ah yes, i understand now the half radius thing, i read it before but it never really clicked in until now

i was assuming i was using inches with each of my codes, hence the 0.125 = 1/8 or 0.25 = 1/4, etc

im guessing there is a section in program to specify mm from cm to inches

so for example .. i assumed using a 0.5 (half inch)distance from an X plot to a Y plot, half of that radius would be 1/8 = 0.125

forgive me if im wrong, which im sure i am, couldnt you use a "X plot Y plot R 0.125" kind of code in this situation?

also, i really do apologise for all the questions, only way to learn is practice/ask ... but .. is the default measurements for Mach3 mm? or where can i see this / change the measurements to inchs

again, thanks again for the time and effort to post, dont mean to be a nusance to anyone, and it really is appreciated

Ty much

ah ic ic, i understand now, thanks very much for clairfying that

so im guessing, the particular curve im trying to achieve at that particular point on the knuckles, its gonna be impossible cause the curve is way below the minimum ratio limit


how come 1.5 radius is the smallest radius possible? would you use Lazycam to achieve smaller curves (radius) then 1.5 ?

Thanks again .. sorry for asking so many questions .. just find this interesting and wanna learn as much as i can during spare time

Thanks tho

hmm i kind of understand what you mean in theory but to do it im not quite sure

is there any chance you or someone could post 1 line of working code? once i see it in relation to this model, i should be able to figure it out


Below is a code i made with a circle curve, i figured it out fine but using the same method, dosnt seem to work, or im missing something

Thanks for any help, really is much appreciated

hey another question, and i did figure out how to create curves/circles with all of your help, thanks very much for that

but i have been trying a new project, Brass knuckles (not really gonna make them, just for practice since the whole area is very curvey)

what ive got done so far, is the basic, square outline .. but now when i got back to re-edit and make a curvey outline, i have errors

this is my code so far

G00 G90 X0 Y0
G00 Z 0.125 X4.5 Y-3
G01 Z-0.125 F10.
G01 Y-2.75
X 3.5
G03 X3.5 Y-2.5 R0.5  -- delete this if your going to try, but this is my first attempt at a curve on the Knucks, (dosnt work)
X 4.75
Y -1.25
X 3.75
Y -1
X 2.75
Y -0.625
X 1.75
Y -1.25
X 0.5
Y -2.5
X 1.5
Y -2.75
X 0.5
Y -3
X 4.5


when i insert the code, nothing at all comes up, but when i remove the 1 curve attempt line, the outline shows up fine, is the curve ratio im attempting to big for the small length? or is the curve to small in general?

any assistance to why this wont work or how my code is wrong would be greatly appreciated and an excellent increase in experience for myself

Thanks in advance

Thanks, i'll check those out and fix tha problem

1 more question for the night .. in the display box .. is there a way to zoom and and see the design better?

Thanks

Thanks for the post. i been practicing coding different shapes .. like pyramid type things, wrapping my mind around how to code stuff, below is a code i made for practice but i know parts are missing such as spindle speed, which direction of rotation, manual stop and a few others

What program is used for the cam thing? id be interested in checking it out

and welding is going pretty good, we finished up our Tig welding course, i got my lap and 1/4" thick mild steel root passes done in all positions, since i got finished ahead of everyone else, i was show how to use the pipe cutter to bevel off edges of schedule 80 pipe

was practicing Tig welding the roots of pipe in all positions (tacked the pipe in a fixed position) and welded all the way around, very nice penetration on the insides with no skipped edges, got my hot passes in but had trouble filling up with the 7018, need more practice at that, i know what the problem was tho, doing blueprinting now for a month then done, out working

but yeh, any information about the cam program would be greatly appreciated, and practice coded is below if you wanted to check it out for some constructive criticism

Thanks in advance for any help

im pretty sure my setup is a little wrong, i cannot seem to get this circle going .. any suggestions?

G3 X0 Y25 R50  = if i put this into the code, wheni load up the code, this line disappears, like theres an error type thing

hey back again

i seem to be havign some troubles making turns

is there any chance you or anyone, could describe right quickly how to make turns

such as a simple S, C, O or a U type turns?

would be greatly appreciated, Ty in advance for any assistance

Excellent , thanks very much for the post, very informative and im sure more then just myself will find it useful

was curious about a few things

"S8000 M3 M8 ( THIS WILL GIVE YOUR TOOL A SPEED, A DIRECTON OF ROTATION AND TURN COOLANT ON) "
how would you set the direction .. M3 ? would be counter / clockwise? (assuming 8000 is the speed and M8 would be coolant on (M9 coolant off))


"G00 Z 0.075 X1 Y-1( IN THIS LINE I WOULD STOP AT Z 5.0"
im guessing that instead of 0.075 i would used 5.0? or does it depend what type of measurement method i use (mm, cm, etc) or is mach3 specifically done using mm measurement?


"G01 Z-0.25 F10 (THIS LINE IS GOOD)"
what would F10 mean?



Again thanks very much for your time for explaining and posting, greatly appreciated and im sure more then just myself is benefitting from it

also curious if you noticed anything wrong with my practice code itself? Thanks again

finished my first practice code, just trying to wrap my mind around how to use x/y/z axis, here is the code

Next i wanna learn some circular coding and learn how to make code to perfect measurement/scale

Feel free to add some constructive criticism
