Dear all,
I have a CNC machine with two Siemens Stepper Motors connected by two STEPDRIVE to the parallel port of a PC..
I am using Mach3, and Sheetcam (for converting from Autocad to G-code)..
When i have a straight lines drawing with any orientation, the motors go perfectly, even when increases the feed rate (Frequency of pulses)..
But when a curve or a circle is wanted to be drawn, the motors get stuck if i increases the feed rate little more !!!
Is it the code?
or What??
Any help plz??
Regards,
