99% success with cheating,
Hi Foozer...Kids are more important than anything else....good luck with the washing machine.
Played around this morning adding and subtracting bits of code...use some of Foozer's and hashed it around a bit....Success with first upload....yahoo...just one glitch....set 90 Degrees on the controller and rotary table turnbs 45 degrees does same for every abngle setting...cuts it in half.
Spent rest of the day so far changing parameters for Table Ratio, Steps per Rotation etc, checking over and over the sketch.....wont turn table past 400 step setting with table ratio reduced from 90...back to 72 or 36....adding in the calculation etc...no success.
I have cheated a bit now to get 90 degrees to turn 90 degrees....did this by editing 360 degrees on sketch back to 180 degrees ....table now turns to whatever degree setting I choose...Awesome.
Would still like to get the sketch fixed without the cheat but I have looked and looked with my untrained eye and can't see anything oout of place.
Here is the sketch......big thanks and appreciation to all those involved....I learned heaps as well....patience from people won out in the end.
