Boxford vmc260 to mach3 conversion
« on: March 11, 2014, 01:22:54 PM »
Hi there...
I bought a Boxford vmc260 last year, used it with the Boxford software but found it very slow and limited so I'm going to upgrade to mach3 control.
My machine has Parker stepper drivers and a get Gemini speed controller, does anyone have any information on converting this machine using these original parts and preferably a smoothstepper board?

I responded on the zone. Post pics of the mechanicals and the electronics. Surely we can figure it out pretty quick.

   Though I am going to check it out on your link. Try using tapatalk and post the pictures direct on each forum. Too many times I have seen the host site change or whatever and the pics disappear for future users. Plus people are more prone to help if they see the items right in front of them. For some strange reason I was under the impression you were using your phone to post.

There is a link to someone using the same driver here.

Have you thought about what BOB and such you plan to use (smooth stepper)? You could reuse all of your power supplies most likely. The Gemini speed control board probably has its own 0-10v supply which can route thru your BOB depending on the model you choose, if not you can add a board that will output the signal required CNC4PC offers a few different types as do others.

How does the computer tie into that machine? Parallel port?

At the moment it is through a serial port,  I was thinking of using a smoothstepper,  maybe with a Campbell or cnc4pc bob. Guessing most of the original electronics are unnecessary.

 I would take a look at the CSMIO/IP-M, it negates the need for additional spindle speed controllers and breakout boards etc and also has analogue inputs for feed override pots etc and the I/O is 24v which is more in line with industrial practices.

Thanks for that,  hadn't heard of that one. Looks really good and the user manual is really comprehensive. Guess first step is to strip out all of the unnecessary electronics,  keeping 3x stepper drivers spindle control board and psu. Do I need the two breakers shown in the pictures above?
Also would you advise installing mechanical limit switches or just use the proximity homing switches and software limits?
