That's a warning, not an error. You can usually fix it by copying the libusb.dll (libusb dynamic link library) to the path of your Python installation.

Note: If you downloaded Python from the Windows Store, you should copy libusb.dll to the C:/windows/system32 directory.

I spent 20 minutes trying to sketch a simple part to revolve and gave up after the autoconstraint engine completely hosed up the sketch. They really really need to put work into the sketcher and the UIX , it is still god awful to use. Hell I am willing to donated money on a monthly basis to get out of using fusion360 at this point, but there doesn't seem to be any seriousness from freecad developers about working on it fulltime.

comp file is a list of nominal (normal) position and compensated numbers in each direction.

ie (type 0 compensation)

10, 10.1, 10.08

Meaning when you move to position 10 in forward direction, the machine will move to 10.1.
In the reverse direction moving to 10 will actually move to 10.08

You need to leave a little bit of max acceleration head room for the machine to apply compensation.

I've never used it, just interpreting info I have found.

please let me know how it goes

The default timeout for wait_complete() is 5 seconds.
Do you need wait_complete?

I have a machine coming that uses a motherboard with a pcie card. I don’t know the model of the card yet.

Should I try and use this or just switch the more modern Ethernet card?
 
Im assuming the original HD is bad.  That’s why they sold the machine.

 

Well I looked in every single box.. nothing. bah!

Good catch. I ran the test again, and noticed that HalScope does not update the picture except after every scan - that was probably the problem. I also made all the pictures at 100 ms per division. Here are the revised photos. I also made a zoomed in photo of when the movement starts, so I could read off the delay.I'm not sure if that has any significance.

100 RPM - 30ms from falling index to start of Z movement
 

200 RPM - 17ms from falling index to start of Z movement

thx i will try it

This is an open source project "electronic gears". Very popular among home craftsmen in the territory of the former USSR. The main functionality is to replace the mechanical gears of the guitar machine with an electronic drive. The first versions automated the operation of only the longitudinal feed. The current version 7.2 allows you to automate the operation of the transverse feed. Such operations as thread cutting, cone, sphere - do not require manual dexterity.
Naturally, the Chinese brazenly put it on the WEISS EL250 machine, passing it off as their own development. All comments on YouTube are banned )
The project address is www.chipmaker.ru/topic/118083/ Author - Oleg from Riga.
Initially, I used LPT control based on 2.7 for CNC and ELS for manual work. The BOB25 board is perfect for this. It is enough to pull out one cable and put another.
Using NativeCAM allows you to no longer switch cables. And use one system for convenient control of the machine. Here is an example (video is not mine)

1. Note that the compiled installation is separate from the package installation you worked with before so you need to modify '~/linuxcnc-source-dir/src/emc/kinematics/trtfuncs.c'

2. then cd to ~/linuxcnc-source-dir/src and run
3. if that was successful you can start the compiled installation:

conversational is useful for small quick jobs, but most parts will use cad/cam software to develop tool paths and part programs to be loaded in the PB control to be run.

conversational requires you to setup the tools to be used in the tool table and save and reload the table. then in the conversational, determine which parameters to enter in the required fields to accomplish your desired motion and enter them in the appropriate boxes. then set the work coordinate offset so that the motion is adequately inside the cmachines configured work envelope. it seems you have a long road ahead of you, but your install is now functioning correctly, so once you develop the correct cnc machine knowledge you should be able to accomplish your goals!

Good luck with your Journey!

I've had good luck getting everything to run well enough to get deep into learning and configuring LinuxCNC, Mesa 7i95T and the needed .ini and HAL files.  However, I just ran into my first problem when LinuxCNC errors on start when I configure QtDragon as the interfaces. 

I've already worked my way through several prior fail-on-start situations chasing down reported errors from the usual sources but this one is stumping me because I can't seem to find the actual error in the outputs I'm aware of.I will attach everything I can think of if someone could take a peak and spot what I'm missing.

Thanks

Due to job change, I have to sell my almost new LinuxCNC:

Precision Matthew PM-25
Mesa 7i96
DM856 and 2x DM860 drivers
KH34 and 2x KH23 step motors 

the machine is located in Providence, RI which is about one hour driving distance from Boston.

Please private message me for the price.
