I enjoyed reading your post. I hope more people come here requesting work.

Thank you for the compliment. The prints they did were not constant in quality. To have there print representing my work was disappointing. I emailed them and they added more photos that I took. They responded promptly and professionally. I am not convinced that it was rigged the design that won was...

A little resin in the guide rails can cause the x motor to jam. Cleaning and oiling the rails worked when I had a problem. I also removed the red plate that the vat sits on and cleaned it.

https://myminifactory.com/object/tim-s-heart-5437 free download I printed this with cherry 30xy 30z. Default settings should work great. Print it with no supports, flat on it's back. During layout lower its z position so it will have more contact with the table on the first print. That is only neces...

Do you hear any clicking noises when you raise and lower the table?

It sounds like the z axis is slipping but it may be sticking as well. I would check the connection between the motor and the lead screw. If the screw that hold it together is loose the motor will turn as it should and the lead screw will move less than expected. When using the toggle it will appear ...

I found that if I bend the sweeper I can change the angle that it is at in relation to the vat. Bend it left or right and it will change the way the rubber part contacts the vat. Mine was skipping and this was an easy fix.

Just making a wild guess. Change one of the two?

It could be the computers display settings but I would check this. Open the B9 software, settings, printer manager, projector's video port.

That will not solve most problems with the model peeling off the table. I did it because the bottom of the model was curved and snap to the floor. If you have a cube and snap to floor it should be good, if you do this with a ball you will not have enough contact on the first layer. If half of your p...

Do you re calibrate the table when you switch from one vat to another.

This is very interesting.

I was thinking the out side. A little dust won't hurt, but a lot will. My thought is resin on the lens will block light. I know for a fact a hair in the pdms will show up as a line on your model. If you were to get resin on the bottom of the vat that should also be a problem. Do you have a second va...

I printed it laying flat on its back. I set the z position to (minus) -.05 to increase the volume of surface contact on the first layer. The model set down to zero but the curved surfaces give very little to cure on to the table.

Three other things that could cause this. Something on the lens of the projector, the bottom of the vat or in the pdms. If you have another vat I would swap it out, and look at the lens.

Happy Valentine

I run a B9 1.1 on a 10 year old lap top. Lay out and sliced on a different computer. It did not work for the B9 1.2. More than likely I could have got the hardware to do the job, but the video card was not designed for the aspect ratio needed. It is nice to do it all on one computer and well worth t...

I picked up a $300 asus lap top from best buy. It slices slow but gets the job done.

For this ring I used the B9 1.2 to create the model.
