Max 4 Bed adhesion with PLA is way too strong

To all,

Per previous, Max 4 finally up and running. As I've done with my other printers (not many, just two Elegoos, a 1 and a 2), I printed a benchy and then a poop chute and a polar cooler stand/drainage bin. Note: While others have said they see no water from the Polar Cooler drip tube, where I am has my house at 38% relative humidity and I am getting a slow (very slow), drip from the tube that could cause damage on a hardwood floor or soak a small area of carpet for a long print (the poop chute and polar cooler stand were each about 16 hour prints). Note: Prior to any printing, I removed the build plate and scrubbed the hades out of it with Dawn, fingernail brush and I used rubber gloves to do all of this to ensure no body oils.

Now, I have yet to do a full calibration (that's the next step), but of all 3 items printed, the PLA has stuck to the build plate (default textured side of the build plate), almost worse than any PETG I've done on the Elegoo's. We're talking 15+ minutes with plastic scrapers, fingernails, alcohol, freezer, and reheating the bed to get it all off.

Per google/AI, the probable cause is the nozzle is too close to the bed and driving the filament into the textured surface, changing the Z-offset and/or using a release agent is recommended. As I noted previously, I can watch the fluid print log and I see the start print probe calibration and it's setting a Z-offset at the end of the process. So, the questions boil down to this:

  1. The device tab shows Z-offset is currently set to zero while the machine is idle. I'm assuming the probe sets it to a per job setting and then it is reset back to zero (as I said, I saw the previous probes say they're setting a Z-offset) when the job is done?
  2. If I set a permanent Z-offset via the machine panel, will it be picked up/override or be additive to a normal probe? Note: The google/AI and the search entries (mostly reddit posts), are adamant about doing it at the machine and not in the slicer.
  3. I want to set at least a minimum Z-offset before I run the normal .2mm film test because I don't even want to think about scraping that much PLA off. What would you use as a starting point?
  4. And finally, when setting the Z-offset, since this is a core X/Y, to move the plate further away from the nozzle all my adjustments should be with the down arrow? Any up arrow movements would make the bed closer to the nozzle which is not what I'd want to do in this situation

Finally, once I get this done, I'll print a couple of stupid things and if they release easier I'll start of the full bed Z-offset calibration with the .2mm film. As I said, scared to death I'd never be able to get all of this off (and yes, I know I can stop it, but I'd still have to let it run long enough to dial in the Z-offset.

Its Alive!!! Qidi Max 4 finally up and running

To all,

Even with Mr Murphy (who's law we can't escape), and Mr Rube Goldberg, I finally have the Max 4 out of the box and up and running. I can't thank you all enough for getting me to this point and helping me make the decision. I've just started the norms of benchy, poop chute, polar cooler stand and others printing and getting used to the machine and the Orca/Klipper UI/features. My deity what a difference in having a full klipper interface. There are settings, readings, status, Etc. that have put me into information overload compared to my Elegoo CC1 and 2. The Orca nightly build still needs some work and I've had a few prints not start with weird errors that just doing a restart fixed, but I'm working through increasing my knowledge. I plan on doing a small series of posts from a neophytes viewpoint such as packaging->unboxing, Assembly, first prints, features, Etc. Nothing long, just a what I'd love to see changed and what I just plain love or don't. Once again, thank you all again for your knowledge, comments and help to a newbie that is grateful as hades to you all.

Bob

PS: It may be the Fluid interface that has all that information. Still learning

To all,

This sub was so kind to give me some advice re: resetting my new puppy's potty training habit, I have one more question to ask. Our house is truly an 'online' house, we have laptops, tablets, chargers, cords almost everywhere. While we have puppy proofed the house as much as possible, there's still the 'have to run to the bathroom asap and set the laptop down and run'. In just 2 minutes (and that includes washing hands of course), I came back to her chewing on a laptop power cord and she'd almost made it to the copper.

We've tried about every bitter apple spray that Amazon sells and she just ignores them and goes after cords and carpet edges. We know it's mostly a teething thing (the vet she sees says she's starting to lose her baby teeth and her adult are pushing in), but I'm so afraid she's going to somehow get a cord and either hurt herself or ruin a piece of equipment (I'm more worried about her hurting herself).

Does anyone have a brand of spray/coating they recommend that she won't ignore (and I know there's no guarantees)? My thanks in advance

To all,

Just hoping for some advice. I have a 4 month old Cavalier that we've had for about a month. Due to a two story back deck where she could not climb the steps when we got her, she was taken out front to potty train. Now that she's older, she's now able to go up and down the stairs with ease and follows her 6 year old brother Cavalier like he's the sun and moon to her.

However, while she will go inside (either inappropriately or on the pee pads she was raised on), or in the front yard (where she was starting her 'outdoors is where you go potty training), she refuses to use the back yard as a potty. As an example, in the morning (~5 hours of sleep for her), she'll whine to go out, we take her out with her brother and she'll follow him down, watch him do his business but won't do a thing. Then when she comes inside within 10 minutes she'll do an inappropriate potty. If we send the male out back, and take her on a leash out front she'll do her business as that's apparently her 'potty' in her mind.

It doesn't matter what we do, if she doesn't go, we'll crate her for 20 minutes and try again and she still won't go. The only place she'll potty is in the front yard or in the house. As I said, she'll sit there right next to her brother and watch him do his business and she does the normal sniff and checkup on his business, but refuses to do one of her own.

I'm thinking of collecting some of her #2s and then seeding the back yard so she smells her own potties but at this point I'm at a loss. I've gone so far as to go down with her (which I do always), and sitting on a chair for an hour+ and she still will just hold it until she gets inside or I bring her in and then straight out the front door.

Anyone have ideas on what to do?
