Firmware uploaded to Melzi board but seem to have problem with bed leveling sensor

Posted by Richard_Brown 
Hi there ..If you checkout my other posts you will find I was working on getting the Melzi controller board of my Tronxy 3D printer updated so I can install bed leveling. Well, I got the Melzi V2.05 board updated with the latest firmware..1.0.3 - machine type Meldel. I installed a bed leveling device on the side of the extruder..it is of type Auto Leveling Position Heated Bed Hotbed Sensor. I have a Tronxy 3X and I have seen other Tronxy 3D printers come with this sensor. It seems thaton the first and then the sensor does not turn on. and the extruder just keeps going down.. (ouch!!!). So my question is there a configuration setting that need to be set to ensure the printer sets the bed leveling sensor on. I see that when you start a second print it does do this,and is successful every time but sometimes the first print this setup action does not take place..

Thanks hope you are all doing well.
