Title: G 93 code
Post by: edcross on August 24, 2021, 09:18:19 AM

Attached is a file that i converted with a G93 converter program . It adds separate feed rates for the A axis, when i run it in Mach 4.2.0.4612 , the A axis runs at the file feed rate , not at a separate rate for "A" .Does something have to be changed in Mach 4  , for it to recognize G93 code??

    Thanks

... a stab in the dark here.... I notice that in your G code uses only the LF (line feed) character between blocks. There is no space character or CR (carriage return) between the numeric value for F and the following G code. This is normal for Linux text files but might be confusing the Mach4 G code parser. G93 requires a F code for EACH block and Mach4 might be considering all your G code moves as being in the same block.

I found that in the motor tuning , with a new profile created for wrapping , you have to increase the feed rate and accel rate for the A axis and then the A axis will work much fasted. I ran the example file and it cut correctly and much faster, it did not affect the normal feed rate .

    Thanks for all the reply's
