Hi Gabi,
If the motor is a DC motor keep it and make suitable controller for that.
The PC Turn50 that I had was controlled DC motor, I have sent drawings, pictures and schematics to Dan. The macro can be found here at this forum.

Cheers Bengt

Hi Bengt,

Can you send my that drawings, pictures and schematics to me? My address is: balsanu_gabi@yahoo.com. In the emco Yahoo group it is a guy Robin (very nice guy) which has converted his lathe and tool changer too for Mach3.

That I try to do.

Thank you in advance

Well that is with a stepper motor he is using, I think that one is easy to do and if there is a macro to run it so go for it. PC Turn50 was factory made with slotted disk and a controllerboard built in to the original controller cabinett.

Here you have to make your own disk so it is easier to use a steppermotor. You get much faster tool change with the stepper motor approach.

Exactly. i intend to buy from Dan his G540 unit with 3 motors (X,Z and tool changer). What else do I need?. How can I connect that optical sensor (with that slotted disk) with Mach?

Tak a look at the macro that guy is using, there you can see what port or ports he is using. Have you contacted him to get some pictures or can you see on the video how many slots there is. One is OK and do some math from that index. Look at the macro.
Cheers

Here it is that macro. I think that was made it by Graham but maybe I mistake. That disk has only 1 slot. Where I can find that DRO code for Mach?
Macro:
' Boxford 160TCL Toolchanger Macro.
'
' Works by turning CW to just past the tool position
' and then CCW into a stop.
' Axis setup as rotary e.g. move 360 = 1 full turn.



If IsLoading() Then
' Do Nothing, program loading
Else

' Dim Variables

Dim Num_Tools As Integer
Dim CW_Steps_Per_Tool As Integer
Dim CCW_Steps As Integer
Dim HoldingDRO As Integer
Dim Requested_Tool As Integer
Dim Current_Tool As Integer
Dim CW_Feed As Integer
Dim CCW_Feed As Integer

Dim moves As Integer
Dim total_move As Integer


' set up some vars

Num_Tools = 8
CW_Move_Per_Tool = 360/Num_Tools
CCW_Move = 10
HoldingDRO = 1050
Requested_Tool = GetSelectedTool()
Current_Tool = GetUserDRO(HoldingDRO)
CW_Feed = 1500
CCW_Feed = 1000
Current_Feed = GetOEMDRO(818)


' start tool change

Message ("Requested Tool No=" & Requested_Tool)

If Requested_Tool > Num_Tools Then
Message "Requested Tool No. too high, program stopped."
Code "M30"
End
End If

If Requested_Tool < 1 Then
'Message "Requested Tool No. too low, program stopped."
Code "M30"
End
End If

If Requested_Tool = Current_Tool Then
' do nothing
Else
' lets do some changing
If Requested_Tool > Current_Tool Then moves = Requested_Tool -Current_Tool
If Requested_Tool < Current_Tool Then moves = Num_Tools - Current_Tool +Requested_Tool

total_move = (moves * CW_Move_Per_Tool)+(CCW_Move/2)

Code "G01 x-10 F1300"
Code "G0 z-10"
Code "G91 G94" 'incremental & Feed per minute
Code "G0 A" & total_move '& "F" & CW_Feed
Code "G0 A" & "-" & CCW_Move '& "F" & CCW_Feed
While IsMoving()
Wend

SetCurrentTool Requested_Tool
SetUserDRO HoldingDRO, Requested_Tool
Code "G90" ' back to absolute movement
Code "F" & Current_Feed
End If
End If

' end of tool change

I have modified both an Emco 200 turn and an Emco compact 5. The turn 200 is full house, having the following: 8 station tool changer, parts catcher, pneumatic collet chuck, pneumatic tail stock and hydraulic bar feeder. The machine runs from Mach 3 but uses 2 break out boards. The sensors in the tool turret have been replaced with four 5mm proximity switches and I put together a macro (M6Start) that only requires the normal Mach tool number and offset code e.g. T101 for tool 1 offset 1. The sensors in the turret give the tool position in binary and the 24vdc motor is switched into reverse with  2.8vdc from a regulated PSU. This voltage will put the maximum wattage into the motor that will allow it not to burn out. The main drive motor was changed to a VFD controlled 2.2 kilo watt motor and the speed controlled by Mach 3. 
OEM Macros were also written to control the pneumatics and hydraulics.

The Compact 5 followed the same system, but the turret was modified and 3 proximity switches, to give the correct binary, were fitted to it. The same M6Start macro was adapted to provide for 6 positions, The original moter on the turret was missing and it was replaced with a generic part (Currents might differ from the original so I will refrain from publishing the ones I use0)

Hi Myford,

It certainly sounds like a very interesting project that you have undertaken.

If you have the time it would be nice if you could start a new topic on your Emco machines with some pictures and more detailed descriptions / explanations on how you have made everything work with Mach3.
