Developments on my Home built 5C CNC Lathe - Polar interp. and Live tooling

I have not had this problem. 

it's possible that your build created a linuxcnc-dev deb too. Do you see one? (also docs debs and c headers) 

 

Thanks Andy. I have sorted the issue. As you suspected, there was a linuxcnc-dev deb as well which I had not installed. So installing that sorted the non-availability of halcompile. There is also a linuxcnc-dbgsym deb which I have installed - not sure if it is needed

Hello JoeNoci,

I saw your 5C CNC lathe blog. You did a very nice job. Great report, very inspirational!

I am also into mills and lathes, CNC and manual, and more fun stuff ... I work with Fusion 360 CAD/CAM, using my own post processor routine in Fusion to tailor the G-code for my CNC mill. My plan for this year is to build a small "custom" CNC lathe and thus my interest in your approach to this subject

Greetings from Germany

Thanks Stefan. I am 'almost' complete with the lathe..Not sure something like this is ever complete though. I will post some of the final photos and construction in my post within the 'Show your Stuff' topic, in the coming week or two..

Looking for the next project now...

Hello JoeNoci,

great. I will look at your pictures once you have posted them. I own a manual Weiler Condor lathe and I really miss CNC lathe capabilities. Hence, my plan for 2020 to build a small CNC lathe.

NoJo,

I'm starting my own C-axis lathe project similar to the one you documented here and in another thread.

The two really murky areas for me are:

• Polar interpolation
• Spindle/C-axis switching (using the same motor)

Would you be able to provide your (hopefully working) configuration and comp files?  And perhaps an explanation of how you managed to glue everything together?  I found a single post from you a while back where you attached a comp and hal file, but they look like they were created during development and not 'final' files.

You mentioned working with Andy Pugh on it, but I've been unable to find any discussions you and Andy had regarding the switchable C-axis/spindle function.  Perhaps those were done outside this forum.

Thanks,
R
