Writing offsets and reading coordinates in DNC mode?

[josh591]

I'm new to G-code programming.

My questions are:
1) Can I write offsets to the machine memory using DNC? If so, what is the g-code command? For example, can I do the equivalent of G54(x)=1.23 G54(y)=1.52 G54(z)=1.72?

2) Can I read positions in using g-code? Like can I query the machine what is xyz using DNC? If so, how?

Thanks in advance for the answers!

You can write offsets using the G10 command; have a look in the Haas manual.

G10 L12 G90 P1 R.5 will write the absolut value of 0.5 in to the tool comp table for tool 1.

G10 L2 G90 P1 X-5. Y-4. Z-6. will write -5. for the X coordinate, -4. for the Y coordinate and -6. for the Z coordinate into the G54 line for the work offset table.

As I suggest read the manual, it is a bit fuzzy at first but gradually gets clear.
