Hi all, I've just set up closed loop control of the spindle for our machine - we haven't yet built the new control box so I've just been experimenting with the correct software set up for what is planned.
I'm happy to have spindle speed control in the machine now and I've confirmed the control works with a combination of Hal scope and a real scope and signal generator. Motion is correctly delayed until the spindle is at speed. What I expected to also happen at this stage was that the machine would stop if the spindle speed dropped out of range or stopped - but this doesn't happen. I ran the splash gcode in axis, provided the appropriate spindle speed input signal from the signal generator after the motion paused to wait for the spindle at speed signal, then motion began. Once it was 'cutting' I stopped the spindle signal to see what would happen and it continued cutting. Is there a way of making sure no harm comes to the work/tool in the case of the spindle stopping or slowing down substantially? Thanks in advance, Best regards, Ed ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
