The F1200 HS is very similar to my F1210 HS which has an extended table on X axis. My model was sold as "CNC ready" which in reality included stepper Motors ready mounted with timing belt gearing and kinetic limit switches all pre-wired with shielded CY 7 core cable for each motor / limit pair. Each cable terminates in a DB9 connector.

Limit Switches EUCHNER N01K550-M (Ball type) accuracy 0.030 mm (approx 0.0007") with excellent repeatability
Stepper Motors SANYO DENKI 103H8221-6241
Spindle is likely the same HS (max 7,500rpm) as yours with integrated VFD and manual FWD, REV and 0-100% speed control.
I converted this to run on Acorn using Gecko G203v drives and a 36v power supply.

Happy to assist with any info you might need - Just shout

If you want to control spindle speed and direction though Acorn rather than manually, its worth reading Lorenzo's thread who succeeded here https://centroidcncforum.com/viewtopic. ... 305#p35305
Ignore the topic reference F1410HS as he actually has the F1210HS

Hope this helps

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.

The controller and stepper drivers looks like the MCS100 from MAX Computer. The controller has a 32 bit MCU. The 3 stepper driver boards have a 8 bit MCU and 2.5A output drivers. The stepper motors are connected via a DB9 plug to the back panel.

The spindle motor seems to have a VFD that accepts 10V input based on the wiring and manual.

From this, I am thinking of replacing the controller and stepper drivers with an Acorn and a Gecko G540. Any inputs appreciated.

The link I posted above to Lorenzo's thread will assist with your spindle as he is successfully running the HS spindle from Acorn - Long thread but well worth the read

The Gecko 504 is not a good choice as current is limited to 3.5amp and will seriously limit your performance. As your Sanyo Denki motors are identical to mine they accept up to 6 amp. That is why I used Gecko's G203v with 240 Kohm 1/4w 5% current limiting resistors providing a safe limit of just under 6amps using a 36vdc Power supply. I arrived at 36vdc using Gecko's own formula (32 * √inductance = VMAX) = 41vdc but limiting voltage to 20 x motor's nominal 1.8vdc, the latter derived from 6amps x 0.3 ohms.

For 36vdc motor power I used Meanwell's MSP-600-36 power supply capable of 0-17.5 amps, enough for all 4 axes.
