Ok I cannot make any sense of this I have been trying to update to 2.10 for the past few hours thinking that 2.9 might be the root of anll my problems and can’t figure it out. I went into sympathetic package manager then repositories and deleted the two lunixcnc.com lines and refreshed. I then created a new one as follows
buildbot2.highlab.com/debian/ 
bookworm
master-uspace

then when I enter “sudo apt update” in the terminal it gives me the error I attached bellow. I have read through these post several times, but just end up more confused each time.

Some clarification would be amazing, thank you.

Thank you for this. That did the trick, but I have a couple of questions.
How am I running a raspberry pi all of a sudden?
And
Is it possible to install a nvidia graphics card and still use Linuxcnc?
Thanks again

My setup isn't actually *that* primitive. The touch-off plate is a very nice bar of aluminum that is about 2" long and *exactly* 3/8" on every side. I found it in my scrap box, and it already had a threaded hole in one side. Very convenient. And because it's square, I can use it in almost any orientation. (I remeasure it once in a while because I still can't believe that it's exactly square in cross-section.)

In addition to the panel, I have a (shell) script which will tail the probe log, and based on the last two probe entries it will give me either the angle at which the work is sitting (if the probes were both from the same side) or the center point between the probes (if they were in opposite directions). As output it prints the G10 L20 line necessary to make use of the result. So I can do much of what Easyprobe does. Just not quite as Easy.

No restart of the PC required for running different configs.

 

Indeed. That is the intention.

The old machines such as the Hommel require quite a lot of work to setup, because everything is mechanical, and drive axles for auto feed and such have to be reconfigured manually too. In my modernized version accessories such as for example a rotary table or an XY table get their own built in stepper motor(s), and you just plug it into the control box and load the fitting configuration. So you first reconfigure the hardware, and you load the (preconfigured) corresponding configuration. Goal is to have 4 to 8 different configurations. For example for:

1. Vertical milling.
2. Horizontal milling.
3. Line Boring.
4. 4th / possible 5th axis configuration.

Below a picture of the same Hommel machine, but configured as a lathe.
 

So you can start with a 3 axis machine, use it to make a rotary table, and then extend it to 4 or even full 5 axis, but also go back to 3 axis, because that allows for more rigidity and heavier machining. Andysmachines has made some excellent youtube tutorials on gear milling, and this has a lot of error prone manual machining, which also gets boring very quickly. And this begs for more automation. The goal is not to work with mechanical CAD that spits out a big G code file, but to write some python code that generates some G code for special applications. For example gear cutting with a disk mill, or with a profile mill. The number of teeth for the gear is then just a number in a for loop (and a radius change).

So the question still is: How do you load different configurations in LinuxCNC? Is this a command line option, do you have to fiddle with configuration files outside of LinuxCNC? Does a configuration change also reprogram the Mesa card without a hard reset?

My experience with LinuxCNC is very limited. I did some short tests with Machinekit some 10 years ago, and recently I tried it on 3 different PC's, but latency tests were atrocious, so I need better hardware. I'm also still in doubt to whether go with LinuxCNC or to stick with something simpler such as GRBL. Worst case scenario for multiple configurations, is to write a script that interprets G code, and then swaps axis and direction, and write it back to another file.

Someone here told me to get a now I cannot remember which chipset, but SMC Wireless USB 2.0 Adapter matched it on Amazon. I just plugged it in and now, instead of 24 Kbps, I have 15 Mbps. (My shop is several feet below the router. A refrigerator is also in the path.)

Yes. I also think its the easies solution.
Darlington transistors at each driver is way more work.

Thanks for the hint. Will do it with an array.

R denotes the XY rotation angle around the Z axis.

Looks like there has been a discussion about it but it seems to have stalled:
github.com/LinuxCNC/linuxcnc/issues/3064

Hehe,

yes, I never ever thought about having z positive down

Have you tried in TwinCAT? Does it work there? If not, the device is faulty.

You can still get ULN2003's in DIP packages
so for three axis only one chip (perhaps in 
a socket) on a bit of perfboard would do.
 

So,when bought the machine i started with the idea of keeping the machine as it was, but after a week  of figuring out how the old system work, it let me do only one job then the motor of the y axis broke and leaved me. So now i was thinking a retrokit to mount on my machine because this  have to work hard and last. So idk i can change all the brain and use linuxcnc and leave 3 motors and buy another one new and with time and money i can change all of them . Or i can buy new motors and i don't touch it ever again(only for maintenance ). 
Btw guys do you have  a nice shop were to buy servo motors like the Delta B2 (ship in europe) i saw the motors on Namicam and Motion Control products, seem's good placees idk about the price but seem good pricing . And i need an advice leadshine if it's a good product for professional work . Because they are more cheap than Delta and i found them at really good price.
Thank's for your answers.

 

Yes, you are right. Didnt thought about darlingtons, but yes, they will be fast enough for this configuration.

So I will have to build a small board in between.

After fooling around for a while, I decided to retain the positive-Z-up configuration. It's basically what modern CNC machines expect, I gather. Also, EasyProbe doesn't work in the positive-Z-down configuration.

I would suggest using something like a ULN2003 as a level shifter
