Can't get square cuts with TS75 and TSO guide rail

I am fairly new to wood working. I had started out with Ryobi and started to upgrade to other brands. I recently bought a TS75 and tried to square the track with a square and it worked pretty well. I figured it would be nicer to have the track square so I went and bought that.

My cuts are less accurate than before. I did a 5 cut test and over 23.75" I was off by 3mm. As I was putting the track on top for the last cut I could see a huge difference and I cannot figure out why. I tried to clamp the track on each cut and did it a second time without clamping. Results were better without but not by much.

I did use multiple squares that are all square and put them up to the TSO guide and rail and it is sitting square. I also made sure to lift the track before putting saw down in case the non skid was preventing the track from sitting correctly.

What else can I check? Thank you
 
Are the cuts straight?  I remember some people having a slight curvature if they plunge directly into the ply instead of approaching it.  I'd check and rule that out first.
 
I think the rail squares need some practice to get things right. Depending on your cutting situation, you really have to make sure that the rail and square is pushed against the stock. Putting your saw on the rail, moving it on the rail, slight kickback, clamping the track all might slightly move things around. Push against the back of your rail multiple times to make sure everything is correct. I like to slightly lean against the back of the rail when I start the cut to make sure that it's pushed up correctly. All this is more relevant for smaller or less heavy stock...
 
What woodferet said... The rail square is only referencing from a short section so make sure your first cut is straight.  With melamine I was having trouble with the material bowing after I would rip cut a full sheet and released the stress.  I thought my long rail was bowed at first.  I will say I wasnt a huge fan of the rail square.  I too had trouble getting good square cuts and the other thing that I hated was in order to crosscut a 48" or 49" sheet I could only put it in part way otherwise it made the rail to short.  It was good if you wanted to trim off the bottom of a door or something that wasnt 4' or super critical. Otherwise it just hung on the wall... For the most accurate cuts I found a 4x8 mft style bench with a fence worked best
 
[member=73890]aswad123[/member] - welcome to the FOG – and thank you for your GRS-16 Guide Rail Square.

Quick first step: have you seen the very detailed GRS-16 USER GUIDE?

If not, it is available  24/7 on our TSOproducts.com SUPPORT site:

If, after practicing with the recommended procedures and using the Trouble Shooting Guide, you still have problems, contact us directly:

Thank you all for your responses.

The cuts are straight and I am not plunge cutting. I took all of the tips an have seen much better results.

I did practice at setting up quite a bit and it seems I need to take more time setting up. I have done several pieces and was able to get it very very close to what I believe would accurate. Using a stop of some sort at the far end of my board seemed to help a lot. I hadn't done that previously.
 
[member=73890]aswad123[/member]  - way to go !
Glad you persisted. Is there anything we can improve in our User Guide? - or demonstrate in a video clip?

Like you, I'm fairly new to 'accurate' woodworking and was having similar issues albeit with a different brand of rail square.

I watched this vid=GosforthHandyman  which sorted out my issues completely. The only thing he didn't do was to remove the factory edge first. That could still throw your cuts off.

Good luck.
