you are going to have this when you go small with lcam until they fix it. this is the way i would do this project with lcam. scale the drawing up in lcam 10 to 1 set your tool to .100 generate your code. set scale for mach X and Y axis from 1.000 to .100  put in your .010 cutter and let her rip.

Almaz did the dxf,i just filtered it to show him that he is doing something with his cad that lcam can't work with.but i will take a guess and say they are for thru holes and solder control.

Hey,Almaz

check your dxf export setting,and make sure you are using standard dxf-12 -- i did a import and then a export to dxf-12 and made you a lcam file.is this what it is suppose to look like.

i looked deeper at your drawing .i zoomed in on the junction points without using clean and optimize first.when lcam joins these points you will be left with bumps in the road.you have to figure out
if the cad is doing this or you are.

i forgot to add this.when a tool goes around a junction point doing a outside offset it has to hold the cutting edge to that point.the center of the tool has to have it's own arc path to
do this.lcam will add a entity for this.

some of us started working with lcam from the first ver until now.it has always been a beta program.there is no instruction manual that has any real value.but for the price it has power.
after some user time it will get smoother for you.lcam is just a raw tool.you will also find that how you use your cad will change.

EXTRA ENTITIES: this is a cad thing.lcam sees the junction point that your cad created.if you did the same drawing longhand with g-code,the junction points would be perfect,and lcam
will act accordingly.when you do a offset lcam adds a entity to go around that trashy junction.the next drawing you do ,try a greater scale say 4 to 1, then scale to size with lcam.small arcs
generated with a cad can sometimes be trouble with lcam.

is this what you are after,attached is a lcam file.the offset is done with a .250 tool clockwise.your original layer is still there but has been set disabled.when i imported your dxf my connection line tolerance is set to
.001 -- i am using lcam ver 3.00.2

double click your direction arrow,and a dialoge box will open,set it to auto.

you can make a new mill profile,copy from original,swap Y axis for A axis in ports and pins.move your motor tuning for Y axis to A axis and set as linear.take A axis motor tuning steps per degree
times 360 divide by 3.14 will give you steps per inch and set your new Y axis.

endo
when i looked at your tap file and did the numbers the .004 is not written in the file. so it must be a mechanical problem. check your table ways for slop.
something must be moving around.
