Help Controller for a Lathe ?

There are many reasons why you should not use MPG for turning, but I will give you just one - you can turn the handle faster than the axis is moving, in other words, when you are done turning, the axis will continue to move until it reaches the commanded position.
 

Thats not correct. The user can choose how he wants his MPG to operate when he sets it up. Now I am the old crank!

Thanks for any replies. I managed to repair my machine for the time being, but I still want to upgrade the control system. I’m currently building a makeshift lathe so I can experiment and find the best control system. I’m planning to try LinuxCNC with the 7I96—since it’s constantly being developed—though I’m not sure if I’m capable of setting it up. Mach3 is no longer being developed, but it would be my second choice, paired with an Ethernet breakout board like the PoKeys57E.
Best regards,
Hans

LinuxCNC MPG inputs can be configured to stop moving as soon as the MPG stops. (Because this is such an obvious problem)

I use UHU DC servo controllers. They compare the actual position with the target position. If the deviation is too large—for example, if I crank faster than the axis moves—the controller goes into a fault state and stop the axismoving.

Use 'joint.N.jog-vel-mode' as advised by andypugh.

I have started to delete some of your pointless arguing.
Your behavior has become a nuisance and I'm not willing to put up with it any longer.
Either you find a constructive way to interact with people on this forum or I'm afraid you'll have to leave.
