New Centroid Teknic Clearpath officially supported configurations. Updated 5-10-23
Two connections choices.
1.) Direct Wire to Acorn screw terminals. For those that don't mind cutting cable ends and wiring up relays for the Clearpath drive fault signal. Change here from previous is to use 5 VDC supply voltage to the open collector screw terminals on the Acorn and therefore a resistor value change. Our testing shows 5 VDC works best with the Clearpath drive. Note the addition of a 100 OHM, 1/2 watt resistor. This resistor is recommended in all applications. Use 1/2 watt or Larger. (a higher wattage resistor runs cooler)

Wizard Step frequency = 200,000.
Note on Step frequency: Testing reveals good results up to around 300,000 steps per second. 200,000 step per second is more than good for most applications (mills, lathes, most routers) on routers when very high rapid rates are required the step rate can be increased using the CNC12 parameter #968
Steps per rev:
Clearpath SDSK currently are available in two flavors a 800 step per rev unit (RLN) and a 6400 step per rev unit (ELN). We recommend purchasing the 6400 step per rev unit. While it might seem common sense to set the step per rev in the Wizard to 800 when using the 800 step per rev Clearpath motor we do not recommend this. Centroid software was never designed to run a a step rate lower than 1600. So when using the 800 RLN unit use 1600 steps per rev in the Wizard. (you can use a higher number the only effect is the top speed will be reduced the higher the step per rev is used) and set the Clearpath Software so it knows that 1600 = 1 turn of the motor.
Steps per rev for the 6400 step per rev unit (ELN) for Milling machines and Lathes and some Routers 6400 steps per rev
For Routers that need more rapid rate speed use 1600 to 3200 (use 1600 if you want speed, use 3200 if you want good 3D performance)
If you need more top speed (Max rate = Rapid rates= G0 moves) than 1600 step per rev yields then adjust the step frequency manually to 300,000 with parameter 968.
Otherwise use the highest step per rev that will achieve the Max rate that you want so you have good resolution along with really good max rates.

2.) Plug and Play C86ACCP board from cnc4pc.com

Notes on C86 board. Unit works well. Simplifies the CNC control build to a plug and play kit.
1.) Both the Motor cables and the C86 board itself should be strain relieved properly during installation.
2.) Make sure Acorn screw terminals are very tight.

He says,
OK...Here is the scoop:
1 Ignore the schematics DO NOT SET ANY INPUT TO DriveOk at this time DO THIS LAST!!!
2 Put a wire jumper across the 2 terminals next to the power input terminals (new ones come this way)
3 Power the 86accp from the Acorn4 +24VDC& COM terminals, so it is on when the acorn is on
4 Set the Acorn Enable Jumper (next to the red power LED) to OFF
5 Make sure the Hard/Soft jumpers are all set to HARD
6 Set the ACTIVE AXIS jumpers for the X, Y and Z to ON (terms 2 & 3)
Are you using Independent auto square? Are you sure that you need it? If so GOTO #8
7 If you are pairing an axis (no autoquare) set all 4 of the SLAVE jumpers to 1-2 for X and 2-3 for Y. ALL 4!!!
If not using autosquare, install the C86 board into the terminals making sure that you are in all 16 terminals securely
GOTO #10
8 Set the ACTIVE AXIS (4th) mislabeled as "A" to on
9 Remove the 4 slave jumpers and set aside
Install the C86 board into the terminals making sure that you are in all 16 terminals securely
10 Place short wire jumpers connecting the 2 position terminals marked ALAR & GND together for each axis you will be connecting to
11 Connect 24vCOM to relay terminal V IN and Connect a wire from the NC terminal to the input you will use for DriveOk NC
Connect any ONE axis you wish to test or tune to its terminals or plug. If using terminals, Ignore the RED/GRN HLFB wires for now.
move and autotune that axis. Repeat, one at a time for the rest of the motors.
All done? All axes moving? Remove the short jumpers, install the red/grn wires and set the input connected to in step #11 to Drive OK
