Hi Dan,
Sorry to say but I have never seen Emco ATC that is solenoid driven, the one I have been playing with is DC driven with toolchange rotation clockwise seen from the chuck and locking counterclockwise with a ratchet/pawl. If you have the original mechanics I suggest you stay with the original setup as intended as you will get problems with the gearing ratio so the stepper will probably not hold the tool in position without mechanical aid = reversing - using the ratchet/pawl for locking up the tool in position.

The macro was written for PC-Turn 50 so it is possible that you have to modify the code. Sorry to say I do not have the lathe anymore so I cannot not help you on this.

The DC motor goes full voltage clockwise and reduced voltage with polarity change in reverse as it holds the tool in position all the time it is powered up, this is how it works on the PC-Turn 50.

Hope this helps
Cheers Bengt

Do you know what the voltage and current requirements are for the dc motor?

Hi Dan,

I believe it is 24V. I should have a schematic for the toolchanger somewhere.

Cheers,

Peter.

Thanks. Looking forward to seeing that schematic.

On my Emco Compact 5 it is a 12VDC motor. I used two relays to switch the power polarity to the motor in correspondence to a signal from Mach3. The reverse polarity being simply fed through a resistor. I used a slotted disk on the back of the turret shaft and an optical sensor to count the tools, and I have simple macro to control this.

 You are correct. I checked the toolchanger with a 9V battery and I see that it runs one way into a stop and the other way continuously. There are no other wires for sensors to determine what position the tool changer is in. So it looks like I would have to add the optos.
Thanks for the info. Would you please email me the macro you used for the tool changer and do you have a schematic of how you set up the two relays?
TIA
Dan

Dan,

Tell me to which email address you want me to send you the macro.

Email the macro to dmauch@seanet.com
Thansk I appreciate this.

Hi to all,

I think I am Dan customer. Anyway if I am not, I am in the same position. I do have that kind of lathe with tool changer and I want to retrofit to be driven by Mach3.
I intend to use one of Dan units (G540). What else do I need?
Seems the biggest problem it is that motor on tool changer. What do you guys recommend in order to have a proper working machine?
