HI To all,
Thank you all for replying to the post and offering fantastic support. LACanteen thank you and thank you all for directing to call Crane as well. The short of it was that we had 2 bad picker cup y homing switches initially, The last one installed had the switch blocked by the packing tape. *doh* self inflicted.
The Long if it:
After talking with Crane, they let me know that there were several issues I had described, but we will focus on the one caused by the y homing switch under the picker cup in further detail below. The others are well beyond the length of this post and I do not want to “muddy the waters.”
The Deeper detail: Crane informed me that the machine has the ability to “function” with a disabled/broken y homing switch, but the offset will slowly drift, eventually causing non-vending. The way the machine does this is using the other sensor data, drop sensor in the cup and port door sensor and x/y position. The vertical drift in the shelf slowly increments in the controller till the vender just sends the picker cup all the way to the top and slams the assembly to the top or side no matter the selection chosen. This is because the homing switch acts as a “reset” to say “you have arrived reset yourself”
Thank you all again for your expertise and feedback.
