Thanks, I'll do this later today

W5100S-EVB-PICO stepgenerator and encoder driver

Category: Driver Boards

i have some questions, please explain to me "low resolution encoder can produce velocity as 0,0,3 not 1,1,1", "digital signal sampling too quickly.", how do you mange the digital signal sampling too quickly problem if you using hardware encoder counter without external hardware? how do you manage data integrity problem of UDP communication, i dont see any code to check the sent and received data is valid. Do you tested my code in real hardware? If so, open an issue in the github page. My project is in development and i want to fix all bugs that come in the future, but i don't react to theories. If you want to participate, fork the project (test branch), make changes you like, test it  and make a pull request.

PARAMETER_FILE = linuxcnc.var
 
I use clean configuration created by PNCCONF.
My linuxcnc version is 2.10

If I don't enter anything from the keyboard and just press the OK button in the window, the coordinates are reset.
but if I enter any number, the option to confirm with the OK button disappears.

After I click the OK button, I open the linuxcnc.var file and see that the values have been written
5221    37.000000
5222    0.000000
5223    -10.443750
 
But if I enter any number from the keyboard, the option to confirm disappears, and I see the inscription "File not open"

Interfaces & linear scale for LinuxCNC

Category: General LinuxCNC Questions

Hi,
I originally wanted to run a cheap DIY cnc machine using an old Intel Atom dualcore computer which has an LPT connector. But meanwhile I start thinking about higher quality components.

Same specs:
-stepper motors (already exist)
-linear rails for a work area of 1000/600/200mm (already exist)
-spindle Kress FME800 (already exists)
-stepper driver board with 5x Toshiba TB6560 (already exists)
-USB connected hand controller/job wheel LHB04 (already exists)

Now I wonder if I'd better go for an network/USB controlled Mesa card to get rid of that old Intel Atom computer and be able to use any machine (probably a modern notebook).

Also I would like to bux linear scales for my build, but couldn't figure out how they would be connected to LinuxCNC.
Is there a lis with reliable (but not too expensive) supportet linear scales?

And would you rather ust the Toshiba stepper driver board listet above or get some modern alternative?

Since I didn't really start building it, I'm free to change components for the good :)

I'm going to weld the frame for my machine. So I wonder what's the best way to start? At the moment I think I'm going to build z-axis first and depending on it's dimensions I can design the x-axis, then Y-axis.
But for designing the z-axis I need to know which linear scale system I need to mount and what size it is.

Since this CNC machine is intended to build electrical guitars, I don't require the highest precision, but I'd like to have as small tollerances as possilbe for a reliable pricetag.

Mo pichurs... for your enjoyment (or hate, you do you...)

 
 
 

The atc mounting arms are just pure brute force right now. I need to refine them be a little lighter and a lot less expensive.

I noticed the ENDSUB doesn't match the SUB in tool-length-reset.

Probe tripped during non-probe move deadlock

Category: General LinuxCNC Questions

Hi Andy,
I believe that the issue I'm describing is exactly the one here:
github.com/LinuxCNC/linuxcnc/issues/2926

The last comment from that issue was you asking about the motion.motion-type following motion.probe-input going high.
I've looked in the halscope and it does seem that motion.motion-type remains at a value of 5 (Probing) until deceleration is completed, at which point the motion-type goes directly to 0 (Idle). So the issue isn't that the motion type resets immediately when the probe input triggers.
I was probing using just the X axis/joint 0 when I tested this.


I'll try and find out a bit more if I can.
