IF anyone is interested in using the Bijur type auto luber here is teh code to make it work. It is based on motion. If any axis has motion then it turns on teh timer motor . It only runs if there is axis motion. You add this code to your HAL file and set the pin number to what you plan to use. THis is not totally my code . I snagged a bit of it off the net then modifed it to work with PP and a mesa card (7i80)
