Z Cut Cannot be Positive

[Zack W]

In version 8.991, I can’t seem to set a Z cut to a positive value. This would be really nice for a lot of reasons, specifically on the machine I’m using it’s nigh on impossible to re-home the Z axis.

Hi Gector,

First: you are using an older version: current version is 8.992.
Second: even if you are using beta v 8.991 you still have the machinist_setting which when checked will allow what you want.
(In the following picture I use my working version of FlatCAM but the setting is in the same place in 8.991 and some versions before too).

Ah, that’d do it.

Tangentially, what version of svg.path is supposed to be used? I have to remove an import in flatcamParsers/ParseSVG.py when using svg.path v4.0.2. Oddly enough those classes do seem to be present in path.py. [This applies to both 0.991 and 0.992 for me.]

[Marius Stanciu]

…>= 4.0 should be OK.

It seems to me as some errors in the packaging, I assume you are using the beta in a Unix-like environment where I’ve seen the issue appear.
You could try to build the package yourself from the sources.

[Zack W]

I will build the package from source and let you know. I don’t know why it’s acting up, seems like it should be fine.

Still in 8.991 (I need working gcode generation); Enabling Unsafe Machinist settings and setting a tool to have a positve Z cut height still generates GCode with a negative cut height. Is this fixed in 8.992?

[Marius Stanciu]

You can test …

[Zack W]

Of course, sorry.

The lack of positive Z vibes seems to be fixed in the beta branch.

Having built svg.path from https://github.com/regebro/svg.path, the issue persists with the import error in versions of svg.path above ~3.1. It looks like Move and Close are automatically imported in svg/path/__init__.py.

gector@Minotaur ~/D/a/jpcgt-flatcam-64e463cd64fb> pip3 show svg.path
Name: svg.path

The solution may be to remove the following lines from appParsers/ParseSVG.py

 24 from svg.path.path import Move
 25 from svg.path.path import Close

Hopefully solving this error:

gector@Minotaur ~/D/a/jpcgt-flatcam-64e463cd64fb> python3.6 FlatCAM.py -v
Traceback (most recent call last):

    from svg.path.path import Move
ImportError: cannot import name 'Move'

Or my installation is damaged, it wouldn’t be the first time.

Hope this helps!

They may be automatically included but I do not do:
import svg.path

I will try to modify the program and use the above and instead of calling Close() will do something like svg.path.Close()

Issue solved by changing a setting in Preferences.
