Mark,
That looks great. BTW, plastic is safer than metal to have around the blade. Are you having the parts milled (i think you mentioned AL) because some portions of the design are too thin to be robust in plastic?

Mark,
Unfortunately it is true that the blade tilt axis is not fixed, you use the term zero tilt. The saw unit is hung at the edge of the cast iron from 2 pins (one in front and the other in rear). Not sure if this arrangement is incompatible with zero tilt or not. Sometime ago it occurred to me that I should check with blade fully elevated, may be in that position it is zero tilt but I have not checked.

The white blob is silicone, looks like they filled most of the internal pockets of the factory section with silicone, to hold it in place and to diffuse the light. The LED’s don’t even line up with the holes. The gray parts are the factory supplied parts.
Yes the first step was to redraw/ model the exact parts that felder supplied to their dimensions, i then extruded down about 8mm for the wood insert and add the tap locations for the bolts to hole the wood insert. At that point i had to extrude pockets on the backside for the LED wiring and there is a little metal dust shield that required space relived, there are some other minor tweaks that were required to make it work.?
When I bolted on the 3d printed part it actually lined up dead flush with the cast, I would prefer a little adjustment so I had to drill out the washer of the bolt that holds the part onto the cast by .5 mm and that dust shield, had to file a flat on the washer so the part could have a little room to drop below the table if needed.?
I was resisting and really wanted to just buy it so I could get back to building furniture but couldn’t take the random flying pieces of wood anymore, One of the big drawbacks of a zci for me is that you have to remove it for angle cuts but yet in another plus of moving up to the k940 over the k700 is that you don’t have to remove it to change the angle, at least with a 300mm blade which is what I use.?
Felder should offer it but I think it would be pretty costly, they could recut the mold for the Injection molded parts but the parts they are getting out now (at least the ones on my machine) are pretty low quality, lots of shrinkage probably due to injecting too fast, cooling to fast I doubt they did a a flow analysis- could probably improve the part with scientific molding but even then plastic isn’t really the right material to base a ZCI off of for this machine config, could be done but metal as the base would be better.?

I need one terribly for K975. I bought 2 for KF700 and never installed them. It was not bad because I do not have scoring. I think scoring just exacerbates the situation and cutoffs are violent. IMHO, OEM should consider ZCI implementation when designing the saw.

Re: Calibration of power drive angle
My understanding is the hard stops are set within a certain distance from/near the limit switches if the hard stops are set to far the motor actually has enough power to pull the brackets off at the welds - or...something like this.? Thanks for the info on that Dave.?
Lucky, maybe I should have included the procedure, I am only familiar with this a little as I run a software validation team for control software which includes encoder motors, basically you show the software different points (sometimes specific points) on the encoder typically the more the better so it can resolve itself. The display is totally passive and is just showing what the motor sees
Attached is the procedure?

Like you and Lucky described, I do the cut test to confirm calibration. I calibrate with precision 90 & 45 squares.
I am just curious what my wixey angle gauge does. If memory serves me right if I zero it on the table it shows 0 or 90 depending upon which side I use on the blade.
I do not like using digital angle gauge for calibration because, well it is digital; you do not know when it is going to flip plus it does have repeatability error.
Imran ? Imran,?
For the 90° stop, I cross cut a 1x3 on edge with the blade fully up, flip the off-cut over, put the two pieces back together on the bench and check with a straight edge. ?Same method with a 1 x 3 at 45 and check for square.

Re: Calibration of power drive angle
Hi Mark:
My assumption is that if 90 and 45 degrees are good, the software ought to be accurate enough to get all the angles in between. Maybe I’m being naive?

For me, making test cuts in timber and measuring the results yielded the best calibration. 90 degree cuts in two thickish pieces, butt together and check with a straight edge. 45 degree cuts and then check for square.?
I’d be interested in whether the tilt box works for you. Cheers.? ? I have the procedure, is a digital tilt box accurate enough or am I better of using a vernier scale protractor like the Mitutoyo 187-201. Looks like the tilt boxes are accurate within .2deg.

Re: Job site saw recommendation?
Anthony
I would check out Bosch's latest offering. I have used two different generations of their jobsite saws, and it exceeded expectations as we do house trim and kitchen installation for Habitat. The fence, riving knife, and extension table just seem to reflect a quality that we come to expect on a cabinet saw. I assume several brands are made at the same factory these days, but I have found myself throwing yellow power tools away in the last five years. The reliability has been disappointing, but they have been primarily battery tools so it may not be relevant to your search for a jobsite saw.

Re: Calibration of power drive angle
Thanks guys, what about the other angles 11,2°; 22,5°; 33,7°? I know about checking the 0 and 90. They Also told me not to adjust the hard stops which makes no sense to me, the encoder motors we use at work utilize hard stops, we don’t like to rely on the software for that

? Thanks David,
Like you and Lucky described, I do the cut test to confirm calibration. I calibrate with precision 90 & 45 squares.
I am just curious what my wixey angle gauge does. If memory serves me right if I zero it on the table it shows 0 or 90 depending upon which side I use on the blade.
I do not like using digital angle gauge for calibration because, well it is digital; you do not know when it is going to flip plus it does have repeatability error.

For the 90° stop, I cross cut a 1x3 on edge with the blade fully up, flip the off-cut over, put the two pieces back together on the bench and check with a straight edge. ?Same method with a 1 x 3 at 45 and check for square.

I guess i will need to check my angle gauge now. I did not use it to calibrate 90 & 45 stops on the saw though.

Re: Tannewitz Blade Guide choices
I was able to reach Tannewitz by phone as the set of hardened steel blocks for the upper guide was $140 so I ordered them.? A pair of regular steel
blocks for the Carter was only $22 so I am going to try it for a while to see if I like it…joe

I think WWTW sells parts too.? There might be some prices on the website for comparison.? Dave
I decided to try the guides that came with the saw, the Tannewitz on the upper and the Carter on the lower.? I have ordered new wear blocks for the
two guides and I have new rear bearings for both.
?
?
Did you try Woodworkerstoolworks?? I have Wright guides on my 217 and Y20 and like them a lot.? They do support the blades well although I have resawed without any guides.? Dave
The parts guy at Tannewitz expressed a strong preference for the old style blade guides.? He said the steel block style support the blade in two places
and they contact the width of the blade.? The bearing supports in one place and the bearing face is narrower.
?
The machine I bought has the Tannewitz for the upper guide and a Carter CP10 for the lower guide.

My Tannewitz came with their old style blade guides with steel wear strips.? Tannewitz now uses ball bearing type guides. I've emailed asking for pricing replacement wear strips and on new guides.? I did see one place selling replacement
wear strips and the set for upper and lower were like $700 !? To put things in perspective, the rear bearing on the original guides in 3" across. I found one new rear bearing assembly on ebay for like $70.? But I will need a second and all new wear strips.
I've been using Laguna ceramic guides for 20 years. I intend to primarily use the Tanny for resawing and plan to mount a resaw feeder to the table.

I made the simple mod to the hood. I may drill and tap additional holes to get the fence over even further.? I have always hated routers and always
had a shaper so my view is skewed ?

Thanks Joe. Luckily David Best suggested that I keep the stock fence plates when I upgraded, so I still have them.
Since I have a router table, I'm wondering if all the switching time is really worth it. I think not, for most?jobs...

Bill, if you don’t modify the hood as other described you need to use the Felder plates.?
I ordered my machine with the Aigner option and they shipped with the Felder plates too.

Thanks Imran. I have the router belt, it only aligns with the third pulley on the motor.
The router spindle is unlike the shaper spindle and has only one pulley built into?it.
I’ll check the threads for John’s mod.

?So yesterday I needed a roundover on a 1/2 piece of oak so I figured this is great time to try my new F700Z as a router.
First thing I noticed is that the belt will not fit on the lower motor pulley as shown on the placard on the front of the machine where it looks like you'd get 15,000 RPMs.
It will only go on the 3rd one down.
Second is that with the aigner fence, It will not go back far enough to get to the bearing on the top of the roundover bit.
You cannot use the full bit.
I'm wondering if the original Felder fence will facilitate that last 5mm of travel?
Thanks in advance

To me, in way of prioritizing the trouble shooting, I would work on the table saw motor cabling. To be precise, the part between selector switch and the disconnect where you isolated the different motors.
Your trouble shooting points to this section of wiring having the problem and it moves from table saw motor to shaper motor and both motors are fine otherwise.
