So I've done a big job with my machine, and i was having issues with the return to dig not functioning properly. In the mornings before i worked the machine hard the return to dig feature would work just fine, but it seems after i would work it hard, and then tilt the bucket down, and rake dirt forward or backwards the return to dig wouldn't function properly.
So for example, i had a soft spot, and wanted to fill in the hole with some dirt, so i get a bucket full of material and dump the material down before the hole and with the teeth i would drag it over top of the dole to deposit it in as i drove forward. Then i would go to try and return to dig so i could get my bucket flat to dig out another bucket. Well, kick it into the detent, and it would immediately cut out. Or go for a split second and then stop. Not in the desired spot where the sensor should kick it out.
But at the same time, if i took a bucket of material, and just carried it out and dumped it, the return to dig feature would work just fine.
I'm not sure if this has anything to give more incite. But i did notice that lowering the lift arms down, to lower my bucket to the ground has lost some of the accuracy. If i barely push forward on the joystick, it drops extremely fast. It feels like the valve isn't gradually opening, instead it is going from 10% open to 80% open in a very short span.
