Homing to marks on X/Y and Switch on Z and PARK
Posted: Tue Aug 11, 2020 5:44 pm
I have sold the FADAL TRM to a local friend.
He will be putting it in and using it in his home shop.
The FADAL homes using reference marks (Typical on this machine) homes to the index pulse on the encoders.
His issue is that he can't leave the head up. I could probably change his Z home and relocate the marker tabs on Z. That would probably the easiest.
My other thought was that its pretty easy to add a mechanical switch to Z+ and let Z home as it typically would with a mechanical limit switch.
So my first question is, would it be possible for Z to home to a mechanical switch and then back off and search for the marker pulse on the encoder and still let X/Y home to the marker pulses on their respective encoders.
AND if this should be possible, can the PARK macro be modified to park the Z axis lower and let X/Y park close to their respective marker pulses as they do now?
I suspect its probably easiest to move the Z tabs and create a new Z home position and change the soft limits to - and + from that point?
I want him to park the machine before shut down, putting the Z lower than his garage door would open. (Yes he knows when he uses the machine he has to leave the garage door closed)
How would you handle this one?
Thanks in advance,
Marty
