Electronics for New Machine + Chinese Spindle + VFD

Thanks Chaps.

Jazz I have home switches. Prox sensors.
UCCNC is very similar to Mach, just without so many bells and whistles.

In the past I have been plunging into my workpiece at Job 0,0 to make a point so if I lost position for what ever reason, i could manually by eye line up again.
Not very accurate and not very satisfactory.

Just reading the UCCNC manual and yes there is a way to save offsets, something I haven't ever really understood.
In fact its a single button press to "Offset Current Position". I will test, but I assume this saves the current position as a job Zero point relative to the machine co-ordinates.

One thing I was very happy with is that after two hours of running, the machine went back to the zero point and it looked exactly right.
The machine co-ordinates were also exactly as they were when I started. So accuracy is looking good.

I will at some point put a homing switch on my A axis as well to ensure my gantry is square.

One thing I have just decided is that there is no business in 3d machining wooden stuff. It takes so long!
I have been making a complex mirror frame and it has taken me all week. Each side of the frame took 3 hours machining.
Something tells me that 3d machining is also very hard on the machine as all 4 motors are working flat out for long periods.

Back to the drawing board on the business front.
Do either of you guys know of people making stuff and making it pay ?
I guess you have to find a niche.

Thanks
