Just a quick note about USB:

USB is a very capable standard (127 devices per host controller), so there's no device issues related to multiple devices on one host controller, but still it would be best to not attach devices with high bandwidth needs (ie- USB external hard drive, USB audio or video device, etc.) while machining even though USB bandwidth is very good in USB 2.0. Other than that cable runs are 6' though with an active line amplifier/booster 20' is possible.

Featurewise, a downside compared to LAN is no wireless. Another, is of course, the short cable runs. LAN is better and the motion-control industry has choosen it over RS-232/422 which is quickly becoming legacy.

USB will go wireless soon though, it'll be called USB-IF and you can read more about it here: http://www.usb.org/developers/wusb

General Mach Discussion / Re: How do I zero Machine Coords for "A-axis"?

« on: January 04, 2008, 08:11:59 PM »

Thanks for that, but ref'ing A works fine for it's intended purpose.  I want to "zero" A machine coords without any motion.

My original question:

On the "Settings" tab in Mach3 there's an "Encoder Position" box with "Load DRO", "To DRO", and "Zero" buttons for X, Y, and Z...
These buttons also allow zeroing of "Machine Coords"... How do I zero Machine Coords for "A" in the same manner (without any machine motion)?

I hope the added clarity helps. Thanks!!!

Yes.  XY and Z will zero machine coords when "Encoder Position" box with "Load DRO", "To DRO", and "Zero" button are utilized.  I need to do same with A... how do I do that?

Thanks!!

Nope. still not zero'd, that only zero's it when not on machine coords.

Hi All,

On the "Settings" tab in Mach3 there's an "Encoder Position" box with "Load DRO", "To DRO", and "Zero" buttons for X, Y, and Z...

These buttons also allow zeroing of "Machine Coords"... How do I zero Machine Coords for "A"?

I've tried a few SetOEMDRO() parameters, but without any luck.  Any help is deeply appreciated.  Thanks!

General Mach Discussion / How do I reset to 0 degrees 4th axis without unwinding?

« on: December 28, 2007, 04:41:10 PM »

Hello Forum,

I have a to repeat a process several times that involves my 4th (or A) axis.  What's the best/easiest way to reset to 0 degrees 4th axis without unwinding between operations?

Also, can that be automated to run from gCode?  Thanks!

Hi Art,

What's causing the Z-Level "stair stepping" in the scans?  Is there a fix or setting that I can implement to minimize this adverse affect?

I have the same problem, I seem to get really great scans except for the "stair stepping.  When I build meshes and surfaces I have a lot of averaging and smoothing to do to get a good result to go to CAM with.

Thanks in advance.

Where does one find the new plugin???  I've installed the one at the Artsoft Download page but the installed version number "2.69" is unchanged.
