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

 

if I can take any two inputs and turn them into an MPG encoder in the HAL then could I just take two inputs from the EtherCat side?

I was thinking I would need to be running on an realtime thread to do encoder counting due to some timing issues between "listening" to A and B ticks.. But if the Pi GPIO can run on the Servo thread and 1ms is fast enougn, then it should be fast enough for the ethercat IO too right??

Hallo Uwe,

ich kann dir leider nichts zu Ethercat sagen, davon habe ich keine Ahnung, aber ein Laptop ist denkbar schlecht für LinuxCNC da es auf Stromsparen getrimmt ist und es somit zu Problemen mit LinuxCNC kommen kann. Man sollte nach der Installation immer den Latency-Test machen um zu sehen ob das System den Anforderungen gerecht wird. Ich selber habe 3 PCs ausprobiert, bis ich einen hatte wo der Latency-Test in Ordnung war.
Es kommt auch sehr auf die verbaute Netzwerkkarte an, es gibt Chipsätze welche mehr oder weniger gut funktionieren.
Wie es mit einem Raspi und LinuxCNC aussieht, kann ich für eine Fräsmaschine nicht sagen, aber ein Freund hat eine Drehmaschine (2 Achsen und die Spindel) und er hat einen Pi5 im Einsatz und es funktioniert.

Viele Grüße
Olli

Anything with the CAM letters in the product name/brand will do equally well for a 3ax. Starts to get picky at the 4ax simultaneous and becoming dangerously difficult to chose the right package for a 5ax.

For 3ax they all (most) do adaptive, rough to finish and comp nowadays. Pick any really...

Is ARCOK signal wired to plasma or derived from THCAD?

Hello everyone, when I was configuring the calssicladder, the number of corresponding physical inputs was always limited to no more than 16 points.

debug:
linuxcnc TPMOD=tpmod HOMEMOD=homemod EMCMOT=motmod
Note: Using POSIX realtime
Found file(REL): ./L510G_servo.hal
*** hal/components/xyzab_tdr_kins.comp setup ok

Shutting down and cleaning up LinuxCNC...


Due to my negligence, the bed used an unknown PIN-16... This was not caused by a software issue.

Apparently lost after upgrading to 2.9.4, can you check again, please?

I spent some more time on this tonight and after fixing some Python bugs and rechecking the wiring again, I hooked up my logic analyzer and verified that communication appears to be happening on the JTAG lines, I see mostly TDI with some responses on TDO, and clock signals appear to be working too.

I've done a quick drawing of how things are connected with the FT2232H Mini Module, as the pinout for the ports seems to differ from that of the FT4232H, and after checking the pins just to be safe, I see no data coming out of them, so I assume this setup is correct, matching port for port between the two modules.

I can run init95t and it seems like it attempts to program, and then cause a reset of the board, but the board goes right back into the same mode, with /DONE lit constantly, and no link lights on the ethernet:

./init95t  
Programming using Board Profile: Generic Board Profile Using FT2232H
jtag programming started!
JTAG Programming on ftdi://0x0403:0x6010:FT9MCMFR/2

Device ID read from JTAG: 0x00210A79
... finished with JTAG programming
waiting for reset
Old Name:  
Connection timed out

I'm not sure why it's not liking the file being programmed but I also attempted with the ethernet jumpers in various positions, and had no luck with that either.
Not sure if there's anything obvious wrong with this setup... I've attached a schematic of the wiring and the saleae Logic file as well as a picture of the logic capture. 

I should specify that the pin numbers used in the drawing are the ones from the datasheet and the ones on the JTAG match up with what is listed in the manual for that board.

im starting to think i might have something else going on.

with your point in the right direction and reading the documentation again, this time having had more exposure to terminology, i can find the modes and how to switch them. ive looked into the above three options and i think for now atleast i will run them as is, in torque mode.

Ive since double checked the servo drive settings and balanced it all so there is no movement when enabled. the drives also have a handy test option which internally feeds a +/-10v signal into the input for testing, this confirms the drive is set well and the motor functions very nicely. in fact the settings I landed on are near enough exactly the same as the remaining two untouched, as delivered, pulled from working machine (which much have been setup to run torque mode.

however when it comes time to have linuxcnc command movements, nothing is really behaving as i would expect, and i cant even begin to work through your above torque mode tuning process, because if i put even a 1 in the D field i get instant following error and a blip on the motor (P & I - 0), FF1 tried several 0 thru 1 ect), deadband 0.0001

ive confirmed its not runaway, because changing the sign on the scale makes that blip noticeable worse, presumably this is runway before the following error cuts it off.

the servo drive is now back in the same configuration it was when i began trying to incorrectly tune with tommys velocity mode guide so all info with reguard to some unstable movements with low P value, is still relevant, nothing useable though. Ive attached hal and ini files incase relevant.

given my struggles have quickly moved on from software installation into the seemingly typical noob hardware problems, if the mods would prefer to move this into a more appropriate channel that's fine by me. 

as always, thanks for everyones help, as a try DIYer, please know how much it hurts to ask for help and how needed that help is, if im asking
