Harbor Freight black widow/spectrum problem

I’m at my wits end trying to figure this out and it didn’t take me long to get there. As the title says I’m using a Harbor Freight black widow airbrush. I only use acrylic. I’ve been using a cheap avanti compressor. Up front, I haven’t always been diligent on cleaning it. Anyway, over time it’s been performing worse and worse..harder to get good flow, spattering of paint etc. Now when I put the nozzle and nozzle cap on it hardly blows any air much less paint. Take those off and it works fine. The nozzle, needle, and cap are all .5. I’m wondering if the issue could be those 3 holes and if there could be dried paint in there. Using my ear hole camera I can’t see any way to clean those from the back side.

So far, I’ve tried soaking it in alcohol, acetone, and boiling it in water. I’ve taken the little o-ring on the inside out when doing this. Any suggestions are appreciated.

Bargain bin Q2

My eBay return Q2 has been doing great so far. I’ve printed with PLA, PETG, and ABS so far. One minor hiccup which I think is easily explained.

While printing with PETG I got a no trigger on probe error message twice. According to ChatGPT this can be caused by filament being stuck to the nozzle which prevents a complete or accurate bed probe. I’ve only gotten this message when using PETG so I tend to agree.

This is my 4th Qidi machine and by far I’ve enjoyed it the most. Reviews said the fan is loud but coming from an FLsun S1, and owning an FLsun T1 Pro, the noise-which I don’t think is loud-isn’t an issue. Print quality is on par with every Bambu machine I’ve owned. If given a choice between this or a P2S I’d have to say the clear choice is the Q2. Chamber heater+370 degree hotend gives the Q2 a very distinct edge, not to mention how beautifully it handles PLA and PETG.

Whoever returned this, thanks! Closing in on 100 hours and so far, so good.

This is probably going to seem redundant or downright unnecessary to some, but after scrolling through Marketplace and seeing some of the idiotic prices there it may be necessary.

If Bambu is selling a brand new (hence unused and pristine) P2S Combo for $799, your worn out P1S with the OG AMS is not worth $800. If Bambu is selling a brand new (also unused and pristine) X2C Combo that comes with more features and newer, better technology than your equally worn out X1C for $899, then your worn out X1C is not worth $800, $900, or $1000.

While true that in a free market economy (aka capitalistic) the price is whatever the market will bear, common sense dictates that selling it-even at a loss-is more desirable than not selling it at all assuming you’re using the money derived from said sale to fund the purchase of a brand new, better printer.

This theory also applies to those selling an A1 or A1 Mini Combo for $400+.

One of my young adult children has stage iv brain and spinal cancer. Having been diagnosed a couple of years ago he is nearing the end of his fight. Over the past couple of weeks he has deteriorated rapidly and I’ll be surprised if he has another week left in him. God was gracious though as in that two year span he gave his life to Christ. He has faced this in a fearless manner and has told me he’s just ready to go home.

His mother and I differ greatly on theological matters. She believes it’s always God’s will to heal etc. and we do not get along very well (we’ve been divorced 20 years). My son (the one with cancer) is at her house now under hospice care. My oldest son was also there yesterday and messaged me to say that their mother was asking when I’d be there and for me to hurry up because my son was probably waiting on me to get there so he could “let go”.

When I get there she tells me I need to tell him it’s ok for him to let go and go get some rest. Her belief is that he’s holding on because he’s afraid to leave knowing the pain those he leaves behind will feel. My belief is that God is sovereign and it is He who numbers our days and that no one will spend one second longer here than what He’s ordained for our lives. Others chimed in of course with stories about this or that loved one who didn’t die until a specific loved one told them it was ok to go.

I cannot buy into this nonsense, especially when the Bible clearly says God has numbered our days. To me, it’s along the lines of people who see a cardinal outside their window and think it’s a dearly departed family member dropping in to check on them. God isn’t on His throne checking His watch anxiously waiting for Uncle Bill to show up and give my son his permission to die. I’m not wanting to be insensitive to what she’s going through, but I am filled with joy at knowing soon my son is going to be looking into the face of his Savior Jesus Christ and don’t have the time or energy to participate in silly superstitions or outright lies people tell each other for a little comfort.

My son has a big heart and we’ve had some very deep conversations over the past two years. He’s told me numerous times to not be sad for him when he goes, but to be glad. I know that when he’s gone he will be more alive than anyone he’s left behind. Knowing that I’ll see him again gives me comfort I cannot describe. I do not want this issue to spiral into an argument with her and I’ve ignored her so far. She’s the type that simply doesn’t quit though and will continue pushing if for no other reason than to provoke an argument with me. I’m open to suggestions on how to deal with this.
