General Mach Discussion / Re: Laser pointers to set starting mill position
« on: December 06, 2009, 10:25:55 PM »
I bought this laser edge finder:

It serves my needs perfectly. I'm using it to index off a known point on a work piece I need to duplicate. I find it exceptionally handy for previewing the tool path of a program before I run it, and for measuring positions with the DRO. Thanks for the referral.

Google returns no links for "Zarzul".

General Mach Discussion / Where can I learn about macros?
« on: November 28, 2009, 04:22:43 PM »
The downloaded Mach3 instructions say:

    The Operator>Macros menu item displays a dialog which allows you to see the currently
    installed macros, to Load, Edit and Save or Save As the text.

But I find no such menu item under Operator.
Where can I learn about macros, how to use them, and how to write them?

My work mostly consists of milling operations on plastic materials. I need to index off a corner of a new piece, and the corner is often a raised edge inside the mill vice, too low for a wiggler. My accuracy requirements are modest. But the laser seems to offer something unique ... the ability to run through a program and verify the cut path on the workpiece. This would be a huge asset to me.

Are there inexpensive laser pointers available to chuck in the mill spindle and point me to a reference point on a work piece? Most common laser pointers are too bright and the spot is too big to set the origin. I built one once out of a "bullet" laser pointer but it was short lived and it seems like there ought to be a commercial one. I have seen expensive optical finders. There must be lower cost options these days.

General Mach Discussion / Re: How to install Shuttle Pro?

I'm new to Mach3 and had no idea there were other choices for a pendant. I got the ShuttlePro because I saw one at a friend's house. But then I suppose it might have taken me a long time to learn about the alternatives had I not asked questions about the one I bought. The USB interface works for me as I have only one parallel port. It's tempting to build a custom gizmo, but it quickly becomes a question of whether I want to build tools or use them. Time is short (and getting shorter).

Sorry to have wasted your time. You were right. Removing the installed driver makes it work fine. It's really a very handy pendant. You ought to try it.

Thanks for your help and your patience.

That's a start, thanks. I have enabled the ShuttlePro from "Config Plugins" but the system seems to have acquired molasses. Operation is sluggish and the ShuttlePro is slow to respond. After I release the jog wheel it continues to feed motion commands to the mill for several seconds because they sem to have "backed up" in a queue. I did NOT uninstall the ShuttlePro driver from their CD. Does someone have personal experience with this accessory?

I have received a Shuttle Pro and installed in on the PC but can't find any instructions in the Mach3 literature for how to make it available to the program.

I'm using Parker Hannifin OEM 650s matched properly to the motor current as best as I can tell, though the motors never get more than warm to the touch. The drivers do power down at idle, so it's hard to judge drive power from motor temperature.

I find that, when milling a 1 inch hole, I get a lot of jitter in the X axis unless I feed slower than 10 ipm.
