I will try that when I get a chance.  I am a little confused about how that works but am willing to give it a try.

Thanks!

Nick,

I understand what you are saying about setting the diameter.  But if the feed rate is set to 50 units per minute or similar that is still really slow for the rotary axis.  What is the steps per uit on your setup?

Thanks!

I have been using the one from Bob Campbell Designs.  Have about 5 of them.  They are really good boards and easy to use.  They have mounting holes for easy installation.  They come with a ribbon cable to plug your parallel port into and have screw terminals to connect your step, direction and limit switches to.  Very nice boards....

General Mach Discussion / rotary axis turning really really slow

« on: January 13, 2008, 08:20:12 PM »

I have built and installed a 4th axis on my machine.  I have seen several posts regarding this but have not discovered a solution to my problem.
My "A" axis is set to 22.222 steps per, 10002 as the velocity and 1700 as the acceleration.

The problem is that when you are doing a move that uses one of the linear axis, say the "Y", and the "A", the feed rate may be 35 ipm or similar.  It takes forever for the rotary axis to move to the desired position based on that feedrate.  How do you deal with this big difference?

Can someone help me out?

General Mach Discussion / Griffin PowerMate

« on: December 30, 2007, 09:24:12 PM »

I just purchased one of the Griffin PowerMates.  I downloaded the plugin.  Since I am kind of new to this I have a couple of questions.  Do I need to install the PowerMate software and configure anything for Mach3?

When I press the top of the device it toggles between the available axis but nothing happens when I turn the knob.

Am I missing something?

Thanks!

General Mach Discussion / Wierd color on Settings screen

« on: December 11, 2007, 11:03:01 AM »

I installed Mach3 and on the "Settings" screen the background is green.  All the other screens are grey.

How can I change that or is my 1024.set bad?

Thanks!
