Upgrade? Chinese CNC Machine

[JAZZCNC]

I Was gunna go buy three new nema 23's but they have from memory bolt holes that are 41mm <--> the bolt holes on this machine are 50mm <--> so the only way to have spares is to get the nema 34's which in the ad says have the same 50mm bolt holes? but are more expensive!!

Back to confusion again

If they are 50mm centres then It's got Nema 24 motors on it which are 49.8mm bolt centres where has Nema 23 are 47.14. Nema 24 motors will measure roughly 60mm outer dimensions and Nema23 56.4mm.
Nema 34 are 70mm centre holes. They would also be a big mistake to use with M542 drives and give much lower speeds.

Hello,

I'm new on this forum.

I have the same CNC, 3020Z-D52.
I bought the Gecko G540 to replace the stepper controller because is losing steps and I would like to inform me if I could use the Spindle controller of the D52 to connect it via PWM in VFD output of the G540.

Thank you in advance
Nikos
