Looking good to me. It looks like the outside most perimeter on the first layer isn’t adhering well, but otherwise, it’s good.
I noticed on your lcd print that the bottom had the elephant foot. That’s caused by being too close. You might be a bit too far away, or you might need a hotter bed (I print at about 50-55C eith PEI/PLA). You can also slow down the first outside perimeter so it’s not tugging so much.
At any rate, go nuts printing.
In Cali it feels like when it went legal you could spot the new stoners. I swear there were/are tons of cars that are driving 10mph UNDER the speed limit now.
In the bay it is ridiculous, you can smell it as you drive passing cars, in peoples pockets as your shop…anywhere in Oakland. It isn’t my thing and I don’t mind it at all, but I wish some of them would realize how it seems to an outsider. Booze is legal, Imagine grocery shopping and having people smell like gin, or smell gin as you drive. If someone always smells like booze they have a problem, if they need to take a shot when they wake up or before a meeting they have a problem, have a flask in there pockets grocery shopping, problem. Weed is the same.
Sorry that was mighty rant-ish.
Just to add to this off topic. Here in Colorado. A neighbor has a day care business and anytime after 5 (and sometimes before) you can smell it (not just a little) from our yard from their house. I don’t know what to think, because I don’t think they are abusing pot, and I respect them running a day care from their house. It just feels wrong to do them both in the same house.
I’m in the “been there, done that” camp - just not my thing. However that’s the ONE thing here that I think the legislators missed the mark on. They aligned it with our tobacco smoking laws (in terms of where you can and can’t - with a minor exception being while driving). To me I feel that they should have aligned it more with the alcohol laws - or relaxed the alcohol laws. I figure if buddy is allowed to smoke a gagger in the park I should be able to enjoy a nice cold beer. But I’m not allowed.

Here’s Calicat #2. Seems much rougher than #1. PLA printed at 205 (first layer) 203 the rest. Bed temp 60 deg. I’ve got another print running right now and it seems that I will go back to the “single piece of paper” z height once it’s done. And I’ll try slowing down the first layer.

What are your print speeds? Just to start try 30mm/s print, 50mm/s travel, print fan 90% starting on layer 2. keep teh first layer at 50% speed.
Maybe give us a screenshot of your speeds page. I might have to go in and update all the print settings…I haven’t touched them in years.
I have looked for the fan settings a few times and I know I’ve seen it but I can’t for the life of me find it. (It’s probably going to slap me in the face as soon as I post these screenshots…)[attachment file=73893]

Is the filament loose? The banding looks like what I had when the extruder was tugging on the filament to get more. It would lift up or sink down based on the tension in the line.
The fan stuff is in the filament tab, right?
Right you are. Found it. And I see settings that explain to me why during this print everytime I manually turn the fan on using the LCD it turns itself off…I think these layers are quite lengthy prints (steampunk goggles eyepieces…you know…halloween is coming ; )
I better move this thing down to my office or I won’t get anything accomplished! I need a filament spool holder. Never did follow up on my threat to whip one up on the MPCNC. That’ll get me at least to my desk. Maybe a client can catch my attention while I’m there.
I’m willing to bet the filament might have been a little snug here and there through that print (see previous post about needing a holder). Not sure if I messed with the top screw on the extruder while monkeying with the bottom one that kept falling out (I’ve just left it out for now) either. I assume that one adjusts the tension?
Top one.
Those are two topics. The boot on the extruder tensions the filament in the extruder so the great grand and doesn’t skip. Three problem I had was that the extruder would pull on the filamemt, which would lift the extruder a little, until the spool gave way and spun out a few inches of slack. I haven’t seen amyone else complain about it though. If it’s in your office, you can just print the calicat again and just make sure there’s plenty of slack. If it looks better then that’s your problem.
I just aborted the goggle print. It was pretty confusing with all the supports - not one to be learning from. And it had some big missed layers. I’ve lowered the Z to a single sheet of paper, cleaned everything up, loosened off a pile of filament and am printing Calicat#3. Using the same gcode file from previous 2 so the speeds are all the same. Immediately I’m seeing way better adhesion even on the skirt.
Back in an hour…
Here’s #3. From left to right, 1, 2, 3. Better but oddly #1 has more consistent X planes. Or I guess that’s Y planes -made by the X axis…
I’ll look at the speeds and try a new file. How much issue is touching the filament? Do the oils etc from my hands cause troubles?

Any chance the wheels that move your belts aren’t solidly tightened to the stepper shafts? You seem to be walking around a bit on both X and Y.
Yeah, I am seeing some funny things. Lil z wobble and maybe belts or bearings.
Just in case lets try this file.

Printing now (halfway through). Made me think of a fun 3d printer game like the blind bags my kids love so much. Send files - no peeking, just print and enjoy the surprise. I imagine there would have to be constraints like no 23 day print files and nothing too explicit or obscene. Good fun though…
I’ll check the gears when the print is done. is there a specific belt tightness I should be aiming for as well? Could snug those up a notch maybe.
Hmmm. I like that idea, but I’m not sure I could print just any gcode. It’s worth a try though.
Here’s the result. A few misses but not a load of wiggling to my untrained eye.

Dang that is not good enough. We can get it wayyyy better.
Is your print fan pointed just below the heater block or pointed right at it? Did it come on and is it blowing the right direction?
What filament are you using? Did you get a spool holder rigged up?
