Hello !

So, now axis motors are OK, home limits too, and after 4 hours, my VFD ATV12 is ok too ! All move, no problems, it's perfect !

Now i work on turret, and i'm waiting for spindle encoder (1 month) to finish !

@martyscncgarage, your youtube vids and advices are great, so many thanks for them.

For my milling machine, I have a NVEM breakout board, it's a nightmare with it, centroid is so simple to configure... I think I will buy other acorn BOB for it.

Great news Gordon! Keep after it!

Hello again :)

So it was my bad, relay wiring correctly, but power source was too weak to active it. No problems now with relay, when Led is green, turret rotate, when red, rotate backwards against the pawl and stop. I follow emco original schematic for relay, not acorn one.

Gordon, if you were the one that asked me about this on the Emco CNC Users Groups.IO forum
Your turret sensors are running at +5VDC and Acorn input logic is at 24VDC. Disconnect those sensors from Acorn.
(You mentioned Tool1 is working but the "Counter" is not, it now may be damaged but repairable)

You could use a couple of these:  HiLetgo 2pcs 5V One Channel Relay Module Relay Switch with OPTO Isolation High Low Level Trigger

PLEASE post a good high resolution picture of the sensors on your turret. See if there is any writing on them, or if there is a PC board, take a good high resolution photo of the board the optical sensors are on.

As for the motor wiring, I am still a little concerned that the motor is operating at 12VDC forward and Reverse. But perhaps Emco specified the motor to work that way. Feel the motor after a bit to see if its hot from being stalled at 12VDC against the pawl.

Yep it's me on emco groups.

Here is pictures of sensors and board. 2 sensors are same markings.

Motor not hot after a bit, but not very comfortable with this system... If Emco use it, I think there is no problems...

Edit : sensors disconnetced when you say to me.
