Hi, I think that you should connect hal and not halui pins to gearbox COMP for machine control. I thing halui pins intended use is for the user interface, hardware and software.

Controlling the spindle from an independent bouton and from the rest of the software with or statement needs more thought.

Mark, can you check in your machine if this is ground?

Can you take a close photo to transformers connections?

Hi John, thanks for your input, you are right about that. The relevant spindle control nets which I currently have are these:

Code:

net sig_get_commanded_speed  mh400e-gearbox.spindle-speed-in-abs  <= motion.spindle-speed-out-abs
net sig_return_actual_speed  mh400e-gearbox.spindle-speed-out     => motion.spindle-speed-in
net sig_return_spindle-at-speed  mh400e-gearbox.spindle-at-speed  => motion.spindle-at-speed
net sig_stop_spindle         mh400e-gearbox.stop-spindle          => halui.spindle.stop
net spindle-on               motion.spindle-on                    => hm2_5i25.0.7i84.0.2.output-13
net spindle-cw               motion.spindle-forward               => hm2_5i25.0.7i84.0.2.output-12
net spindle-ccw              motion.spindle-reverse               => hm2_5i25.0.7i84.0.2.output-11

And here are the functions which I have had to comment out due to conflicts.

Code:

#net maho_panel.r0c3_sig-out maho_panel.key.r0c3                  => halui.spindle.stop
#net maho_panel.r2c4_sig-out maho_panel.key.r2c4                  => halui.spindle.reverse
#net maho_panel.r4c1_sig-out maho_panel.key.r4c1                  => halui.spindle.forward

I used the halui.spindle.stop to give the gearbox control of stopping the spindle. Since there is no motion.spindle-stop pin, should I have the gearbox net to the motion.spindle-on pin and setp false to stop it? Or just have the gearbox comp setp motion.spindle-on false, from within it's code without going through a net?

Hi John,

Lucky my new bellows have not yet arrived, so I still have the guards off and can easily remove the cover and photograph the transformers. Will probably have to wait for the weekend though.
