Thanks, @dsage. I think that was the software I was running before all this started. My printer (I bought it in early January of this year) also came with relatively old SW and I updated it once before I even started trying to print anything. It might be grasping at straws to think the...

My printer's bed is glass. It's over something else, but the surface I work on is glass. More about today. When I first tried to print the same file as yesterday, the print was almost invisible. Very thin. I aborted the print and redid the bed leveling with my .0040" A&W root beer can...

Turning off all fans and A/C not only didn't work, it was worse than yesterday. The print level adjustments were all way off. Filament stuck to the bed a little but not everywhere and the extruder swept up filaments as it went by.

Thanks. I'm about to do my experiment of not letting any fans or the air conditioner in the shop run. Those sound like something to keep in mind.

Do you what the mechanism it fixed was? I mean, are they taking out backlash while adjusting the knobs or what? It seems hard to imagine the plastic would weigh so much that it compressed the springs.

Not perfect but still much better than a couple of days ago. I have the Z offset set to .07mm, which means I used my .004 feeler ga. and put the nozzle .001 lower. This whole issue with not getting good adhesion is new. It's in a room with an air conditioner and isn't really far away...

I had an adventure trying to get Popsicle sticks last week without ordering them from Amazon or Walmart and wasting a couple of days waiting for them. Instead, I decided to use my 3D printer and wasted the entire week. Starting from the beginning, I needed a G-code file and to get that, I...

I recleaned the extruder nozzle and ran the bed level squares test that CHEP has on his YouTube channel. It came out far better than yesterday but still not as good as last February when I did the initial setup. You can see the places, mostly the upper left corner of the squares, where they...

I set the bed level to .004" (0.102mm) using a strip cut from a soda can and changed the Z offset in the printer software to match. Immediately, it worked better. I have some old files on my SD card that I've printed before, so I know they work. I set up to print a pair of threaded standoffs...

I've been using those Elmer's purple glue sticks that somebody recommended. "Washable School Glue" that they call disappearing purple. They stick fantastically. Things with a lot of surface area on the bottom stick so well they can be a real pain to get off the bed. But, like I say, this...

I'll second that. My plate's kinda full now, but always thinking about what's next.

I haven't tested it. I've been working on the camshaft on the lathe, and some other stuff. I copied off your recommendations to look at next time I have that computer on.

Mind blown. That might just be it, Pat. This all started when I re-leveled the bed. To do that, I used a new method that uses a .008 feeler gauge to set the gap between the nozzle and the bed. The YouTube channel I got it from (CHEP here) had the tutorial and I dutifully followed his...

I have a Creality Ender 3V2 that I've been learning the ins and outs of printing on, and in the last few days, it has developed a problem I've never seen before. No filament sticks to the bed. In the last few days, I went to make a little tool to hold sand paper onto a crankshaft I'm...

With 40 plus years in industrial electronics manufacturing, we called anything finer than about 30 ga. "frog hair".

There are simple engines you can build with just a lathe and a drill press. That probably means with a hand drill if you're good. The first engine I made was a wobbler steam engine from Little Machine Shop, which can be done with just those two. I used a milling machine, since I have one...

Are those like pliers? Like Vise Grips? I have some long nose Vise Grips pliers, as well as a bigger, shorter jaw version of them.

Time for an update on the real meat of this thread, although both concrete and using horse urine to color copper roofs were both interesting sidelines I had the stitches taken out Friday (October 1) and have been working toward setting up to resume work on the crankshaft since last weekend...

I've ignored those warnings in the past and never had an issue with it, but I'm being a bit more cautious when I keep reading about big name companies being compromised all the time. If everyone else is going there and it's not an issue, it's probably OK. The fact that you're seeing the same...

Very nice looking drawings. Are you building any one of them?
