If you change your home position then you will also need to change the limit values for the axis/joint in question.
If unsure please post your ini file.

I got it!

Thank you, after a bunch of messing with this I'd glazed over the 95/92 difference and didn't notice until you called it out.
Turns out my wiring was good, but I had the wrong file being programmed.

Here's what worked for anyone else who might have this problem in the future (in Linux, using a FT2232H Mini Module):

1. Download latest efinity software, extract to your computer. You need to register for a support account and then request a license, at which point you can download the software.
2. Download the 7I92T support software (contains the FPGA binfiles):  mesanet.com/software/parallel/7i92t.zip
3. Download the seveni92t.zip file  and extract it.
4. Connect up the FT2232H Mini Module to the 7I92T according to the wiring diagram attached. No connections to CN2 are necessary. Use 5V power to the 7I92T's power terminals, and don't forget to connect the jumper on the FT2232H Mini Module to USB bus power it.
5. Change the seveni92t.hex file's extension from .hex to .bit (The software won't accept a .hex file for JTAG programming)
6. Source the setup for the efinity software: $ source efinity/2025.1/bin/setup.sh
7. Set the board jumpers to Down,Down (to set the IP to 192.168.1.121)
8. Power the board on and flash it: $ sh efinity/2025.1/pgm/bin/ftdi_pgm.sh seveni92t.bit -m jtag
9. The /DONE light should go out and the green LEDs should blink in sequence as the board starts up, and ethernet should connect, now set your computer's IP to something in the same range as the board's IP (I used 192.168.1.120)
10. Use mesaflash to write the fallback firmware (this bin file is from the support zip) : mesaflash --device 7i92t --addr 192.168.1.121 --write  7i92t_16m_fallback.bin --fallback
11. Now flash your desired userfile to the user flash area: mesaflash --device 7i92t --addr 192.168.1.121 --write  7i92_<yourfile>.bin
12. Power down the card, unhook your connections, and power it back up, everything should function normally.

In my case I Just flashed a random user file, as once Pathpilot starts up it will automatically reflash the board with it's necessary firmware.

Thanks again for the help, hope the info I added is helpful if anyone else has the same issue.

Hello,I don't understand what's wrong. I think I connected the card to the ESP32 correctly, but I get an error message.

Greetings. At my work place, we recently acquired a CNC converted lathe running Knuth LinuxCNC 3.4.6.

There's a few changes we need to make for it to suit our needs. First was to set it so it would home near the chuck. I already moved the homing dogs and the limit switch orientations corrected the saddle direction so it homes out near the chuck as desired. I do understand this homing orientation is the opposite of what's commonly done on a lathe. The reason for this is the lathe is being converted into a grinder for urethane rollers. In this case we need to have the saddle home near the chuck to prevent having to move (or crash into) the tail stock so it can home every time we need to home it. We're replacing the chuck with a collet head with an internal stop for repeatability (provided our cores are to the desired spec, but that's another story)

I'm still familiarizing myself with LinuxCNC and despite my best efforts so far, I seem to have hit a wall. The issue I have is although I have it set to home safely near the chuck side, in the preview grid the position marker moves in the opposite direction. The saddle moves right the marker in preview moves left. Prior to setting XZ to X-Z it would try to travel off the grid altogether and soft stop would attempt to prevent it from moving beyond the preview boarder. You can see it in the image I attached how X & Z are positioned near the lower right of the grid. Is there a way to get the preview to place Z on lower left of the grid? 
Thanks in advance.

 

will try that, thank you!

Euch beiden vielen Dank schon mal.

Ich möchte die Frage nach dem Steuerungsrechner jetzt aber erst einmal in den Hintergrund stellen. Es macht für den Anfang keinen Unterschied, ob ich jetzt meinem Laptop oder den Raspi für die Einrichtung verwende. Und sobald ich eine lauffähige Konfiguration gefunden habe ist diese auch schnell auf einen anderen Rechner umgezogen.

Wahrscheinlich habe ich mir schlecht ausgedrückt aber mein primäres Problem besteht gerade darin, dass mir noch nicht klar ist, womit ich meine ganzen Ein- und Ausgänge verbinden muss. Ich kann mir mit "halrun: show pin" für die EtherCAT Komponenten und das Handrad die entspechenden Ein- und Ausgänge anzeigen lassen. Aber ich habe noch nirgends gefunden, wie ich mir die Ein- und Ausgänge des Regelungsthreads oder der Pfadberechnung anzeigen lassen kann. Damit ich eben für die ganzen anzulegenden Signalpfade (oder wie übersetzt ihr das "net"?) finde.
Gleiches gilt auch für die grafischen Oberflächen. Soweit ich verstanden habe, stellen die GUIs ja auch Pins zur Verfügung, um z.B. den Status eines Eingangssignals einzeigen lassen zu können.

Ein Beispiel anhand eines der Servos. Ich stelle mir den Regelkreis gerade so vor:
                 

Mir verschließt sich aber noch, wie ich das miteinander verbinde…

Schöne Pfingsten,

Uwe

See what voltage you get when cutting and how much it fluctuates, then set the ARC low and high to about 20-30V above and below.
Do a lot of tests till you get it to have cuts without interruption and no false OK signal at start.
And yes, the voltage will differ with thickness and feed rate, but usually under 10V difference on all of my machines (over 15 machines) for materials from 1.8mm to 6mm.

What card do you actually have?
(the title says 7I92T but you mention init95t)

Do you get the user (green) LED blink and Ethernet link lights illuminated after JTAG programming?

 

Look at this

ARCOK is derived from THCAD. My unit has arc ok output but the relay on the inverter board is not working so I'm using mode 0 for now. ark-ok-low is 60 and ark-ok-high is 200. Pilot voltage seems to be around 157 so maybe I could set ark-ok-high to 145 or 150. I've been testing on a scrap piece of 1/2" I had so not sure if the pilot voltage changes based on material thickness.

Redefine outputs from 20 to 32, or whatever you need.

Nice, glad you have such reasons, i've been out of commission for exactly 3 weeks now due to sticking my finger where it does not belong, it is astonishing how a messed up finger tip can limit the ability to work... or just brush teeth. This brushing teeth with left hand was absolutely hilarious for several days as i was shaking my whole body doing it! Got used to it though.
BTW, 3 weeks and still can not remove stitches as the swelling has not subsided sufficiently.

Thank you kindly PCW for your reply.

This might be a very stupid question, but how do I implement the link you provided into MesaCT?

Do Just download the last hostmot2.c and mesaflash.c files and swap them into the mesa flash-master folder?

Excuse my ignorance!

github.com/LinuxCNC/mesaflash there is a quickstart instructions at the bottom of that page to build and install mesaflash.

MesaCT uses whatever version of mesaflash that is installed.

Ja auf jeden Fall. Kein Laptop.

Thinkcentre tinys, Fujitsu esprimos, einiege Intel NUCs und wie erwähnt Raspberries sind geeignet.

Je nach gui reicht nen 4er raspi nicht mehr so richtig und es sollte ein 5er sein.

Ethercat oder nicht ist für die hardware (leistungsmäßig) quasi egal. Jitter ist bei 1ms Servothread gut in den Griff zu kriegen mit allen genannten obigen Rechnern. Man muss aber schon wissen was man macht.

Netzwerkgeschwindigkeit wie sonst für Mesakarten ist dir ja in deiner Konfiguration egal. Ich bin bei ethercat nicht fit, aber Guido hat in seinem Git was online was läuft...

I was completing and testing my new parameter subroutine for helical inside or outside contour ramp, adjustable stepover and x/y/z allowance finishing cut. Took the whole night to iron out some misbehaviour
