mach 3 scaling issue

[JAZZCNC]

See pic for scaling location.

To test if moving correct distance use the MDI and command a move. Try this.
First Zero the axis you wish to move. In this case lets say X axis. Type these commands in order written below push enter after each.

G21
G90
G1 X54 F500

If it doesn't move correct distance then it can only be that your Steps per are not set correctly.

It's very easy to calculate the steps per. Take the micro step setting on the drive and divide by the pitch of the ballscrew. If uses ratio this will need be taken into account.
