Fehlmann Picomax 50 CNC conversion/refurb

[Agathon]

Using a motion controller is night and day difference. I don't want to get into the Mach3 V Lcnc I use both. But If you say do a feed hold in Mach3 and it is in a cycle it won't stop until the cycle is finished with Lcnc it will stop immediately.

I you decide on the Lcnc route with steppers you would need a Mesa 5i25 or 6i25 (pci or picx) and a 7i76 bob that would give you at least 34 input and output, 5 axis 2 encoders. spindle control, 24V inputs differential signaling etc.

Lcnc is a steep learning curve but it is a rock solid system. It will do what ever you want.

I think you said you had 4mm screw if so I don't think you can go much faster rapids with a nema34 I think the max motor speed would be 500-800 rpm.

Thanks once more Clive. Many things to look into and think about. I'm happy with the 2000mm/min rapids, I'm still somewhat incredulous that those old Superior steppers could run any faster.

Sorry about the cock-up with the video editing btw. Don't know how I managed to get two copies in one video.
