General Mach Discussion / Re: X-Axis rotation

« on: December 05, 2011, 08:05:28 AM »

I probably don't understand your question but I regularly use a rotary (A) Axis mounted to rotate either the X Axis or the Y Axis depending on the raster scan of the work (left to right or top to bottom of the image).

Perhaps you need to provide more details of what you need to achieve.

Hi Dave,

I am not aware of anyone using these analogue type of sensors (they are usually binary) so you may be pioneering new ground here. Interesting devices nonetheless and I would be most interested in hearing how you proceed.

General Mach Discussion / Re: Question about possible mach 3 project machine?

Hi Suade907,

Not quite sure why you haven't had other reply's to your post but, in my opinion, yes Mach can handle a 2 axis machine and as many switches and motors as you need. There are limits to the number of inputs and outputs from one LPT port but a second port (depending on your PC) can usually always be added. There are also a number of external motion controller cards with extended input / output capability it is just a matter of determining your projected needs.

Just a note Guys,

Do not fit a large capacitor across the output of a switched mode power supply it affects the sense response.

Hi John,

Perhaps a look through the lazy cam manual http://www.machsupport.com/forum/index.php/topic,12078.0.html may be helpful (I seldom use lazy cam so am no expert here).

General Mach Discussion / Re: Home Switch Staying Active

Jake,

You say that your switches are wired in parallel and set in Mach as active low. If that is the case then check your 5 volt pull-up resistor.

Hi John,

If you are using the demo (unlicensed) version of Mach there is a 500 line limit on the code. There are some code examples you can use for testing purposes here http://www.machsupport.com/forum/index.php/topic,18345.0.html
