how can i stop the machine in the middle of the movement?
let's say that i gave this command from script Code "G0 X500 " and now i want to stop the machine because the probe hit the object

if i make less cals to getOEMDRO(*********) it goes 2-2,5 faster

I think that the problem is somewhere around these specific commands and VB. The communication is not so fast. The best way is to store as much values as possible in variables, and only use special commands when needed.

I have achieved somewhere around 15 points per second at a precision of 0,03 mm, if i can double the speed is perfect

BR549, how to write the probing sequence in GCODE? (in Mach3) can you give me an example? i have tested the plug-in that creates GCODE for scanning, but is slower than my script, because it makes a lot of useless moves  ... (bed of nails?!)

ger21, i have increased the feedrate, but no luck. If i decrease the speed below a certain value, it slows down.


stirling, thank you for the explanation. I was thinking that Mach3 is "has the ability to "lookahead"" and that is why is much faster when cutting (but i wasn't sure).

I will experiment more and write down the conclusions here...

Hi, i have a 3d router and i have written a script for 3d digitizing, it works, but is very slow. My machines runs pretty fast when it cuts.

Maybe a better computer? but i am unable to understand why the speed of cutting is greater (10 times greater) on the same computer.
I have windows 7, 32 bit, 4 GB of ram, Intel core duo 2,56 Ghz. I use parallel port.

I Have tried to change kernel speed in mach3.
The script contains ~300 lines of code (including some comments).
The script compute the next move based on the state of touch probe (1 or 0) at the end of the anterior move.
All the coordinates are stored in some variables, and from time to time, are written to a file.

What do you think the problem is ? how can i increase the speed of a VB script execution?
