Mach3 under Vista / Re: Mach3 Axis Calibration Mystery

« on: February 28, 2017, 10:21:06 AM »

However, when i click the GO TO ZERO, the X-axis is moving to its ZERO at a far higher speed than I can obtain by the motor tuning without the motor stalling? What is the explanation for that? Of course if I could imitate the tuning that the Mach3 is using for the GO TO ZERO command, then I'd be much better off speedwise...

Hi Anders,

I have no explanation for that but remember that accuracy and reliability is far more important than speed so don't go setting your Velocity too high.

Check your TB6600 drivers, they may be set to ½ step.

(200*2) / 116.18 =  3.443

Hi Malcolm,

You need to post the .xml file that you are using. It is in your Mach3 folder and it is called <your profile>.xml

Roman numeral 4 is represented as "IV" not "IIII"

True - but on clockfaces it is often not the case. http://www.web40571.clarahost.co.uk/roman/clockface.htm

Can you tell us the make / model of the breakout board and the motor drivers you are using ?

Hi Malcolm,

Assuming you are indeed using the parallel port to drive your CNC machine then you will need to configure the Ports and Pins in Motor Outputs and insure there are no pin number conflicts in Output Signals etc.

This is a screen shot from the last .xml file you posted.

Hi Anders,

Obviously your drives microstepping is set to 1/8 which is just fine.
You are very unlikely to achieve any higher resolution or performance if you change microstepping to 1/16 so it would be better to leave it as it is.

I assume your switches are normally closed circuit (n.c.) connected in series. With everything switched off, use a multimeter (on continuity) at the breakout board to test your switch wires which should show closed circuit - operating any switch should show open circuit. If this is not the case then you may have made a mistake in your wiring of the extended switch.

Got it! turns out the roadrunner gcode is made really small.

Not quite.

The Roadrunner Gcode produces a product that is approx. 7 1/2 inches by 6 1/2 inches.

Try some of the Gcode files from the .zip folder here : http://www.machsupport.com/forum/index.php/topic,18345.msg126486.html#msg126486 they should come out correct size as I have included the G20 / G21 (as appropriate) so they work just the same with machines that have been set-up in Metric or Imperial units.

Hi Gaute,

The code required is Cypress Enable, which is a variation of VB so you need to make some alterations to your proposed code for it to work.
The Mach3 Scripter  (Operator / VB Script Editor) should help you compile suitable code and hopefully it will flag any errors etc.

The following documents may be of assistance to you :
