Thread: Fusion 360, Mach4 and first test of cnc router
21/01/2021 09:46:03

morning Steve you need a g54 command for the machine to know where you part is on the table dont no what would happen if you omit it it might use the machine zero the whole idea of g54 g55 g56 g57 g58 g59 offsets is you can have six different parts on the table say you have two vices on the machine machine first side g54 flip over in other vice g55 to machine other side

fusion should give a g54 code i also use cambam to produce my code i have to manually enter g54 and g43 i could alter some of the setting i think bot not that clever if it works dont fix it glad you have now cut your part

Hi Martin yes you are right been into the workshop my bench top mill has an option to inhibit z very small and hard to see to the right of the reset button

cant find it on my tormach screen totally different screen but do find more user friendly

Geoff

Jason beat me to it cnc is a great tool but can be very dangerous stay safe turn feed rates down on first run you have time to stop

Geoff

Steve i would put g54 on its on line then g0x0y0# z5# g1f300z1# if you want the machine to go to zero before cutting in my opinion a move not needed if you have a g0 command before its going to rapid all three axis. if z0 is top of work it could hit the work if setting are not right if you are a beginner this can be frighting it all happens so fast before you hit the panic button me personally i rapid to 5mm above the work as most my work is one offs it saves a lot of scrap parts

i am sure mach3 has function to stop z moves it used to be called dry run or set zero well above the work

Geoff

hi Steve had a closer look at your code this morning are you using mach3 post processor there some errors as i said before h0 needs a g43 command you are using tool1 so the command needs to be g43 h1 if you are using multiple tools the machine needs to know the length difference of each tool and entered into the offset page

there is no g54 command mach3 needs this to know where your part is on the table in xy and z

m26 at the end of the prog mach does not have that code looked it up tool unclamp ?

when i use fusion i get g28 codes at being and end of prog and tool changes this takes the machine back to the machine home position it does need more code to work if you look at Jasons code you can this

if you look at Jasons code for his g2 and g3 its incremental g91.1

g71 metric in your code g21 metric in Jasons

so there are a lot of differences between the to two programs makes me think your using the wrong the wrong p.p

spent many years programming cnc by hand
