Centroid Community CNC Support Forum

hello again things are coming along with my cnc conversion and i have decided id like to get spindle control thru the cnc12. i know this isnt a very popular machine but i have seen at least two others on this forum who have this machine running with the acorn. I saw a video franco put out about spin...

The jack screws in the ACORN should unscrew easily. The shielding will be less than ideal when using a breakout board anyway. Just run the drain wire to H9 EGND or an ACORN mounting hole. yes they unscrew easily but now both sides (the acorn board and the db25 male b.o.b) have the threaded tab sold...

so this may be a stupid question but i have the acorn board and im using a db25 bob but the board and the bob both have the threaded stud with female nut i figured i could just take one off and put a screw but the threads are soldered to the board im assuming for sheild termination so whats the best...

If the device does not have a ground wire, it probably has a ground screw. You connect the two hot wires to the fan leads and ground to the screw. Exactly as Tom stated. The ebmpapst German, 220v fans I use are METAL, not plastic, and they have both a 8-32 and a M4 threaded hole next to each other ...

I agree, a 220v fan would be ideal. I use them all the time in my cabinets for customers and it'll last longer than those cheap, plastic 12 and 24 volt fans. Make sure to have the fan blow/suck cool air IN to the cabinet and put a grill near the top of the cabinets for the hot air to be pushed OUT....

im in my final stages of getting everything together for my controls enclosure and would like to add a fan to keep drivers cool etc. my mains input is 220vac 3 wire no neutral so a 110volt fan is out of the picture. would it be a wise idea to get a 24v dc fan and run it off the centroid psu or will ...

on the wiring diagram for my driver it shows home all/limit switches into input one ran in series. with this wiring will the switches work as limit stops or just for homing

The correct voltage for stepper motors is based on their inductance. See this thread for information: https://centroidcncforum.com/viewtopic.php?f=60&t=6511&p=56629&hilit=Inductance+voltage+equation#p56629 so with this formula i can get the max voltage? but im not sure what voltage to u...

also does anyone know what wiring schematic i should be using for these drivers i saw the leadshine dm series wiring diagram but it does not mention the 860 thanks again

i bought a ebay special stepper motor, driver and psu bundle for a 3 axis manual mill i am converting, nema 34 stepper motors 6amp 12nm dm 860a drivers and a power supply for each driver. PSU is a longs S-350-60, 24-60v output so two main questions for now at least. they dont really specify what i s...
