Creating arduino/esp32 code for broken bottle stickering machine.

We have a bottle stickering line where bottles go over a Assembly line where the bottle goes through a product sticker (marked with a laser sensor). when the laser sensor has been triggered a new label will be pushed foward for the next bottle. This system is now broken. This works with a HMI touchscreen. The manufacturer does not respond back, so we need to make a new solution. I am thinking about a arduino/esp32 for the coding. We have relais, the wave a plc controller type: DVP-14SS2 (if even needed) We have a large steppenmotor and a label reading unit (that can be ignored if we use the sole steppenmotor). Can someone help us with this so that the sticker unit can work again.
We have many more projects within our company, so it will be a longer cooperation.
