I'm sure one on my exes had a Common Vagina, everyone used it.

I had a look inside once and I'll swear I saw a Texan looking for his horse.


Serial Port looks a little weird as well.

Look for a touch screen that enumerates as HID (USB). Human Interface Device, these need no special drivers or such.

This setup is for sale.

Sadly i only can add 8 pics in one post.
So here is one of the spindleservo with fan, gearbox, brake, belt...

 

and the machine in the warm workshop 
 

Hello all,

I have taken on a 2.2-ton heavy problem and started a new project: a CNC lathe from WEMAS, or Kovosvit MAS, built in 2000. So, it’s a 25-year-old German-Czech machine.     History of the machine: This machine was purchased by a larger company in 2000 and was used in prototype production until around 2004. Then, it encountered an issue with the electronics. After an internal move—after which it was never repaired—it was slated for scrapping. But that was far too good of a machine to throw away! Luckily, a dear friend stepped in to prevent that and played a significant role in getting it to me (thanks again, you know who you are!). To summarize: 2.2 tons, incredibly top-heavy, difficult to move, barely liftable, and broken... why would anyone take this on? Fortunately, I had professional help from my family for the (not-so-simple) transport, and it was soon safely at home. We disassembled it while it was still on the trailer to make it more manageable. It’s a massive cabinet made of robust 3mm steel sheet—very sturdy and maintenance-friendly, but it takes up a lot of space and isn’t exactly hobbyist-friendly. Plus, the weather wasn’t on my side, so I had to make it smaller quickly despite various challenges.   
 Here’s a first look at its inner beauty. It stands there nearly smallish without the cabinet (I’d compare it roughly to a Weiler B Condor). To move it without hydraulics or a crane, I built a chassis from scrap parts (a broken flange and the lower part of a vice plate) using some hardware and heavy-duty wheels.With this setup, it can be maneuvered easily and very precisely with one person. it’s now flexible enough for the casing modifications. I’ve also given it a bit of a clean.

      Next step is planning and buying hardware for the conversion to LinuxCNC. I’d like to continue using the servo motors, as I believe they are definitely worth preserving. In particular, the spindle drive is fantastic. It’s a SIEMENS asynchronous servo motor with an external fan, brake, and a two-speed planetary gearbox. The motor can reach up to about 9000 RPM. Through the belt drive, I have spindle speeds of 0 to 1000 and 0 to 4000 RPM. Given the well-designed bearings and the belt in between, I’m hoping for excellent Surface-results.

Unfortunately, the large motor is both a blessing and a curse. The Heidenhain compact inverter is actually brilliantly small designed and should still work fine. However, it seems that the folks in Traunreut have turned it into a complex project, and it looks like you can only connect this thing to HH controllers. Documentation on this is almost non-existent, which is frustrating. So, finding a suitable (small) inverter for the spindle servo is not easy, and it’s not cheap either. The best option might be to go with a SIEMENS S120. However, the software, namely TIA Portal, is a significant hurdle for me.

I’ve been mulling over this for a few weeks now; if it weren’t for these issues, the machine would probably already be moving. I might even take the plunge into EtherCAT. That way, it could be easier to buy new motors and drivers for the X and Z axes directly (with absolute encoders and position feedback).

Finding a suitable driver for the large SIEMENS 1PH7105 servo is quite challenging. Perhaps something from Beckhoff, like an AX51? Or again a SIEMENS S120, which can sometimes be found very cheaply on eBay, although it’s primarily designed for ProfiBUS. There is an EtherCAT adapter available, but I fear that no one has tried it with LinuxCNC yet, and I don’t have the skills to tackle that.

Unfortunately, LinuxCNC and EtherCAT are still a bit of a mystery to me. I’m looking forward to hearing your thoughts and tips!

Best regards,
Tom

 

Hello Everyone,

I am planning to convert a BF20 Optimum Mill to CNC and want use rigid tapping.
I am currently redesigning the spindle. For rigid tapping, a encoder with A, B and Z pulse is needed, atleast that is what my reserch got me.
I would like to have the encoder directly on the spindleshaft, so no beld needs to be used.

So my question is, how many slots does this "encoder disc" need to have?
(1 slot would equal 2 pulses right? Rising edge and falling edge?)

And would it be possible and practical to use a ac motor with a vfd to do rigid tapping?

Any input is highly appreciated.

Thanks in advance!

"Python can find the path to the running code with the __file__ system variable."

I know it now.
It's even used right here:
github.com/LinuxCNC/linuxcnc/blob/1c72d4...cconf/pncconf.py#L33

"In both cases you probably need to use the Python path manipulation functions to assemble the required path."

stackoverflow.com help me with it. It is not problem for me.

Now I have enough information to implement my original plan.
Create new files in the linuxcnc/src/emc/usr_intf/pncconf folder and then copy them to the new LCNC configuration using pncconf.

However, @Aciera came up with a better idea.
He doesn't want to create new files in the linuxcnc/src/emc/usr_intf/pncconf folder.
He wants to use the original data from the configs/sim/gmoccapy folder.
The advantage is that there will be no unnecessary duplicate data in the source files.

The problem is that I don't know how to define this path cleanly: configs/sim/gmoccapy
This path is different for RIP installation and different for package installation.
github.com/LinuxCNC/linuxcnc/blob/40fe3e...rc/configure.ac#L702
github.com/LinuxCNC/linuxcnc/blob/40fe3e...rc/configure.ac#L724
I think this might solve my problem, but I don't know how.

Hello all, i tryed to start a new topic in "CNC Machines Lathes"

Sadly it dosent let me post :/

Is there a problem or is the problem in front of my pc?

 

I Found a problem
If use FACE process
next step after FACE , not include G64 P Q Line
maybe problem from Post Processor of fusion360 

now my post $Revision: 44166 e813d608ccd22fb0949f73fcdb773b434407b131 $

I put G64 with PQ in  adaptive clearing step3 now can solved no machine jerky
Problem not from linuxcnc , problem from Post .

Thank you

Hello, I have gotten Linuxcnc running in my RPi 5 with MESA and am now moving on to cutting chips the original build uses a 10" Raspberry pi touchscreen (this: Cool hood 10.1 RPi screen), but I can't get the touchscreen part working. In the meantime I realize that 10" is small and I'd love to use the Probe Basic interface which required Full HD (1920*1080).

​​​​QUestion is: what touchscreen in 12-15" size have been proven working with a RPi 5? 

I am interested in the Waveshare 13.3inch DSI LCD ( Waveshare ) as it seems to fit from compact dimensions and have drivers for bookworm. I see these are dependent on kernel though so I am now fearful it may not work with our RT kernels? 

Any experience or other recommendation? 

​​​​​​Thanks!

I think at the end making your own encoder is similar effort like mounting a small timing belt.
Unfortunately hollow shaft encoders are much more expensive than the required parts. (timing pulleys, small timing belt and cheap encoder)

Maybe I should try ordering a slotted disc from a PCB maker for 2USD? They do drilling and milling and it is a matter of sending them the correct pcb file.
 

Hi
Now I use Linuxcnc V.2.9.4

I have a problem when Post G-code from Fusion360
If I post 1 post 1 command (Adaptive clearing) it's No jerk
but When I post  3 command in Gcode  
1. Adaptive clearing (tool 16)  Not jerk
2. Face  (tool 15)  Not jerk
3. Adaptive clearing (tool 16) Jerking

Step 3 my machine will jerk  when entering a curve and Velocity move slow down to 10-30 % feed , And will back to 100% speed when back to linear move .

My post I use
G64
G64 with P
G64 with PQ
Same problem can't solved .


 


I try
Post Gcode only Step 3. Adaptive clearing  it's not have a problem can run full speed and machine not jerk 

How I can fix this problem ?

Thank you
Asis

never trired OpenOCD, but you can send me the error mesage of the openfpgaloader.

with openocd you should make sure that it is written to the flash and not just to the ram, otherwise everything will be gone again after a restart

You can see whether it has worked by the flashing LED

btw, the default ip is '192.168.10.194'

the w5500 module has a little power led on the bottom, there is no jumper to power on/off this module.


not realy shure what you mean with the mapping,

the bob pins are mapped 1:1, if you need P17 (relais) on the BOB, you can use 'LEFT:P17' in your config.

 

if your BOB is connected to the other connector on the right, then you need to use 'RIGHT:P17'

 
So for a standard 3 axis mill, is the below scheme for wiring somewhat right.  I have no idea how to make a config for a lathe Though!  The second image has a funny output as marked
