Have you ever considered a Z-Axis counterbalance for your CNC machine?
Most commercial VMC’s use one.  Here’s a Hurco VM1:

Easy Multiple Spindle Options for G-Wizard

auxilliary high speed spindle

It’s fairly common to find machines that have multiple spindle options available.  I don’t mean that you can specify multiple, options, but that there are actual multiple options delivered with the machine.  A very simple example would be multiple pulley ratios.  More exotic would be sub-spindles, for example a high-speed auxiliary spindle or speeder on…

Shopmade Tool: Accurately Measure Bores With an Indi-Calipers

shopmade dial bore gage

One of the most accurate ways to measure a bore is with a dial bore gage, but these can be really expensive and seldom used tools.  A nice Mitutoyo dial bore gage set is almost $400 as I write this.
I loved this gadget by gbritnell I saw on HMEM to adapt a DTI to…

Keep Your Tools Safe With a New Tool Check-In Procedure

Aug 24, 2016   //   by Bob Warfield   //   Beginner, Blog, DIY CNC, Products, Techniques  //  2 Comments
Rust preventative

I like new toys as well as the next guy, so I try to take reasonable care of them. Towards that end, I’ve adopted a standardized “check-in” procedure for my shop. When a tool arrives, it is logged into an Excel spreadsheet. I have pages for tooling, consumables (cutters, abrasives, fluids, etc.), and stock (aluminum,…

We last surveyed CNC Control market share back in 2012, so it’s been 4 years.  We got over 250 survey responses, so let’s take a look at the results.  For those who are wondering, recall that the CNC Control is the hardware and software that takes g-code and uses it to control the CNC machine.…

Rough Cutting: The Limiting Factor in Your Shop?

Aug 11, 2016   //   by Bob Warfield   //   Beginner, Blog, CNC Projects, DIY CNC, Manual  //  6 Comments

If you ask most home shop and DIY machinists what the limiting factor is in their shop, I suspect they’d respond that they need a bigger mill or lathe, or they need their first mill or lathe, or they need more room, or something along those lines.  Years ago, when I was starting out as…

Set Up G-Wizard for Small CNC Machines

Jul 29, 2016   //   by Bob Warfield   //   Beginner, Blog, CNC Router, DIY CNC, FeedsSpeeds, Products, Software, Techniques  //  8 Comments
Runout vs Tool Life

I get asked all the time how to set up G-Wizard Feeds and Speeds Calculator for small machines that aren’t very rigid.  Folks know intuitively (or after finding out the hard way) that these machines often can’t handle feeds and speeds that are as aggressive as other heavier machines.
G-Wizard has a well-designed set of…

5 Great CNC and 3D Printing Posts From Reddit

Jun 28, 2016   //   by Bob Warfield   //   3D Printing, Blog, CNC Projects, DIY CNC, Techniques  //  3 Comments

I’ve been spending time over on Reddit lately.  It’s a great resource that uses the Wisdom of Crowds to curate content.  What I mean by that is they not only vote content up and down, but they’re very strict about posting.  Nothing too spammy or too troll-like is tolerated.  Having dealt with some online communities…

We’ve published a couple of articles on vacuum fixturing in the past and they’ve been among the most popular long term posts we’ve done.  It’s no wonder as vacuum fixturing can be extremely convenient to use.

About 65% of our respondents are Hobby Router users and 35% are Professionals.  That’s a pretty decent mix, skewed more to the Hobby side than our usual surveys.  Overall,…

Bootstrap Your DIY CNC Mill Conversion With a 3D Printer

May 18, 2016   //   by Bob Warfield   //   3D Printing, Beginner, Blog, CNC Projects, DIY CNC  //  2 Comments
3D Printed DIY CNC Motor Mount

One of the problems with getting started with a CNC Conversion is not having a CNC to help you make the parts.  You can find kits, which are very helpful.  You can try to manually machine the parts, which is entirely doable.  I did some of both for my first CNC project–an RF-45 mill conversion.  …
