Custom PC build for my brothers company and more

Category: Show Your Stuff

New builds for a dentist, needed 3 of proper PC's for the new offices, but insisted on plain simple cases, will have to switch of the LED's before sending them as he might have a heart attack! :)
They do boot fast though, very fast:

Will do the boot test on Linux as it should be even faster...

I will need an ice cold shower if they call and say they can not ship it due to ....reasons!!!

Had several cold showers back then as even their CEO called me to justify their f@kin mistake, aft6er about 20 phone calls i had enough. They did offer to send me the motherboard that the EAN number was listed instead, but i said no.

You don't need "20 years of Linux behind you", get rid of that way of thinking. All you need to be able to do is follow instructions, minding syntax and not taking shortcuts, and be able to relay any error messages without leaving anything out. It is also to follow any links in replies, it saves those that reply having to repeat any info.

Oh and mesa wouldn't sell you a product that is deemed to work with Linuxcnc that doesn't .

Did you look at the download PCW attached, I think it was a simple config to get you going.

Upgrading mesaflash from the GitHub page may help with your issue .

Hey Guys,

I was quite busy that week so i didnt get much work into it but here is what i got at this point.

On left down corner you can find a Vakuum button that allows you to switch Clamping variant between a vice or something like that and vacuum clamping. It opens the PopUp on the right side, there you find 4 displays for 4 vacuum plates, your able to switch them on or off depending on how large your workpiece is you can work with 1 or with all 4. The Main Slider down in the middle allows you to set the needed pressure. Every plade is moitored by a single Pressure sensor on a beckhoff EL3124. If the pressure gets lower then the main slider value the system goes immediately in E-Stop mode to provide serios accidents. The main slider may gets removed after i made some experience with the system.

How do I lubricate correctly?

Category: Milling Machines

Good info.
I used Nylon tubing in the past. I think. Whatever it was has been holding up well. I'll look into Kynar.

What are the compression fittings you are using on the trucks? That is usually the more difficult part to source due to the odd pitch of 0.75 on some LM blocks.

Push to connect fittings are fantastic except for some that grab the tubing without a proper release mechanism. Meaning the collar that gets pushed in doesn't slip over the teeth to release causing tubing to become shredded during removal. That can contaminate critical components. I wanted to mention that as I recently went through that with cheap fittings. 

For a lathe I would need 10 remote ports if direct fed like on your setup. That might be okay.
Equal length tubing may be a solution to avoid metering units if running it off a manifold. Any experience with that?

Spindle position in Axis does not reflect spindle position on machine in space

Category: AXIS

The issue seems to stem from how AXIS interprets the machine's home position relative to the bounding box. By default, AXIS assumes the origin (0,0,0) is at the center of the workspace, but your machine's home is at the top front corner. Changing the min/max values in the INI file shifts the bounding box but creates new problems with axis limits.

To fix this, you need to adjust the **HOME_OFFSET** values in the INI file for each axis. These offsets tell AXIS where the machine's home position is within the bounding box. Set the offsets to match the actual physical home position (e.g., top front corner). This should align the GUI spindle position with the machine's real spindle after homing, without affecting the axis ranges or soft limits.

issues with isolcpus

Category: General LinuxCNC Questions

I cannot get the isolcpus command line to take effect.  I have set the grub to the following:
savedefault
load_video
insmod gzio
if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
insmod part_msdos
insmod ext2
search --no-floppy --fs-uuid --set=root a08bfa77-56e1-4ee2-a80a-ccc22b8725cd
echo    'Loading Linux 6.3.0-rt11-linuxcnc ...'
linux    /boot/vmlinuz-6.3.0-rt11-linuxcnc root=UUID=a08bfa77-56e1-4ee2-a80a-ccc22b8725cd ro initrd=/install/gtk/initrd.gz 
echo    'Loading initial ramdisk ...'
initrd    /boot/initrd.img-6.3.0-rt11-linuxcnc
GRUB_CMDLINE_LINUX_DEFAULT="isocpus=3"

And have changed the last line to 0,1,2 to 0, to 1, and to 2 with no effect.  The histograms show 4 cores no_isolcpus.
This is an intel i5-6500t.
Any ideas?

Linuxcnc 2.9.4 and Mesa 7i97T

Category: Installing LinuxCNC

But will it make any sense at all to try to configure the setup as long as I get an “unsupported board”

A little about the background for the project.
I have over time -as a side business - made several retrofits of older (woodworking)cnc machines
Normally I change the driveline to new hybrid steppers controlled by a plc with a control sw developed by ourselves (or in a few projects Mach 3&4), but in this project I have a huge 7ton Homag with very powerful Rexroth motors and drives where i have modified the drives to analog control.
Therefore I went for a LinuxCNC and a mesa 7i97T.
I accept there is a learning curve but it has been far more complex than expected.

I’m surprised about how many YouTubes are found about “LinuxCNC as easy as Mach3” a statement I have hard to believe unless you have 20 years of Linux behind you

Very good work!
I've started testing.
I've noticed that the track speed is very low with G2/G3, but significantly higher with G64 Pxx.

More tomorrow.

How do I lubricate correctly?

Category: Milling Machines

Here's what I came up with for my Mill's Y-axis saddle.  Much simpler than running grease/oil lines to a central lubrication pump...make them just long enough for easy access.
  • Hose is Kynar (PVDF), I believe 4mm OD
    • any fluoro-polymer hose/tube should be fine (PTFE, ETFE, etc), stay away from anything else.
  • Fittings are just cheap air-hose push-to-connect (same as 3D printer filament tube size)
    • The cheap push-to-connect o-rings will likely fail after some years, but it'll be obvious when it happens and I have a dozen or so spare fittings
    • Drill out the PTC fitting to remove any unnecessary constrictions (it's surprising how small the ID is)
    • The fittings on the actual trucks are compression w/ferrules, so no o-rings to worry about
  • Manifold is a really kludged DIY thing - drilled/tapped for the fittings
    • it's not actually a manifold... each port is separate
  • I'm using NLGI #1, no moly.  Any thicker (or much longer hoses) and I'd run the risk of a hose popping out of a fitting.
Z-axis has a similar 'remote fill' system as the Y-axis.

Couple pumps 3-4 times a year (low use machine) and no issues since installed.

You do not need mesaflash unless you need to change the firmware.
Use MesaCT to create a config and test the machine.
-
From your posts it is unclear what you are trying to achieve, you mention Mach3 and 4 used for position control on stepper driven machines, but here you are using a Mesa 7i97T that is explicitly for analog servo drives, so what gives?
