Hello everyone, I recently bought a kapex but unfortunately wasn't able to test it out within the first 30 days to be able to return it, ( even though from the date I received the tool, it had only been 28days ). I didn't buy the saw to return it so I decided to have festool fix the issues with the saw. No matter what I did I couldn't get vertical or horizontal square miter cuts. I just got the saw back on Friday for the second time after the issue had been supposedly repaired but I still cannot get square cuts. Not exactly sure what to do so I thought I'd ask here to see if someone else had a similar experience with kapex. Considering the cost of this saw, this is very disappointing. Appreciate your feedback.
 
When you say square cuts are you referring to issues with top to bottom or front to back of a workpiece? It would helpful to know.so that answers will be appropriate.

I had the same problem, my blade was bent. i put the blade on a flat surface and used a feeler gauge and determined i bent the blade when using my Kapex without
a zero clearance fence.
I'd use a magnetic angle box on the blade to ensure a 0 degree plane. Then i would figure out the base...... Good luck

Appreciate the suggestion. I will try that, however, I have only had it for couple of months and It's gone in twice for repair, you would think that they would check the blade as well. Either their support is incompetent or the there is a manufacturing defect. I still cannot get square cuts. I will keep sending it back until they fix this tool.
 
As u wish. I'd use a Wixley and make a 90 degree cut and check for Square, plumb etc.
Your Kapex should cut it perfectly. Maybe post a picture of your cut and use a square showing which direction it's out?
I took some pictures, not sure if this what you were talking about. This is how it came from Festool after repair...I have not made any adjustments. I did call them but was rudely told that it was fixed when it left the repair facility.

So the blade isn't square to the fence when you cut the plywood? That's odd. Thanks for the pictures
The fence is not 90 degreed to the base. there is a variation of degrees from right to left. It could just be the fence that needs to be replaced
 
Time for the obligatory-from-me caveat that while the angle cubes are handy, they're not uber accurate. Wixey itself only claims +/- 0.2º accuracy, with repeatabilty at +/- 0.1º.

Your squares are much better than that. Personally, I'd use a good 1-2-3 block and feeler gauges to check fence to table and blade to table squareness. But, for cutting plywood flat on the table, if your fence is straight (good straightedge with feeler gauges to test) than it's just the miter angle that needs to be tweaked.

However, @Zafar 's comments seem reasonable - the fence might have a twist in it, which affects not only in the horizontal plane, but in the vertical planes as well.

I wish I could comment on Festool's repair service. For other manufacturers I'm sure they'd say this is within specs, since they sell their SCMSs for carpentry use, not furniture making.
