Obviously not all stepper motor controllers are the same but (having looked at your video) it would be unusual for a stepper motor to change it’s rotational direction whilst the controller is receiving a continuous stream of step pulses (this is determined by the set-up timing between step and direction pulses).
My guess is that your data communication between the PC and the controller is being interrupted. Probably the most common cause being bad wiring or bad plug / socket connections. Thoroughly check all your connections and wiring, including inside the control box itself (plenty of Chinese electronics comes complete with solder blobs and dry solder joints).

To use any of the optically isolated inputs (10 to 13) on the FP-48 they have to be provided with between +5 and +12 volts (+) connection and then they can be switched ON and OFF by taking the (-) connection to GND (active low signal to Mach3).

Connect your red wire to +12 volts then connect your black wire to GND and the FP-48 on-board IO LED should illuminate. You then need to set-up your probe operation.

Hi Mike,

Radius (R) is a Mach3 approved method - Newfangled Wizards use R for circular pocketing.

Can anybody here give me a definitive answer as to the correct wiring sequence?

Sorry for the confusion.

The definitive answer is shown in the Gecko documentation. If Gecko show EStop connected between Pin 10 and Pin 12 then that is the way you should connect it.

Generally, increase the Velocity until the motor stalls then reduce the Velocity by 30%. The Acceleration should initially be set at 10% of the Velocity figure.
After that 'trial and error' may be used for tuning to obtain best, reliable, performance.

The Mach3 manual (Section 5 and 5.5 in particular) details the setting-up procedure  http://www.machsupport.com/help-learning/product-manuals/

Mach4 General Discussion / Re: Parallel port not recommended???

You still need a motion controller (or the PP plugin) to operate your G540. 

Perhaps I didn't explain it correctly - I have both the PP plugin and the ESS and comparatively the ESS is better.

I have both the parallel port plugin and an ESS motion controller working with WinXP & Mach4. Overall, the performance is a lot better when using the ESS.
My recommendation - go for a motion controller.

Mach4 is quite heavy on graphics so try your integrated video but be prepared to add a graphics card if necessary.

Not sure that I understand completely but...

Mach3 needs to be installed on the PC's Hard Drive if you wish to use the parallel port. You can download Version 3.043.062 from the .ftp site here ftp://anonymous:guest@ftp.machsupport.com/Mach3/

Can you give us some more details about your machine...

What controller are you using ?
(a picture would be good)

So you have a 2:1 reduction geared X and Y axis (20t on motor and 40t on shaft) but what is the shaft ?

Please refer to Sections 5.4 / 5.5... of the Mach3 manual which details steps per unit calculation.
