. There really only needs to be one combined drawing but I have broken them up in three because that's how I built this project, a Control box, a Stepper control box and a Limit control box., the last only being used when it is required to set the table stops. The circuit could certainly be refined but as I am not into production with these, as long as it works then I'm happy.
I have included a drawing of a latching relay circuit for those that may not be familiar with them.
The following notes will help understand the Limit Control box:
i) Relay 1 will latch when HOME limit switch makes.
ii) Relay 2 will de energise when PUSH is pressed. This will cause the stepper to rotate CCW and unmake the HOME limit.
iii) When REVERSE limit switch unmakes, Relay 1 will unlatch. This will energise the stepper to rotate CW until HOME limit makes, causing Relay 1 to latch. The stepper will stop and the green LED READY will illuminate. The circuit will now wait until the operator presses PUSH, whereupon the cycle will repeat.
I will try and upload the video by tomorrow.
Cheers, Peter
