Electronics for New Machine + Chinese Spindle + VFD

[JAZZCNC]

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.

Yes I know that's why I said it. I do have UCCNC but don't use it. Mainly because there boards are USB not because the software isn't any good. It's Ok software but a little basic for me.

OFFSET's are easy really.! You just have to get your head around the fact you have 2 Coordinate systems. MACHINE & WORK.
WORK coordinates are variable and you can define ZERO anywhere on your machine bed.
MACHINE coordinates are FIXED and never change. Only way they can change is you move the HOME Switch.

WORK ZERO or correctly termed WORK OFFSET is just an OFFSET distance from the FIXED Machine ZERO Position. Save this OFFSET distance and you can always accurately get back into position by Homing the Machine and then sending to WORK ZERO.

Now where it can get a little Tricky is the Fact you can have Multiple WORK OFFSETS each having it's own unique ZERO Position. This is done using Special OFFSET G-codes G54, G55, G56 etc upto the limit of the controller.
By default you are proably using G54 so never really are aware of the fact and by default your CAM software will be using G54 offset.

But lets say you wanted to cut 3 different jobs in 3 differant materials using same tool. First place each material on the bed and define Zero and save the offset for that material using one of the WORK OFFSET's codes.
Then what you can do is produce individual G-code for each part. Then copy & paste into one Large file. At the start of each Job you enter the OFFSET code you have setup in advance. ie job #1=G54 #2=G55 #3=G56

Now when the code runs after first job it goes to next WORK OFFSET and starts again from the new Zero.

Try it using the MDI. First go to OFFSETs and enter different values in G54 and G55. Make sure machine is away from any of the coordinates you typed. Now Enter G54 G0 X0Y0 and it should go to that posiiton and DRO's will display ZERO's. Now type G55 G0X0 Y0 and it go to that position and the DRO's will read Zero's.!

Do either of you guys know of people making stuff and making it pay ?
I guess you have to find a niche.

Yes I know many but Can't tell you what they do because of client confidentiality.!!. . . . . Well I could but then I'd have to Elimnate you.!! . .
Your right thou most are Niche markets and they earn well from them.!
