1:5 VS 1:7 Twist for Subs Only Gun

This lil PSA .300 B/O is about to get some upgrades. I have a Dead Air Nomad L and Q Trash Panda on the way. I'm not sure what one will live on this gun but either way I'm going to need a new barrel / handguard or both. (Don't judge my suppressor choices. I had to take what's in stock considering what's going on and having a local FFL that will do a Form 4473 for them.)

I reload so I don't mind having this be a sun-sonic only gun. Is a 1:5 twist the way to go? I'm just getting worried about baffle strikes. With a 1:5 twist is shooting a 125gr supersonic an absolute no-no or is google making me trip out for nothing? I have tons of Speer TnT 125gr supers loaded up because pre suppressor that's what this gun lives on. Again, I'm cool with not shooting those after the suppressor I just want to know.

I have a bunch of Berry's 220gr to load up when I get my suppressors. Berry's says max FPS with 1:5 is 1000 fps while 1:7 is 1300 fps. This kind of worries me too...

I'm the type of person who will research a toothbrush for 2 hours. Talk sense into me please.

Am I Legit just screwed out of $1600?

My little brother is graduating from the Naval academy and I booked tickets for me and the family to go see the ceremony. The military had other plans and pushed the date back with 5 days of notice. According to google I should have the ability to reschedule or get AA credit with a $99 cancelation fee but according to AA I'm just screwed out of 4 airline tickets.

For further context, I purchased the tickets through Capital One because I had $600 in points. I called their customer service yesterday and they made it seem like it was no big deal and they would give me a full refund in the form on Capital One points on my CC. It seemed too easy so I called again today to verify and of course they couldn't find anything in their system and said no refund was in place. I purposely withheld the case number for about an hour. When they gave up I finally gave them the case number I was provided. They then informed me that the refund request was simply escalated and they would have an answer in about 10 days. That does me no good since the flight in in 3 and I don't have any hopes for a refund because they said multiple times that these tickets are non refundable.

At this point my only hope is AA customer service. I called them and the wait time is 2 hours... I opted for the call back. I have 0 hope that they will do anything since I purchased the tickets through Cap One Travel.

The worst part is I now have to purchase tickets again for the newly rescheduled Navy graduation. I would like to see my little brother before he gets shipped off. I'm going to be financially drained after this but I guess there's not a price you can put on seeing a brother considering anything could happen overseas.

Is there anything else I can try?

Anyone have their hotend fan crap out?

Is there a way to test if the issue is the fan vs circuit board?

I started printing PLA after not printing any PLA for a long time. I have one toolhead that cannot get past 1st layer without getting a heat soak clog. I've been printing ASA for a while so I didn't notice before but it might explain the never ending first layer inconsistencies I've has with ASA.

Please let me independently change my brim filament

Is there a logical reason why I can't do this? Currently the only way to change brim filament is to edit plate settings and change the filament print order. I need to print the white first but brim clean up would be so much better if I could still have the brim be black. No to mention that the brim would probably function better if it printed with the border instead of cooling before bonding.

1 year and I'm still constantly amazed

One year into 3D printing and I'm still amazed every time. This is my first time printing at a 45 degree angle and the first time I have used PETG as an interface with ASA.

The entire back side of this part was supported with PETG as the interface and the finish is better than most top layers. I'm absolutely astonished at the finish on this part.

For those wondering this part was screwed onto my RV door. There's a lever that flips into the open slot to hold the door open. The orignal had ripped out. I oversized the new one to cover existing holes and give it more leverage.

My only regret is that I used a throw away ASA color assuming this print would take multiple attempts.

How do I get my z-offset to stay?

Anyone else have this issue? I'm going crazy trying to have this machine keep my Z-offset setting. The z-offset adjustment is also very confusing because there's areas of adjustmentand they contradict each other. Hopefully someone can make it make sense for me.

In print config I belive it shows z-offset= -0.05 one E0. It is my understanding that you only change E0 and it changes the other 3 extruders.

When in the GUI of the my U1 it shows a z-offset value of 0.024 while printing. I can't figure out how that coralates to he config file setting. If i adjust it mid print to 0.000 it's perfect.

So basically in snorca I set my z-offset to -0.024 and it prints perfect. However, if I click reprint from the display it completely ignores it. Further more, if I run the heated bed leveling it also ignores it.

So my option is to change it in the printer config file. But when the U1 gets an update it seems to revert back also. Plus I seem to need a different z-offset for asa vs PETG so that's annoying.

It's very frustrating because I know exactly what I need my z-offset to be for this particular 13HR print and I need 100 of these prints. I just want the machine to keep the setting I tell it to and not auto calibrate it out.

Tips for a first time builder

I'm hooked on 3d printing...I bought a Flashforge AD5M first to test the waters. I also own a Snapmaker U1 now and I'm starting to look into building my first voron.

Before I dive down this rabbit hole I figured I would post here and ask for any tips. Basically, if you had to build your voron all over again what would you do differently.

I'm just now starting my research and getting all my ducks in a row. For background, I've been into micro electronics including soldering and have built quite a few open-source projects that have taken multiple weeks. I'm confident in my skill and determination. Coding and gcode would be the only skills im lacking.

For wants I would love to have multiple toolheads if thats possible. Also bigger is better in my eyes. I'm always running out of build plate.

Thanks and I'm looking forward to becoming a part of this community.

Default z-offset in printer.cfg

Would anyone with a bone stock printer.cfg file please tell me what the default z-offset is set to on all extruders?

I changed mine a long time ago and cannot find in the wiki what the default settings were. I just realized you can change this in Snorca now.

Also my printer.cnf is showing...

E0 Z-offset -.05

e1 Z-offset 0

E2 Z-offset 0

E3 Z-offset 0

I know I set the all the same so I'm not sure why it changed itself but I do notice in my current multicolor prints that E0 is the color I'm having an issue with and the other extruders are printing perfectly.

Thanks for your help

Changing brim filament

I'm usually not this slow in the head but I've gone through every snorca setting and I'm clearly missing somthing.

​

How do I select what filament my brim is printed out of? All of the Google answers say there's a drop down in other>brim but I do not have a drop down. Advanced mode is enabled.

How to Sweep/ Loft to Reduce Material and Prevent Warping

I'm trying to basically chamfer from the blue rectangle to the 6MM high border around this object.

I'm playing around with the sweep and loft tool but can't quite figure out how to make it go in multiple directions. There's gotta be a way right?

Can't use Snorca after 2.3.3 update

Home and device page are just white. Seems like a cloud/network issue but when I do the snorca ping test its fine and I can ping my U1 from this laptop.

Anyone run into this or have some simple things I can try.

I'm scared of uninstalling because I don't want to loose all my custom profiles.

EDIT: I ment to attach screenshots but it wont let me attach them in an edit.

Self Employed 401k options?

I've been self employed for 6-8 years now. Last year I converted from a single member LLC to an S corp. I'm late to investing in my retirement and opened a Roth IRA last year. I put the max contribution of $7,000 last year and planned on doing the same this year. I still feel like I'm behind and was looking at other option to catch up. My friend mentioned that I should be able to get a 401k set up now that I'm an S corp with payroll. I don't have employees, it's just me on the payroll.

If that's true I think I might have a great opportunity to really accelerate my retirement investment.

Question 1: I run a S corp with payroll set up. Can I set up a 401k and would that be better than my Roth IRA?

Question 2: Can my own company match contributions and whats the limit? Also does the company get to write off the matching contributions?

Question 3: How do you get over the emotions of dumping your money into the stock market? I hate the stock market because it's rigged as hell and it feels like there's a bubble that needs to pop at some point. I have shit luck and the seccond I have substantial money in the stock market will be the exact moment another 2008 happens. I feel way better about land, realistate, and other physical assets. However, I've been saying this for 6 years...

Finally happened to me

Thankfully, I've seen other post here with people putting tape on the prime tower to try and save their print. Pray for me U1 people.

I'll be looking into alternatives to having PETG and PLA in the same prime tower moving forward.

If anyone is interested, it actually happened after removing the enclosure lid due to toolhead 3 having a docking error that I had to manually fix. Also a first, I'll run the toolhead calibration after this print.

Primer sealant?

I use federal HST for my EDC. I have a good collection of nickel plated brass and one day I want to make some fancy no expense spared carry ammo.

What is the blue sealant they put around the primer? Also can you put it around the rim of the jacket to really seal everything up?

I'm sure somone here has already done this. What worked best and what supplies do I need to buy?

u/Accomplished-Bowl551 — 3 months ago

Can somone who has PETG dialed in on their U1 post filament settings for me please?

Basically I've calibrated my settings for PETG multiple times. I have specifically done flow rate and PA over 6 times each and I always get the same results. However, my real world prints are very over extruded. At this point I'm skipping the calibration tools and in Orca I've made a primitive disk a few MM tall with "A U" text cut into it. I'm getting better results at about .90 Flow Rate. It just seems really low.

I would love to compare my settings to somone else and see if there's anything that really stands out about my settings.

Thanks!
