OLD Lathe conversion to a CNC

Yes, you are right .  I saw your video on YouTube.  You made amazing parts with the lathe.  Well done! 
 I turned on the display today.  Now I will play with the configuration.

 

A little update, I made a telescopic way cover for protect linear guide .

 

 

 

 

 

 

 

 

I made a video compilation.  I had to make an additional metal construction to level the table.   In the video you can also see a test measurement with 0.002mm dial indicator .

Hello, I have a question. I want to emphasize that I am new to LinuxCNC! The spindle has separate oil lubrication. I want the pump to not run all the time. Only when the spindle is rotating. A pressure sensor is installed.
I want to do before the spindle turns to turn on the lubrication pump and wait for the enabling signal from the pressure sensor. When true to rotate the spindle. If during rotation the signal from the sensor changes its state, it is not true to trigger an alarm. What is the right way? Is there an example? I'm sorry, but I couldn't find a similar topic.

Probably by remaping M3 would be the best way, but no idea if M3 can be remaped.
I am sure it can be done in hal but that is quite a journey.
Using M6 or M7 is much easier, see mist/coolant use, requires adding an output for it in wizard, be it StepConf or PncConf.

I don't think it would be that hard in HAL.

This will also stop the spindle if the pressure falls, which probably isn't desirable, so you could add a latch:
linuxcnc.org/docs/stable/html/man/man9/flipflop.9.html

in addition to (most of) the above

This will turn the spindle motor on when there is pressure and the spindle is on, but will only turn the motor off when the spindle-off (inverted spindle on) goes true and resets the latch.

If you want an alarm too, then that would be based on the latched output being on, and the pressure being low.
Add another not, used to create an output that is high when the pressure is low, and another and2
linuxcnc.org/docs/stable/html/man/man9/message.9.html

Many thanks for the quick and detailed reply. I will try soon.

What's missing from my HAL file. I cannot do protection if the requested RPM of the spindle do not follow the current RPM from the encoder.

 

 

The problem is that the machine should automatically stop if the pump is not working.  The spindle is large and if left without lubrication the bearings will break.
 

Can anyone help. I can't find where the error is..
I am attaching the new files!

 

 

I start the spindle with Gmoccapy gui

What is the actual issue with the current hal/ini file set?

Hello, when I start the spindle with S1000 m3. The spindle rotates without the set acceleration and if I simulate a deceleration or stop of the spindle there is no following error. The machine/spindle works without errors!
