awesome!

When will there be a beta ready for testing?

:lolb: Poor Steve, Nick you keep dangling that so, so tempting calculator in front of him. Maybe you could put your father Xmas hat on at some point  :naughty:

[size=78%]When will there be a beta ready for testing?[/size]



In the many years of my professional software-development, I learned one thing: Never give a date when the work will be finished.


Current state is:
The main window (with lift, speed and acceleration) is stable and I no longer get it to hang.
The window with the forces from valve spring and acceleration works.
The window with the lobe sketch works now (again). I simplified the code and the graph now properly centers. I'll add some eye-candy (I guess today).
These three windows interact with each other properly.


G-code generation is the place with lots of detail-work (but essential details) is left:
Some parts only work CW or CCW, some ignore the plateau. Grinding and milling isn't implemented (only milling, but that once was grinding, so I had that code already. The difference is not complicated). That's "only" adding "a bit" of code (without breaking the one that works). The stitcher-part is completely missing. That will require saving all setting. And that works just *very* rudimentary.
Currently, G-code generation is a stand-alone-program. That makes debugging for me much easier. But also makes the program kind of useless.

Here is something to laugh!
Facets-cutting method with a plateau. I didn't expect it to be **that** wrong.  :ROFL:
Without plateau, it (still) works. CW and CCW.


Merry X-mas!

Don't worry! Project goes on, but I took a few days off.
In the meantime, I have improved PrimSim. Now, I can click on any line in the graphics. Then that line flashes a few times and the corresponding line in the G-code is scrolled to and marked. Also, pressing F1 within the G-code listing flashes the line in the graphics.
Both methods show XYZA of the start point and the end point.


I'll be quite occupied the next weeks: Have to make 3 permanent molds for zink-castings and a bunch of Porsche 911 crankshafts ...

Did you show the crank to some people and end up taking orders?

Can't tell the whole story. But yes, the first batch is "gone". And the next batch will be 40 - X (X being the ones that are rejects).

Edit:
The disk cutter (for milling) is good for about 8 crankshafts. Then it needs regrinding. I hope I find that sheet again where I wrote down the angles. Regrinding is a bit tricky, as every odd tooth is cutting left and the even ones right. They are side-cutting too. A circular saw doesn't work.
I have looked for a carbide cutter, but they start at 400 € (custom made). With inserts, they cost 1000 € and up.  :disappointed:

Steve:

While your waiting for this program to be finished you can grind a cam now with Gcam. We developed it several months ago and posted a notice about it here.

http://www.homemodelenginemachinist.com/f26/grinding-cams-cnc-program-beta-test-21127/

 We'd be happy to have some people give it a try. I've ground a couple of dozen cam lobes with it and works very well. We need the feedback.
