Starturn 4 '.sta" format

Glad you worked it out

Can you qoute a couple of examples of the string to number conversion so anyone else could do the same ?

I'm going to check with my friend that figured it out and if it's OK with him I'll post the reply I got from him. The data is(as I remember it):
79 bytes for each line of startuen data

byte 1 = line #
Byte 2 = ?
Byte 3 = 1 to indicate if the number in byte 4 is G, 2 if it is an M code
Byte 4 = value of G or M code
Byte 5 = # of valid characters in the remark statement to follow
Byte 6 to 37 = ascii text of remark statement
Byte 38 to 44 X value in mantissa/exponent format
Byte 45 to 51 Y value
Byte 52 to 58 F value
Byte 59 to 65 R value

That's about how it fell out. I hope it helps someone else.

And after all that ....... Mr Magoo finds a DOS utility which takes G-Code text files and creates an STA and a STS file

Here it is:

[robtjhill]

i have run in command prompt but, cannot read nc file is displayed where it should have converted blocks

can someone tell me what i am doing wrong

[Mr Magoo]

I've just seen this post - wish I'd seen it earlier to save you folks some pain.

The attached STSPEC.TXT gives the file format the txt file should follow in order for it to be read by the conversion program. HTH

Hi Karl...

I know it's a bit late in the day to post this, but here is the format of a Program Block record (cnc block) that is loaded / saved by the Starturn...

Code: Select all

blockno:    // looks like this is a 16 bit signed integer ??
kind:        // byte: 0=blank line, 1=GCode, 2=MCode, 3=comment
code:       // byte: G or M Code value
commentary: // comment text (first byte is text length),then 32 bytes 
parms: array [1 .. 6] of   // array of 6 parameters to follow (eg x, y, z, f, r )
  record               // (I guess a max of 6 because of a threading block)
    value: real;      // float: each parameters value
    filled: boolean   // boolean (probably a byte): true if this parameter is used?
  end

Hope this makes sense if you're pursuing you own file writer! I may be able to dig out some further notes if it helps.
