Great machine. Have been very reliable over the last 2 years.
I love my Shark HD4. My only complaint is I wish I had bought the bigger model. I’ve owned it for 2 years now, use it on a regular basis and have not had any problems with it. I would highly recommend it. It was easy to set up and the software it comes with is very good. Lots of available how to videos on utube for the machine and software.

Amazing intermediate/hobbyist machine
I consider myself an intermediate woodworker. I don't know everything, but I do know my way around the shop. This machine does require mainly technical knowledge. So, if you barely even know how to work the wood, you will be fine. Vectrics has tons of tutorial videos on their website that will aid you in mastering the software. Also, GET THE TOUCH PLATE! It is a huge help. The smoothie plus plaque was my first real piece besides playing around with some scraps beforehand. Definitely recommend if you're trying to take a hobby to the next level.

If you have the space and a little extra cash, go with the extended table
So far so good. Fun tool to use but for an old guy like me, programming can be challenging.

Impressions after first week.
First off, I am a retired engineer who designed and commissioned several factory line testers during my career. I have seen many creative ways to kill things so some of my comments are based on that.

This is my first CNC machine so I outside of a lot of research I am not comparing it to anything. These are my impressions so far. Most of the comments below are things I am in the process of updating myself.

CNC Shark HD4:
1. Overall the machine is very well build and very well packaged. It comes in two boxes with one, the base, weighing 110 lbs. UPS delivered it so not sure what all the brew ha was about a lift gate.
2, Putting it together was simple, I did it myself with just a bit of planning.
3. The need to enter a code, supplied by NWA after sending codes to them, is in my opinion downright weird and hokie. I nearly lowered my review of the machine by one notch just because of this. I have since noted (by doing a very specific search) that some users have had ongoing issues with this, had I know this it might have influenced my decision.
4. The lack of cable relief on the cable running to the X axis motor is a disaster waiting to happen. The strength of three tiny wires are all that stands between an errant foot and testing your soldering skills. This is being fixed on my machine.
5. There is a nice cable chain for the Z axis cable which is large enough to also accommodate the rotor/spindle power as well as the spindle cooling lines. It would be really nice if there were also a cable chain along the left side of the machine to accommodate all the cables / water lines that end up hanging over that side. This is being fixed on my machine.

1. It would be nice if the spindle used an ER20 instead of an ER11 collet. There are times 1/2" shank bits would be nice (for a wider resurfacing bit for example.) I have seen spindles on eBay with the larger collet that would like fit (and work with the controller) so this upgrade may happen if this becomes an issue but is something NWA should consider.
2. The included water lines should be about 5 feet longer to allow better "cable" dressing such as routing through the cable chain(s). It is easy to cut off extra, not so easy to add.
3. The lack of control for spindle rotation from the CNC controller is a nasty oversight. I have been treated to a nice "ping" and damaged workpiece twice now when I forgot to start the spindle. Less than five minutes of research and a few parts from Amazon and Digikey are about to solve this problem but NWA should have included that in the package.
4. This is not a comment on this machine but a comment on "hobby" CNCs in general. Throwing a pump into a five gallon bucket of water, even one that is covered, in a environment that is not exactly pristine is asking for trouble. While I am currently running that way I have a CW-3000 water chiller on order. This will make the cooling system closed loop.

All that said I am having a blast using this beastie and with a few simple upgrades will have it exactly the way I want it.

I did upgrade to VCarve Pro (costs $350 once you have registered VCarve Desktop). I did this for several reasons but the main ones were the ability to combine toolpaths and the ability to run "gadgets."

Attached is a photo of one of the clock gears I cut with it. This was the third project I tried (and one of the main reasons I bought the machine.) It was MUCH funner drinking coffee and watching the machine do the work than hunching over the scroll saw for two hours hoping a tiny mistake does not ruing the work.

good machine so far but lack of good instructions on software
I think it's going to be a good machine and they have a lt of videos on the software but it's hit or miss as to weather it will answer your questions. There needs to be a video orinstruction sheet that explains all the icons one by one.

The good and the bad
I am into about a month of use. It took a few mistakes to learn the software but the learning curve is shrinking. Assembly: The instructions are absolutely useless. I had to search endlessly on youtube to just get it set up and I still cannot get the software License to load. Every time I open it I have a pop up box to register it. It comes with cheap Chinese bolts for assembly and the heads strip easy so be carful. The water cooled spindle is worth it. Smooth, strong and very quite. I would purchase it again. I have it all dialed in now and I'm very happy with it.

Good machine but extremely expensive and software won't allow full use of the stated workable area.
Overall solid machine. I have the water cooled spindle with it as well. On the table I have it on it does not shimmy or slide around while in operation. Although I will lock it in with some blocks just incase. On the disappointing side the instruction booklet is miserably inadequate. So for someone not so mechanically inclined it may be a miserable set up. Also do not expect to get full use of your table. The gantry travel from the back will eat up some and side to side will take a little away. It says you can machine a 25x25 inch area with the standard bed. BUT that is not the case because the Desktop version of Vcarve that come with the unit only allows 24x24 inch of travel. You can get your extra inch in the X and Y axis with a approximate 300 plus dollar software upgrade. Aside from that the software is quite easy to use and the companies website has numerous video tutorials to help one get the feel and flow of the software. I did call manufacturer about why the desktop version of the software instead of the pro version so one could get the most the size of bed they were shipping with the unit. They emailed back because of the price differential between the 2 versions they choose the desktop version. I guess they had already over priced their unit and adding the proper software would make it look even more over priced. That's my only beef.

Can you attach a laser engraver?
Brad H on Feb 8, 2017
BEST ANSWER: Yes there is an attachment that allows you to laser engrave pieces
Does the Shark HD4 only work with the Vcarve Software? Can I use a different CAM software and send it to the Shark HD4 Controller?
Joey G on Sep 5, 2017
BEST ANSWER: Check the Fusion 360 forums to see if a user wrote a post processor for it. Fusion is free if your business makes less than 100 grand a year. It, however, adds several layers of complexity compared to V-Carve.

V-Carve has incredible tutorials and a strong user base. V-Carve is quite competent and fits very well with the capabilities of the Shark.
Can the Shark HD4 with the water cooled spindle also use one of the other compatible routers with 1/2" collets?
Dwight S on Feb 6, 2017
BEST ANSWER: The spindle clamp on the HD4 is designed to hold a router or spindle with a diameter of 3.5".

The 2 HP water-cooled spindle (Item 57346) has a 3.5" diameter, so they are interchangeable.

Routers, including the Bosch 1617, Porter Cable 890 and DeWalt 618 will also fit in the mounting clamp and offer both 1/4" and 1/2" collets.
Does this need a router at all? Can you cut completely thru wood to cut out letters?
Mary B on Mar 29, 2019
BEST ANSWER: Yes. It either needs a router or a water cooled spindle. Check the manual for the model CNC machine you are using for the correct make/model of router as not all will fit.
You can cut all the way through but to do
so you need to have a piece of scrap wood under your work to protect the table surface from the blade. You will also need to design your layout so that there are tabs connecting the letters to the remaining material that you will then cut by hand once the machine is done. This allows the letter to be held in place while being cut. Some people is double sided tape to hold the work in place or even well placed brads.
Can the water cooled spindel take a 1/2” bit ?
Ken A on May 9, 2018
BEST ANSWER: The water-cooled spindle shaft will not hold a bit with a shank larger than a 1/4" .
Is the software easy to learn?
Steve P on Apr 23, 2019
BEST ANSWER: I sold mine because Of the software. There are videos to watch but you will need to spend a substantial amount of time to learn the software. Watching the videos is like watching paint dry.
Can the Water Cooled spindle be adapted to the Extended Bed version of the Shark?
The Shipwright on May 10, 2017
BEST ANSWER: I would think so. The only difference in the regular bed and extended bed is likely the length of the bed and rail system used to move the gantry. The spindle mount should be the same on both version as that should not need to be changed just because of a length difference. I will say that the mount originally installed on mine was for the router base I had to change the to the spindle adapter that was included. It is a right fit for the bolts so take your time as the mount is plastic and can deform with tightening. I would also use some locktite and extra washers ( to disperse the pressure more evenly) as the mount is again thick plastic and tightening down the bolts can start to deform the plastic if not careful. There is plenty of tubing for connection of the spindle and the pump used to cool it.
Can I write on steel like a knife ?
Patrick C on Jun 16, 2019
BEST ANSWER: I have not etched on steel, but, would think this should be feasible, you can etch on glass and granite, etc. Limiting factor would be the availability of a ¼ ubxg bit for the router that will etch steel.
Does this machine come with limit switches ? If not do you offer a package with limit switches ?
Splinejunky on Mar 17, 2019
BEST ANSWER: This machine does not utilize limit switches. The Axiom line of CNC machines do utilize them.
Can you use antifreeze instead of water? I live in a freezing climate during winter
Eric on Jan 25, 2019
BEST ANSWER: I just use tap water and then empty it out each time and blow air through the tubing to clear it out. I have heard of people using antifreeze and even different types of algicides. Not sure if the the antifreeze will damage the internal parts. That you would have to look or contact the spindle maker.
Is there anyone in Wisconsin that hasone ???
Duane W on Dec 3, 2018
BEST ANSWER: Hello I live in Illinois and just bought one and have loved the machine itself. It could be built a little heavier so that the motor doesn't bounce so much. I would highly recommend the water cooled spindle it is super quite, and the readout screen for the motor rpms is very helpful.
