Trochoidal Pocket & Profile MOPs plugin (HSM)

[dh42]

Hello jk

I'm working on translation for your plugin and I fall on a little problem because some texts are already used in regular Cambam MOP.

'Step Over' is used for the header of the section (1) and translated as "contrôle des déplacements latéraux" in French.

'StepOver', without space, is used for the step over value property (2) and in French the 2 texts are different ("recouvrement" for this one), but as you can see on the picture, both are the same because in the plugin the 'Step Over' text is used in place of 'StepOver'. Can you change that ?

note also that 'Stepover' with no space and a 'o' instead 'O' is used by another plugin.  

I really not understand what is the "Segmented slice derating" and what it do exactly...  

Nice job

newlinuxuser,

Did the v1.1 worked ? Never used CB on linux. I have virtual machine with ubuntu, maybe I could install CB there and check if nothing helps.

dh42,

Thank you for the translation efforts, didn't think about translation yet, a lot of text resources aren't wrapped in Translate.

Not sure if 'Segmented slice derating' setting will survive the next versions :-) Its effect is visible on incomplete (segmented) slices, there the path make a round and meet already milled area. Since it's already milled,
center part of slice is cutting air, and may be removed. Actual stepover is becoming less. This setting allows
to choose stepover for such slices. 0 means 'use actual stepover', 1 means 'use original stepover', other values
are in between. Maybe a picture will explain it better.

[newlinuxuser]

Yes, the v1.1 works perfectly in linux.

Updated first post with v1.3

* new tool engagement estimator, true angle of engagement is analyzed
effect is most pronounced on a narrow passages, slices are compressing - see picture

* change of the way feedrates are passed to the CB g-code generator
* fix for compatibility with older version of CB libraries (used in Linux version)
* setting for the feedrate of opening spiral
* mop-specific feedrates are now default to 0 (means 'use cut feedrate') to be consistent with other feedrates in  CB
* fixes

Just tried it here; http://www.cambam.co.uk/forum/index.php?topic=6229.msg49451#msg49451

looks great !

[newlinuxuser]

Just tried on linux, errors fixed, works well!

Thank you.

I don't do much pocketing but this is really exciting to see!

Hello,

Thank you for the translation efforts, didn't think about translation yet, a lot of text resources aren't wrapped in Translate.

All texts in the treeview (properties and help texts) and menu are translatable, the only one that is missing is the bubble for the toolbar icon, I think it's not necessary to translate all log texts that are written in the log window ; that increase dramatically the translation file.

thanks for changing the text for the Step Over, now it use the standard translation for this property.

EDIT: it seems that the leadin spiral is reverted compared to the rest of the flat spiral.

also, the spiral is both in horizontal and Z direction ; on other mop, the spiral is only in Z.

another nice addition would be the management of the '0' value for the spiral angle for the spiral leadin. On other MOP, if 0 is used the MOP calculate automatically an angle to obtain one full spire for the given depth increment.

Thanks )

Didn't expected CamBam is running just great on linux. A little slow on painting, but it's a likely a virtual machine issue.

Popup text on toolbar icon won't be translated, it's a used to regulate conflict with Custom CAM Toolbar plugin )

Leadin spiral reversal is by design. If flat spiral is expanding CW, outer walls are milled and mill direction is conventional (spindle is CW). Leadin spiral is collapsing CCW, inner walls are milled and mill direction is conventional too (first loop is a full slotting of course).

Spiral angle = 0 gives the right result, full length of source polyline is used to reach the given depth.
But in this case source polyline = flat spiral, so spiral is fully unwinded :-)
Internally I call native CB lead-in generator on a flat spiral, he does some inner magic and returns Z-spiral.

---
Just thought it may be unclear:

Flat spiral is not a lead-in, it's a part of pocketing toolpath (spiral + slices)
Z-spiral or tangent lead-ins are lead-ins (sic) may be used or not. They are generated based on a pocketing toolpath. I apply them to the spiral part of toolpath only, otherwise they make a mess.

just find a pb case

dh42,

relax min stepover a little. 0.88 instead of default 0.9 fixes the problem

[dh42]

Just to say, It works also on the V1.0 alpha (development version) and the new MOP is totally recognized

Hello,

Ah ok, I thought you need to create it yourself. (I never explore MOP creation)

In this case I understand why this result ; the leadin is applied to the first toolpath of a pocket, but in this case, the first toolpath is the whole flat spiral.

Maybe, the way to obtain a "only Z" spiral for the leadin is to apply it to a circle centered on the flat spiral, so you get the same as a spiral drill for the leadin instead of an horizontal + vertical helix.

I assume that the circle must have a diameter a little smaller than the cutter diameter, and of course that it must not be "attached" to the flat spiral so only the circle is done with a leadin. Also, in this case the spiral must not start at the center but at the circle diameter.

I think metal workers will like this plugin !

Can I get a version of this already compiled? Thanks.
