Take a screen of the part with the pocket operation open on the heights tab. You probably have the contour at the top of the pocket or the heights set incorrectly

Hopefully this is what you mean !

General Mach Discussion / Mach3 & Fusion 360

« on: June 22, 2015, 11:35:35 AM »

Hi guys, I have recently been trying fusion 360, and am having problems with my first piece of code that fusion has written.
I drew a simple box with an odd shaped pocket inside it, made the pocket 20mm deep and asked fusion to cut down in 1mm increments using adaptive clearing. When I run the program it does everything as it should for the first 1mm, but then when it goes back to start the second cut, it just keeps spiraling down to 7mm !  Strange thing is, Mach 3 still reads the spindle as being at -2mm.
I`m not an expert with code, far from it, but I just can`t see why it should suddenly lose 5mm somewhere! Does anyone else have any experience in using fusion 360 with the generic mach3 mill pp ?

Ahhhhhhh, I`m not 100%, but I`m sure I`m using  R2.63 ??    does that sound about right?

FAQs / Threading Problems

« on: June 04, 2014, 08:11:13 AM »

Hey guys, another newbie question that has me stumped.
When using the threading wizard, no matter what length, size or pitch of thread , every 6th or 7th pass, it seems to take a real heavy cut !!!
For example, on a 20mm dia rod, cutting a 1mm pitch thread, and setting it to do 100 passes, every now and again the cut is so heavy that it will break the tip from the threading tool ( in stainless anyway)
Any help greatly appreciated. ;-)

Most likely the "I-J" mode is set incorrectly. It is located in the menu CONFIG>GENERAL CONFIG. I would recommend setting it in the code itself, and not the menu, with G90.1 or G91.1
If this does not fix your issue, attach the code in a reply and we will have a look.

You Sam, are a star    I done as you suggested and immediately, when I loaded the .nc file, all the circles were gone. I then clicked "start cycle" and it went on to do the whole job perfectly. God only knows how long it would have taken me to figure that out myself, so all I can say is --   many thanks my friend

This is what I was cutting.

Thanks Sam, this may be a bit beyond me, but I`ll certainly take a look tomorrow and report back

FAQs / Mach3 Going Crazy On Small Part

« on: February 17, 2014, 03:42:40 PM »

Hi guys, although not a total newbie with mach3, my knowledge is quite limited, and I have a problem I just can`t figure out.
I am trying to machine out a small (keyring size) set of knuckle dusters for a friend (he`s a streetfighter motorbike rider) and every time I load in the .nc file from cambam, all I get is lots of circles, with the actual toolpaths just visible in all the lines.
I am drawing the part in solidworks, then using cambam to generate the g code, and then importing to mach3.
I have in the past made lots of basic shaped parts, which all came out fine, but this is the smallest part I have done with so many cut-outs, and irregular shapes, can anyone suggest anything, it`s driving me crazy!
I might also just add that the cutter actually follows all the paths of the circles.

In these photos, you can just make out the parts that are "meant" to be cut out. I am using a 3mm cutter for these, so as to avoid overlapping paths.
