Hi, the remote was bought a long time ago, but I just took it out of the box and decided to connect it to my machine.
The lsusb command finds Device 031: ID 10ce:eb6f Silicon Labs
and I don't know what to do next?

I'll have to add float type status labels to a different dictionary to be able to set the precision.

A display delay is usually the CPU is maxed out and the display is always second to real time.

Glad to help, happy cutting.

As a recap and for reference:

0. Yes, the 7i92t can replace a parallel port, with the advantages of more functionality, more reliability and that it offloads critical processing from the computer's CPU. One caveat for my particular use case: the card needs an external stable 5V supply. 

1. In my case, I was connecting a lathe that has a DB25 connector and I needed the following signals: ESTOP (pin 1), XDIR (pin 2), XSTEP (pin 3, inverted), ZDIR (pin 4), ZSTEP (pin 5, inverted) and SPINDLE ON/OFF (pin 16). The following is the correspondence between the DB25 pins and IO Pins in the Mesa card:

DB25 => 7i92t
01   => IO Pin 000 
02   => IO Pin 002 
03   => IO Pin 004 
04   => IO Pin 006 
05   => IO Pin 008 
16   => IO Pin 005 

IMPORTANT: in computer parallel ports, pins 18 to 25 are GND pins. Jumpers W1 and W2 on the card must be set as pull-downs to GND by putting them in the down position. 

2. A firmware needs to be selected that matches the requirements. For that, you need to download the support files for the card from mesa. I got mine from: www.mesanet.com/software/parallel/7i92t.zip. After unzipping the file, navigate to the hostmot2 directory. After inspecting the format of the .pin files, I used the grep utility to find the files that matched the step generator pinout I needed, like this:

grep -il " 3.*4.*stepgen.*step" $(grep -il " 2.*2.*stepgen.*dir" *pin)

That grep is not perfect, I checked the 3 files manually and the firmware that was the best fit for my pinout was the 7i92t_benezanx2d.bin (the one that corresponds to the .pin file)

I uploaded the firmware to the board using the mesaflash utility.

3. I ran the pncconf utility and created a new configuration. For the card discovery utility to be available, "Show Advanced Option Pages" in the "Start" page needs to be enabled. That utility reads the pinout from the firmware when you get to the "Mesa Card 0" page.

The machine is running well, I made mistakes like disabling the "Include spindle" setting on the "Base Information" page, that's why the spindle was not turning. For the motor setup I only needed to change the scale, which was simply the number of steps per mm. I also changed maximum speed and acceleration, and the hold times according to the configuration I had from when I used the parallel port.
 

Well, one motor driving multiple axes sounds like it has to have clutches. To use modern controls, you need to drive EACH axis with a dedicated motor. It will make a MUCH more versatile machine.

+24V

Note that those are all Linux questions, not LinuxCNC questions
so perhaps better asked in a general Linux forum.

is this a static error? ( error when not in motion )

If so and you already have as much P term as you can set  while
remaining stable, you can add some I term to eliminate the static error.

If it's a dynamic error ( error when in motion ) I would have to have a
halscope plot of the error to see whats going on.

What about removing the package from the image file?

I doubt you have a issue with the kins probably an issue with the setup or measurements. Scaras are sensitive to incorrect arm length measurements.


Read the docs for scara kins and make sure your ini is setup correctly. If that doesn't work post them here

Hi I trying to make a cnc control panel with touch screen and tactile switch and communicate to control box via EtherCat.and to my
unknowledgeable I thought a modern mini pc multi core ddr5 would be better to run high speed real time instruction and purchase MSI
cubi NUC 1m turn out a 8 core cpu is no good with real time kernal and worse an onboard vga is MSI SOC proprietary driver which
bookworm not support and general intel driver is not support either only for the late 6.8 kernal support it but it bring tons of latency.So I decide to shift to raspberry pi 5 and then see a uconsole for raspberry cm5 and it NVME support.
So my question are follow
Does Linuxcnc support raspberry CM5
Does Linuxcnc Support CM5 EMMC memory
Does Linuxcnc support NVME SSD
Does Linuxcnc support CM5 carrier board
Does Linuxcnc support touch screen with SPI connection
Thank in advance

As far as I understood not. I thing the TOT variant had a central motor which drove the axis via some sort of internals. (maybe I remember wrong).

Hello,
After adjusting my Z-phrase for homing, I'm looking to gain some prediction on the positioning of my.
I have a 2000 puls quadrature encoder, which gives me a precision of 0.04 mm. However, I can't get within 0.15mm.
How can I get as close as possible to the maximum resolution of my encoder?

Thank you
