Not much progress made on plasma table today but started welding up a horizontal sheet metal rack based on lazer bros plans. I've been storing verticaly and it's a pain and dangerous to set the sheets down on the table like that. I've had my guy cleaning the rails on the plasma table using a wire wheel then when I set them all up going to try to stone any high spots. Do you know of any good literature to study up on for setting up these gantry style tables? Specificly in keeping the rails parallel and level. I'm sure there's tricks with lasers and string bobs etc.

Had some time to play around with the FPGA again. The new W5500 arrived last week, but I had not enough time to wire it up. I was really surprised. Once I flashed it with the right IP, I was able to ping the board. Started LinuxCNC and it worked! Magic!  Used the wiring from the example before. Will need to change a few things as it seems the logic is inverted and continue to wire up the level shifter and connect to my stepper driver.
Can this error message now being ignored?

Unexpected realtime delay on task 0 with period 1000000
This Message will only display once per session.
Run the Latency Test and resolve before continuing. 

Thanks,
I will check that out.

yeah i compiled most of them but i havent tested it yet, ill compile the rest this weekend

After reading the manual again, it looks like there shouldn't be any LEDs on. I cleaned everything up and plugged it back in and now Mesaflash can see it again.

Nice, thank you for reporting back.
Now you know if something happens later that you can count on support here.

Hi ChrisI
Have some fixes qtdragon .
1. Fixed wrong button size in qtdragon_hd g54
2. Fixed button qss file for qtdragon
3. The "systemtoolbutton" button should be removed from the "button_response_list" list in the support file, because in auto mode during work, it is not active.
What is the function of the red frame in the gcode field?
If I click in MDI and a red frame appears, it is not possible toremove it later. 

scotta thank you,I'll try to understand, I see that you explained the initial steps in a nice and photos way, so I'll see how far I'll go..thanks

Getting back to the topic of Remora SPI, I have pushed some updates to the repo to give command line options to specify the SPI number, CS number and frequency of the SPI interface for the RPi 5.

loadrt remora-spi SPI_num=0 CS_num=0 SPI_freq=20000000

Default frequency is 20Mhz, which is happily running on my Octopus, with Cakeslob's latest compiled firmware, without communication errors.

We'll need to update all the firmware to the latest. Thanks for your patience, but if there is a priority please let us know.

Best to start with
www.forum.linuxcnc.org/18-computer/44828...c300-ec500-cnc-board

The board you have is an STM based board, which was the first Ethernet board to be supported. So the early part of the above thread covers the development and firmware installation stuff.

Greetings,
I have two nvem cards, I can't read all 80 pages of the post related to the implementation on linuxcnc, can you explain step by step the procedures of a short way to implement them on linuxcnc, in the shortest possible terms for those of us who have very little knowledge about programming. thank you
   

@CObra
thank you for your answer.
With help from the NUM support the NUM 1040 controller is now working again and i will not change to LinuxCNC at this machine.

If anybody have problems with this NUM controller:
This NUM 10x0 Controllers have a problem that they sometimes lose files (some machines every year some never in 30 years). If you have a backup (you can get one from SCM) a NUM technican can get your controller working in one hour and he will shows you what to do next time. But he must be in from of the machine because it is not so easy the get the connection.

Good thought.  I'll check tonight - I sort of made an assumption that the previous owner checked that, but that's probably not a safe assumption.

I checked the jumpers, they were all set to Low (default)  I set the jumper to high and it didn’t make any difference.  

There are no red lights, just green and amber.  

I was told by the previous owner that half of two of the 7i40s don’t work.  This joint is on the working half of one if those cards.  I’m wondering if there might be more wrong with that card than I originally thought.   

The next test I guess is to swap two joints.  

Do you get overcurrents on the 7I40 (red LEDs blinking)?
Also are the 7I40 current limits set to the high range?

I attached a digital angle finder to the axes, moved it a specific amount (45 degrees), calculated how many encoder steps were read, divided by the number of degrees and entered that number into the joint config in the ini under encoder scale.   The numbers I entered were only a couple encoder ticks off from what was already there.

Is there some other spot to enter the encoder resolution/scale/ppr?

I am unable to find any documentation whatsoever on the specs for the encoders: Tamagawa TS1902N117 or TS3083

I am also considering swapping 2 of the joint connections to see if the issue follows the daughtercard.
