Xylotex 3 axis board set up

I have recently made the switch from Mach to EMC. I have a MiniMill X2 using a Xylotex 3 axis board. I have 425 oz steppers on the X and Y, and the 269 oz on the Z.

After much time spent in the Axis configuration I have set the values to the following:

Both X and Y
Steps per rev: 200
Microstepping: 8
Ratio: 1:1
Pitch: 16
Vmax: .5
Amax: 30

Z Axis
Steps per rev: 200
Microstepping: 8
Ratio: 1:1
Pitch: 5 (ballscrew)
Vmax: .3
Amax: 10


This seems to run just fine during the testing/configuring but when it comes to actual jogging around I am getting a bit of motor stuttering unless I am using the rapid jog. Furthermore, if I jog a few times in one direction, it occasionally jogs in the wrong direction - this really worries me!

I am really new at this and don't know were to begin troubleshooting this behavior. Thanks.

Hello,

You might try longer direction setup time and direction hold times in your hal file.

Thank you for the quick response!

Now I must figure out how to do this.....

Nevermind...

it is a blown board
