Hi, I am in the process of bringing up a Denford Novamill that I bought without electronics. I have built a driver system using drivers / PSU / BoB from fleabay and all seems to work pretty well but I seem to have hit a brick wall with homing.
All the home switches (installed at manufacture on the mill) work in the same way - a n/c switch that opens when activated by the axis reaching the end of its travel. I have used the autosense feature on the config/ports&pins/inputs menu to set these up so I guess they should work OK. On the Motor Home/Softlimits menu Autozero is unchecked for each axis; the X axis is checked for Home Neg but the other two axes are unchecked (all to correspond with which way they move).
Now I find that on a "reference" request the Y and Z axes function perfectly, running to their limit until the switch opens then reversing and running slowly until the switch closes. However the X axis just moves a very short diatance, wherever it is, then stops and the green homed LED for it lights up.
I am wondering if there could be a noise problem on the X home switch wires. Does this sound likely to the experts please? At the moment the input debounce interval is set to zero, and I notice that in response to a home-related question Hood recommended that this should be set to around 1000, which would correspond to 40 ms - is this likely to be a possible fix please?
John.
