or do you mean the motor itself is loose?
if that is the case tighten the screws holding the motor to frame.

Mark,
You have to check that the hex bolt is tight on the arm that is attached to the motor.
It needs to be set in a position so the screw tightens on the flat part of the motors spindle.

thanks for attention and answer.i test your model its ok becase the last layer of print is on silicons surface and nutrally is flat and smooth.my problem is one layer of print that one of faces is in resin liquid...that face isnt good and flat surface i think time of resin cure is long...all of my ...

How are you setting it up to grow?

can you show us a screen shot of your layout?

Have you tried to print using the new printing number? It isn't that much difference that you could notice other than a model you have printed in the past might take 5 minutes of more less time to print. only answer is if you upgraded to the newest software and your not satisfied then go to the down...

What printer?
if it is a 1.2hd or 1.1 printer then you would need to look at the pdm for fogging.
next check the focus it could have got bumped and calibrate the build table.

Thanks Mike

Thanks I will look it up.

Oh, and you don't need an Ishor system to refine. I suggest instead understanding the chemistry so you can figure out what to do. There's a book in the internet written 80 years or so ago that teaches jewelers how to refine. I can't remember the author's name right now. But when I get home I'll loo...

excuse I wanted to say that DURAVAT of the machine was damaged, and I wonder if someone indicates where to fix because I would not like to buy a new one. There is no instructions to fix a damaged Duravat that I know of. The only option that has been offered to us is if it is damaged B9 will sell yo...

Yeah.. must be my caster for sure. Everyone else I've talked to say they are getting perfect cats with b9 emerald.. The 3 or 4 people using b9 emerald with my caster have similar problems.. tried just about suggesting everything to my caster but to no avail so looking for a wax like resin that does...

Very true Robert, thank you. We've maintained our 'normal' burnout schedule that we were using for hand carved waxes. I don't do the castings in my shop. The detail is surprisingly very crisp even showing 0.6mm milgrain. We were using the emerald and the yellow resins previously. Both seemed slight...

What are you talking about??

You say you don't have to cure it? Awfully dark I was expecting a lighter color how did it cast ? any pics ...
