Hood,
The D05 does have Modbus, i believe it has an RJ12 plug, you can make a cable to RS232 and have serial modbus.

Podunk,
You will net to add an AND condition to be able to turn the output OFF with a button.

[Sipindle ON]------[No Op]--------|AND|__________[Output#4]
[Input#5]----------[No Op]--------|      |

Something like that, the output 4 will only be active when both spindle and output are active, if you turn either input off, Output 4 will turn off.

Hope that makes sense.

Show"N"Tell ( Your Machines) / Re: New Build 6 axis CNC first timer
« on: May 11, 2009, 11:31:50 AM »
Hello,
Well, actually no... Mach 3 cannot generate paths. It can with wizards generate 2D and 2.5D toolpaths, and with Lazycam too, but not 3d toolpaths certainly not 5 or 6 axis.
Mach 3 will do what you tell it to do, so you need a CAM package to do the toolpaths,
5 axis CAM packages are expensive since they need to calculate tool offsets in 5 axis, there are a few out there. A freeware cam plugin is available for 3DS MAX, GMAX and Autodesk VIZ, it is called CNC Toolkit
http://groups.yahoo.com/group/CNC_Toolkit/
It works but it has a steep learning curve but it does work.

Now Indexing vs continuous:
Indexing refers to having some axes still while machining with the remaining ones. One example would be a 4th axis rotary table. you machine with 3 axis while holding the rotary table still, then turn the rotary 90 degrees and then machine again in 3 axis, then turn it another 90 degrees and machine again etc..etc..
Continuous is when all axes are moving at the same time.

Now with your control box, heatsinks are a must if your steppers are above 3 amps i think, but it is a good idea to have them even if its under that. you have 5 geckos mounted on your box, and you say you still need to mount TWO geckos more? that would be 7 geckos, and mach can only handle 6 with dual parallel ports.

Be careful,
I read somewhere (might have been in the gecko manuals) that the DC side of a power supply should never have a switch of any kind, or it WILL damage your drives.

VB and the development of wizards / Re: Pause milling on G0
« on: April 27, 2009, 10:55:22 AM »
I would in this case, just enabled the Optional M1 Stop in the main screen, and would have added an M1 before each G0, that way the Gcode would feed hold until cycle start would be pressed again.

Do you have backlash compensation on?

If you dont have any noticable backlash, and you have the backlash compensation on, that would give you  the .75 instead of .5.

Another thing, that could give you that would be loosing steps, try lowering your acceleration and speed when tuning your motors.

Well first of all, you cant jog the machine while it is running a gcode file, if thats what you are doing, then it wont work.

If you are not jogging while running a gcode two things might be happening,
1. you have clicked inside the MDI line or any DRO, which would block the arrow keys from jogging until you get out of them.
2. there is a button called Jog off, under the Tool information part in the main screen. you can toggle it with Ctrl-Alt-J

Hope that helps

G53 will move the machine in absolute machine coordinates

Then you can go back to work coordinates with G90

so you would write a macro with something like this:

CODE ("G53")
CODE ("G00 z135")
CODE ("G90")
CODE ("G00 x0 y0")

That should take care of it.

Awesome Job, Great Finish too
