aliexpress 7i92 have anyone used this card, how can use,https://www.aliexpress.com/item/1005011667901833.html?spm=a2g0o.detail.pcDetailTopMoreOtherSeller.1.7ccfDf5dDf5dYi

cheapen hahaha, aliecpres card cost 40-50 $ and mesa genuine cost ower 100 $ lot different price, hobby users not have money waste ower 100 $ only small card, need be lot lot cheapen can buy hobby cnc card.
and second, why waste lot money buy etc 160$ card if all same can buy aliexpress 40$ lot different price and stupid if waste lot money if not really need.

Hi grandixximo,
Congratulations on a viable solution to this long standing gap in Linuxcnc implementation.
I was going through how you have taken into account the kinematics in userspace for planning which is needed for kinematics bounds checking.
I also see that you have made the relevant changes in the kinematics defined in src/emc/kinematics/* files.
There is another set of switchable kinematics defined in the src/hal/components/*.comp files (method made viable by David Muller / aciera on this forum). For example xyzab_tdr_kins.comp, xyzacb_trsrn.comp etc.,
I somehow find the idea of implementing the kinematics as a loadable .comp module compiled by halcompile very fascinating and useful
Is there a guideline on how to transition those kinematics also to this new setup?

Is there stock available for purchase of the height sensor?

A couple of days ago, I saw 1 in stock, but when attempting to purchase, it said out of stock.

Epoxied electronics sure are hard to extract. I have had some success using a small butane torch or a heat gun to soften the epoxy with heat. Some kinds of epoxy turn rubbery an can be carved out in small bits with a knife while it is hot. But that is messy. It is too easy to burn it up or start a fire. Plus I end up with blisters on my fingers from working with the hot stuff.

Take care and have fun!

but normal need use WHITOUT this expensive hat , only gpio pin out and shift level converter can use 3,3V gpio pin to out 5V and traight to driver step and dir and enable pin.
how this made if ewer newer not has understand anything code nd not understand what need doing code, understand only good all hardware how connect and build,
i have rpi4 and SD card have linuxcnc rpi4 image, working and boot ok, (whit HDMI display) but not boot whit pi hut mikro HDMI to vga cable.
how make this gpio pins can take out gpio pin to driver DM556. were can download setting hal and ini file or what need add to rpi4, normal peoples NOT can understand and write hard code to rpi, hal or ini or what possiple need doing, not know.
i just buy rpi4, paraller port BOB, cheap chinese 10$ board, encoder, rotary SW, shift level converter modules, 3,3V to 5V, all buttons, DM556 drivers, nema 23 470 OZ/3Nm motors, lot hardware but not can made code anything.

help need send to me files what need copy and paste to rpi4 linuxcnc and were folder need add. not know were and what and how.

I have not tried connecting a BOB to a Raspberry pi. I think it could work but it will not be easy. You will have to write the hal and ini files.

How will you connect BOB to the Raspberry pi? The connectors are quite different.

If you could use your BOB connected to a pc that has a parallel port that will be a lot easier. I might be able to help. Then you could use stepconf to create your configuration.

Youtube isn't all bad. As a newly minted but not yet monetized Youtube Partner, I got an email from them today reminding me of the copyright match tool I was now allowed to use. So I turned it on in YT studio and low and behold there was a match where somebody made a video using 90% of my content. A video of my Spaceship Plasma cutting a part (well lots of parts). They had been selling off my video for  four years!

I decided to play nice and asked YT to serve them a 7 day take down notice, instead of an immediate takedown.

Last time I had something similar was a large company using my registered trademark running Google ads for my product! That time I had to pay a specialist IP lawyer to issue a takedown request which cost me quite a few $ and Youtube is doing it for free!.

Hello,

I had a similar issue where I had to skip the grub boot installer step.

I found a solution is to install like normal and skip that step, then launch the usb boot drive live. From there, I had to mount the efi drive partition (/dev/sda1 I think it was). Then I went and renamed the Debian directory in EFI to boot and the grubx64.efi file to bootx64.efi and then everything booted fine.

I was doing this on an old Mac so it could have been a little different.

Its not possible to install Debian without an internet connection (hardwired is best) The Linuxcnc installer depends on internet (It uses the Debian Live INstaller). Try offline at your own risk

What pins do you mean?

If you run:

mesaflash --device 7i96s --addr 10.10.10.10 --readhmid

it will print the 7I96S's function (stepgen, pwmgen, encoder, etc)
terminal block pin numbers.

(replace the 10.10.10.10 with 192.168.1.121 if the 7I96S is jumpered that way)
 

Just checked 7i97t_7i74d.bin

md5sum=

4130ebee623115267327c166f8da9d39  7i97t_7i74d.bin


All encoders work, 7I97 sserial (0) and all 7I74 sserial channels (1..7) work as expected

 

I have only used firmwares from the Website. I also know that i only need a 7i97t with 7i74 firmeware. In the file there are a few firmwares with the 7i97t_7i74 Name. So the 7i97t_7i74d.bin is the right now?

Tomorow i will look further in to it.
And why the encoders arent counting.

might be a dumb question I have a 7i96s how how do you no where PIN numbers locations. I'm in the pnccofig it says pin # xx  but where is it on the board ?

This is the plan. Keep in mind, all who follow, that if you finish the installation completely offline-no internet access-your Debian package sources files will be empty. You will have to create the .sources file, or when you do sudo apt install you will get "could not find" and when you do sudo apt unpdate it will run through the updates and say there is nothing to update.

So pll-error remains 0 for me. App phase hovering between 9800 and 10500

What i did notice, i had all 3 axis vibrate like crazy upon first Launch today. Rebooting lcnc fixed that.

Edit: did another power cycle. No Vibration but sudden clunking on all 3 axis again
