OLD Lathe conversion to a CNC

Hello again, it's been a while. I'm now back working on the lathe machine. I connected the Modbus to the X and Y axis servo motors and also to the spindle – all working fine. I can read the load values from the servo motors without problems. But there is an issue with the spindle load display. Sometimes it shows too many zeros after the decimal point. I tried to fix this with Python code to cut the extra zeros, but I couldn't make it work. Has anyone had this problem before?
What is the easiest way to fix it?

 



 

New video

I had forgotten that the spindle  ratio setting was not set correctly. I had 8192 in the ini file, the new value is 14700. 

After replacing the processor there are no warning messages or the machine stops.

I made a new video a little long but it is a compilation of all the operations. The hydraulic chuck are missing :side:



PS:


Hello,
I had a rough week with my small lathe. After the workpiece slipped out of the jaws, the X-axis went out of alignment and had to be realigned. Luckily, that was the only damage. ?

 
 
 
 
 

After sudo apt update I started getting errors in real time (the old song in a new voice ) I tried many things and finally this helped: sudo apt install iproute2   
sudo tc qdisc replace dev enol root pfifo_fast

I made a new PWM board to +/-10V.
Now with isolated power supply and the possibility of differential analog output. Now the groundings don't mix
 





ps:I saw one mistake, I forgot to bring out the ground for +-10v
