General Mach Discussion / How many steps should I use?

« on: January 21, 2017, 10:38:25 PM »

I'm almost finished with my mori sl1 retrofit. My Servos are factory set at 2000 steps per revolution. I can change it to upwards of 16,000 steps per revolutions. It's a 3 to 1 gear reduction.  Not sure what pitch my ball screws are. So what should I use as steps per revolution? I know how to set them up in Mach.

General Mach Discussion / Re: PLC Tool Changer Help. Where to Start?

if I'm using a PLC then I know how to program that. I just don't know how to program mach 3 or setup modbus.

General Mach Discussion / PLC Tool Changer Help. Where to Start?

« on: January 15, 2017, 12:16:19 PM »

I'm retrofitting a Mori Seiki SL1. I've figured out how the tool changer works and how I'm going to program it with an Automation Direct Click PLC.

I have no idea of how to start with Mach 3. There's so many ways it seems that you can do it.

Basically my PLC with take a signal from Mach 3 and the plc will do the tool change and send a response to Mach 3 when the tool change it complete. I know how to program the PLC, but not Mach 3.

From reading I think I need to setup ModBus between Mach 3 and my PLC. So does that mean just a serial cable from my computer to the PLC? Does it bypass my Pokeys 57E completely?

Then do I need to program macros for tool changes?

Any help would be appreciated.

PoKeys / Pokeys 57E w/ M16 BOB Limit Switch Wiring Question

« on: January 09, 2017, 11:44:10 PM »

I'm using a 57E Pokeys and an M16 BOB. For the limit switches I understand that Pokeys now supports limits being used for home limits as well. On the board there are X, Y, Z and A inputs for wiring the limits. Obviously daisy chain two together per axis.

But what I need to know is one wire goes to the pin for the axis, but where does the other wire go to the "GND" pin or the "5V' pin? Thanks.

General Mach Discussion / Re: C10 BOB use with 12VDC Relay

« on: December 26, 2016, 02:40:52 AM »

That's not what I meant. The VFD is controlled by a C6 board which is it's function. When I'm switching a motor on, I use motor contactors; I mean when it's a heavy load motor.

For my mill it's just a simple aquarium pump at 120VAC.

For my lathe it'll be motor contactors for the coolant pump, spindle coolant/oiler, hydraulic pump and auto oiler.

I use automation direct for most of my electronics that deal with automation. SS Relay DIN mounted is $20.

Yes I'm thinking of using a Solid State Relay.

Its just a 120VAC aquarium pump, but that's for my mill as I'm rewiring it in a new cabinet. Before I had it hooked up when the VFD turned on and I didn't like doing it that way.

I will need some SS relays for my Mori SL1 that I'm retrofitting. It has a real sump coolant pump 220VAC, not sure how many amps though.

True. Thanks.

Hmmm ok. Kind of thought so. Thanks. I already have 12V in there for the VFD so that's not a problem. Probably easier to find a DIN Rail relay that operates on 5V.

General Mach Discussion / C10 BOB use with 12VDC Relay

« on: December 24, 2016, 03:34:30 PM »

How do I wire a 12VDC relay with the C10 BOB. I'm using a 12VDC relay for my coolant because it's DIN rail mounted. Is there a way to do this?

PoKeys / Pokeys 57E and M16 BOB How to wire to turn coolant on with a 12V Relay

« on: December 23, 2016, 05:52:34 PM »

Title says it all. I've got a 57E and M16 BOB coming to convert my Mori SL1 CNC Lathe and need to know how to wire the M16 to trigger a relay who's coil is 12VDC. Thanks.
