So, I got a nice new .125" ball nose end mill and set about running the Circular Pocket Wizard.
After making a few dimensional alterations to fit my stock and machine, I hit the "GO" button.
Things were progressing nicely on the initial pass until it reached approximately 3/4", and then things started getting weird.
You can see what happened in the pic.

Changes I made in the Wizard were: setting the tool diameter and stepover percentage, reducing the overall diameter of the pocket to 1.5", reducing the overall depth to .500", as well as feed rate.

I removed the end mill, homed the axes and hit the "GO" button again with essentially the same result cutting air.
The machine is a Dyna Myte 2400 using the OEM steppers and drivers through a SmoothStepper and a Probotix breakout board.

Anyone have any ideas on where to start trouble shooting?

Doh!!
Would you believe, X axis weirdness?


Rex

Yes, X axis is stalling, lower your accel and see if it helps. Also worth checking wiring connections just in case they are loose.

Hood,

Thanx for getting me squared away!

I decreased the acceleration of both the X and Y axes, made a couple of adjustments to the Wizard, and cut a very respectable circular pocket. 5 passes to reach a final depth of .300" and the Dyna never missed a step!


Rex

Glad you got it
