Does it do this when you power up the machine and then home it the carosel just keeps turning.
I hava a sharp 2412 also if i power up the machine and the machine says ready i must wait until i hear 2 clicks i guess there contactors kicking in. Now if i home the machine before i hear these 2 clicks the tool carosel will keep turning untill i power down the machine or push emergey stop . I asked Charlotn lu at sharp about this and he said the control says its ready before the machine is .I just have to wait about 15 seconds after machine says ready before homing.
Second , there is bolt sticking out of the carosel when this bolt passes by ,a proximity switch the tool carosel should stop
When the bolt passes the prox.switch if its working right you will see a green light golw on the switch. if you don't see the green light as it passes the bolt the prox switch may be bad or need adjusting.
