Hi.
i was a GC service enginneer for three years.
What surfacing programme do you use and what blocker do you have?
thanks

I think he has resolved the problem.
I was going to up the temperature on my chiller to see if that would help since it's ice cold constantly and wax hardens in the spout.

It sounds like the nozzle could be touching the chill ring. The nozzle is supposed to protrude through the hole in the chill ring, but not touch. That keeps the nozzle hot, but the chill ring cold. Even with an ice cold chill ring, it shouldn't cause the nozzle to clog.I was going to up the temperature on my chiller to see if that would help since it's ice cold constantly and wax hardens in the spout.
You may want to verify that the little heater on the back of the nozzle is working as well.

We have the same problem. What I've found is that some lab techs at my store have a problem blocking a lens correctly. Wax has been pumped outside of the chiller ring, in-proper pressure has been applied to the arm, etc. A few things to look at, when the elevator takes the block down, push it down just before lens moves over top, I've found that a lot of mine do not go all the way down, causing prism. And on progressives apply a little pressure to the bifocal area while pumping wax onto the block. This will reduce the amount of unwanted prism, and at my store at least, a huge decrease in vertical imbalances for thinning prisms. Check the chuck on the SGZ, and possibly check blade? I've found 6flute seems to do best on a 50/40/10 (poly/cr30/trivex) lab
Hello!
Well, I'm not sure if the problem has been solved, since it has been a long time since it has been posted, but I used to have the same problem. We solved it by erasing the prism by pressing 'clear' or F3 on the Prism powr and Prism Angle options. It worked for me and I haven't had any problems. Hope it works for you too.
Hi
I was wondering... Since we acquired the SGX lite we've had little differences with the prescripcions. I mean, they are not always perfect. It sometimes have a 0.25 more or less than it should. Sometimes a 0.12. Is this normal? or are we doing something wrong?
With the step one when i install new elevator plates i always take a rough fining pad and sand the steal pin a little bit otherwise our blocks don't always seat correctly. Other things to look at 1. is the spring in the suction cup stretched out? with the automated versions of this blocker if there is a fill time out and the tech doesn't catch it the blocker will attempt to pick the lens back up stretching this spring out. 2. I have also seen broken reservoir mounts causing the lens platform to tilt slightly when leaned on. 3.Check the center screw under elevator plate to make sure it is tight, i check mine every other day as they tend to come loose and not be discovered until you have prism in 40 jobs.
