Hi everyone,

Since I haven't made much progress with the inverters and electrical hardware (i try to get the SIEMENS S120 running but its hard with linuxCNC ;( ),

I've been working on a concept for the hand-control-panel in the meantime. I dont like the original one that much, so I'm trying to build a new one and keep it as compact as possible.

I like the idea of it being mounted to the bed carriage, similar to a conventional maschines. I plan to design the lever for forward/reverse operation in a way similar to what was done with VDF. In the neutral position, it will lock in place, and to activate it, you’ll need to push it slightly towards the negative Z direction first. Then, you can move it up for left rotation or down for right rotation. All three positions will have a locking mechanism in the center, as mentioned. This is for safety and prevents unintentional movement when you have your head near the spindle and might get caught on something like your clothing.

For the keys I'm thinking about adding a Stream Deck instead of real switches. So i can programm different functions to the setup in the future. Could be very handy.
   

Best regards,
Tom

Hi all,

Today i did a test using the clothoid algo.

It turns out, when doing a fast clothoid fit, (using deviation as trim dist) this takes around 0.5ms.
Everything is going well.

When using the excact clothoid fit method, it takes time up to ~200ms when it has difficulties to find a fit.
I will find a solution for this later on.

Most off time the clohtoid fits are ok. I have seen cases where the clothoid fit result looks like overfitting.
This could be investegated later on.

Here some 3d clothoid fit examples. Using look ahead = using endvel.
So far i am happy with the results.
