I've skimmed the owners manual and it appears that spindle speed control is an option that may not be present in your machine. Reread page 7 about the setup and the options that can be included to see if setting the spindle speed in software is available on your machine.

You probably only need ferrite beads on one or two wires but there is no way of knowing which wires need them so best to do all 8. If you are wrapping wires with aluminum foil you don't want to wrap all of them together. The signals the wires carry are digital, either on or off and the spikes...

Great idea. Instead of trying to fix a minor problem, go to a completely different system and learn all the problems that that system can also create.

3 feet of wire can make a pretty good antenna for picking up random signals. You might have better results if you use shielded wire for all connections to the Arduino. Quick way to find out is to use aluminum foil to wrap around the wires for shielding.

Some people have good hand/eye coordination and find that a manual mill works best for them, especially when doing a "one off" project as CNC takes plenty of time for setup and from then on saves time as it repeats exactly so you get multiple products that are the same. Some of us have...

You just described tramming the head of the mill perfectly. Now you know what tram is and that your mill is in tram.

I'm no expert but two things come to mind for why a stepper motor makes noise and doesn't rotate. One is too fast of pulses and the motor can't keep up. The other is reversed leads on one of the coils so the motor steps one way and then tries to step back. I'd try reversing the polarity of...

The real reason that parting with the tool upside down on the back side is that every moving part of the lathe must have some slack in it. If you tighten the gibs until there is no slack, you can't move the cross slide or compound so you loosen them just a little. When you cut on the front...

If you hold the material and try to drill the drill will choose its own path and may exit the side of the material before it gets to the end of the material. Drilling on a lathe, the drill will try to self center in the material. By using a pilot hole, then increasing the drill size you...

I've been using Fusion 360 but it required a 64 bit OS which meant Windows 10 for me. I hate Windows 10. Then I saw a Youtube on Designspark and it will work on a 32 bit OS which would let me go back to Window 7 that I have installed as a 32 bit. The video makes it look good...

Unless you are in a hurry to get the machine set up you might wait to install the gas struts. I read someone's post that said his setup worked better without the gas struts. You could decide to add them later if you wanted.

I found little information on how to size the stepper motors for any axis as I attempt to CNC my SC 2 mini mill. I finally just bought some NEMA 23 with 650 mNM holding power that require a maximum of 2 amps. Fastening one directly to the X axis I tried milling aluminum and found that it had...

You might be able to contact Walter Maisey by using the conments on the Youtube video you watched. Sometimes the person making the video reads and responds.

Any time you use free software you are subject to finding that the company eventually may want paid for their work. Autodesk has Fusion 360 for free to hobbiests and startup companies that make under $100K per year. That too may become a paid subscription but in the meanwhile it is quite a...

This happens, you are dealing with an individual and taking a chance. However, I consider it a fair trade as I have bought so many things that would have cost way more locally if I could even buy them that it has way offset any losses I have taken.

If you are into production and need to make threads that fit what someone else made, single point threading can be more difficult as have to make the threads match someone else's threads. If you are doing a one-off for yourself, single point is easier as you can make a thread and then test if...

If you are in a production shop, time is related to money and the faster you can produce the parts, the more profit there can be. With that in mind, pushing the lathe to the max that produced acceptable parts is desired. In the past, that speed was limited by the use of the steel cutter that...

My experience is limited but buying a machine that is too small seems to be a much worse limitation than buying one too big unless space is limited. I have a hard time turning a 10 inch diameter bar on my 7 inch mini-lathe.

With my Woodmizer bandsaw mill that knock was the first indication of a cracked blade followed quickly by a broken blade. Examine your blade carefully and see if you don't have a cracked blade. Too hard of steel being bent on the way around the wheels will do that. You may need to change...

Heavier weights, longer arms, aerodynamic shapes? Where will it end? Looks like a fun project.
