Hi zoheirlabibes,

You could either run in Exact Stop mode (Config / General Config - Motion Mode - select Exact Stop)

or...

Increase your Acceleration Rates in Motor Tuning (Config / Motor Tuning) for either or both the X and Y axes (you may also have to reduce the Velocity settings as well).

Obtaining the best results can be pretty much a matter of getting the balance between Velocity and Acceleration just right.

Tweakie.
PEACE

it works

but constant velocity seems to be smoother, especially for plasma cutting i believe.

balance between Velocity and Acceleration, tomorrow i'll test it in real conditions on the machine.
thanks

Hi Everyone

I still have a problem with .DXF files I have a simple block with my last name (Stewart) in lcam when I convert to mach3 all I see is 3/4 of the last letter(T), but not the block or name.  Again do I need to be licenced for both mach3 & Lcam?

Hey Jim,
  Post the dxf file you are using, Or, are you just doing the TEXT within LCam ?
Be aware of where you have the ORIGIN for your part.

I have used BobCad ver. 24 to draw a signboard with my name "Stewart" then saved to bobcad as a .dxf file.  When I open it in Lcam it only shows the outer edges of the board.
