Echo does not work, try this
forum.linuxcnc.org/9-installing-linuxcnc...master-branch#324711

For the T43 use this
www.linuxcnc.org/iso/ubuntu-10.04-linuxcnc3-i386.iso

That was the one! AXIS is now working. Learning how to tune it now.

Maybe not.. now it stops at:

cnc@raspberrypi:~$ sudo echo "deb buildbot2.highlab.com/debian/ bookworm master-uspace 2.9-uspace" >> /etc/apt/sources.list
bash: /etc/apt/sources.list: Permission denied

Ooops, I don't think this will work on the Pi5

Sorry, the forum broke it.
I edited the post above

Perfect, I really appreciate your help. 


Thank you.

Hi guys!

New user here with limited knowledge. Trying to convert an old mill, have a rpi5 and a 7i97T for the job. Planned to use MesaCT to help me with the start of the config, but there is states the 7i97T needs LinuxCNC 2.10.

I've already installed the "Raspberry Pi 5 OS based on Debian Bookworm " from the website, which i'm now trying to update using this post. No luck so far for me!

seems to fail from;

sudo cp -r /etc/apt/*.* ~/aptsudo wget buildbot2.highlab.com/buildbot-archive-key.gpg /etc/apt/trusted.gpg.d

returns;

cp: cannot copy a directory, '/etc/apt/trusted.gpg.d', into itself, '/etc/apt/trusted.gpg.d/trusted.gpg.d'
cp: cannot stat '/home/cnc/aptsudo': No such file or directory
cp: cannot stat 'wget': No such file or directory
cp: cannot stat 'buildbot2.highlab.com/buildbot-archive-key.gpg': No such file or directory

Thanks for the reply. So I do the testing with my T420s/x220.
(I'll skip the testing with the T43 as I like to use the complete LinuxCNC Distro instead)
Mesa and TB6600 are ordered. As soon, as I get the material, I'll share my confusion with the wiring
Aan when I have some running setup, I'll post in the laptop topic (that's where I got the idea with the T470 touch)

Hello everyone.
It works now but i have another problem. My machine have 2 motors for the X axis. When i click on the X+ or X- button only one motor turns (X1). when i click on the Y+ or Y- button it's the other x motor that turns (X2). Any ideas?
Thanks in advance.

The sheet roll-feed is done by 2.2kw induction motor that has reducer driven by vfd.
Motion is not accurate can do a slight backwards movement to roll back the sheet.
There is an encoder-wheel that is on top of sheet that calculates length.
Movement is not so accurate but measurement of sheet length is very accurate because encoder measures directly the sheet with wheel and nothing that introduces backlash etc..
From g code can call hal component that will do the unrolling after cut then pause unroll again continue cutting and go on?
Can with a camera detect old cutting x-y and re-set G54 x-y zero and next code cuts from where last code stoped?

Hi Mark,
I watched one of your Youtube videos again on the wonderful tool made for you by the guy in Malta. Nice to have friends like that.
A lot of good comments there. But I don't think you can add photos to the comments. So I'll stick my nose in here instead.
It's and area that makes my head swim. But it seems to me that the method is really just about making the quill square to the table. The vertical head on our machines only rotates around the Y axis, but on many Bridgeports it can also  rotate around the X axis. In that case you could use the device to make the quill perfectly square to the table. But you could also tilt their table to any angle (some can do that) and tilt the head to be perfectly square to that using  your device. Then you could use the quill to drill nice holes. You might do that to fit an oversized object perhaps? But it would do nasty things to the drill if you moved the knee while drilling. An extreme case example. Feel free to call me and idiot if I'm seeing it wrong.
My machine has that nice taper roller grinder style quill, which has a slight preload. So no looseness, but it will still have non repetitive run-out errors due to the various manufacturing errors in rollers etc.
On my machine you can see there is a detent knob on the head tilting. It clicks home at zero degrees on the tilt dial. When I put my dial clock on it then and swing it I get almost perfect alignment in the X direction. Big surprise! The head rotation clamps just like yours but with 4 bolts. You can see they scribed the zero mark on the head after they did the alignment by the missing paint.
I've added a photo of when my rotary table is removed. You can see the 8 bolts that clamp it on (so I don't misplace them). There are keys on the rotary table that fix the tilt when it's assembled. You can see it's not a dovetail system. I suspect I could align the table sag by removing that array of bolts along the bottom and putting shims between that X slide and the bearing rails.

Cheers,
David
 

OK, thanks. I'll give it a try. I'd like to add a button instead of macro buttons in qtdragon. thanks in advance.

It's not necessary, but if you have an encoder it's useful for verifying spindle rpm. The encoder signal does need to be connected in Hal for threading.
