LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

Thanks for solving the diff issue, it has given me a real headache.

The Compile button is enabled now and I am going to check, if it compiles etc.

By the way, Tangbob config.json contains a plugin "blink" mapped to pin10, which is not available on the Tangbob FPGA board (not wired on your PCB). Furthermore, pin10 belongs to the bank 3, which works with 1.8V (not 3.3V) causing an error when placing in the toolchain.
(I used the generated files from your program in the Windows Gowin IDE for running the whole process. It gives me more control what's going on during the processing)

SPI should work though a Efinix specific top level file would need to be
made from the Xilinx source.  Efinix tools don't automatically
translate "Z" types into tristate pins so you have to export the signal
_and_ enable pins from the top level file. Note for the current SPI source
(GCSPI) The SPI clock must be routed to a FPGA clock pin.

Any package is OK

Hello,
i finished with my linuxcnc setup and now i have some trouble with the accuracy.
Im using qtDragon and the newest version of linuxcnc (2.9.3 i think).I home my maschine first and after i send it to the G54 g0 x0 y0 z0 and the machine is going there but not reaching exactly the 0 position.
anyone could maybe help me or explain me?

I've been gathering and planning quite a bit. My motors and drives came in yesterday and another batch of goodies should be here in the next few days.

I'm still working on my finished plan but have a much better idea of how thing will look coming together.

But with a floating head with a magnetic breakaway and about 5 inches of Z travel i came up with this so far.

qtvismach, a axis toolpath

Category: Qtvcp

length = hal.get_value("hor_pos")
length = (float(length) + 115)
mat = Box(60, -30, -30, length, 30, 30)
mat = Color([0.4, 0.6, 0.2, 0.4],[mat])
mat = Rotate([mat],0,45,0,0)
mat = Translate([mat],0,0,0)
mat = Color([1, 1, 0, 1],[mat])

This is how I build a material element mounted in a lathe.

For now, only the material length is determined automatically, depending on the position of the lathe tailstock.

After the first simulation run, the material dimensions are drawn correctly. The problem is with rebuilding the dimension after running another ngc file with different dimensions.

I tried using HalToolCylinder and HalToolTriangle in various ways, but I must be doing something wrong

Xilinx Setup to edit config for 7i92T

Category: Driver Boards

Thanks PCW and cornholio for your pointers! 

I would really want to try a custom firmware as the card will interface with two pre-existing connectors / controllers within a very tight space - adding a DB25 cable which reroutes the ports will be an absolute pain 
File Attachment:


I have now Efinix loaded and running, and I have found how to load the 7i92t-hm2 project (I assume from other forum posts that the 7i92t25 is for larger projects and so not applicable for me). I'm not able to find a pointer as to where to edit my pins? I read that I need to edit seveni92t.peri.xml but that file looks daunting: how I find which pins (of the two ports) are meant?

Also, thanks for the pointer regarding toggle: I have amended my notes, does it work to have just one Step, or do they need to come in step/dir pairs?

Problem solved! The solution was a clean uninstallation and then a complete reinstallation.

Category: EtherCAT

Hello

Thank you for your comments, please see below the updates.

I modified ethercat-conf.xml -
It looks that there is still no connection between XML and linux.I ran the command
sudo dmesg -wH
to monitor system logs in real time. (dmesg_wH.png)
  • The white area at the top of the output corresponds to the period when LinuxCNC was started.
  • The logs below show what happens when the LinuxCNC session is terminated (after clicking "Exit")
The same has been proceed for: sudo dmesg | grep EtherCAT

I would appreciate your support!

thanks MirkoCNC,

the -p stands for preview, which should be omitted when generating correctly (fixed in dev branch)

the diff command should be replaced, preferably with a python lib, as it does not exist under windows

EDIT: diff is now replaced with python code

Hello everyone.
I am trying to connect an MPG encoder, but it does not work, it does not always count to 0. I connect it to an Arduino Nano in pins 2 and 3 that are the pins with interruptions.

I have modified in the .ino file:
#define Quadencs 1;
Encoder Encoder0 (2,3); // a, b pin
const int quadencsig = {2,2};
const int quadencmp = {4.4};

In the .py file
Quadencks = 1
Quadenck = [2,2]

Nope, not implying anything, i just liked the name and wondered how the hell did they get it registered as it is the equation for energy

A Couple HostMot2 / Efinix Trion FPGA questions.
  • Is SPI a option or only Ethernet & PCI at present? I did not see a spi _efx.vhd but I may have over looked it. 
  • Any reason a T20Q144C4 could not be used instead of the T20F256C4 with Hostmot2? I feel like I may be over looking something obvious for the sake of solderability while perusing the source files.

Have you looked at HalToolCylinder and HalToolTriangle ?
These change the shape of an object.

Can you post the material object building code?
