General FAQs

Are the mill and lathe controls the same?
Very similar. If you can operate either machine fitted with ProtoTRAK it will only take a few moments to familiarise your self with the other type.

Do you need a CAM system to program ProtoTRAK?
No! However, ProtoTRAK will accept programs created on CAD/CAM for sophisticated 3D jobs.

How are programmes transferred on the Siemens and ProtoTRAK controls?
Although the Siemens control is equipped with a RS232 Port, it also comes with a much superior Ethernet Port. RS232 is now considered old fashioned, slow and not particularly reliable. Programmes can be transferred to and from the ProtoTRAK via a floppy disk, a USB thumb drive or an Ethernet Port.

How do I know XYZ machines are built to a standard I can rely on?
Most of XYZ’s machines come from one supplier with whom we have done business for over 23 years. Our business represents about 90 percent of their production so they have tailored their quality and standards to levels expected by European engineers. Our parent company, Southwestern Industries, and we are actively engaged in the design, specification and quality of the machines imported from Taiwan. All machines are fitted with European bearings, hand scraped to ensure the highest degree of accuracy, ball bar tested and laser calibrated. Our best confirmation of this system is that we have sold over 7500 machines since we introduced them in 1984 and most have been sold as repeat orders and are producing good parts today.

How long will XYZ support me with ProtoTRAK spares?
Our parent, Southwestern Industries, carries every spare for every ProtoTRAK ever made going back to 1984. Here in England, XYZ carries full spares for every one of the 15,000 ProtoTRAKs ever sold in Europe. We believe our customers bought their ProtoTRAK to enhance their productivity over the full life of the product. And we are committed to support them all the way.

How much extra output can I expect from a mill or lathe fitted with ProtoTRAK?
It depends on the type of work you’re doing. But research from the 7000+ UK users suggests you can double or treble your output, even more on complex parts.

I get a lot of repeat work, can I save my programs so that I don’t have to write them again?
Yes, either on the machine’s floppy disk, flash memory hard drive or on a computer.

Is ProtoTRAK more productive than other CNC controls?
For one-offs and small batch production, the answer is a resounding YES!

Is there enough memory in the Siemens control to run large programmes? How about the ProtoTRAK?
The Siemens 828D control that we use as a standard fit to our machines has 3.7Mb of internal storage for programs, but the control also has a front mounted compact flash card slot which will take cards up to 8Gb capacity. There is also a USB port for taking a USB stick and finally the control has Ethernet connection for connecting by cable or wirelessly to a PC or server. These external storage devices can be used as the primary storage and programs can be written on these media’s directly.

The Siemens 840 Control that we fit to larger and faster machines such as the VMC 1060 HS has an internal flash memory allowing 4Gb of program storage as well as the external devices such as USB port and Ethernet connection.

The ProtoTRAK control that we fit to our mills and lathes have 4 USB slots for program storage.

All the control systems that we fit can run large Cam generated programs from the storage devices that are fitted so even 3D type work can be produced with confidence on XYZ machine Tools.

Why are some other Mini Mills on the market cheaper than yours?
Because they are of lower specification. The Mini Mill 560 has 560mm x 400mm x 500mm travel on X, Y and Z. It has an 8,000 rpm spindle, more power, a 12 station tool changer, heavier weight and a much better and easier to use control. Even though we call it a Mini Mill, it compares very favorably to our competitors’ smaller VMC products.

Why do you only use Siemens controls on your VMC and TC machines?
The Siemens control fits perfectly with the XYZ philosophy of “easy to use” programming systems.  The ProtoTRAK is the easiest to use possible CNC in the market but is tailored to non-production applications.  The Shop Mill and ShopTurn features of the Siemens control apply many of these “easy to use” ideas to machining and turning centers and their production applications.  Transitioning between these controls will be comfortable and natural.  Neither control requires G Code or off-line CAD/CAM programming unless you want them and then they are happy to accommodate your choice.

Our Nationwide team of Service Engineers understand the ProtoTRAK and Siemens Systems, and they are supported by a 9000 square foot stores, offering spares from stock.

Why does XYZ use Box Ways on their VMC range?
Our standard range of VMCs use Induction Hardened Box Ways and Turcite coated anti-friction slide ways.  This design offers the maximum rigidity and vibration absorption – far exceeding what is possible for machines using linear bearing slides.  Machines using these linear slides are fine for light work but subcontract shops and companies who machine a wide variety of materials (from aluminum, to iron, to stainless) need a machine that will perform all their work.  Linear way machines are cheaper to produce and can have faster rapids and acceleration but we think these advantages are far outweighed by the superior cutting performance of box way machines.

We do fit THK high precision linear bearing slides on our 1060 HS machine that is designed for light cutting at high speed – a proper application for this technology.

Why should I pay more for your machine than your competitor’s?
We think that what is important is to help you lower your overall cost. One element of that cost is the price of the machine but it’s not the only one. We believe that the higher level of support and performance that you will receive from XYZ Machine Tools can significantly reduce your overall cost. Just a few ways are:

  • Better and more efficient training from one of our six applications engineers. This means that you are making parts and writing invoices faster.
  • Highly qualified sales engineers who understand your business. This means you get the right machine for your work that produces those invoices.
  • Better and quicker service form one of our eleven service engineers. And quicker part availability from our 9000 square foot stores. This means your machines run more and you write more invoices.
  • Rugged machines (see Q & A on box ways) and industry standard controls that hold their value through the years. This means that when you sell your machine its resale invoice will be higher.
  • The reliability of dealing with a steady, well respected company who has earned its business honestly and through its performance. You may not be writing any invoices if your machine is supported by a weak or Johnny-come-lately company that disappears.

Will I need training to use ProtoTRAK?
Not very much! If you can use a centre lathe or mill fitted with DRO then you should be producing parts confidently within hours.


Technical FAQs

The new Guardmaster Safety Relay (MSR127R) has completely different terminals to the old one (MSR6R/T) fitted to my machine; how do I wire up the new one?
In 2016, we updated the old MSR6R/T, Guardmaster Safety relay with the more modern equivalent MSR127R.  The function of the new safety relay is essentially identical to the old relay, but it has different terminal labels.  To assist you in fitting the new relay, please refer to Technical Bulletin 001, which provides a cross-reference table between the MSR6R/T and MSR127R terminals.  Do not forget the wire link between terminals S52 and S11.


Networking SM Controls: Why can’t I access files and folders on my SM Control from other computers on my network?
The operating system of the SM Control is not configured to allow sharing of files and folders on the Control, across the network. This is to minimise read/write activity on the system disk and so maximise the life of the compact flash.

You can, however, access shared files and folders on other computers from the SM Control. So, this does allow you, for example, to:
• Backup programmes, written on the SM Control, to another computer, or
• Open programmes, in the SM Control, written using the PT4 OFFLINE package on (say) a desktop computer.

What does ProtoTrak Critical Error 9232 or Windows Low Disk Space warning mean?
Critical Error 9232 means there is not enough free disk space on your control pendant to create temporary files used by the ProtoTrak control system. Similarly, the Windows Operating System flags up the Low Disk Space warning because there is less than about 1MB of free disk space.

These errors occur with early SX pendants, which have only 256MB of internal disk space (computer modules 24030-5, revisions B to J). All later revisions have a minimum of 512MB of disk space and so should never see these issues.

You may have such a computer module and never seen these errors until recently. Due to product improvements and enhancements, the latest software is larger than previous versions; leaving less free disk space. So if you have either upgraded software yourself, or purchased a Service Exchange pendant (which has the latest software installed), you may now be seeing these messages.

The Windows message usually appears at boot up. This message can be safely ignored. The ProtoTrak system does not need much free disk space to function correctly. Other than G-Code files (see next section) it only creates small files such as tool tables, configuration files and error logs.

Critical error 9232 is most common when STARTing a programme RUN. When you press START, the control generates a G-CODE file, from the ProtoTrak .PT4 programme, which is used by the motion control system to execute your programme. For complex programmes, this G-Code file can be larger than the disk space left on the early controls. Because the G-Code file could not be created, you may also see the related Critical Error 7207 (no part programme to run).

The solution to this problem is very simple. Although classed as a Critical Error, the error is not due to any fault in the machine; simply that there is not enough disk space.

If you insert a USB memory stick BEFORE starting the programme run, the control automatically writes the G-Code file to the USB stick (in preference to the internal disk drive). Providing the USB stick has at least 1MB of free space, the G-Code file will be created and programme RUN can continue as desired.

Note, if you remove the USB memory stick whilst the programme is running, you will see Critical Error 9231 (IO Error). This is because the motion control system accesses the G-Code file during programme RUN. If the USB stick is removed, the G-Code file is no longer available.

So, if you see Critical Error 9232: plug a USB stick into the control before pressing RUN and leave it there until the RUN is over.
