Hello

just change the tool number in the second MOP, if the tool number change between 2 mop, CB will write a toolchange in the Gcode even if tool diameter/profile is the same for both MOP

If you use tool library, before to change the tool number, first set tool diameter and tool profile to "value" in the second MOP so this values will not be changed when you change the toolnumber.

It's something I use sometimes.

Hello

A link to the V1.0 R15 that have the export STL built-in

http://www.cambam.co.uk/downloads/dw/CamBamPlus-1.0-alpha15.msi

note: if you use my Extrude Solids plugin, remove it, the R15 has the same function built-in (in the same menu)

Hello Steve

You can use this script to save stl.

http://www.cambam.co.uk/forum/index.php?action=dlattach;topic=2287.0;attach=20206

The very last version of CB 1.0 (R15) as a build in STL export option ... I think Andy will make it public soon.

Hello

Lol, or you can directly use the english page

Hello

Ok, good luck for the tests

The settings for Wrapper plugin and the transformed nc file (I do no change on your Cambam settings)

(Note: I use my own post pro, so infos for cutviewer are also included in the Gcode)

Hello

Some picture of Mach3 settings and Mach3 and NCplot simulation

Thanks again David, I don't understand how to share the cambam file with the MOP's on it

Just save your .cb file you have used to do your Gcode, and attach it to the message, it's the same as you do on reply #3, but in the file on reply #3 no machining operation is defined, it contain only the polylines.

I get the same as your picture, if "A rotation" is disabled in Config/toolpath

Re

I retrieve an old video here

https://www.youtube.com/edit?o=U&video_id=zH8miXGSdus

I guess that your problem is with stock surface, clearance plane and target depth values in the MOPs.

To wrap the drawing around a cylinder of 49.66mm Ø, you must set:

Stock surface = radius (24.83)
Clearance plane = above the radius .. i.e. = 30
Target depth = radius - pocket depth > so for a pocket = 2mm deep, 24.83-2 = 22.83

Hello

I can get wrapped toolpaths on Mach3 (pic1) with you file, but an error remain with Z position ; in the Gcode header I can see (JOB DIAMETER = 49.66), but in the code, all Z values are close to 0 or < to 0 (Z=0 is the rotation center of the 4th axis), and the max Z height is +1 (so IN the stock) ... for a part with this diameter, the Z value for an engraving job on a cylinder must be close to the radius value and the Z clearance must be > to the radius. I guess that you have a problem in your MOP settings or in CNC wrapper settings. (I don't use CNC Wrapper so I don't remember how it works, I use the Wrapper plugin)

my Mach3 settings are:

In config/toolpath:
  Axis of rotation > X axis
  A Rotation enabled > checked

In General config, rotational section > all three settings unchecked

I would be fine if you can also share the .cb file (the one in the previous message contain only a drawing, the pocket MOPs are missing)

PS: to use the internal wrapping system of the V1.0, you need to do some change in the PP, but currently the explanations are only in French ; I'll will translate them when time permit.  

[must not contain arcs]

Hello,

I just have a look on your Gcode and I can see that the file contain G2 (arcs)

The Gcode must not contain arcs (G2, G3), because arcs can't be wrapped ; the code must contain only G0 and G1 (strait moves)

To solve this pb, change the Options - Arc Output property of your post processor to convert to lines, so arcs will be automatically converted to a series of small lines.

++
David

Note: this is true for all wrapping methods (CNC Wrapper, Wrapper plugin)

If you're using the built-in wrapper method of CB 1.0 post pro, it is not necessary to set this property to convert to line, If Rotary Wrap is set to True, the post processor will convert all toolpaths to lines only, then wrap all the toolpaths selected around the rotary axis. (it use stock surface of the MOP as radius to wrap)

Salut,

je ne sais pas s'il existe des softs gratuits ; pour ma part, j'utilise NCplot (ce n'est pas de la 3D, çe ne trace que les parcours, et ce n'est pas gratuit)

Je ne connais pas Linux CNc, mais sur Mach3 on peut aussi visualiser des parcours 4 axes.

Hello,

Yes, a tuto exists, but only in French at the moment ... It remain to translate. (it's a good thing to remind me, I totally forgot this one)
