So, I decided to upgrade my Sahpeoko 2 quiet spindle from 300W to a 600W, i plugged it in and turn my Power Supply on, I started by increasing the speed from the Speed Controller nob, and it started spinning Ok… but at a quarter of a way the spindle locked slid, and the red light on my Speed Controller went off… now it wont light up and it wont work even when I switch to the original 300W Spindle…

Is there a reset button on the Speed Controller? or did I fried it?? :frowning:

Any help please?

Thanks!

Do you have a multimeter available to test the DC voltage from the power supply? Also, have you bypassed the speed controller and connected the spindle(s) directly to the power supply?

Here is the “Note:” from Inventables site;

“Note: This speed controller will only work with our 300W spindles. We are testing controllers for the higher power spindles, but don’t have a firm date yet for when they will be available.”

Hi Neal! Thanks for the help! That would be my next step I guess… I’m just worried that now my speed controller wont work, and wont be able to cut… but like u said, I can go straight to the power source and by-pass the speed controller… right?

Yo Marcky! :slight_smile: I did it again… :’(
So this means I burned my speed controller???

Ok, checked with my multimeter and I get 48V coming into the speed controller but “0” coming out of it… Is there a chance that the speed controller could be reset?

Unless your power supply is only a 400 watt power supply

@Marc_Schaefermeyer
mmmm… u think that running the larger spindle on the small speed controller might of cause the spindle to lock solid? I can only make it spin with a wrench…

The spindle locking is very odd. There are two things I know that would make that happen: A physical obstruction or an electrical short. Completely disconnect the spindle power wires and then try to rotate it. (If the leads of a DC motor are shorted it effectively “brakes” the motor and makes it really hard to turn). If the motor doesn’t spin freely when it is disconnected then you may have shorted the windings somehow.

BTW, if you have 0v coming out of the controller then it is shot. Probably burned up a MOSFET when the spindle tried to pull too much current. The power supply has over-current protection but these cheap controllers most likely do not.

Hi Neal… I wired the original quiet spindle that came with my shapeoko and it works when by-passing the speed controller… however the new speed controller is locked solid (I thought I was making it spin with a wrench, but it was only the fan housing).

When I connected the spindle the first time, I notice the fan housing wobbling like the shaft was crooked, after a few seconds it came to a stop… I didn’t even thought about spining the spindle by hand when taking it out of the box… :frowning:

@Neal_Wallace
… yeap! speed controller fried… :frowning:

Sorry to hear that dude. You have the inventables speed controller, right?

If so, I see in the pic there is a fuse under a blue translucent cover. Pop that bad boy out and see if it’s blown.

@Neal_Wallace
Kool! Let me check and see :slight_smile:
Thanks my good man!

@Neal_Wallace
AAHHHhhh! ur the man! Bad fuse!! :smiley: I’ll take a trip to Radio Shak and see if they have it in stock… how do I know what kind it is?? there’s no writing on it…

If you don’t see any text stamped on the metal caps, then see if you can roughly match the thickness of the filament inside (it’s probably hard to see). So, just guessing using Ohm’s Law, 48V and 300W would probably output 6amps. I would get a pack of fuses but don’t put one in larger than 6A.

@Neal_Wallace
Thanks Neal! I appreciate ur help! I’ll let u know what happens… :slight_smile:

I would get a slow blow fuse to help with current spikes.

@Neal_Wallace
that looks the same… even the little wire in the inside, i hope my local radio shack has them… :slight_smile:

Nice call @Neal_Wallace ​ on the fuse. I have the same speed controller but don’t have it in front of me.
