Dear all @ Mach 3 Forum,
i was successfully working with this software for some years now, but still there is one question that confuses me.
Because of my converting Process from a different CAD all Cirles will be converted into a pair of semicircles in G-Code.
These Semicircles are not round when milling.
The router is milling two ellipses for each semicircle instead, and of of course the milling Path stopp´s at the end of the first one, then starts to mill the second one and finally stops again were it has started.
I´ve checked a lot to see were this strange behaivior is produced.
The two ellipses has a perfect coincidence to each other and it´s starting point and End point is congruent as well.
All linear movements are really accurate and the repeat accuracy is better then 2/100 mm aprox.
The Router is Driven by AC Servo Motors and Drive Units by Sanyo and everything is made fom heavy steel.
The Velocity and Acceleration parameters of the two X and Y motors is set to equal values in Mach3.
Off Course the mechanical inviroment for the X and Y movement is identical.
A Change of the cutting pressure does not change the fact that the router is milling two elipses and not two semicirles instead.
The only reason I can imagine is that the pulses for driving the X and Y Servos are not send at the same time simultaneously to X and Y Servo Motors.
The servos are driven via the USB-Smooth Stepper, contains the latest software.
Have somebody heard of that the Smooth stepper produces this ?
What cou be wrong with my setup ?
I appreciate every reply
thank you for your ideas
