Software Update Clarification

Post#1 » Wed May 11, 2016 11:25 pm

Hi All,
I just updated the software and started a print. For some reason, there was a warning on the panel that my settings used are not the standard/default. I did not select 'use previous print settings' either.

Question: Did the order of projector light fading away get flipped? I remember the projector light used to fade away near the end of each projection. I had time to slowly let go my hand while pressing down on the build table for the first two or three projections.

I print mainly at 30z, 30xy, Cherry/Red resin. Do you all print using the standard settings? I don't ever remember adjusting the settings but for some reason the print settings panel tells me I'm not using default settings. Maybe I did adjust but don't remember

I only noticed the default changes warning. All is good with my update so far. Love the new slicing speed.

yes, the slicing speeds are super fast. Surprised me when it took about 20 seconds to slice a file. It usually takes 3 mins or so.

Print is done and it came out all good.

I'm still confused about this note on the print panel "Caution: Standard Print Cycle Settings Not Utilized"

Should I select and ask it to use the default the Red/Cherry 30zxy default settings next time?

Yes, go ahead and click to restore defaults if it comes up.

Hey, what are the pegs on the new calibration prints supposed to measure ?

The squares should measure 5x5mm. F+ and F- sides should be 90mm spanning from left square to right square. B+ and B- sides should be 50mm spanning from from top square to bottom square. *for 50 microns

I also got that Caution message, and I noticed that the values for Pre-Release Lift and Overlift Cutoff were modified. Changing from 0.30 mm and 1.50 mm to 0.1 mm and 0.5 mm respectively. The print time was also reduced by 1 second.

I'm curious: What do those settings control?

Pre release lift is a lift before the vat makes the release move. Mike states that with full build areas, particularly in the 50 and 70 xy configuration, that this will aid in lowering the force needed to move the last layer printed over the dam.

Prob should override this with items with very fine details as it could damage the print.

Here is Mike's explanation:

"The default pre-release lift option lifts the build table 300 microns right after the exposure & kick time have elapsed and right before the vat slides right to release. This is helpful to relieve downward pressure on the vat and can allow it to slide easier when there is a large object being printed. It’s possible (haven’t seen it yet) that the pre-lift might damage a VERY fragile print (think stem cell lattice, not ring prongs). In that case you can set it to zero and it will act like it used to (no pre-release lift)."

There shouldn't be any issues with slicing using the new software and printing using an older version, right? I was reading in another thread that an older version of the software is better for very small items with very fine details due to a feature in later versions intended to reduce z-bleed. (The original poster claims it does reduce z-bleed in larger items, but makes it worse in smaller ones.)

I actually do my slicing on a different computer than I print with, so I wouldn't be running two versions on the same PC.

The format of the job (.b9j) file has not changed so you can slice with the new and print with the old software without any problem.

The z bleed correction will not make z bleed worse on small parts, but it may cause very small details to fail. This is because they are too small to survive the printing process at the correct size. The old software allowed z-bleed to enlarge them enough that they would print. But that could also be done by enlarging them in the original design.

We can only support the current version of the software and if you are having any issues but not using it, the first thing we will do is have you upgrade. It contains numerous improvements, material setting updates and misc. bug fixes. There's really no reason to use the old version.

Hi Mike,

I spent a fair period of time earlier this year going back and forth with B9 support to determine that the z-bleed correction was causing significant failures with small elements in my models when using black resin. I am still using version 1.8.0 for printing because of this. I have since confirmed that these delicate features will print at their intended size without appreciable "help" from z-bleed by adding additional pigment (z bleed reduced by about 80%), but only with the old software. In my discussions with Matthew, there was mention of a switch to disable the z bleed correction feature being added in the future. Is this still in the works? If not, can it please be put back on the list?

Could someone please post the old Calibration Print files here for my own curiosity ?

looks like all the older version of the calibration files were replaced with the newest update to the software.

I have a couple of the original ones in my print folder. Not sure how to send those type files (sliced and ready to print).

Out of curiosity, why the change to fading the image instead of fading it out?

I think it gives a more even "final cure" on the layer.
