Re: CNC: Should I use forstner bits or a 1/4" milling bit?

The answer depends on your CNC. Personally I haven't seen a Forstner bit rated for over 750 RPM, and the slowest my CNC spindle will go is 6,000 RPM, so I can't use Forstner bits with my CNC. I use a 1/4" endmill instead. If I had a CNC that could do 500 RPM I might try a Forstner bit in that. ...

Drilling: can't set peck retract, problem Z rapids

I set out to recreate old job (created with version 0.19-21514) using latest weekly build. I ran into two issues: 1. the drilling operation is set with Peck Enabled = true and a Retract Height of 5.0, but the G-Code always has 'R0.000'. I tried various values for the Retract Height but it did not ma...

Re: Difficulties installing OpenCamLib

Github no longer supports the git:// protocol - see Improving Git protocol security on GitHub.

Try

Code: Select all

git clone https://github.com/aewallin/opencamlib.git
That worked for me, and I'm also on Ubuntu 20.04.

Re: how do I get changes in tool library to update in job operations?

You don't need to delete an operation to get it to use a new tool diameter. 1. add a new tool controller that uses the updated tool 2. edit all the operations in the job, switching them from the old tool controller to the new tool controller 3. delete the old tool controller I had to do this a numbe...

Re: How to add my CNC bits?

I have used the V-bit shape successfully with 1/8" engraving bits that look like the ones in your picture. My settings:
Diameter: 3.17 mm
Shank Diameter: 3.17 mm

Re: can't create a toolpath for a fillet

A waterline operation worked well for me: WLS-Schutzkappe_Waterline_Screenshot_20211214.png New file: WLS-Schutzkappe_Waterline.FCStd Notes: 1. Waterline toolpaths are limited by the Bound Box, so I changed that to Stock and then increased the size of the Stock in the Job setup. 2. I set the operati...

Re: I'm confused by 0.20s Tool system

https://wiki.freecadweb.org/Path_Tools has the overview of the new tool system.

After that, https://wiki.freecadweb.org/Path_Tools covers creating a new shape if the ones that come with FreeCAD aren't close enough to what you need.

Re: Proposed cut pattern updates: PR #4965

The way the image in the last screenshot shows the meaning of the various heights and depths right in the same dialog where you set the heights and depths is really nice. That would eliminate a lot of confusion and needing to check the documentation.

Re: Separate Gcode Files for each operation

Personally I handle tool changes by creating a separate job for each tool. A single job can include multiple operations but it won't include a tool change.

I include an abbreviation for the tool in the job name, so the Gcode file name tells me which tool it needs.

Re: is this a Path Helix WB task

The Path workbench is the one to use to generate toolpaths. (There is not a "Path Helix" workbench as far as I can tell.) This is the correct forum for posts related to toolpaths and CNC usage. There is some support for a 4th axis, and I think it would be able to generate the toolpaths nee...
