Hi I have a Boxford A3HSRi which keeps diving into the work and aborting saying "Axis overtravel, machine requested to move to x= 123...
I have also noticed the spindle collet and casing getting hot - nearly too hot to touch. The spindle clamp and gantry get warm but not hot.
Boxford say its a motherboard issue. £1500 to replace so thought I'd see if anyone had experience of this before I spend money!!
Ant comments gladly received!
I have no idea whats inside your machine, maybe somebody will help there. But basically you rip out the main board fit the new one inside or make a separate housing, read the manual of the new board, connect the stepper drives to the board, connect limit switches, connect buttons to inputs, map inputs in Mach 3.
You will need Mach3 also. That's the program that most people use for CNC, its inexpensive , has great forum, ...
If nobody knows more details, basically i will help you. You will need to open the machine control box? and take some pictures, of the board, drives and motors.
Are these any use? They are integrated behind the machine.....
Now, now, you will need schematics for the machine, but it seems the board with the green lights is the motor drives combined in one board, the one at the right side is the motion control board and the small one should be some termination boards for inputs and out puts.
So at this stage you are pretty sure the board is faulty, right? No way to take it down send to them and they repair for cheap?
If the answer to previous is no, then you need to ask them for the schematics so we see what type of signals it sends to drives, at what voltage and so on, also what else it does and what cables enter and go out from the board. Now somebody experienced with retrofits in your area could figure which is which and what is what very fast.
If they don't send you the schematics the thing to do is see motors name plate, figure motor size, figure at what voltage are driven / transformer output/ rip all out and fit all in one board like that MX3660, its breakout board and 3 drivers integrated. Its LPT compared to the one i said before which is Ethernet but has drives integrated and from all reports is a very nice combo.
All 3 motors have these numbers in common: 190\500ST-MTR
X axis has more info....Y200-2240-0410 AY04. no idea if thats any clearer.
At this point I havent got a picture of the spindle wiring - pos tomorrow.
However it's probably a good idea to either get you over from Spain (!) or find a local engineer. Assuming an engineer will charge minimum £500 + controller £250 + software £150 I just wonder if its all going to get a bit near the cost of a motherboard from Boxford?!
