Mach4 General Discussion / not stop spindle when press stop

« on: January 11, 2020, 05:01:46 AM »

i have now new machine configuration that the spindle dust cover (hood) move by servo motor
all work ok but have one point need
we have external button that when we press its should go up or down the hood
because its axis i saw that the only option is to write the script that ,stop the gcode  ,then move that hood axis's ,then continue the gcode
all this its ok for me  ,but problem its that i didn't see any option that avoid turn off spindle when i stop the gcode
i do have for hold but not for stop
any advice?

Mach4 General Discussion / S curve

« on: November 04, 2019, 01:17:00 AM »

we use the mach system in chines cnc
its work very good  ,and we improve ... so now i can say we almost can reach the Europa big brand(in wood cnc field)
but in one parameter i sill far back  ,it the acceleration deceleration while G1(working in the material)
if i try change to be close to that machines  ,i start get very bad working at the start ,end of working
so we add M function that change accl dccl in gcode ,so when move on G0 for example for drilling  ,we increase
...
but in G1 we need go very very low accll (les then 10000 mm/sec2)
as i try learn about that problem  ,i see that solution may be with the s curve
is some one meet that problem before? have an ide how mange it with mach4?
thanks
* i thought about simple solution that i can divice the movment in my pp and change acc dccl in the g code  ,but in this case  i can make it in some steps not smooth like s curve

i have reqwest from several clients that ask me to add script that will run over the gcode file before start ,and if there some dangerous steps(like z in minus more then....) will stop or give alarm...
is that can be done inside mach with lua ? or i must close the file load it on external app(like c#) check and then open again the file in mach if all ok
