1  Support / CamBam help (General usage) / Re: Edit post processor on: Today at 15:58:33
Hello,

To add the delay in the PP, go to the CamBam system tab, post processor folder, locate your PP, search for the property 'Spindle CW' in the 'M codes' section, click on the |..| button at the right side of the line to run the text editor and change the M3 to

M3
G4 Pxxx

where xxx is the delay in ms or in seconds, depending of your software.

Hello

It would be a better to set this in Mach3

menu config/port&pin, spindle setup tabs



in the general parameters 'box', CW Delay Spin Up > give a value in seconds or ms depending of the setting in the general config (right most column > G04 Dwell in ms)



if Dwell is in ms, enter 3000 in 'CW Delay Spin Up', otherwise, enter 3

PS: I f you are using an Ethernet smoothstepper, the delay is always given in seconds, even if mach is set in ms.

Hello Steve

Cambam can read STL and 3DS files (3D), and it seems that this file is available in 3DS format, so you can open it in CB (for 3D machining)

For printing, you certainly need to convert it to STL ; most software can read 3DS and save STL (I assume MeshLab can do that)

Edit: a 'free file format conversion' button is also available on the web page Wink

Hello

Quote
I am unable to position the bottom of the object at Z=-10 so that the first 3 mm on top should be simply be milled out and the bottom of the object is the bottom of the stock. I tried to use the Transform, Align panel but I have not been able to achieve the desired position.

In the transform/align window:

set X and Y to none
set Z to 'lower' and in the text box below the Z column, enter -10 then hit apply.

the lower part of the 3D object will be aligned to -10

an example at 0:39 on Y axis

But... also... If you do not know how to do things like 'properly' break lines (and such) in the UI, then it can lead to improper edits.

Hum ... I don't understand.

I prefer to edit the PP sections from CB because CB use it's own editor and I'm sure that the text encoding is right and that the right 'end of line' 'carriage return' are used. And it is even more needed on a language like French that use non ANSI characters like etc ... With an editor like notepad, that can cause problems.

In addition, reading an XML file is not as 'clear' than editing the data in the property grid.

Remember to do a >tools>reload post processors after making your changes.

Hello

Only needed if you modify the XML "by hand" (by editing the XML with a text editor), or if you add a new PP from the external side of Cambam.

If you do the changes from the Cambam UI in the system tab, you can use the modified PP immediately.

Hello

Go to the system tab, locate your linux post processor under the post processor folder then in the property grid, edit the Header, Footer and Toolchange properties, then save it.

note that for things like work plane, arc mode etc ..there is macros that can return value according to what is set in your cambam project (machining folder, machining ops, etc)

Hello

Quote
- shouldn't 'Paste Format' work only on the same type of MOP and be disabled if the types differ?

No, it works even on <> MOP type (and it's a good thing)

Quote
- Undo in this case does not restore the previous state.

Exact, and even if the 2 MOP are of the same type, an UNDO just after a 'Paste format' reset all values to 0 ; that is certainly a bug

same bug on V1.0 R13

Re. "Here is a video with this 5/16" endmill"

It looks to me like the material is not uniform thickness, meaning one side is slightly thicker and the vice is not gripping it on the thinner side.
Or the vice jaws are not parallel.

Hello

Yep, the part seems to rotate CW around its right side !

Hello

I don't know if it is the case, but I suspect that on your DXF the lines are not on the same level (in other words, the DXF is in 3D) and you get a set of lines for each level of the part

If you look at the drawing (the just imported DXF) from the top view (standard XY) in CB, you can't see it, but if you switch to front plane (XZ) or, better, if you rotate the display (alt + right click), I think you will see 3 levels of lines.

You must select the lines by levels to join them ; if you select lines that are on different levels, you'll get unpredictable results as on your shape that seems to be ok on top view but is bad in ISO view (picture).

If after a dxf import, you end up with multiple line levels, it can be a good idea to first move each group of lines that constitute a level to different layers ; it's more easy to work.

also if you need to force all lines to Z=0 before joining (it's preferable), you can use the flatten plugin.

http://www.atelier-des-fougeres.fr/Cambam/Aide/Plugins/flatten.html

The small video in attachment show what I explain about multiple level of lines.
