Centroid Community CNC Support Forum

Hi I have a Bridgeport clone milling machine with MPU11 / DC3IO driven by Mach 3.

I have just acquired a Nikken CNC 150 rotary table.

Can the DC1 in conjunction with the MPU11 drive the CNC 150 using Mach 3, if so, please can you tell me what the pin connections would be.

I am assuming that the valve for the air supply is controlled from within the rotary table unit rather than needing an external valve of some sort.

Thanks

Hi Paul,

Yes, you can run a rotary table with a DC1 connected to your DC3IOB.
I can't say whether the DC1 is suitable to run the motor on your rotary
table without specifications however. The DC1 can run anything the
DC3IOB can.


Connections are:

1. A communications cable the plugs into both DC1 and DC3IOB
2. Servo power for the DC1 (can be supplied either "piggy backed"
from the VM+ & VM- on the DC3IOB or from a sep. supply
3. Motor power connects to the DC1 on screw terminals just like DC3IOB
4. Encoder for rotary plugs into an open encoder input on the MPU11
5. Clamp for rotary table gets wired into OUT30 (Rot Clamp) on DC3IOB

Building macros to operate the clamp in Mach is trivial:

To turn output 30 on with M10: (save as m10.m1s in c:\mach\macros\mach3mill\)

SetMasterOutput(30, 1)

To turn output 30 off with M11: (save as m11.m1s in c:\mach\macros\mach3mill\)

SetMasterOutput(30, 0)

NOTE: The air clamp on your rotary table may be "normally clamped" (without air on)
in which case you would turn the output on to unclamp or it could be setup in the opposite
manner in which case you would turn the output on to clamp. Test it to determine which
you have - you don't want to burn up your clamp, motor or drive running the motor against
the clamp

Hi

Is the DC1 in stock?

I ordered one about a week ago and havent heard anything yet.

Thanks

Paul

Paul,

Yes, they are in stock.

I sent you an email shortly after you ordered it regarding shipping fees.
($45 USPS to UK) I just sent another to the email I have on file. If you don't receive it,
please let me know ASAP
