Re: dressup minor issues

I just ran an aluminum job and used Ramp dress-up on it. One thing that I noticed that surprised me was that the Ramp-Angle is specified relative to the Tool, not the Job, and so if I want to specify a Steep Ramp, I approach 0-Deg, and for a Shallow Ramp, I approach 90-Deg. This seems counter-intui...

Re: Harebrained ideas and other noise. (Milling Edge Features)

Intresting stuff! That trochoidal milling (am I typing it right? :) ) is definitely something worth looking into. It of course applies on any kind of pocket milling or clearing, not only clearing some user-defined spot. BTW, I saw some PR about this on github already, is there some other development...

Re: CAM simulation for the Path Workbench

Yes we have, - but it dosn't work on a operation with a dressup. Also array dosn't work on a püeration with dressup. Last tested with AppImage I fixed this one - made PathArray to accept Dressups. The commit is here: https://github.com/pekkaroi/FreeCAD/commit/67fa14307774adbf32e311a8f137f00c1f4d2da...

Or create a new macro and run it instead of using the python console.
Yes - that's how I did it, I created a macro that contained the code I attached earlier.

Re: Approximate/rough guess of milling time

...The rapid feedrate was set to 0 in your file. I set it to 5mm/sec... How did you change that? Here it´s blocked! In user interface that is. Did you try clicking this one? 2018-02-18-193642_1920x1080_scrot.png By default those feed rates are bound to the setup sheet values, so another option is t...

Re: Approximate/rough guess of milling time

Easter is coming and... one would then of course have a virtual Easter egg mold! ;) I could not make the script provided by roivai to work. Anyone else like to try? . Easter_egg_Milling_test.fcstd Did you get a "division by zero" error? The rapid feedrate was set to 0 in your file. I set it to 5mm/...

Re: Approximate/rough guess of milling time

Anyone want to take a stab at coding this up in a macro so we can get some comparisons to linuxcnc and camotics for benchmark? Here's a quick scratch I made. It seems to output a number, I really did not have time to analyze/compare if it makes any sense. Does not support drilling cycles. One side ...

Re: Drilling feed speed?

Hi and welcome!

LinuxCNC expects feed rates in mm/min (or inch/min if set for inches). So that 10mm/s is translated to 10*60=600mm/min.

Re: Tool-Library: Cutting Edge Angle

I agree that a big rework should be done. But as a short-term solution something should be done to allow successful simulations, if simulator expects that tool angle of a flat end mill is 180deg and tool editor allows only angles up to 90deg, i.e. assumes that the given angle means the angle of "sin...

Re: Offby one in the tool table: Tooltype

Created PR1286. The issue with line endings bothered me so I created a new branch with fixed encoding to not mess git diff history - I noticed that the c++ files are having Windows style CRLF line ending on purpose according to this guide
