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. 

I think now it's success compile.
 

then I cmd : sudo make setuid

I try open sim xyzbc-trt-kins
I'm open hallshow and click to check inside pin--> xyzbc-trt-kins   but not have show pin skew-y
have any step ?
 

Thank you,

Looking at your pictures again, and they don't make sense...

The time between index pulses is ~1.2 seconds in both pictures = ~50 RPM

100 RPM would be 0.6 seconds per index, 200 would be 0.3
 

Standard 7I96S firmware has 4 built in MPG quadrature counters
overlaid on the first 8 isolated inputs. This means you do not need
to decode individual inputs (which is important since they are typically
only read at the 1 KHz servo thread rate)

The MPG counters have names like:

hm2_7i96s.0.inm.00.enc0-count
hm2_7i96s.0.inm.00.enc1-count
hm2_7i96s.0.inm.00.enc2-count
hm2_7i96s.0.inm.00.enc3-count

Thanks, I don't know if I did it right but I got an error message.

Removed setp from HAL file and retested. No change in observed behavior.

Yes, multiple passes at same speed are perfectly aligned with previous passes. This is true even when machine is turned off overnight and turned on next day (and re-homed). I don't think I'm losing pulses in the stepper motor. You can usually hear the motor miss pulses, and the results are reproducible.

10 count per turn encoder results in delta Y per pulse of 0.0125" for 8 TPI. Seems like the error would be less that that, and I'm seeing 0.085" error at 200 RPM.

you need to install the build dependencies. See 4.2.2 in the linked documentation above.

Or you open "/usr/lib/python3/dist-packages/probe_basic/probe_basic.ui"
and change line 365:
<number>8</number> to <number>0</number>
Number "0" is first tab (main).

Hi Aciera

I use this 

$ git clone github.com/LinuxCNC/linuxcnc.git linuxcnc-source-dir
$ cd linuxcnc-source-dir/src

and I replace file trtfuncs.c  (inside skew func) on this step (correct right ?)
Then, cmd :

$ ./autogen.sh
$ ./configure --with-realtime=uspace

it's look good  and I use  cmd : $ make

it's loading and show in picture attach file  , this not complete compile right ?

Error :

/bin/bash: line 1: a2x: command not found
make: * [../docs/src/Submakefile:1001: ../docs/man/man1/5axisgui.1] Error 127

How to solve this problem ?
I think it's near succes with your help ^^"

Thank you,
Asis

 

Hello everyone.I am very interested in control via Ethernet, and I became familiar with this method some time ago. However, I am encountering a problem. I am currently testing everything on just one stepper motor. My system is LinuxCNC version 2.9.3, which I use to control the EC500 controller (running on the RT-1052) via Ethernet.The EC500 already has firmware installed:and a JSON file:. When I launch LinuxCNC, select the "remora-ec500" configuration, and then run the standard G-code file provided with LinuxCNC, the process starts, but the stepper motor does not turn.My EC500 controller is connected to the control output via an HBS86H driver, which controls the stepper motor. This setup is a closed-loop servo mechanism that operates autonomously (without the involvement of Remora or LinuxCNC). However, this configuration does not work when I load theJSON file onto the EC500 and run LinuxCNC with the corresponding HAL file for DMA-based control.Interestingly, after changing the JSON file toand launching LinuxCNC with the appropriate HAL file for the BASIC version, the G-code program starts working, and the motor begins to rotate using the same unchanged hardware setup.I used the HALSHOW environment to monitor and compare changing pins and signals for both the DMA and BASIC configurations, but I couldn't identify anything significant for myself. It’s possible that I am missing something, which is why I am getting these results.Scott (or anyone else on this forum), could you spare some time and provide me with any insights or information that might help me move forward? Perhaps it's some small detail, like an enable signal or something similar, that might be causing the issue (even though I did see in HALSHOW that this signal appears to be the same for both configurations).Thank you in advance!

Well not completely, I'm still just a baby on this stuff trying to get it functional. Will be on the learning curve for a long time I feel. I have not been able to get the Hole or Facing Conversationals going, which to me would be the next step. Once these are working I feel that it will be working well enough for me to understand some of the basics. I did complete some manual GCode instruction processing. So I know that aspect works. Just wanted to get the conversationals working as I can see these being invaluable when starting out.

On the ATC, I don't have one as yet, but am working towards creating one. The Mill being converted is a PM728VT. So Spindle control is available. I need to get to this once the machine is together. I am only bench testing atm. Still need to fit the ball screws etc.. yet.. The plan is to have the ATC will be managed via a pneumatic drawbar. Still trying to figure out best way on the tool change. Thought a set on the side of the table for pickup and drop off wud work best. A rotating one, although good is a little way off for me.
