DDSCV1.1 3 and 4 axis offline motion controller

[Boyan Silyavski]

My question does not concern the subordinate axis.
The question of correcting the perpendicularity of the axes.
For example, in Mach3, this is solved through formulas.

Ok i see. I did not even know it existed in Mach3.

Answer is No. But any software can do this. So it could be corrected in CAD.

if we are talking DIY CNC here, if its correctly constructed that will not be an issue. Epoxy leveling or surfacing. Mounting one rail against straight edge. With the help of same long straight edge and 2 precision squares mounting the second rail. If care is taken straightness and parallelism less than 0.05-0.02mm could be achieved even in a big router, which is absolutely enough. I have mounted 1000x500 machine with even better precision.

At the end of the day its a cheap controller. But as i said you can skew the drawing in any CAD then send it to CAM and machine.
