No, I accidentally deleted all of the posts one category except 1. Instead of the desired trim of 5 years I trimmed to 30 days which is the default span so only one post was left and most of the posts described machine builds.

Hello Andre, Would you be willing to share your schematics, or tell me which machine and revision they cover? Even photos or scans of the pages would be a big help. I'm also happy to pay for your time or share what I document on my side.
Thank you very much!

I have a LOT of old machines that were upgraded and work much better.
I am old and i do much better work now than when i was young, no idea when the upgrade happened!

The Fund Rave is live again!
Show us your love - we're already at 30% of our goal!
Cheers!

I have nothing against an upgrade.

Isn't that exactly what we just dealt with?

Hi PCW,

I'm retrofitting an SWI Sport B3 bed mill (ProtoTRAK M3 control) with a 7I92M (Spartan-6 LX9, `6slx9tqg144`) and the original ProtoTRAK servo drives (locked-antiphase PWM, ~15.5 kHz, 50% = stop).

Right now it runs on the `7I92_7I85SPX2` bitfile from the "Where to start with Mesa 7i92 + 7i85S" thread, with a 7I85S on P2: PWMGen 0-2 drive X/Y/Z (output-type 1, 50% offset done in HAL as you described), muxed encoders 0-2 read the motor encoders. The X axis is up and tuned.

I've now added a **7I77 on P1** for the MPG, a quill encoder and a spindle encoder, plus field I/O (E-stop, limits, home switches) and possibly the spindle analog output. Later I'll add a rotary table with a step/dir drive.

Could you build a bitfile with:

**P2 (7I85S), same pin positions as 7I85SPX2 so my wiring doesn't change:**
- PWMGen 0, 1, 2 on P2-5/6, P2-4/17, P2-3/16 (as now)
- **StepGen** in place of PWMGen 3: step on P2-2, dir on P2-15 (for the rotary table)
- MuxedQCount 0-3 with MuxSel on P2-7, inputs on P2-8..13 (as now; 4 encoders with index)
- SSerial pair on P2-1/14 (as now) if there's room; not needed otherwise

**P1 (7I77), standard 7I77 layout** (as P2 in `7i92_7i77_7i85sd`):
- SSerial channels 0-2 (TXEn2, TX/RX 0-2) on P1-1/14/2/15/3/16/4
- MuxSel on P1-17, 3 muxed encoder inputs (6 encoder channels) on P1-5..13

So in total: 3 PWMGens, 1 StepGen, 10 muxed encoders (4 on the 7I85S, 6 on the 7I77), SSerial for the 7I77 (and the 7I85S's if possible).

Thanks very much! 

 

I got a reply from a human very quickly, and made the edit they requested. Once they review the edit it should be live again.
Cheers!

I got an email from GoFundMe saying they don't like something about our campaign, and have suspended it. I'm working to clarify things with them.
I also change the link to the full URL, and that was working until the suspension.
Their initial reviews are done by an LLM, which errs on the side of caution, so I'm not too concerned at this point. Once a human reviews things I'm confident we can move forward. I'll post again when have more information.
We've already reached more than 25% of our goal!

The link is not working for me, it just shows me their main page.
Searching for LinuxCNC also does return nothing, and so does searching for the code ID.

Hi, folks.
As I'm sure you all know, the forum has been suffering growing pains for quite some time now. The operating system and forum software have not been upgraded in a decade, and are well beyond end of support. The hosting platform has been paid for by one developer out of pocket for the past 20 years. We need to upgrade the hosting service and upgrade the software. JT has already shown that we can upgrade the current system, but due to lack of resources the upgrade had to be reverted. We're looking for donations to fund the new platform, and plan on upgrading to a more modern OS and forum, retaining all data from the old forum. We are not considering changing to a different forum platform at this point. The immediate goal is to upgrade the software and move to a more capable hosting system.
To that end, we've started a GoFundMe to solicit donations to host the forum. We're looking for $2000 in donations, which will cover hosting for the next five years. We need a long-term solution so that we're not scrambling to keep it going in the future. We are hoping to reach that goal by the end of this month. If we do not reach our goal we'll refund everyone's money and look at other options.
If you find this forum a valuable resource, please consider donating. We're suggesting $20, which amounts to $4/year, but if you can give more, that would be great. If you can give $5, we would be grateful for that.
To donate, please go to www.gofundme.com/manage/donate-to-upgrade-the-linuxcnc-forum .Our sincere thanks to all who can help. Cheers!

I can hardly imagine the storage required for the many years that the forum has been collecting data. What is it, about 17-18yrs? Hosting it can't be particularly cheap or easy.
 
That is why I suggested closing the old forum and leaving it exactly as it is.
For standard, day-to-day use, it is unacceptable to have to wait several minutes for a page to refresh, or to constantly battle bot attacks—something the old software is no longer capable of handling. However, for someone only seeking information that cannot be found anywhere else, this state would be acceptable.
We could set up a new forum—for instance, newforum.linuxcnc.org—migrate only the user accounts, and stop tilting at windmills.
 

Once the forum is upgraded and we have more memory and better cpu the forum will be much faster.

LinuxCNC on KMotion from a USB stick

A ready-made Debian 13 system with LinuxCNC, the KMotion motion module, the KMotion tool and KMotionXCNC already installed. Start a PC from the stick and it runs: nothing is installed on the PC and its disk is not touched. The stick can keep your settings and machine configuration from one start to the next, and the same stick can install the system onto the PC's disk if you decide to.

For a KFLOP (USB) or a Kogna (Ethernet). No real-time kernel is needed: the board does the real time.

What you need

• A 64-bit PC (Intel or AMD) with 4 GB of memory or more; 8 GB is comfortable.

• USB stick: 8 GB runs it; 16 GB or more to keep changes (32 GB if you will also update the software on it). A USB 3 stick in a USB 3 port makes a large difference in speed.

• The image, about 4.5 GB: dynomotion.com/Software/LinuxCNC/
  (kmotion-linuxcnc-<date>.iso and kmotion-linuxcnc-<date>.iso.sha256 beside it).
  
  Full Instructions here

For existing Dynomotion KMotionCNC Users there is now a migration tool that can mostly convert a KMotionCNC configuration into a LinuxCNC configuration.

The Debian VB has a shared folder with Windows. Copy your KMotion installation to that folder. If your configuration references files outside of the installation folder copy those folders also. It is normally C:\ShareVM\kmotion

 

In Linux it is normally /mnt/kmotion

 

There is a desktop icon in Linux for the migration tool

 


Run the migration tool and it should find the configuration to convert. If there is more than one found it will ask you to choose. It wlll also ask for a name for the configuration. Here we entered TK

 

In this case the LinuxCNC Configuration is placed at /home/tk/KMotionX/KMotionX/linuxcnc/configs/TK/

 

Note that the KMotionCNC settings such as X Acceleration has been migrated into the ini file

 

A Desktop Icon will be created to run LinuxCNC with the new Configuration
