Servo Spindle with velocity AND position mode for Toolchanger?

Category: Advanced Configuration

hi andy!
i think the right way is to use your carousel.comp.

but i have no idea how to link this up... its complete new to me and i need help to do this.

i try a little bit.. but if i want to go from pocket 1 to pocket 2 i must count a hole 2 times in a spinning gear disc.

i dont know if INDEX is the correct mode.. i dont want that ou think i am stupid... but.. can we do this together? or is there someone who can help me?

thanks

Unwinding Rotary Axis for Homing

The spindle mount is just something I came up with and made.  Right now it fits a cheap air cooled 80mm 2.2kw spindle, but I can fit a 100mm diameter spindle if I need to.  I machined a hole in the side of the spindle to feed the wiring out of and through the center of the side bearing.  I hope that will save me from tangling up the wiring.

Help : Layman configuration for Raspberry Pi 5, Linuxcnc 2.9. and Mesa 7i96

ahh.. as explained in this thread, you have to press spacebar to actually select the locale in the sudo menu-config (ha ha) :dry:

by typing locale in the terminale, the newly set locale can be confirmed. I have fixed the locale issue now.

so back to the interface settings and network manager.. i still need help there. Thanks again to all!

Many users encounter issues when operating SCARA robots in real-world scenarios, including joint following errors, motor jolts, joint value shifts after homing, and the robot's inability to operate in negative space. These problems often stem from inaccuracies in the inverse kinematic equations. For example, modifying the home position to 30 in the SCARA configuration file (available at: github.com/LinuxCNC/linuxcnc/blob/master...vial/scara/scara.ini ) can cause joint 1 and joint 3 values to change after homing, leading to joint following errors or motor jolts.To address these issues, I created a modified version of the configuration. This version corrects the inverse kinematic calculations and includes adjustments to how the Z-axis is calculated for my specific use case.

Once you have networking setup you can configure your Mesa card as you would for a normal PC, there are plenty of threadson the forum regarding this subject, there is nothing particular to the RPi platform in this respect.
 

i have run into a locale issue. what should be my locale set to? i am based in Germany. 
from Locales by Behai, i set up my locale as en US.UTF-8 UTF8
but the issue persists.

and as i understand, you suggest to comment out the following lines in the interface file? correct? or will i also have to edit something in the Wpa supplicant? (once again i would prefer doing it through the menu-config)

with network manager installed, i cannot reach the network interface file like earlier. 
i tried to use
> sudo service NetworkManager stop
but then i cannot enter the network menu in the sudo menu-config anymore

to edit the file in the etc/network folder i cannot save whatever i have edited. and i would really like to edit it through the sudo menu-config rather than messing up any files manually through the filemanager

whats the go around?

If it's not working just look up Changes by Black Sabbath on YouTube.
Started playing when I clicked the link a minute or so ago, but Big Brother might be on to us. So we better cut down talk about DIY fusion weapons.

Remove the setup for the network you want to manage from the network file.
Leave the wired connection in the network file and use network manager for the wifi. I turn the wifi off whilst running a job.
May help with latency, stops Bad Guys from messing stuff up.

Reasons to DIY build a 3D printer

Category: Additive Manufacturing

Personally I would only opt for ballscews on the Z axis on a bed slinger.
But in all honesty before knocking the Ender 3 use the machine, spend some time setting it up, stiffer bed springs or as the current trend solid silicon spacers. The printer itself is only part of the equation, the secret to a good print, we're talking functional prints, is designing the CAD model with thought as to how it will be printed. Dealing with shrinkage on holes, understanding that 0.1mm accuracy is the best you can expect. What works for my Ender 3 may not work for yours for nailing hole dimensions, then throw the type of filament into the equation and things change again.
There's a reason the Ender 3 was a popular choice as an entry level printer, it Just Worked out of the box.
Teaching tech is a good channel on YouTube, Michael won't piss in your pocket and tell you the sun is shining. I've found him to be honest in his opinions and quite a knowledgeable chap,and no I'm not being biased because he's a fellow Aussie. As we say he knows his shit, plus he keeps goats.

Hello Sir, i did read about that in the wiki.debian.org/NetworkManager
how may i make it visible and editable through the network manager. specifically the wifi connection.
also as i pointed above, i tried to make a new wifi connection to my mobile hotspot, but as you can see, i cannot connect to it or use it.

If you setup a network interface in the interfaces file,
that particular interface is no longer managed by
the network manager.

quick question, why does my network manager look like this? im still connected to wifi, and also have the connection to mesa card, but those options dont show up. i also set up a new wifi connection 1 to a different source, but im not able to switch into it or make it run.

Generally only suggested for Intel NIC, RPi uses a Broadcom NIC.

I would also recommend the zswap mod if you intended to use an interface other than Axis, there is a reference to that in the index.

Once you have networking setup you can configure your Mesa card as you would for a normal PC, there are plenty of threads on the forum regarding this subject, there is nothing particular to the RPi platform in this respect.
