SFA: What's the Answer?
Uneven Backsplash Heights
Dennis Cunningham
Dennis Cunningham
We have a Park Fusion & Park Saberjet.
Eric Hartman
Cody is correct. I’ve operated a Park Fusion and a Northwood Sawjet and both have the same issue. Cut splash all in the same direction.
Ryan Louis Schroeder
Eric, glad to know we got that figured out!!!
Eric Hartman
Ryan, I was waiting for you to tell me how to do it.
Caden Isenbarger
We had this issue a couple days ago. We recalibrate the saw and reset the zero on x and c axis. Hope this is helpful!
Douglas George Hogue
Feed rate, order of cuts, calibration.
Jason Anderson
As a polisher we despised the CAD and SAW for not calibrating straight lines and we had to manually polish them down sometimes by a half-inch for 6' long. Ugggg.
Josh Simmons
I run a Park Fabcenter and, regardless of calibration, it will do that! I just started sawing all my splash going in the same direction! They come out perfect!
Dennis Cunningham
This is one of the recommendations that I am not sure we have tried.
Josh Simmons
It sucks but it works for me!
Dennis Millsap
We do the same thing with our Fusion. Cut all cuts same direction. We do all of x or y then do the other. Unless it's quartz; then we just gamble if it's something we have to cut a certain way.
Josh Simmons
It really makes me cringe sometimes sawing quartz when you cannot saw it the way you should.
Nick Comerci
I put a small gap between the backsplashes rather than common-line them, and cut the heights first before cutting the widths. Works great. But having the right blade is also key.
Dennis Cunningham
Nick, this is one of the recommendations that I am not sure we have tried.
Brian Dearing
Never-ending struggle.
Christopher Addis
Sounds like a common-cut issue.
Kevin Colt
As a fabricator nothing is more disheartening then finishing the top and going to the splash to see this lmao.
Marko Picard-Tahourenche
Is your blade bending? Are you pushing it a lot? Maybe try with a reinforced core.
Matt Pelton
Usually if your saw is out of calibration, it will cause this. If your blade is .003" out of square on the C axis or your bridge is out of square by .005" your splash can vary upwards of .125" without question. I would recommend using your dial indicator and inspecting and the straightening your equipment.
Mark Lauzon
Quartz has tension sometimes … mind your order of cuts. Parts can move as tension is released.
Erick Gonzalez
Blade kerf. Is it actual .125 or .133 or .135? Not having the correct margins for common line cut if you are using SlabSmith , make sure your CAD software has the correct blade kerf as well. Condition of your slats and backerboard? Is your table level? Are you cutting too fast to where the piece is moving? A lot of variables.
Veronica Flynn Grieve
Definitely check you table slats/bed.
Brian Lindbloom
There are many causes to this. Proper tool set-up, blade quality, material quality, machine health, machine calibration, etc. Give us a call at Park if you need some help going through anything on your PC or on your machine.
Dennis Cunningham
Thanks Brian. I am with Chivino in Phoenix, we are 100% Park Industries. With all our growth and added personnel we may need to get you guys down here for a refresh.
Brian Lindbloom
Definitely reach out if you need a field service tech out there or if you need additional training. We offer Proguard service programs as well as different training options. https://www.parkindustries.com/
The struggle is real …. We are a fully automated shop ran by some of the smartest people I know but sometimes this is the result. All splashes programmed at the same height, but this is the result! 4 splashes at 4 different heights …. How are other shops avoiding or managing this problem?
Matt Lake
We run a Park Saber and when this happens it is usually a calibration issue. Usually happens as a result of a common line cut and the blade width not being exact and then the saw turning direction and either adding or losing material because of the incorrect width set up in the computer.
Melvin Triplett
Blade is walking along with a calibration issue.
Dennis Cunningham
Melvin, thought of that but wouldn’t the splashes be tapered?
Melvin Triplett
No I use to set plum and trim to zero on both and your situation still happens . If you don’t run at correct speed along with rpms it will always happen. Plus, it’s how well your saw table is stable. Some stones just make this situation happen. If you look at your splashes, they go in a slope direction, and when the blade turns since the calibration is off the sizes are off because of the damaged blade. Put on a fresh blade and calibrate well. This will correct the problem.
Wes Davis
If you’re fully automated, why is your saw cutting different heights, unless the guys are running them through a backsplash machine multiple times.
Dennis Cunningham
Wes, that’s the question.
Wes Davis
Cut splash all the same direction on your saw. Don’t let the head rotate. If your kerf setting is off at all, it will mess things up.
Cody Beahm
We ran into this. It happened when we ran the saw blade left to right vs. right to left. We have a Park Saber saw
Marcin Danecki
Make sure the blade kerf is actual and avoid common lines when cutting backsplashes.
Kyle Scoffield
We stopped common-lining splash and that seemed to solve most of the issue. Also make sure the backing that you lay the slab on isn’t too beat up or shit might shift around as you cut.
Michael Jamison
Common result with man-made stone.
Alex Bores
Each splash to be cut individually. As you are probably having pieces move, and kerf of blade is coming into play.
Curt Sample
Could be kerf adjust needed. Probably different on each side of the blade. Had same issue a bit ago.
Lee McFadden
Is it bowed or is the saw cutting it at different heights? Is it only in 100mm strips that it’s doing it? Is one end of it 95mm and the other end 100 as in tapered? Just watch the machine that it isn’t actually pushing the material or sliding off if the slabs are bowed. Certain quartz brands I’ve cut can swell sometimes; they don’t actually move on the bed but they do swell. I’ve never had the problem that bad so I’d nearly put it down to the saw needing calibration (shouldn’t apply if the rest of the worktops are ok). Be interesting to cut them manually if they do it and if they don’t it’s more than likely calibration.
Bobby Leaptrot
If the dimensions vary depending on the direction of the cut, there’s a good chance your calibration is off.
Victor Swithenbank III
Bobby, I'm pretty sure this is the issue. I've been here.
Michael Gilani
It happens with some material that is well-compressed. It actually moves on the saw while cutting the middle of the slab. That’s why we always cut the splashes from the bottom of the slab then up.
Tony Neylon
All digital saws do this if the cuts run opposite ways. Orientation of cuts should mitigate it.
Victor Swithenbank III
Make sure your saw is dialed in beyond expectations.
Bobby Pfeifer
We deal with this issue from time to time. We set up a calibrating wheel on our Wizard and gauge down the splash till they are all flush.
Kane Ireland
Had this issue come up when the saw is running in different directions for the top and bottom of splashes. Something that could be resolved with some calibration tests I'm sure, but the quick fix for us was just keeping the saw cuts running in the same direction on splash.
Josh Hartzog
I’ve seen this caused by a few things. Kerf calculation should match what the gap is on the table and not the actual blade width. C-axis center could be off and if cut in different directions could cause this. Narrow it down and check your kerf is correct. Then check order of cuts or test it by cutting a 12x12 in different directions/same and measure the two to see if turning the head gives different sizes. Or pieces may be moving. Cut the longs first and cut ends second.
Rene Ruiz
Saw jet are garbage when it come on backsplashes. Need calibration every two weeks.
Chris Black
Adjust your auto align on AlphaCam. or calibrate your saw.
Fabian Delarosa
Running too fast, slow down. Non-sawjet user about to start talking about sawjet 😂😂😂😂
Jadon Sumthing
Also check the pivot point on your saw as it can affect this as well. If your pivot is off it will cut different sizes depending on what direction the blade is running.
Franko Deita
I think it's your table lol.
Chuck Clemmer
You cutting them first?
Matthew Paul Schumann
Also if your table is not perfect they will move a slight bit. Must be level and flat.
Clay Millsap
Cut order all day.
Dustin Wallace
Parts moving, or pivot, exact blade measurements and dialing in the saw test, and a dial indicator. Easier said than done, especially if you use a multitude of blades it can get away from you.
Ritchie Otero
Calibrate your machines.
Mark Stivers
Slow your saw down. Looks like it could be cutting too fast and torquing the blade, resulting in different heights.
Halil Musalar
If you give edge line polisher because of pressure some ones become less in height.
Brett Eaton
Order your cuts from the outside of the slab in.
Tony Anglin
Your slabs needs to be cut on a rubber-topped table. Timber may be bowed or convexed and slurry is gathering underneath the slab, and when the weight of the slab has depleted vibration moves the slab, I think.
Timothy Taggett
Never go off saw measurements. Always self-measure splashes for best results.
Brandon Lantto
Tune the height with the Fastback..
Dennis Cunningham
Brandon, that’s what we are doing now, but there has to be a better way than fixing the problem caused from the other equipment not operating correctly
Lee Martin
Shims.
MP Olivas
Join parts with the blade kerf.
Jack Davis
Hmmmmm…big investment for that to be happening.
Alex Bores
It’s direction of cuts. You have to cut from same orientation on each piece.
Chris Holland
Was it cut on a saw jet with slats? If so, order of cuts and where they are cut at will play a huge role in this.
