  • You only need an account if you want access their cloud storage and sharing management. You can get a tiny free account if you want. I signed up for the freebie since I sometimes work between 2 computers on the same project. But if you only use one computer, it’s not going to get you anything extra.

    You can add Ondsel Lens to your regular install simply by installing it through the add-on manager if you want.




  • Most pets don’t work because their owners don’t bother to train them to do any work. And interestingly enough, I have indeed seen a Chihuahua herd cattle. There was No Fear. It was amazing to see that little toothed monster chase a 2000lbs bull around a pen and into another and then into a barn on command from the farmer that owned him. And a Mastiff will gladly hunt fox, cougars, wolves, and even people if you want them to. They will also happily Netflix, popcorn, and chill on the couch with you after chewing up that human also.

    Why don’t my dogs talk? Well, they just don’t have the physical voice box to form the sounds of human speech, (as you well know). But that doesn’t mean they don’t communicate with people. Actions, like tail wagging, barking in various tones and volumes, rolling on the ground all communicate emotions and situational reports. And us humans understand them just fine. My little Russian Spaniel does her best to “talk” to me with a near continuous stream of moans and groans, and erffs when she sits with me in my recliner. It’s almost annoying when she doesn’t shut up. And they understand my communications. My dogs understand verbal, whistle, and silent hand signals and respond correctly and instantly to them when I’m afield with them. Parrots, have a natural physical ability to mimic other sounds, (as do a lot of other birds). So they are doing what comes naturally to them - a human is not required.

    There are lots of dogs out there that do jobs they were never bred for. Seeing eye dogs, dogs trained for deaf people or assistants to people confined to a wheel chair. Turns out Labrador Retrievers are really great at this kind of work. And I have trained retired Springer Spaniel hunting dogs to work in a hospital as therapy dogs. But that’s not why or what those breeds exists for. Ever see a trained animal act at a circus? They are often what most people would call “mutts”. Mixed breed dogs doing amusing things like ride bicycles and drive little cars around and jumping through burning hoops of fire. And you can often see little Chihuahuas preforming in those acts. All doing things none of them were bred for.

    I like the cats that we have. One, a grey and white is an excellent mouser. But he comes from a very long line of barn cats and has a wild streak in him. The other two, are far more interested in cat toys and sleeping in laps and beds than in any mouse - and that’s fine. A warm kitty in the lap purring away is a calming and enjoyable thing to have on a cold winter’s day. But I’m under no illusion that cats or most other pets can be trained to do all the things my dogs can do.

    Dogs are humans oldest and closest companions and co-workers for a reason.



  • I’ve never had and issue with the linear rails rusting in all the years I’ve been 3D printing. But I do live in a drier temperate climate also. But dust will eat the seals up very quickly as well. If rust is a worrisome issue, hard chromed linear rods are also easily available to prevent any worry about rust. And they would outlast the the non-chrome rails significantly. That’s what I use.

    As always YMMV


  • It’s not so much about lubrication as it is about trying to prevent seal wear. When the wiper seal gets worn and can no longer keep the dust and grit out, the rolling elements have little time left.

    If the bearing as lubricated correctly at installation time, it should never need re-lubrication. But it’s important to keep the rail surfaces clean. And it’s amazing just how dusty those rails can get and just how abrasive that dust is on the bearings.

    I don’t lube the rails, it attracts too much dust. But I do wiper the rails periodically. I replaced the linear rod bearings and rods on my old and trusty Mk3s+ after almost 3500 hours of operation this last winter. Though I should have probably done it a bit sooner.


  • For PLA and PETG, I like MatterHacker, though I have been buying some Voxel PLA lately and that’s been pretty good stuff too. Voxel does run sales that get the price down to $15/$16US a kilo.

    For ABS/ASA, I’m still using a the same kilo of Zyltech ABS I bought 5 or 6 years ago. And I still haven’t used 200g yet. I did dig it out this weekend to print a couple dozen custom cable clips for my boat with it though.


  • I don’t own one - yet. But I have spent a good amount of time reading about users experiences with the brand. They seem to be pretty decent. The company offers good support and works to solve product issues. And users seem to be genuinely positive in their overall comments.

    Just from my own research, they seem to be kind of a hidden gem that no one notices. I think it wouldn’t be wasted time for you to take a closer look them. I just need to talk myself into believing the carbon fiber rods on the X-Smart3 are fine. As always: YMMV




  • The issue is Crealty makes price point products. Maybe you get a good one or an OK one, a kind of bad one, or a dumpster fire. And there is no way to know what you are going to get, to get the results any one user is expecting - even if you consult Tarot Cards…And add in the total lack of support it can be more than a little bit of a gamble to buy.

    My personal opinion is, if money is that tight that’s the best you can afford, then you can’t really afford cheap - let alone the ongoing costs of 3D printing, (upgrades, repairs, and filament ain’t free). And since it’s very often new users looking to get into the hobby, (which is great), they have no idea just what the learning curve is like when things go wrong. And how fussy it can be to make those failures go away. That shiny new cheap printer that provided that quick dopamine hit when you first unboxed it, can quickly become a point of never ending frustration and a bit of a money sink for a new user.

    Overall, buy what you like. I’m certainly not paying for it. But not a lot of people have ever regretted the “Buy once, cry one” approach.



  • As someone who has tried and used all of the popular commercial and free CAD software - Use what you like and works best for you.

    I used OnShape to teach some rudimentary CAD skills to High school students just because it will run on the low powered school issued Chromebooks without problems and it fit the school budget - free. It was easy for me to pickup because I spent years using SolidWorks for a living as a toolmaker.

    The most difficult part was getting the kids to use a mouse. Noticeable number are so used to touch pads and screens that they didn’t even understand HOW to the the mouse.
