Hello everyone, i just picked up one of my projects that has been standing still for a few years, a cnc router with 800x1000mm work area, it is a quite well dimensioned machine with double 25mm ballscrews and THK 30mm linear guides on the X axis, single 25mm ballscrew and 25mm HIWIN linear guides on the Y axis and a 2,2kW water cooled chinese spindle,

The thing is that i was originally building the control electronics for a parallell port driven 3-axis setup with a single ballscrew on X, but i moved on from that to double screws because of the drawer slide effect, so now i have a complete control setup with 3 Geckodrive G201’s that i need to rebuild to support at least 4 motors, i also need to get one more motor.

But when looking around the diy cnc world got so many more options nowadays… @Machinekit_io looks very intresting and the new closed-loop stepper servo systems seems awesome.

So, has anyone tried the “budget” closed loop cnc systems and have something to reccomend, i am thinking about changing out the X and maybe Y axis to run with that and keeping Z and optional 4th axis on the Geckodrives…?

Any reccomendations?

Very nice machine design.

@Arthur_Wolf : It is mostly built and looks quite nice IRL also (altough with a different simpler Z axis right now), just did not have any good pictures of it on this computer :slight_smile:

Anyone tried the Leadshine Stepper Servo drives and motors?

I’ve never used their servo drives, but Leadshines have a good reputation in the community.
There are more expensive but are also known to work well : https://www.youtube.com/watch?v=zM838mYFjcA

That video of the Omron drive is with a real AC servo, right? Those are usually quite costly… i actually have two Yaskawa 500W 200VAC servo motors lying around, but getting drives for them seems to be prohibitively expensive…

I am running steppers with Leadshine drivers in my
other CNC machine ( http://i.imgur.com/Egy1qb4.jpg ), so i know that they make decent drivers, i’ll just havnt tried any of the hybrid stepper/servo solutions, so i am looking for someone that has experience with those :slight_smile:
