The 4 input terminals on the G540 are connected to an internal 12V supply by an internal pullup resistors.

The switches in the circuit above as normally open. When the switch is activated, it connects the input to ground, activating Mach3.

Hi,

Your problem will be mid-band resonance. It occurs at low speed in the range of 2-6rps. You can hear the motors growl and change pitch when it is occuring.

What you need to do is buy a decent stepper drive such as the Gecko G540 4-axis stepper system that I sell. You won't look back.

General Mach Discussion / Re: Licensing MACH3 for a Tormach 1100 mill

Hi Cliff,

When you order a licence, you should receive an email that includes a licence file called license.dat. It will be in an attachment to the email. You need to extract it from the zip file and place it in the Mach3 directory.
Then when you start up Mach3, it will load the licence file. If you look at the help->about dialog , it will have your name there.

Check if it has ended up in your spam folder. If it's not there, contact the Mach3 support and they should be able to help you out.

They are not really necessary as most bobs accept 3.3v level signals

General Mach Discussion / Re: Kernel speed change
« on: January 01, 2016, 07:46:15 PM »
The steps/per is the same, but the velocity and acceleration will change. This is because they are stored in iterations of the kernel rate.
For instance, a velocity of 1 step every 1000 kernel iterations will be a different velocity when the kernel rate is 45KHz as compared to 25KHz.

Also the debounce  period will be a lot shorter if you increase the kernel speed. That possibly may be the reason for the estop durring a cutting operation.

Ok thanks

but the overall effect of steps per and acceleration / speed should remain the same no?

Hi,

When you change the kernel speed you will need to retune the velocity and acceleration of each axis. You may just need to go into the tuning table and resave the settings for each axis.

Also if you are using the debounce function you may need to increase the count if you increase the kernel speed as the debounce value is the number olof kernel ticks that the debounce lasts for.

Cheers,

Peter

Have you enabled the spindle with an M3 command? The speed is only  shown if the spindle has been turned on in Mach3.

SmoothStepper USB / Re: USB_SS and digital I/O

The PWM output works fine on the SmoothStepper.

You need to set it up it the SmoothStepper Config tab, not the Poerts and pins config tab.

Also you need to ensure that you set an acceleration  value for the spindle axis in the motor tuning tab.

Cheers,

Peter
