Re: Ramp entry (helix) too steep

The term "IgnoreAbove" probably carries little meaning unless the user already understands the shorthand notation. If I understand the logic, then "BeginAtStartDepth" might be a bit clearer. Good suggestion. Actually, I went even further and called them UseStartDepth and DressupStartDepth. PR is he...

Re: rml containing curves runs incorrectly on Roland MDX-40A

I spent a few minutes looking at this.. I don't have any experience in Roland machines or that control language. Wow, what a language. :) But I may have a clue about what is going on. Two things: First, there is no support for arc movements in the language, so the post processor tries to split them ...

Re: Ramp entry (helix) too steep

Here's the commit: https://github.com/pekkaroi/FreeCAD/commit/cd2947f7f31f0a5f33194ccc58ca8bde0a25a53f So now the dressup contains new parameters IgnoreAbove (true/false) and IgnoreAboveDepth. (Please, come up with better names). The IgnoreAboveDepth is set to the start depth of the base op when the...

Re: Ramp entry (helix) too steep

Hi roivai, looks good! Did you change the behavior of the first round only by the helical ramp or at every ramp style? I changed all the ramp/helix entry methods. `PathDressup.baseOp` is what you're looking for - although, it might not be what the user wants. There might be dressups that have speci...

Re: Ramp entry (helix) too steep

Would that address the steepness issue? I think it would. I tried that out and it works quite OK (based on the paths shown here, no actual machining or even simulation tried..) So I added a parameter to the dressup to ignore movements above start depth of the base object. To test I created a helix ...

Re: Ramp entry (helix) too steep

Hi, The ramp/helix dressup is quite dummy. The helix algorithm simply looks for a straight down non-rapid movement and a closed loop of constant-Z movement after that. If such condition is found, it is replaced with a helix covering the depth of the original Z depth. So because the original operatio...

Multiline preamble for post processors

Hi, I don't know if this question would be for the GUI design or Path, but anyway, I tried to modify the preamble argument for LinuxCNC post processor. The default, according to the source code is "G17\nG90". I'd like to add one more line to that, but it appears that if I try to write to the job set...

Re: dressup minor issues

Hmm, seems that I'm late for this party.. Here's the commit, but I suppose the release has been done already?
