Hi Tom,

I have looked through some example C programs for coordinated motion, but because I am not a great programmer I wanted to ask for your guidance.

My machine has a tool change routine which is a C program, but there is a portion which needs to make a coordinated movement of 2 axis. Is there a command line I could use within the C code to accomplish this?

Thank you,
David.

Hi David,

What type of coordinated motion do you need to do? For a real basic
motion you might just command both axes to move independently at the
same time. However the motion may not be in a straight line unless the
Jerk/Acceleration/Velocities are scaled properly for the direction.

Otherwise I've attached an example to use the Coordinated motion buffer.
Note these files fix a bug vs the example files included in V4.33 so
use these instead.

Hi Tom,

Thank you for the files.

The motion uses a motor to lift a horizontal platter with a jacking screw, but once raised (clear of locating pins) the platter needs to rotate (via a separate motor/belt drive). Once the platter starts to rotate it raises/lowers on the jack screw so I need to slowly rotate the jack screw while also rotating the platter to maintain clearance above the locating pins.

So to summarize, I turn the jack screw to raise the platter, slowly rotate the platter and jack screw together and then turn the jack screw to lower the platter back down onto the locating pins.

Hope this makes sense.

BTW your email shows you sent it Saturday, but it only arrived in my Thunderbird (mail not car) about an hour ago. Strange.

Thanks again,
David.

The bug only relates to doing Coordinated Motion from within KFLOP using
the attached User Program Example. See the files that were attached for
the corrected example.
