Help with Creality Harlot one printer

[V8tiger]

I just got a Harlot One printer....I've tried printing a few of their stock files that came with the printer. I leveled everything. Had one print come out fine then the next two were not so good only printed a little bit of what it was supposed to be. I'm thinking it has to do with the settings, which from what I'm learning are limited on this machine. Does anyone have any suggestions. I'm using Yachee. Thanks for any help at all. thank you.

I had an issue like this with my new printer - I had plenty of supports but incomplete prints.

When you say "Yachee", do you mean "Lychee"?  The slicer app?

If so, the solution to my issue was gradually increasing the light-on time in the resin settings in Lychee - I think the issue was that the resin wasn't curing properly on my new machine (although the identical settings had worked great on the machine before).

So, my light-on time was I think 1 second, and I ended up at 4 before I started getting normal prints...not sure if that will fix YOUR issue but it helped with mine...

Did you have supports hanging from the plate, but nothing else? Could be exposure too low or weak supports. I would go with low exposure first as you say you are using files that came with the printer. What are your settings and what resin are you using? Also, how experienced are you with resin printers? Have you used a calibration file to determine your best exposure setting? I like this one: https://cults3d.com/en/3d-model/various/exposure-tester-v2  Here is a video that explains how to read the exposure test print: https://youtu.be/NrNfqOCilAQ?si=urx5HcHxtpVaKvwY  The explanation starts around the 4 minute mark.

I have a Halot One and most all of my problems were from lack of experience and knowledge. I think it is a good entry level, learn the basics printer. 

What is the temperature in the area that you are printing? Resin prefers warmth. Below 68F and you can start running into problems. Some resins require quite a bit higher temperature.

Make sure the resin is mixed well. When you think you have shaken the bottle enough, shake it some more.

One thing you have to make sure of when leveling the build plate is that it is actually level. The way that the build plate bolts on causes it to pull up slightly on one side as your are tightening everything. Make sure your paper is snug at each end of the plate when you pull it out. Loosen up and try again if it doesn't seem to have even snugness. 

Make sure your FEP isn't loose.

Make sure you removed the protective film from both sides of the FEP.

Try these settings to start:

1. Initial Exposure - 45 secs
2. Exposure Time - 3.2 secs
3. Motor Speed - 1 mm/s
4. Rising Height - 7 
5. Bottom Exposure - 5 layers
6. Turn Off Delay - the stock setting, I don't remember what it is.

These settings are meant to see if it will print the files that came with the printer. You might even want to raise both exposure times a little bit to start.

The only thing I don't like about my Halot One is that it is small. That's why I have a bigger printer sitting next to it.

There is a Facebook group dedicated to the Halot range of printers. Very knowledgeable people there.

Yeah I meant Lychee! Duh....(smiling here) So I'll try increasing the light on time.... thanks a lot!

Thanks! I'm gonna make sure I check all the things you mention.... and thanks for the reply!

I will try to help with anything Halot One specific. There are others on here with more resin printing knowledge and experience. Hopefully one of them can help if I can't.

A few of my prints are not sticking to the bed. How raise the exposure and make the bed a little thicker...? can't seem to figure it out...

I'm just going to throw some ideas out there for you to try. Unfortunately, it is hard to troubleshoot without being able to see what is happening.

Make sure when you slice the file that it is actually on the build plate. I had that happen once when using the Halot Box slicer. It had a bug that raised the file from the plate when you sliced it and I didn't notice it.

Does it look like something was on the plate at some point? If so you can probably rule out the above. 

When you have a failure, is it on the same part of the plate? I would lean towards a plate that needs to be leveled if that is the case. Do you have even tension on the paper that you use when leveling? If one side is tighter than the other, level it again. There will be even tension at both ends when the plate is level.

I have heard of people needing to hit the plate with sandpaper to gain adhesion. Here is a link to a video tutorial on the Phrozen website: https://phrozen3d.com/blogs/tutorials/sonic-mini-4k-sanding-the-build-plate 

Is your FEP tight enough? A loosely tensioned FEP can cause failures. 

What resin are you using? Some are harder to work with than others.

You may need to bump up your initial exposure. I have used as much as 60 seconds. 

Have you made sure that the protective film has been removed from the screen and the FEP? The film that is over the screen is only there to protect the screen during shipping not for resin spills. There is protective film available for that purpose.

 

Try this:

1. Clean the build plate as best as you can.
2. Level the plate as best you can.
3. Use fresh resin that has been warmed up and shaken thoroughly.
4. Find a file for a small object that you have had good luck printing. 
5. Add that object to your plate 6 times using your preferred slicer.
6. Arrange the objects so that there is one in each corner (a total of 4), and 2 in the middle of the plate (1 at the top and 1 at the bottom). Sort of like this ->  :   :   :
7. Print this using your settings that have had successful prints.  

My thought process for the above is that if you have failures on one part of the plate then the plate might not be level. The failure occurring where the plate is farther from the screen relative to the successful prints.

Facebook has an excellent group that can help. Many knowledgeable people there. They will be able to help way more than I can. https://www.facebook.com/groups/crealityhalot  It's a private group but I am sure they will accept you. 

I'm hoping someone else can chime in a give you a hand. I'm sure I am forgetting a lot of things that could be helpful.
