Using the 12v rail from your PC negates the protection the optos are used for.

I suggest to forget all the BS you've learnt from the Hipster Maker crowd and read & learn by someone that knows his stuff.

This is a good start, written by the guy that designed the TEC-1 sbc back in '83 or '84:

Ok we get you don't get Python, they are just libraries, not dependencies, the same as you need libs for C & C++ and other things.

WTF you're dragging up a thread that's over 12 months old and repeating your opinions regarding Python & Java & not adding adding that is of relevance, every time you post it has nothing of importance or relevance.

Yeah I get the irony, but (insert vulgar speech here) you're such a (insert vulgar speech here) waste of space.

Hello everyone,I am a new LinuxCNC user and developer. This time, I would like to use LinuxCNC in combination with my cutting simulation process. I have encountered some problems and would like to know if there are any known solutions in LinuxCNC. If not, I am interested in developing features similar to G43.4 and G43.5.Before we get into the details, let me provide some context. I am running LinuxCNC 2.9.4 on Debian 12 with PREEMPT_RT. Please note that for my simulation process, real-time (RT) capability is not a strict requirement. My simulation uses the configuration from , which matches the machine type I need.Here is my understanding of the five-axis xyzab-tdr support:
The key is the toolpath (TP) transformation. Five-axis machines are different because they require transforming the workspace coordinates to real joint positions, which involves both forward and inverse kinematics. The xyzab-tdr configuration provides these transformations. The main parameters for these transformations are seven in total: , , , , , , and . The , , , , , and  define the machine’s geometry, while  functions similarly to Fanuc's G43.4 RTCP (Rotating Tool Center Point) tool compensation.In RTCP, G-code is typically provided in two forms:Fanuc-like: Siemens-like:My questions are:

1. In Fanuc, G43.4 is modal. Does LinuxCNC use the TP transformation as a modal mode as well? In other words, when using five-axis TP, is G43 equivalent to G43.4 in LinuxCNC?
2. The IJK parameters are used for Freeform Surface toolpaths. Does the G-code parser in LinuxCNC support IJK-style input?

Thank you in advance for your help and insights!

I’m not sure if you have any time to spare, but I’d be happy to compensate you for it. Even if you’re not local, I’d be grateful for any kind of remote tutoring or guidance—video call, screen share, whatever works for you.

I’m based in California and have already put a lot of time into getting this setup working, but I’m still stuck. The learning curve has been steeper than I expected, and I really need to move forward.

At the moment, I’m struggling with tuning the driver, displaying the distance between the Z and W axes, and getting the control buttons to function properly. Since you’ve done similar setups, I thought you might be able to help me through some of this and save me from going in circles.

If you can’t do it yourself, I’d really appreciate a referral to someone who’s handled a similar project and could assist remotely. Otherwise, I may end up switching to Centroid just to get our shop running and meet deadlines.
