Spindle speed?

Category: Basic Configuration

Alright. Finally back on this project. The control appears to come from computer to a mesa 7187 to the VFD. The forward and reverse commands from the board go into STF and STR to command direction. Pins 2 (input) 5 (analog common). In forward the voltage ramps up and down as commanded through the gui and shows rpm in the bar. But in reverse the voltage to the VFD stays the same. If I switch forward and reverse command wires in the VFD they simply act in opposite. This eliminates the VFD as the issue. I need to find out why Linux isn't controlling the voltage to the VFD in reverse and also why it's not displaying reverse RPM in the GUI.

Glad it's working, I just automatically applied the patch.

The patch docs don't mention any project file
incompatibilities but that's what seems to have
been the issue.

Hello PCW,

Your advice was right. I applied the 2025.1 patch an everything went as expected.
Efinity 2025.1.110.3.16 works fine on ubuntu 24.04.
I can edit the files, change them and flash my 7i96s wit the expected result.

Thank you very much

Surfacemap Z compensation with Probe Basic was created by --Matt--

Surfacemap Z compensation with Probe Basic

Category: QtPyVCP

I've got linuxcnc 2.9.3 installed on Debian 12 Bookworm with prempt RT kernel. I followed these instructions to install Probe Basic via apt.

kcjengr.github.io/probe_basic/stable_quick_start_apt.html
(Actually, I've tried both stable and dev versions).

I'd like to try Z-compensation via external offsets and was hoping to use surfacemap to automatically probe an XY grid of heights. (This is for PCB engraving on a mini mill).

Surfacemap is apparently implemented as a Probe Basic user tab:

github.com/zmrdko/01_surfacemap?tab=readme-ov-file

In the probe basic probing tabs I've had a few troubles with the entry boxes in the UI not accepting values. I think I managed to fix this problem by adding missing variables into the parameters files.

The surfacemap user tab seems to be giving me similar problems but I wasn't able to fix that just by adding parameters.

Has the surfacemap code perhaps been broken by the latest version of probe basic? Or had it perhaps never reached a fully working state?

Any other options for automated Z-level probing and compensation?

Ironically I came back to this thread to recall what was said about the USB/CAN upgrade.
I still haven't finished my 2.4 because of having the X1C going most of the time
and hoping Voron Design would have had the Phoenix released by now. Oh well.it's
always something.

Ok, so here is a sequence of halcmd show all outputs, stages reflectiing my original description of operations.

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

I have poured over the Remora documentation but can't find the syntax (if it exists?) for the config.txt to set up an input on a Remora supported controller board as an analog input. Is there a way? I have gone over all the config.txt files that I can find and they all seem to be variants of 3d printers and they have thermistor specific inputs (which are analog I realize but the only general signal inputs seem to be digital. Any help/hints/links other appreciated. TIA

Scott. Please forgive me if I am using the forum improperly. I have a project that I would like to base on RPI5 and Remora on a Bigtreetech board. I have read all the Remora documentation and studied all the config.txt files in your github. The question: can Remora support a general analog input (say to an ADC pin on the supporting processor)? In the limit, can I repurpose one of the thermistor inputs or are they dedicated to thermistor processing? TIA.

Good spot,

I need to refresh my g-code understanding, but I am scratching my head as to what I was trying to achieve when I made that mistake. And also why much of the time it actually works fine (more so with an earlier version of linuxcnc).

I will do as PCW suggested first, then see if cleaning up that bit of code makes a difference.

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.

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 was created by Cysign

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.
