Hello guys, I've just making initial cutting with my cnc, and facing this problems :
1) Examples like roadrunner, ball, etc, produce a very small figure. I had to scale axis in Mach3 up to 20 times to get a figure of 100mm wide.
3) I made motor tunning in MAch3, and finally set up 760 steps per unit, and 450 units/min max speed. This is 450 mm/min .
The problem is, when running a gcode, Mach3 run very slow the motors, feeding them at 4 units/min. I increase the FRO, but couldn't go higher than 12 units/min.
I cannot push the axes at a reasonably speed, and testing motors in motor tunning can do it much more quickly.
Help PleasE!
