Phrozen Sonic Mini 4k

[timwatson]

No update, but have been using the printer all night. Even though I made the clip to use as a drip hanger for when prints are done. There is barely enough room to even tip the print head up on end without me smacking into the upper part of the machine. And man the whole thing out in the open design sure is messy. It feels like so many steps backwards.

They need to make an OG Photon with a stronger UV light along with a 15 micron pixel screen 

You can extend the height and since you have a longer lead screw you should. It helps a ton. I will get you the file to change and run in the morning.

If they won't cover that then what exactly will they cover?  You just bought the thing.

I know it’s the worst customer service.

Wow!  They are saying that dead pixels are caused by hardened resin pressing against glass screen?  That sounds like bull to me.  I also have a feeling that that English is not their first language.

[Chris333]

I have scraped hardened resin off my Photon screen several times with a razor blade, no dead pixels in over 2 years.

This screen is $90 bucks.

Guess if anything this thread will let anyone else know not to buy one of these.

For sure!  What a poorly executed machine.  Very flimsily built.

Is the screen even available yet?  The last I looked it was out of stock, or just not available.

I've said it before and it's worth repeating...  I should have just bought the Elegoo Saturn instead (the caveat here is that the Saturn's are very hard to come by!)

Wishing now I had bought the Saturn. That's what I looked at first.

@Chris333 to change the height of your machine in "firmware".

M8026 I145;

You make a new text file and call it "new_height.gcode" Then inside that file place the bit of code mentioned above. Where the number after the I is 145mm. Yours is probably like 160 if you're using the photon lead screw. Then you put that on your USB card and "print" the new_height file.

It makes working with the build plate tolerable then. Mine is set like this and I used this code to set it. Let me know if you run into troubles.

Me too...  I tried getting one on the pre-reservation release but waffled on hitting the "buy" button by about 20sec. and lost out.

Now they're hard to come by, I guess the mfg is having a tough time making them fast enough!

But then I'd need a longer rail or it would "go off the rails"

Oh dang I forgot you have the old rail. I think you have about 10mm to work with. You might check.

[timwatson]

@Chris333 do you have a picture of how your machine turned out? I think I’m going to get the sheet of aluminum and try that.

[Chris333]

Here it is right now from the top:


You can see 3 more screws under my tape. I used 6-32 screws and countersunk the hole with a bit in a hand drill.

[timwatson]

Looks good how is it printing after the stiffener?

[Chris333]

Less flexing, but not all gone. You can see the angled pencil mark where I plan to add a rail brace like Jeff's.  With your dual rail it may be stiff enough as is.
