Help needed v carve to mach3
« on: September 16, 2016, 03:42:03 PM »
Hi chaps.I have a problem.my mill cuts find.on checking the movement of the tool using test g code and also the mach software,all is ok. The mill is set for mm. I made a simple square design using v carve.but when using the g code.the mill cuts far to large.both the mill and the g code is set to mm.
Can anyone help me out here.

how much too big? like 10 times?

I suppose you have tuned your machine?

Hi.yes the machine is tuned. Parts come out around 150% larger

is it all the same for all axis?

I am asking because I get confused sometimes, it goes like this

open your tape measure and pull it out for 1/2 a meter and it says 50 but its not 50mm its 500mm,

my guts say check your dimensions in the drawing programme

Another thought is; what post processor are you using in Vcarve?

hi, I posted the code using Mach2/3 ATC Arcs (mm)(*txt)       I have know idea what is going wrong here.

The answer is right in the g-code. Is the code it producing the same size as the part you drew? Have you put a tool diameter in v-carve and are you cutting inside or outside of a profile?

h. I ran the g code in an editor before posting to the machine. the cuts are inside and yes I did input tool diameter into vcarve. could it be the way that mach is reading the g code ????

your not giving enough info for us to make any judgement!!!!

Saying it doesnt work is not enough!

Please tell us in detail what calibrating you have done. :)

have you looked at utube for help?

try looking at this video please https://www.youtube.com/watch?v=LRagjLewSJg

sorry if I come across strongly but unless we have decent info we are just guessing

Hi. I have used the mach 3 software to scale the stepper motors, and they move the correct distance on each axis. I have reduced the motor accelerate, I have checked that the mach 3 is in the mm setting.i have made sure that the correct ccutting tool dimensions are bring used.
I have used the road runner demo and it cuts correctly. But when I try to cut with the vcarve g code, the machine trys to cut to large a work and I need to end the process as the machine runs off the bed.
I have ulso used Cam editor to read the g code produced by vcarve and the diameters come out correctly.
And you are not coming on to strong, I am glad of the help.
