New stepper motors are no expensive these days ... probably worth picking one up ... I've a stack of old Taig stepper motors and dropping the new ones in allowed increasing the speed and acceleration...

Yes those are the 'rapids' ... basically the fastest speed the machine can run at They look reasonable, but as you say, after 10 years things may need an overhaul. Missing steps is the most likely...

Rapids and acceleration are set in Mach3 ...
Settings -> Motor Tuning -> select Z axis

Being 10 years old, the motor magnets may be getting a bit weaker, and the z axis may be a bit tight...

https://medw.co.uk/wiki/Taig+MPS2000+MaxNC+mode+on+Mach3 ... although I probably need to check the links still work!
Kurt is still supplying the Step and Direction board that converts the 2000 to a...

Trying again as previous post would not submit!
Andrew ... I may be able to help out with a step and direction board for your box ...
We hook the fan to the centre tap on the trannsformer by the...

First thought, have you checked the internal fuse? The high voltage supply has one hidden away inside the box ...
Next question ... are you using the MPS2003 software or Mach3? What speed is the...

I'd start simply swapping the X and Y driver connections ... you need some reference and if the fault stays with the x axis it's more likely to be the motor/mill end. If it swaps to Y then change the...

Kurt designed the driver using 'real' components, so it's easy to replace a FET if one blows and the current limit is just a resistor as far as I've established. We never did see the actual circuit,...

Paul714 ... there are no current settings on the Taig/Microproto drivers, they are built for the motors as supplied. And for some reason I'm not seeing any pictures just to confirm if they are...

Just went to the file which it SHOULD still be in and i's missing :( I know MPS2003 backup is on the system, but not sure if I ever uploaded MPS2000 ... I'll have a dig ... Mach3 will drive 3 axies...

Andrew, the fist question has to be what part number are the stepper motors. So you can work out what current you need. Some of these older systems were 'unipolar' and the wiring of the motor is not...

Even a small cutter can move the head against any play in the z-axis. Obviously if the cutter is pulling down into the work it should be less of a problem, although it can move the head down the...

Magnets get weaker over time ... and newer motors have even more powerful magnets so simply replacing the motor should be better then it was when new

Sound simply that you are expecting too much from the stepper motor given the weight it has got to move. Since I see a Mach3 screen in the background, I'd start by setting jog speed to 10% and check...

Quick response while passing ...
The problem you have is not so much the motor as the driver. The TB6560 driver works well at the lower speeds as your Ali machining testifies, but to get higher...

The single parallel port indicates this has the step and direction board fitted and the extra DIN socket on the top corner has a few extra connections to the parallel port. Pinout SDBoard...

You say C10 board but that is NOT a USB breakout board, it's a bog standard Parallel Port one, so are you simply using USB to provide the 5V supply? From the first message it sounds as if you have...

For the 2000LE controller, 'Step Low Active' should be a cross on all channels and step size in motor tuning is 10uS.
Dir Low is a tick for X and a cross for the other three channels.
Bare in mind...

Good point. The original threads are different hands for X and Y so in manual mode they are more natural. Obviously not practical for ballscrews, so you need to change a 'tick' to a 'cross' on the...

PM the new setup should just move with the older settings file, just not the right speed or distance. Nothing has changed electronically between Mach3 and the 2000LE controller, but you now need a...

On a big machine I would agree, but I've never got around to fitting them on the Taig. It just stalls when you hit the end stop, and comes out of the nut if you go too far the other way.
Yes it can...

You have it ... Taig follow the same format ...

While the original thread is from 2011, I would be interested to know if the files are still available somewhere today as the subject is very much relevant to today since the original official boards...

The only think that has not been pointed out so far is that the DSLS3000 is only available as a full package since the controller and stepper motors are a Taig/Microproto proprietary design. It does...

Manual control over jogging is on of the problems many of my clients bring up, but one trick is to add a stand alone numeric pad keyboard which can sit next to the machine and you quickly get used to...

The quick answer is 'no'. You will need to make up an adapter lead to only use the available Parallel Port ins and outs. You quite rightly say pin 25 does not match, and I've used the same trick...

That is what I ended up doing with the train wheel. I needed the construction lines as well as the surfaces and that is what is missing from the STL model. FreeCAD is a little heavy going, but I'm...

Michael ... Not sure just what options are available in Aspire itself, but the main problem here is that there are no surfaces to take the frame from. I had a similar problem a few years back when...

The CNC ready machines are shipped with handles on the same as the Manual machine? At least the ones that land here.
I've replaced the plastic tube coupling with a more stable oldham coupling to...

It's worth a few more pointers here ...
The Taig mill is as has been said ... available with short or long table, but that is essentially the only mechanical difference these days. The manual...
