If you encase it, have a $50 vortex separator,a shopvac and suck it up when it piles up you’ll be good. I’ve had it accumulate in single jobs to the point the machine stalls from all the chips :) That idea does depend on how well these things handle dust though since my machine uses bushings and not ball bearings.

As well as demonstrating an extensive range of innovative solid carbide tooling solutions, Guhring engineers will be on hand at MACH to discuss the scope of special tooling solutions that can be designed, developed, manufactured and trialled at the Guhring facility in Birmingham. Guhring UK has a team of expert engineers that can create productivity, cost, inventory and cycle time savings for UK manufacturers.

The new RF100 Sharp demonstrates extremely smooth cutting action and chip removal and it is also an extremely flexible end mill suitable for slotting, ramping, roughing, helical milling, finishing and trochoidal cutting. The smooth cutting action combined with the potential to be used in a wide variety of applications makes the new RF100 Sharp, the end mill of choice on challenging material types.

From a dimension perspective, the new RF 100 5 and 7 Speed are available with cutting diameters of 6, 8, 10, 12, 16 and 20mm with a necked diameter that permits cutting depths from 20 to over 60mm depending upon the diameter selected.

I just went through the process and shipping to CT was less than $17. Maybe it costs more to get it to the moon.

It sounds as if you have never used a 3D printer. In comparison, the 3D printer is much quieter than a CNC mill with the noise of a spindle and bit cutting through material. I have one of each, the noise of the 3D printer is quieter than the Television and very tolerable, the noise of the CNC: not so much.

Shapeoko2 is very unreliable. Lots of modding to make things work properly. It’s a poor job for the SECOND version of a CNC machine. All they did was make a few mechanical changes from Shapeoko orignal. Advertised NEMA 23 motor operation which they act like they have never tested it 3 months after I bought mine. I suggest waiting for another option.

I’d guess a 1/8th endmill could do 10IPM at 2mm depth of cut with reasonable surface finish. Rigidity is the limiting factor though, in a proper machine you could probably run a quarter inch deep at 400IPM given proper chip clearing.

The Shapeoko 2 is available in two versions, a $300 mechanical kit that requires you to go out and get some motors, a power supply, and a grblShield, the full version, for $650, includes everything you’ll need to start routing wood metal and plastic at home.

Probably not. A Dremel moto-tool is a pretty lousy spindle. Thing probably has a particle board base too. Most of these things do.

I’d like to get one of these to mill 1/2″ acrylic. I’m not really interested in milling wood as much. Does anybody have enough experience with cutting acrylic to know if speeds/feeds are reasonable for a machine like this?

If you went with a Proxxon or better spindle and so forth it might work. Runout on a dremel is TERRIBLE. I use a dremel for some sanding but past that and some grinding it’s bad news. MDF is actually a great substrate for building a CNC machine if it’s done properly, and it’s fixed bridge. If your adventurous you can buy a BBox kit (you cut up the MDF) from Microcarve’s very own John, and it will be very nice for PCBs, fine lithos, and other things. I’m not associated with him other than after two years I’m still emailing him questions from time to time.

Yes this machine can do acrylic. With the dual motor now on the gantry it may even do aluminum, so long as the spindle can run low enough in rpms.

Wow thanks for this info, I just found the local supplier for Proxxon. I’ve preordered the Shapeoko 2 and you just saved me from spending on another Dremel

3D printers are noisy and leave behind more than a little extra plastic for all but the simplest shapes. Cleaning is a part of making.

Following the success of the Diver Series of end mills, Guhring has now extended the benefits of this industry-leading series to the micromachining sector with the new RF100 Micro Diver. The new micro-precision milling range is a universal tool for every material and application. Providing plunging and milling in a single tool, the new RF100 Micro Diver permits extreme cutting values with very highly cutting depths. Available in two variants, the 6808 and 6809, the RF100 Micro Diver features a symmetrical drilling face for stability when ramping and drilling, a new transition geometry to improve rigidity and an innovative flute form that further enhances rigidity and eliminates vibration.

The 4-flute end mills are suitable for machining steel, stainless steel, aluminium, aluminium alloys and other challenging materials. Available in three versions, an extra-long design long (DIN+) that is an extension on the long (DIN) version but has an even longer cutting edge and there is also a standard length end mill. The RF100 Sharp is offered in all common sizes up to 20mm diameter. Depending upon the chosen diameter, the RF100 Sharp is supplied with an overall length from 50 to 104mm with a flute length from 3 to 41mm.

I can cut with a .125″ endmill at .25″ at 35 IPM with my Microcarve machine. It’s a terrible idea, but it’s happened before. More realistically I do .08″ DOC with a .125″ at 80 IPM and .14″ DOC with a .25 endmill.at 140 IPM. I thought about the Shapeoko and super-sizing it but it’s rigidity could be questionable for anything that requires a lot of it.

Well, if we’re going through the trouble of mounting it on the wall, why not mount it upside down? That’d resolve the whole chip-clearing issue. :)

From its extensive milling portfolio, Guhring will be giving a MACH show debut to the impressive new RF100 Sharp Series of high-performance end mills – and this range will be put through its paces on the Grob to emphasise the performance characteristics of the end mills. Designed to address the issue of machining soft, tough and high-alloyed materials that create an issue with swarf clearance, the new RF100 Sharp Series is Guhring’s sharpest solid carbide milling tool to date.

For all the 3D printers that hit the Hackaday tip line, it’s surprising we don’t see more CNC routers. They’re arguably more useful tools, and with the ability to mill wood, plastic, and non-ferrous metals, open up the door to a whole bunch more potential builds. One of the most popular – and certainly one of the least expensive – CNC routers out there, the Shapeoko, just received a huge update that makes this minimal machine even more capable.

The RF100 Micro Diver Series is suitable for cutting materials up to 48HRC at depths up to 5XD. With a 40degree helix angle to evacuate chips from the work area when conducting high-speed machining, the Series is available with a cutting diameter from 0.79mm to 3.175mm with a multitude of dimensional increments available.

http://www.makerslideeurope.com/eshapeoko-kits.html I purchased an eShapeoko kit several months ago. These guys had all of the updates that the eShapeOko 2 has, but long long ago! I am very happy with the kit. They are out of the UK, I had it delivered to Spain.

Hm… I’ve already got an Uno, a grblShield, a power supply, and a Dremel. Shall I or shall I not? Decisions, decisions…

I cut 5mm and 1/8″ acrylic on my modded Shapeoko (basically it’s a somewhere between V1 and V2). It works. I’m not sure about 1/2 inch. Can you find two flute bits that long?

This will never cut aluminium cleanly. I’d be suprised it it cut acrylic at a reasonable speed. I think these should only be considered engravers, theres just not enough rigidity in it.

Guhring will return to the MACH exhibition at the Birmingham NEC. In Hall 19 on Stand 210, the cutting tool manufacturer will be introducing new product lines alongside established industry-leading ranges. The Guhring stand will showcase a complete range of threading, turning, drilling and milling tools, many of which will be live cutting at MACH on a Grob 5-axis machining centre that will be on the Guhring stand.

yeah im still debating the mechanical kit, it just seems like theres a lot of mechanical bits you still need.. weird.

The optimal cutting conditions for the RF 100 5-Speed is applications on all tough materials up to 1200N/mm² and where a ramping angle of up to 10° is required. The innovation is also perfect for slotting with cutting depths up to 1XD and helical milling. Whilst the RF 100 7-Speed is also the perfect choice for tough materials up to 1400N/mm², the seven fluted variant is also ideal for helical milling at in-feeds of up to 0.05XD ap per cycle.

My tip – always get good quality cast acrylic. Extruded acrylic is very hard to mill as it melts too much. Cast acrylic is a joy to use on my Proxxon MF70. Extruded acrylic will laser cut but not as well as cast and it smells a lot worse. My wife shouts at me when I laser cut extruded acrylic and then complains that I smell bad when I come to bed. Sex is not an option.

Appearing alongside the new ranges will be established lines like the RF100 5-Speed and RF100 7-Speed solid carbide end mills. Developed for the machining of very tough materials, the RF100 5-Speed and RF100 7-Speed solid carbide end mills take cutting speeds and process reliability to a new level. The increased tooth number of the five-fluted 5-Speed and seven-fluted 7-Speed generate high metal removal rates with stable process reliability, even when processing the most difficult-to-machine materials. As part of the highly dynamic Guhring Trochoidal Cutting (GTC) series, the new RF100 5-Speed and RF100 7-Speed are perfect for machining tough stainless steels, special alloys and a wide variety of steel and cast-iron grades.

Also, on show at MACH will be the Ratio® line of roughing end mills. With flat crested geometry and an optimised roughing profile that demonstrates 60% longer service life, the Ratio® high-performance roughing cutter has several geometry adjustments aimed at providing performance. The Ratio® increases material removal rates with its asymmetrical cutting flutes that reduce cutting pressure compared to smooth cutters.

Doh! Acrylic. I was doing corian at 45 IPM with a .125″ 2 flute spiral solid carbide endmill at .1″ DOC. That was taxing on my machine, I think something like this might buckle at that speed.

The new Shapeoko 2 keeps the same V wheel on an aluminium extrusion design with Makerslide, but fixes a few problems that limited the original Shapeoko. There’s a larger work area on this version, and the Y axes feature dual stepper motors. The biggest feature, we think, is the ability to handle materials larger than the machine itself thanks to its open front and back.

You’d be putting extra torque on which ever stepper has to lift the gantry. You could put a counterweight, but then you’d have all that extra inertia to deal with. Technically, yes, you can do that, but it’s not going to work well.

Well, I can put a 3D printer in my house and other than the ugliness of the machine, it’s fine. I can’t put a CNC machine unless I want to deal with chips of plastic/wood/aluminium forever.
