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.

General Mach Discussion / Re: How do I home the ATC

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 :

Hi Roy,

Taking a quick look at your .xml did not reveal a major problem although your motor tuning (velocity and acceleration) does look a bit strange.

Perhaps best to create a new profile and .xml file from scratch (just using the data from your old .xml) that way you will be certain of a non-corrupted file.

EDIT;  forgot to mention MDI does not work for me either when using your .xml

Hi Malcolm,

Something strange here...
Can you attach the .xml file that you are currently using (<profile>.xml) - the one you have attached has no ports and pins configuration.

General Mach Discussion / Re: How do I home the ATC

« on: February 25, 2017, 07:43:01 AM »

There is more than one way but I would write a VB (Cypress Enable) routine which basically does the following…

Check the home switch and if activated then exit if not then index ATC.
Repeat the operation.

The routine could then be placed in a Macro and called from within Gcode and / or placed in a screen button and executed upon button click.
