At line 540 you had a GO (like let's "GO") not G0.... Appears to call subs OK in my backplotter (NC Plot).

See attached....

Just some tips, ALWAYS use lower case o for the Sub name(o123) once you use it it comes obvious as to why

Either use cap G or lower G but not both

You cannot use  Z-#var  MACH3 will error you must solve the #val as a neg value  such as Z [-1*#3]  YES it does not comform to standard Gcode BUT that is just the way Mach3 does it.  The Z- in this case should indicate a neg DIRECTION call but it does not(;-)

Double check for end brackets on comments

Limit Comments to criticle issues  (;-) Gcode is not a diary. Makes it hard to follow with all the comments jumbling up the code AS mach3 does NOT handle comments correctly for display. It should maintain the Gcode line to comment relationship BUT it just zipps to the end of the comments and stays there.

Correct the notes in the returned file (notes are in the file)  and it should run ok.

(;-) TP

Thanks chaps-- this is really helping me

762X51  - please tell me how put the line numbers in ?? and formatted all to uppercase??
What is a back plotter ?



And TP - many thanks for the coding tips-- Certain conventions  always to the benefit of the
greater good.

Re z-#3 -- point noted

could it be done as
#3=-18

subroutine starts

go z#3 
??
thanks


So looks like all minor case at all times may be a good habit to develop ? also no comments on blank lines

Commenting kept to a minimum (as soon as I have memorised all the codes)

I have made the changes and it runs right throug- now just to debug and i can do my first job.

Fred,

I use NC Plot http://www.ncplot.com/ (http://www.ncplot.com/) and you can format your Gcode as well as display a plot of the tool paths with the program.

Attached is a screen shot...

good. they are punting their product called gwizard .

Hi Fred,

Yes, Gwizard is a nice program but I didn't like having to buy a "subscription" that has an ongoing annual cost.
