Homing using Ref Home
« on: October 19, 2014, 11:59:12 AM »
Hello,

My Machine works well now, except, when homing the slaved axis.

The Y axis has a homing switch, agh Axis doesn't, when i select Ref Home the machine homes and then moves away from the switches, all seems well.
The problem is:  the A axis is slightly out of sync with the Y axis, and each time i ref home the error it is out by the same amount again, its about .6mm out each time i hit ref home button.

The machine is pulley and belt driven so if i Ref home 7 or 8 time in succession, the machine jumps a tooth on the pulley.

Could the Y axis motor not be in sync with the A axis motor?

If not any ideas?

I am using a UC300 controller from cnc4you

In General Config, do you have "Home Slave with Master" checked? It needs to be.

Could be an issue with the plugin for your device.

I have just updated the driver and firmware just in case.

If I disable the slave axis, and unplug the motor it works fine

everything else works ok, the machine will always go back to working zero fine, and I never have any unexplained stops, so there is no problem with noise
