Is there a way to send a value from a gcode to pyvcp?
I know about M68 but it is limited to only 4 variables, is there any alternative?

M68 can use up to 64 variables by setting the "num_aio" parameter when motion is loaded.
( man motion )
( man motion )

Another option is to directly "setp" the value of hal pins (or signals with "sets") with custom M-codes.

not sure what do you mean, can you give an example how it is done?

Look at the M100 example here in the documentation.
linuxcnc.org/docs/html/gcode/m-code.html#mcode:m100-m199
That example uses M100PnQnn to set the value of two hal pins equal to n and nn.
