Bad bearing on a moving part. Or a bur along a rail, It catches just enough to cause the smooth motion to jitter a bit as the head moves along. Blobbing the material down instead of spreading it nice and even.

You have a draft going through your room, I used to have same issue when my printer was beside a window. Less when I moved the printer to middle of the room and issue was gone when put the printer into a closet. With closed doors.

You can try lowering bed temperature to, the warm bed keeps lower layer pliable but the upper layers cool and contract pulling the more flexible layer up and away. So a cooler bed temp should make the bottom layers more ridgid.

Amazing to assume that a franchise out in cottage country makes anywhere near the same revenue as one in down town toronto. What would you say is market wage? $20 per hour $25 per hour $35 per hour?

Lol Canadians don't want those shit jobs to begin with.

You are a fucking monster. The point of this was to have some laughs not cause a poor walmart employee to beat their spouse or off them selves. Damn you're cruel.

Dear-modern will find a way to make this in a 10/10 home

One of the most confusing places to be in is a Canadian machine shop. Half the machines will be imperial and the other will be metric. Work order come in both units on the regular.

You give the word power and meaning by viewing it certain way. To me cuss words have no power they are meaningless. equivalent to a simple filler word. Others around you might give power to cussing, but then why is it your fucking problem that they choose to be simps for a word?

Everyone worried about the bending force, the retaining slots will tear out and drop the damn thing on the desk well before it bends.

Yah this is bad I run a cnc plasma table, big table 10 feet x 20 feet. It uses floppy disks. Pain in the ass to find a new drive and pain in the ass to find new disks because constant write re write emf and metal dust kills them. But despite that it's still cheaper and easier than a $15k retro fit to a more modern controler.

One weird trick that DOT doesn't want you to know.

Now do it like 5 or 6 more times on the rest of the bed and now it's textured for extra adhesion.

Can you post the g code ?

What printer do you use. This is a mechanical issue. It's something binding as the one x or y is traveling could be a bearing or the stepper motor it self. It prevents the arc from being fully formed even though the machine thinks it is key point you made is that randomized z seam leaves the same mess, but if notice it's not all the layers are cut short only some.

Take the belt off and move the axis by hand slow and easy do you feel anything that isn't smooth like silk? That would be it. Feel the stepper is the drive gear tight any slip ?? Any play in the shaft side?

Edit

Looking at the pictures again I'd bet that if you went taller and printed faster, it would be even worse because the bad part got hotter and more bound up more Alternatively printing faster might make it better because you have the inertia to push past the binding spot.

Ig you think that's bad wait until you get multiple retractions going that the rocking motion of the 3kg Is probably going to be enough to pull the filament right out of the extruder.

120grit sand paper give it a scuff and rubing alcohol before each print. That solved almost all of my issues with bed adhesion and let me get away with it where normally it would fail. Anything else it's probably out of level bed or actual frame of the machine has a bend or low spot. If your z offset was bad you would have that happening all over the the first layer. If you have a bl touch on your set up, make a grid amd write down each number if there is a difference in the corners it's bed level If it's middles / sides it's a low spot in frame some materials tolerate out of level better then others.

How isbthe chatter on that? I see the 20 pounds of bungies on the thing

Thanks that actualy helped the should I questions abit. And gave me a good idea with the c clamps.

You gota report that to the consumer goods or something like. They can get fined very big deneros for selling under weight goods. Like it's a realy big deal.

Yeah i crashed it like 3 times already. Does that make me a seasoned veteran? Lucky me it cones with a cutout clutch that has saved , the work, machine and my pants.

Right now It's less so questions as more of I don't know what I don't know.

Tool angles and geometry Is one, is carbide viable for one of these or should I be using high speed steel for boring?

For speeds and feeds do you use the general rules as you would for turning or milling or something else?

Work holding fixtures any recommendations on what is essential to have at the ready? Most used ?

Thanks! That was one of the first things I watched on that machine. Of all the equipment we got over the past few years, this one was just droped off at the door I didn't even get a chance to talk to previous operator.

Yes the work that Curtis does is incredible. And I am in a similar line of work. Just years behind in experience and knowhow.
