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

« on: November 04, 2019, 12:54:58 AM »

hi
i have question about the mach acl/dcll manage
when i have one line  ,its simple
but when i have several lines or arc ,how the mach manage the acc dccl?
is sit calculate per segment? or as one long line ?(so only acc dcll at 2 side start,end)
or its deepened on segments length?
i mean without any link to CV wizard ,
thanks

before i use mach ,i use to use TPA ,its Italy controller ,then we had a lot of trouble
now when i use mach with pokeys ,i dont have any prolem with the inverter
pokeys have separate  ground to connect the inverter as 0-10 v
maybe this also help to avoid noise come into the system

and simulation show  exactly what will happened in real work.
pleas check again yours new wizard ,the ide is very good , but its have some bugs after exit from corner

Mach4 General Discussion / check gcode file before run

« on: September 19, 2019, 08:51:45 PM »

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
thanks
