I’m headed to gym right now to blow off some steam because I just spent 2.5-3 hours roughly trying to get a dado brake to work with no luck.

Only reason I need the dado brake right now is so I can cut a slot in one of the removable inserts in the Infinity zero clearance insert. I need to make a 45 cut in one of the blanks.

So I slapped on the dado brake and a dewalt 8” dado single blade and adjusted the brake so it scraped a nickel on the top of the brake where it’s closer. I got it adjusted, flipped the switch and got the error code. I kept adjusting in and out with no luck. I then read that for some reason it might be the riving knife housing, that it might be too low. I loosened the riving knife housing, flipped the switch and got the green light. Cool! I then cranked it to 45 degrees to make my cut and error code came back on

I then spent probably 45min-hour moving the brake in and out and moving the riving knife housing up and down without any luck at all. I unplugged the saw. Plugged it back in. Nothing.

I don’t know what to do. I’d like to be able to use a dado stack.

5hp CB 52” single phase by the way. Not sure what brake model it is but the old 9 pin I think, certainly not the new one .

Any tips?

I’m not sure if I turn the saw on, get the error code if it will go away if I move the brake in and out AND the riving knife housing up and down. Kind of at a loss.

Tomorrow I’m going to throughly blow out the area of sawdust and see if I can mess around with it. I’m also going to give sawstop a call and see what they say.

It’s also frustrating that Infinity tools and the guy that created the zero clearance insert, they made it hard to do the initial cut for a 45 degree insert. A 10” blade doesn’t fit before the slot is cut. I’m not sure what they were thinking. They should have had a relief cut in the bottom.

SS will have the best advice. This is a real shot in the dark, but could it be the single blade? Do you get the same results if you put both outer blades on it?

I would also suggest calling SawStop customer service for advice. Will the saw run in bypass mode for this one cut?

Do you actually have the riving knife installed? If the riving knife is part of the problem you may want to remove it completely, especially since the riving knife really doesn’t serve any purpose when using a dado blade. (I don’t have a SS, just an observation).

I really doubt that he has the riving knife installed. Perhaps, but I can’t imagine why. The knife is for a 10” blade and he stated he was using an 8” dado blade. Sawstop makes a special cartridge for use with 8” dado stacks. It is taller to position it properly next to the blade. I have one and use it frequently with my 8” dado blade. Never had any problem like the OP has described. Fred’s comment is interesting. I have never tried it with a single dado blade.

Looking forward to hearing what Sawstop has to say.

One thing that can cause calibration failure is if the riving knife lock is left in the up position. Even if you don’t lock it all the way down it won’t calibrate.
Put on at least two blades on and make sure the riving knife lever is all the way down. The saw needs the mass its computer is expecting to give the green light.

Hardwire the motor to the starter and be done with the project in 44-55 seconds instead of hours. As a bonus you’ll end up with a more reliable saw with fewer failure points.

Maybe a stupid question but, can you just bypass the brake? If this is for a single cut and you can just turn the safety feature off, I’d be a whole lot more inclined to do that than to continue trying to make it work. Either way, good luck and stay safe!

Is it a Freud Dado by chance….I know this sounds stupid and don’t know if this applies, but the freud dado is notoriously out of of round and really only causes problems on the saw stop.

Dado, at a 45° angle, cutting thru a ZCI? Um, either I misread the post or something is stupid here. Maybe the warning is correct and not an ‘error’ to be bypassed …

Sounded to me like he wants to use one of the inserts fora bevel cut with a regular saw blade, and was trying to work around making the slot.

Bypass won’t work because the saw won’t recognize the blade and brake are properly spaced.

Correct above, trying to make a 45 slot in the insert just so I can make 45 miter cuts. Standard 10” blade is too large for the initial 45 slot cut.

This is least of my problems not.

I think a blew a capacitor. I’m getting no lights now when plugged in and turned on.

Calling customer support when I get home. Hope is just capacitor. Don’t think mine has a reset button anywhere. I looked.

I just realized that you didn’t say which error code you were getting.

Update: Motor is fine. Since I couldn’t get the dado blade to work I thought, screw it, put the regular brake in and blade, crank it to 45 degrees, put the throat plate in and camp it down with a 2×4 and flipped the switch. It’s a 5hp what could go wrong…...well 3 seconds it it bogged down and smelled bad. I thought I was in for a heft $$$ repair. Sawstop couldnt figure out why I had no lights. As I leaving the garage to hit the gym to blow off some steam I forgot we installed a sub panel for the saw power line. Checked panel and it the breaker was tripped…..YES YES YES! So the motor is fine.

So the motor is fine but I’m still getting brake adjustment error code.

I thought I had it this morning. I cleaned the 8” dado blade with acetone thinking it’s a connectivity issue. Adjusted the brake so it’s nicking the head of nickel. Flipped the switch and got the green light. I cranked it over to 45 degrees, still green light. Put the infinity insert in, put a 2×4 on top to help keep insert down and cut clean. Started cranking up and going well. I got nervous, turned it off and wanted to check how close the cut was to the aluminum throat plate. Looked good. Put the insert back in, flipped the switch and now it’s giving me brake adjustment error.

I then put a standard brake in and 10” blade and was it fine, then I cranked it to 45 degrees and brake adjustment error came on.

So That’s where I’m at. I’ll fiddle with it for a little bit but can dow the 45 cut on my router table if needed. Would be nice to be able to do dado cuts.

I’m calling Sawstop again monday as the issue isn’t lack of power anymore. They were great when I called yesterday and walked me through and emailed me a step by step on resetting the saw. But I dont have to because I got power and lights.

FYI: ICS and CB model sawstops don’t have external reset. They are inside the paddle control box. Mine is a 2005 and initial diagnosis was a their updated board and contactor $300 and possibly new motor $500. It’s not the motor but might still be the internal board or possibly something with the brake sensing.
