Centroid Community CNC Support Forum

Does anyone know the pitch of the leadscrew and the pulley in the stock 1210hs ? I bench tested my Acorn and G203V drivers and am ready to connect up to the machine.

Yes, the link posted by Nigelo showing how a F1210 hs was converted really helped.

I ordered an Acorn controller and 3 Gecko G203V. I am deciding between 3x 36V 200W switching supplies vs 1x 36V 600W switching supply. I would like to reuse the existing cabinet and switches so whichever option fits ...

Thanks Nigelo ! Off to digest the tips you provided.

Photos and info on the mill:

The mill was fitted with a CNC controller and stepper drives from the factory. The stepper motors are SanMotion 103H8221-6241 (2 phase bipolar, 388 oz-in holding torque, 6A rating, 0.3 ohm/1.65 mH windings) on X, Y and X axis ...

For axis I used Clearpath motors SD but presently I think that servo motor like delta Asd- a2 or Estun (with output signal) is much better choice due to avoid home switches for homing (more precise homing process)


Thanks ! I'll try to get his machine working with the stock steppers and let him ...

It looks like there is no VFD to process the spindle speed signal.

I like the wabeco milling machines, if you manage to migrate from that weird CNC software it came with, and install Acorn on it, it will run great.


The machine seems to have a VFD (M1 in the schematic below) that supports 10V ...

We'll post photos soon. Thanks !

Thanks Uwe. I'll make a wiring map to use an Acorn controller and Gecko stepper drivers as a first step.

I am helping a friend with his 1200HS mill. It came with nccad7.5 software and CNC controller that seems to be proprietary and never worked.

We are thinking of replacing the controller hardware with Centroid while keeping the stock stepper motors, limit switches and spindle.

Has anyone done ...
