Initial Layer Not Sticking To Glass Print Bed

I use this as a protective layer in front of the lens glass.

This is the first time I’ve gone for a Sigma lens, previously sticking with Nikon and Zeiss glass. Simply put, I’m floored by the build quality of this lens and the images that I’ve gotten with it so far are incredible. I wanted a fast lens in the 35mm range as I often shoot night grape harvests in the Napa Valley. This will be a perfect addition to my kit as it balances perfectly with my D850, focuses accurately and FAST! It will definitely be in the vineyards with me next harvest. In the meantime, it will get some landscape work and we will see how it stacks up against the Zeiss Milvus 1.4 25 mm. I think it will do just fine.

This is great for a glossy print that I had to send out to a friend. To keep it from sticking to the glossy print, I used tissue paper to wrap the print and then it slid easily into the protector

The da Vinci Jr. 1.0 is a great bang for your buck with the decent build size of 6 x 6 x 6 inches and SD card compatibility. I printed out numerous projects so far and the print quality on this machine is fantastic. The only issues with printing is that it sometimes has trouble printing small details. However, this could be improved by changing the print settings in the XYZware, like making the extruder move at a slower rate, which decreases streaking. So, one of the most important features about this printer is its usability. Let me tell you right now, this machine will take you a while to set up properly. There isn't the three-knob calibration print bed that other 3D printers have,for this printer wants to be more approachable by maintaining a fixed, leveled print bed. The only thing you have to do is fix the Z Offset, which is the distance from the extruder nozzle to the print bed. This is the only calibration you have to do but it can be tricky getting it right the first few times. Unfortunately, not all of these printers were made the same, one printer could be printing excellent at .90mm offset, but mine functions the best around 1.65mm offset. This printer does 100 to 400 microns, and the infill and speed are all adjustable in the XYZware. I've printed out some quick decorations for my desk, but I've also spent a few hours printing out this model of the Statue of Liberty at excellent quality (100 microns) and slow speed at a 30% infill. The quality of the model was amazing. Overall, the 3D printer was hard, even frustrating at times to set up properly, but once it gets going it produces some of the best prints I've ever seen.

My first 3D printer and I love it. The instructions are clear and it is easy to assemble out of the box. There are a ton of youtube videos on this printer so this has helped me a lot. What I found most valuable is to make sure you FIRST mechanically flatten the bed and then do the auto-leveling. I do an auto-leveling before each print because every time I remove a previous print I fear it moves the adjustment. Remember we are printing ~0.12-0.2mm layer heights so I think it is important to auto-level each time. It only takes a minute or two. Also do it with the bed and nozzle at the temperature you are going to print at.

Very easy setup. Took 10-15 minutes. The magnetic bed it has is awesome. Just flick the print once its cool and comes right off. Print quality is nice and faster than what i had. Mine came with the camera , which is less trips to the workshop. Creality cloud is nice can slice and upload remotely and even start a print from my phone. Lastly the auto off function is nice for those prints that finish overnight or while i am away. Love it worth every cent

you'll pay a premium for this filter, but the 32 layer multi coating and hardened glass make this a good long term investment.

I normally don't use filters. Why put an extra layer of glass over my expensive lenses. But the Grand Canyon is an extreme environment that is tough on cameras and lenses. I put these new UV to the test with the silt, sand, and water in the canyon. The optical quality is superb. And I'd much rather keep cleaning my filters over and over than the front element of my lens. They have earned a place in my filter kit. Thanks B&H! Do great work, @RalphLeeHopkins

These filters seem well made with Schott glass and 12 layer coatings. The UV filter is clear and distortion free. The CPL filter rotates smoothly and is packaged in a nice padded case.

I mainly use this filter as a protective layer for my lens, but I decided to get something different from the standard UV glass filter. Seems to work well, although with post processing using software, most filter effects are no longer needed.
