From the base up to the tool in the following order: X,Y,Z axes are cartesian, then the rotary axis, then the spindle.
I'd like to hook up this rotary axis to the A-axis.
Problem is that this rotary axis has a pneumatic locking mechanism, it may only be moved when unlocked, and must be locked before further machining is done.
The lock is there because there to prevent play while machining.
What would be a good starting point to make this work?
I've read the manual section 3.1:
- Code: Select all
Current high/low port & pin: This is a physical output pin which can be used as an enable or a
current reduction signal for the external motor control electronics connected to the system. The pin
can be inverted checking the active low checkbox next to the textfield. The signal is active when a
motion or dwell is ongoing and activates a few milliseconds before the motion starts and
deactivates a few milliseconds after the motion stopped. The few milliseconds delays are to let the
stepper motor driver adjust the current in time to the full or to the holding current level.
It seems to me this feature seems suitable for this scenario.
Only the milliseconds delay worry me, pneumatics are much slower, the lock operates in the order of ~1 second.
So two question from my side:
1) Is this the way to go?
2) Is there a way to introduce an (extra) delay before moving this axis?
