Modbus / Re: Problem with Test Modbus Function

« on: May 02, 2014, 11:19:01 PM »

Hi,

When, you write to any of the config registers, you can only write to a single register at a time. if you try to write to multiple config registers in a single write command, you will get a timeout.

Also once you write to a config register, you need to reset the ModIO to take effect.

Cheers,

Peter

Hi,

In the spindle setup tab, there are delays for start up and shut down of the spindle. Try setting these to 0.

Cheers,

Modbus / Re: Problems with Modbus TCP

Hi,

The other problem you may be experiencing is that some USB to RS232 converters will fill their buffer, then transmit the data in a burst.

This can result in the Modbus inter- message gap being destroyed, resulting in CRC errors.

Hi Dan,

With John suggestion, the relay comes on when the Z goes negative.  It would be the simplest if you don't need to move the Z in the negative direction.

Hi,
It is fairly straight forward.

You could use the Gcode M words, to turn on and another to turn off an output.  You could select the user M words, say M800 and  M801 and write the scripts to activate the output.

The easier solution is to use the coolant control M word. Go into the spindle setup tab and set the output to be controlled by the coolant control.
Then to turn it on you can use M7 and to turn it ff M9. That way you won't need to write the macros.

Cheers,

Peter

If the VFD provides 10V, then use that. You will only loose a few % of the top speed.

Do you have the optional DC/DC converter plugged into the DC-03?

You also need to go into the Mach3 motor axis tuning tab and set an acceleration value for the spindle axis.

Drew,

I guess your the Andrew that sent me an email earlier today?

Please be kind enough to point out which parts of the manual are Ingrish and where the contradictions are and I'll attend to them. Or is that just your way of asking for help?

Presumably you've set up the Smoothstepper to produce the PWM signal?

Also, the SmoothStepper requires you to set an acceleration value for the spindle axis.

Hi,

If you are following the Article I wrote, you should be able to get it to work using the attached Brains.
