i have an Ender 3 that I upgraded to a glass bed. I have to occasionally clean the glass surface with rubbing alcohol to get the filament to stick. Then I have to wait until the bed cools at the end of the print to get the object off as it sticks so well.

Based on my experience with sawing hardwood, air drying a 1" thick oak board takes about 3 years. Thicker takes longer. Oak rounds (any hardwood) will usually split as the wood dries. Saw it in half lenghtwise, let it dry, then glue it back together seems to be the only way to avoid the...

Currently Autocad is a yearly license based package with a price tag of nearly $1500 per year. For that price it should do the work for you. Contrast that with the clunkyness of FreeCAD with a price tag of $0. For a hobbiest doing work for himself FreeCAD seems a better bargain. I did find...

When I built my mini mill into a CNC, I kept the controls available to manual mill with it. There is a learning curve to setting up a project for CNC. The software, however, does not need to be expensive. FreeCAD is a package with CAD and CAM built in. The coltroller I use is an Arduino with...

Making and breaking the contact is spark eroding. Without the tip being moved from the contact it is called welding.

I have a Harbor Freight 4X6 bandsaw. Thoughts I have about it. 1. Reading in a few forums, it seems like most cheaper bandsaws are pretty much the same except for the color and the name on them. 2. Any bandsaw is better than a hacksaw. Miles ahead, 3. To me a bandsaw is to be compared to a...

I may be wrong so if someone comes with different information, don't discard it. Your R8 collets work well on the mill. They hold tools with very tightly controlled sizing. If you were to move to R8 collets on the lathe, you are then restricted to defined sizes. ER collets can close and hold...

I have a mini mill with Arduino CNC control using DRV8825 drivers. One was skipping steps so I increased the current. It was still skipping so I increased the current. Turned out it was skipping steps because it was overheating from the excess current. I reduced the current and increased the...

I'm a beginner too with Arduinos. In your sketch you have two "include" statements, one surrounded by < > and the other in quotes. Some of my programs will not work with the includes in quotes but will if I have them in < >. I don't know why. I've copied some examples to modify and sometimes...

Gears that are properly meshed don't make a huge amount of noise and plastic gears make even less. The gears are mostly there to create the proper ratios for gear cutting and power feeds, not power transmission so plastic gears hold up well in this situation. They can be injection molded gears...

Is it really a sin to be a bit envious? With that mill sitting on the pallet I would be hounding the friend terribly to get it one the stand and ready to work.

Such different lathes that it is unlikely that a person would have used both of them. Decide how large of items you intend to turn, then choose a lathe that can handle that size. That choice would be tempered by how much space you have for it and how you would handle the weight getting it into...

You can change the speed of the Youtube video too. Go to Settings, then Playback speed. Speed ranges from 1/4 to 1 1/2.

The high speed listed for small drills is more of a maximum for the fasted drilling. If making the hole in the least amount of time is critical you want a fast drill. Slower works pretty well. One of the downsides of the slower drilling is that the bit may not evacuate chips as well so peck...

One of my acquantaince's good friend died suddenly and unexpectedly yesterday. Life is short and we never know when our time is up. Buy the little lathe, learn what you can on it, especially how to adjust the moving parts and what tools do what operation. Those will all translate to the...

I have the longer version of that (or very similar) lathe. The drill chuck will attach to a MT2 taper that fits the tailstock. This will fit many bigger lathes too so it won't be wasted. I use a mixture of HSS and carbide insert tool bits. The inserts are shaped correctly and cut very well...

I've been on the opposite side of engineering, trying to repair something an engineer designed. It was probably just fine to be manufactured but nearly impossible to repair. Some engineers are very good at designing for both but I'd say those are rare.

I think you are asking an awful lot from coders. You want them to be engineers with 30 years of experience and coders with 30 years experience too. There just isn't enough time to be both, plus coding for every possibility gets to be such a big program it won't run on most hobbyist's...

Why did Microsoft choose this model for upgrades. I run Linux and it has a little notification in the tray to tells me there are upgrades available. I can choose none, any, or all and can let it do the upgrade while I do other things with the computer. The only time I have to reboot is when I...

I've been raising red clover for seed as did my father. His sayings about red clover was that it was much easier to thresh if it had been rained on while in the swath a few times and that if you could see the combine through the dust, you weren't really threshing. I use a Massey Ferguson 750...
