New Mill losing steps

[lukecnc2012]

Hi all.
Purchased a new mill to start small production prototypes and seems to be loosing steps In y axis.was only cutting model board at 1.5mm depth and 300 on feed rate.
Any advice How to prevent this much appreciated.

Need more info regarding make/model of machine.
Are you using Mach3 with it ? if so, what do you have the motor tunings set to ?

When you say mill are you meaning a router type machine ?

Numbers seems to be all over the place.

Is the motor layout like this ?
1 on Z axis
1 on Y axis
2 on X axis (X on one side and A on the other ?)

If they are then X and A should have the same settings for a start because they have to work in harmony, the velocity and acceleration on A are too high.
If the machine can't physically achieve the settings you've put it will loose steps

Only one motor on each axis the 4th axis is detachable.so currently of the machine.what sort of feed should be reasonable for this machine currently only running 200 mm pm
