I have just bought a nice new Sigma 3E3m, I love Sigmas but this one is not quite right. When you put the measuring bar into the machine and push the locating pin to set the bar for straight cuts it is about 3mm out of line over a 1200mm tile. I have to get the square out of the van to set the bar each time i use it. In some ways it's no big deal as at least i'm sure of a nice even cut. But then again it is a premium price cutter that I would expect a nice straight cut by using it's own locating pin. Has anyone else had this issue??

Not with mine. Sorry for stupid questions but are you holding down the location pin (sprung) when you tighten the lock arm? Also - if there is any debris in or around the hole in which the measuring bar sits in the main frame, this can effectively "bend" the seating of the bar and mess it up.
It's the only weak point I've ever found in Sigma's design.

Not stupid questions at all. I did think of all your points as well, all my other sigmas are perfect. Gutted. It might have to go back to the shop. Not sure of the returns policy on these machines though.

It just needs tweaked slightly. There is a bit for tuning it up as my 3D was running out.
My 3E3M came out of the box almost perfect.

How do you tune it up???

On top of the locating pin there's an Alan bolt & a nut, this can be moved round to turn the measure bar slightly.
It's a pain to do, it will show you in the Sigma booklet if you still have it.

Dam it i threw the booklet, i'm sure i'll be able to figure it out though. I'll have a look tomorrow. Cheers for the advise.

All of my Rubis had this problem straight out of the box........then again they are Rubis! The adjustment on the sigma sounds like that on the Rubis which is easy enough to sort

It's going to be the first job in the morning. I'll post back tomorrow eve how I get on.
