XHC WHB04B development?

I think there is an oversight in the homing model. I can't see why joint axes can't move in unison before they are homed. If my first machine didn't have a gantry, maybe I'd have a different view. I've often wondered why this treats each side or a gantry as seperate axes when they are always joined at the hip!

There are always situations with tool and work piece geometries
and unfortunate stop situations where one need to stick the nose (eyes) close up
to guide the tool out of the situation before it's free for homing.
I guess the best is to leave it up to the user if he wants to jog before homing.

Good morning. I compiled LinuxCNC master version 2.10.0 running in place, downloading it from Git, about a month ago. How can I update the source code to the current version and then recompile it with the latest bug fixes?

Thanks

Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5

Category: Installing LinuxCNC

I was thinking of building a new image for the Raspberry Pi 5. It will feature 2.10 to get scurve planner and be on Trixie and use the 6.12.74 RT kernel
Is there any reason not to use our current installer framework? 
Is there anything that desperately needs changing?

It just seems to be still the best way forward and I have the template to start with.

Get a real machine, rodw :)
In a milling machine and lathe, there are many situations where you may need to jog before homing.
To get the tool out of the way before homing for example.
 

I had a mill and am building another. I thought HOME_SEQUENCE was designed to get the tool out of the road

@rodw: Jogging in manual mode is fine. My machine can not jog in teleop mode due to I have two Y axis servo motors. The only thing the WHB component does after my PR is:
- Change to teleop mode if not homed (which fails on my machine but on others, it will do that) -> You can jog before homing any special action
- Change to manual mode if homed AND program is idle -> You can jog after homing without any special action

In this case its far better to disable motion before homing with a simple change to the ini file. I still have no idea why people want to move or jog before homing. None of my machines allow this! And yes, one was a XYYZ gantry plasma table that jogged with a pendant perfectly!

G71 and friends exist mainly as an alternative to CAM, to make hand-coding easier.
I don't know of any CAM system that generates G71 (which isn't to say that there aren't any). But I don't think much would be gained from doing so.
 
 


I am not familiar with any other CAM software for turning, but Fusion360 / HSMworks / Inventor CAM can do this.

The standard LinuxCNC turning postprocessor from the HSM library does not work without corrections (it uses Fanuc-style UVW for incremental offsets, which LinuxCNC does not understand). I don't know who added this post or why these corrections haven't been made in almost ten years.

G7X canned cycles are also not defined in this postprocessor, but you can add them by following the standard Fanuc turning postprocessor example. This will probably require verification and correction to match the LinuxCNC code-style. The cycles are defined in the following functions:
function onCyclePath()
function onCyclePathEnd()

7i97+8i20 error function not found

From the start I was having some serial communication errors now and then, that were caused by something regarding to Y-axis movement. Sometimes the issue happened once in couple months, but two weeks ago it happened almost every time I was using the machine. I did some research and tested and investigated pretty much everything, and I noticed that with only the cfq=f, using only the fanuc grayscale for bldc commutation, there were one spot four times in revolution that the motor did not have that much torque, and probably caused rotor phase current to rise quickly causing EMI issues.

But after that was discovered, I decided that i want to use the qi mode, so possible encoder replacement could be easier and cheaper in future if needed to be done. I have been fiddling with the init settings. I want the rotor alignment sequence to work in a way that when I open linuxcnc for the first time, press machine on button in GUI (F2), the rotor will do the rotor alignment sequence that ends when it finds the index mark. But, if the power-off or E-stop is pressed and after that turned back on, the alignment sequence would not be done again, because the encoder count is not interrupted and the rotor alignment should correspond to that still. I haven't had any luck with getting this to work like that, so now id like some advice or if somebody has used same kind of configuration for the same thing I would be grateful.


Here is the hal confiq from the Y-axis and ini file. So this works OK for the Y-axis now, exept id like to make the rotor homing only once:

Great work so far.
I am just not sure i fully understand it all yet.
Does that mean that with the installed PR from end of 2025, SyncToRefClock=True fixes it all? Or is the currently open PR still needed?

Thanks!

Tested the latest changes, and everything works as expected. Thank you!

Yeah. I also grepped for usleep at one point, but didn't really bother trying to figure out if it will cause issues elsewhere. If you go back to some of the first posts, you see I also considered writing a completely new component. Part of the reason for that was to have a state model and avoid these blocking sleep calls. The other part was that I think that the level of abstractions used is bordering on ridiculous for the application. The xhc-hb04.cc component has one order of magnitude less lines of code and does more or less the same thing. But now that you are fixing things, and with my own firmware, I personally don't see a need for a completely new component at this time.
