Wigit,
AWESOME.... wow it really looks smooth.... not sure what you will cut at 1000 IPM, but that is a fantastic rapid speed. CONGRATULATIONS!!!

good job, congrats

After I got the Constant Velocity settings in Mach3 correct, the rapids were even smoother !

Widget are you talking about that stutter when it changes from one are quadrant to another? If so my jonescnc is doing the same thing. how did you stop that stutter?

One of the settings in Mach3 is "Look Ahead", by default it's too low a number! Set it to 200 lines or more!

Nice Job Eric!
Another widgitmaster creation.
What's your first cut going to be?

Thanks Bill!

Only worked in the shop for a fey hours this afternoon, but I did get the Red & Green LED's to operate as needed!
I used an "Ice Cube" relay & socket, it is a triple pole double throw switch with a 12-VDC coil.
Now when I press the
E-Stop button the green LED goes off, the VFD's contactor de-energizes, and the red LED goes on!

On commercial machines, after releasing the E-stop, another button press is usually required to restore power. You don't want things turning back on as soon as you release the E-Stop button.

I think most VFDs will require a new command when repowered after power being cut.

Widgit: Is it all wired such that the estop is normally closed? I.e. the normally closed estop switch keeps the vfd contractor open and if you have a wire break or switch failure it will result in estop mode?

Each E-Stop has two NC switch blocks, one goes to the breakout board, the other to the relay. The relay is then active, and the contactor is in a closed circuit. A power failure would open the contactor!
As of today, the VFD is not connected, as I've been a little gun-shy because of the poor Chinese manual. A friend & fellow Zoner will be by tomorrow to help me figure it all out and get it powered up! As for the re-energizing of the VFD after E-Stop, well I'm not sure ??

On mine, there is a setting that you can make to switch between "non resume" and "resume" power after an outage.

The safe one of course is "non resume"

Today I removed the Z-Slide, and setup the mill to drill two deep holes for the work light wires. Then I milled two pockets in the end of the z-slide, then drilled & tapped some M3 holes to attach the LED's! Then I setup the z-slide on it's back, so I could put an intersecting hole on the inner surface. This way the wires will be behind the spindle motor, and plugged into a small Delrin block ( not made yet)! After deburring all the sharp edges, I installed the LED's, and temporarily hooked up the 12-VDC.

Sorry, poor phrasing on my part, I did mean contactor closed (power flowing to vfd). The way you have it wired sounds perfect.

Can someone help me locate a current list of Mach3's OEM Trigger codes, I could not locate them on the ArtSsoft pages!
