For now I’m going to run the spindle in isolation at a set speed using the provided power supply and speed controller rather than doing anything clever like letting the electronics handle the speed.

This chip thickness or feed per tooth, along with the number of teeth in the cutter, form the basis for determining the rate of feed.

As there is no longer an extruder or hot bed as well as all the temperature probes that come with that, I removed any references to them in the code.

Used for cutting, copying, panel sizing and any routing applications on solid wood, wood composites, plastic materials and laminates.

I can say the spindle does not need to be changed, this things pretty good for a small machine. Banggood do more powerful ones as well if you need it.

Lets look at the spindle first. It comes well packaged and 2 has 2 short wires with bare ends as well as a nice aluminium mounting block.

The hardness of the cutting tool material will also have a great deal to do with the recommended cutting speed. The harder the drill, the faster the cutting speed.  The softer the drill, the slower the recommended cutting speed (See Figure 2).

I got rid of it and replaced it with a piece of plywood so its cheap enough to cope with a few holes and be replaced if necessary as well as being fairly dimensionally stable.

On the milling machines we have here at LBCC, the feed is independent of the spindle speed.  This is a good arrangement and it permits faster feeds for larger, slowly rotating cutters.

The glass print bed is great for holding down your 3D prints but the idea of a rotating carbide endmill crashing down on it scared me a little so I knew this had to go.

Once the SFM for a given material and tool is determined, the spindle can be calculated since this value is dependent on cutting speed and tool diameter.

When drilling and tapping, it is crucial to use oil.  It keeps the bits from squealing, makes the cut smoother, cleans out the chips, and keeps the drill and stock from overheating.

The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter.

And for the first cut I inserted a 3mm end mill piece also from banggood. I’ve not used any of their tool bits before but have found them to be great value if you don’t mind waiting a little longer for them to arrive.

In this case an old RAMPS board with an Arduino mega controls the various motor directions as well as telling the extruder motor how much plastic to squirt out and when.

I really wanted to make this work with the printers existing electronics and it kinda’ does. It’s not easy to reconfigure however and the software I’ve got loaded is nearly five years out of date.

I also switched to something that’s designed to run a CNC, the openbuilds control software. Again this is free and easy to use.

I knew immediately the cables would not be long enough so I soldered on some additional length and then set about testing the spindle to make sure it worked well.

Tap guides are an integral part in making a usable and straight thread.  When using the lathe or the mill, the tap is already straight and centered.  When manually aligning a tap, be careful, as a 90° tap guide is much more accurate than the human eye.

I thought some limewood would be ideal for the first cuts since its fairly soft and I made sure it was extra secure on the bed this time.

I ditched the RAMPs board and the Arduino and switched to a dedicated CNC board that runs the latest builds of GRBL, runs 3 axis and is of course available from Banggood (sorry if this reads like a giant ad, I just buy a lot of my stuff from them!)

I used some firmware that already been written called GrblforRAMPS by Per Ivar Nerseth but had limited sucess and messed around with the latest Marlin build with some tweaks.

Pecking helps ensure that bits don’t overheat and break when using them to drill or tap.  Peck drilling involves drilling partway through a part, then retracting it to remove chips, simultaneously allowing the piece to cool.  Rotating the handle a full turn then back a half turn is common practice.  Whenever the bit or tap is backed out, remove as many chips as possible and add oil to the surface between the drill or tap and the workpiece.

3D printers do additive manufacturing using a plastic extruder usually and CNC machines a rotary cutting tool to do subtractive manufacturing by carving away the unwanted material.

It was a good printer for its time and as I built it myself I’m very familiar with the design so it’ll lend itself perfectly to this project.

My first thought as I’m sure many have considered before, there isn’t much difference between a 3D printer and a small CNC machine.

The 3D printer I’ve a few years now just sitting in the shedas I have my nice Lulzbot Taz 3 so its about time I gave it a new lease of life.

It made sense to use a shape I’m familiar with so I used the makerspace logo again, but scaled it up a bit so you can see the detail with a 3mm bit. I didn’t have anything smaller at this time.

Company is registered in Mumbai (Maharashtra) Registrar Office. EST Tool Steel Private Limited registered address is B1005, Cello Triumph, IB Patel Road off.

So I learned loads making this thing, for light cuts and engraving its actually a useful machine but you can see from the wobble its not really suitable as a serious CNC.

The extruder also had to be removed as well as all the associated wiring like the heater cables and temperate probes which made things a bit easier to deal with.

I then tried a stamp. I used rubber material at first designed for laser cutting but this was too soft and didn't work well so I switched to something a little harder; linoleum.

Drilling machines that have power feeds are designed to advance the drill a given amount for each revolution of the spindle.  If we set the machine to feed at .006” the machine will feed .006” for every revolution of the spindle. This is expressed as (IPR) inches per revolution

I did have some trouble with the connections, partly because the PSU labels were in Chinese but this was nothing a quick google couldn’t fix. I'll post a picture showing what wires go where.

You can just I just pick what material you're, using, tell it how big it is, add a pattern or something that you want to cut, tell it the depth and can generate the tool paths.

Feed per tooth, is the amount of material that should be removed by each tooth of the cutter as it revolves and advances into the work.

As the work advances into the cutter, each tooth of the cutter advances into the work an equal amount producing chips of equal thickness.

Feeds for end mills used in vertical milling machines range from .001 to .002 in. feed per tooth for very small diameter cutters on steel work material to .010 in. feed per tooth for large cutters in aluminum workpieces.  Since the cutting speed for mild steel is 90, the RPM for a 3/8” high-speed, two flute end mill is

I just move my spindle to a reference point, say the bottom left corner on top of what I want to cut, set this as my home position and then start.

I've considered adding some powerful motors, changing the plastic parts out for something more rigid, change the belts to lead screws and maybe redesign the structure to add to its rigidity.

The flex in my tape mounted spindle was pretty bad during that though so I should probably make a more serious mounting bracket.

I made a video sponsored by Banggood who have given me a $100 CNC spindle and some tooling to try and make my old Prusa i3 3D printer into a CNC.

The banggood spindle comes with a nice mounting bracket that means I just need to drill a few holes in the existing mounting plate.

I switched from Estlcam to Inventables Easel as its free and extremely easy to use, much simpler than anything else I've used so far.

Cutting speed is defined as the speed at the outside edge of the tool as it is cutting.  This is also known as surface speed.  Surface speed, surface footage, and surface area are all directly related.  If two tools of different sizes are turning at the same revolutions per minute (RPM), the larger tool has a greater surface speed.  Surface speed is measured in surface feet per minute (SFM).  All cutting tools work on the surface footage principle.  Cutting speeds depend primarily on the kind of material you are cutting and the kind of cutting tool you are using.  The hardness of the work material has a great deal to do with the recommended cutting speed.  The harder the work material, the slower the cutting speed.  The softer the work material, the faster the recommended cutting speed (See Figure 1).

I measured up a bit of walnut, cut to size and drilled holes to fit the existing x carriage and holes for the aluminium mounting block.

You also get a power supply and variable speed controller allowing the spindle to be ran at anywhere between 1-3000 RPM.

I tried acrylic with a little cut of Olaf from Frozen. It was a bit too melty as I was using cheap dremel bits but still was a good recognisable cut.

They typically both have small stepper motors that drive a tool end of some kind along several axis to reproduce a digital file.

Well a lot it turns out. My steps per inch was off and I had a major crash of the spindle into the bed causing lots of smoke :(

I found it cut but bit of a weird step feature which I knew was not missing steps or a sliped belt as the artifact was not repeated. After some comments from my subscribers I think this was down to the flex of the bed.

Depends on material, diameter you're cutting and your tool you're using. Try something around 300–600rpm-ish will be a good starting point, take ...

I used Repetier to drive the machine as that what I used on this printer before and I know it works. Its free and fairly easy to use.

I used Estlcam to generate the toolpaths as it can generate Marlin compatible gcode and again, its free and easy to use.

The current firmware on this board was on old version of Marlin since as awesome as Marlin is, it was designed for 3D printers not CNC mills.
