General Mach Discussion / Re: About the motors

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.

Are the motors stalling at any time (making a whining sound) ?

Perhaps check your machines mechanicals for slipping coupling, loose grubscrew, binding of axis or screws, etc.

If I input 0xC400 Mach3 doesn't like it.

From the info you have given that is the correct address to enter.

Try reducing the X axis and Y axis Velocity and Acceleration in Motor Tuning by 50% and save the changes for each axis.

Is the machine still producing the same error ?

G-Code, CAD, and CAM discussions / Re: G31 probing - can Z travel be limited

« on: February 02, 2017, 05:44:30 AM »

No, I don't think you can.
Because the axis decelerates to a stop after the touching point it overruns and the exact point of touch is obtained from reading Var(2002) and I am not aware of any way to do this within Gcode - thus the use of a macro.
