Advice Needed, Converting a Boxford VMC 190

[swood1]

The Bradford instruments board is possibly also a limit switch interface, the ribbon cable is labelled PL1 fast serial link at its connection to the main processor board and contains very similar components to the main processor board.

I have the original manual for both the 160 TCL and the 190 VMC, the manual for the VMC says the small board is the 3rd axis microprocessor board.

Do you have yours running with original software?

Hi Everyone,

I am trying to convert a Boxford VMC 190 using aCNC-USB box from Eding. I found that the output voltages to the motor drives from the boxford processor (xd, xc, zd, zc, cl5 and cl6) and the Eding CNC-USB box to be similar. Since the eding software has some setup functions it is also possible to tweak these voltage vales to match the Boxford processors voltage. While I still haven't checked the spindle voltage levels, My idea is to simply replace the boxford processors pins with the Eding CNC-USB box pins since the signals they both output seem to match. However I am new to this and any advice would be great. By the way do any of you guys have the hardware wiring schematics of the Boxford VMC 190?

Hi Subash,

I am not aware of Edin or CNC-USB. For mine I ended up using a Ethernet Smoothstepper and a PMDX-126 Breakout board. I removed the main processing board but retained the board with e stepper drives on and tapped directly into that. With this I have obviously lost my tool change facility and the ability to use the control panel on the machine but I can atleast run the machine as a CNC machine including spindle.

I need to learn more about how to setup the I/O on the breakout board, maybe then I can work out how to integrate the emergency stop etc.

But overall I believe the best way to actually upgrade this machine is to do what others have done and that is to rip out the whole interior and upgrade the lot. This will unfortunately cost a bit of money if you want Gecko drives etc.

Regards

Steven
