Cricut Repair Info
One way to get yourself a cheap Cricut machine is to buy a busted one off eBay. Try searching for both "broken cricut" and "defective cricut". Often you can win one for as low as $0.99 plus shipping for a Personal or Create model, or somewhat more for an Expression. Unfortunately, the supply has greatly dwindled over time since they stopped making the original three models.
Where to get one
The main dealer of these machines, "websbestdeals," must have some exclusive arrangement with PC, because they (used to) seem to have a pretty inexhaustible supply of broken machines to sell.
Have patience and don't get carried away with your bid, it seems there will always be more listed within a few days.
Read the seller's description carefully to see what is included. Usually (but not always), they only include the power supply, but sometimes it comes with everything, cutting mat, blade holder, power adapter, cartridge, overlay and even the manual and warranty card. Once in a while they'll sell two for one, but missing one or both power adapters.
Sometimes the seller's description will tell you exactly the issue, as in the case with a dragging blade. I'm not quite sure yet what it means when "the blade makes a lot of noise", but the broken limit-switch wires definitely cause a horrible noise on startup. Many times they simply say "it has no power," which so far often (but not always) indicates a power supply or broken trace problem.
Mine didn't come with a cartridge!
If you don't have a real cartridge, you can make yourself a "Fake George" to at least get a machine with the stock firmware to start up fully. More details here. Basically, you just need to (carefully!) make something that will short together pins 4, 6, and 10 (or 11, 15, and 17) on the cartridge port, to fool the machine into using its own built-in "George and Basic Shapes" cartridge.
Here are some close-up photos of what a real "George" looks like inside.
Removing the Side Covers
Don't rush to take the sides off the machine. Many times this won't be necessary, and it's hard to get the trim pieces off without doing at least cosmetic damage.
The way I do it is to use a thin bladed putty knife to get in between the trim and side cover (from the outside edge inwards), while pulling outwards with your other hand, to depress the little fingers that clip the trim piece on, one at a time. I've broken off quite a few of them with poor technique, but don't usually bother putting them back on anyways.
Once the trim piece is off you can get access to the 5 or 6 phillips-head screws holding the actual side cover on.
Accessing the Motherboard
Usually all the action happens in the bottom of the machine where the motherboard is located.
To access it, all you need is a long #1 phillips-head screwdriver. Roll the machine onto its back on a towel or something else soft, and remove the 8-or-so most obvious screws around the outside of the bottom cover. Then, tip the cover down and towards yourself like opening a panel. If you carefully tug a little on the wires leading up into the side covers you can get just enough slack to be able to rest it flat on the table while the machine is still on its back.
Problems and Solutions
Here are some of the things I have discovered so far while fixing a bunch of these machines:
I don't have a schematic drawn up for these, but one of my Creates is an older model with only a 2-layer board. This makes the circuit far easier to figure out than the 3-layer boards that came later. The Expression board is nearly identical, so this should be of assistance for figuring out those issues as well.
Broken USB Port
Many people have reported broken USB ports. Although I have never attempted this myself, others have reported success at replacing the part.
It seems the dials are pretty easy to break if the machine falls onto its front side. The size dial is expendable if you use Make-the-Cut or other cutting software on your PC, but if you cut with cartridges or the pressure dial is broken you may not have much choice but to try and find a replacement dial.
Bad Power Supply
An Expression I got with a bad power supply would constantly turn on and off, like a turn signal on a car. On, off, on, off. Replacing the power brick with a known-good one from another machine solved the problem.
Broken Inner-layer PCB traces
So far, two Create machines have been suffering from broken traces in the middle layer of the circuit board. Fixing these can be challenging since you can't see the inner layer to know where it was supposed to connect to.
Fortunately, I have a working older revision of both Personal and Create motherboards that are only 2-layers, and there were virtually no changes to the parts connections or positions when PC switched to the 3-layer boards. This means you can visually trace the connections on the older board, and verify those connections on the newer (broken 3-layer) one.
I will be adding specifics here to help with this process for anyone who doesn't have the benefit of a 2-layer board for reference.
1) One machine's power button would light up when you turned it on, but nothing else would happen. This was isolated to two broken inner-layer traces leading from the 5V regulator to two nearby parts.
Replacing Drive Belt in Cricut Expression machine. (contributed by Derek N)
I successfully found and replaced the belt on my “warrantied” machine that the company had me cut the drive belt. It was simple, took about 20 mins.
Purchase the belt by the meter @ http://www.robotdigg.com/product/22/MXL-Belt,-6mm-Width-Open-Ended. You need to email the company before ordering online and they will send you a paypal payment request. You need 2 meters. Delivery took 20 days from China.
How I did it:
With the cut belt still in the machine, I took the cut side and stapled (with several staples) the new belt in the same alignment as the old belt. I then pulled the belt through very carefully because you do not want to have to open this machine up. After I had the belt fed through I disconnected the metal clip that attach the belt to the cutter. I did one side first, then hooked it to the drive. After this was done I pulled it tightly so I could determine the length that I needed on the other side. Once I completed this I then made a judgement call, I wanted the belt tight (to were I had to give it a little tug to fit it to the drive mount). I then temporarily affixed the other metal holder to the belt (leaving a couple inches of slack as a just in case I needed to make adjustments) and test fitted it. Once I determined that I took all the slack out I crimped down the metal pieces and hooked that side in.
This again was simple and could be done at home quickly. The total for shipping and 2 meters of this cord was $7.40.
This cord is a about 30% narrower than the original cord and does not have nylon on the teeth part. So far I have made several cuts with no issues, other than that some of the cartridges still do not read. But for a free machine, it works!!!!
Plus I still have enough belt for one more repair….
This page continues to have a steady stream of traffic and comments, thank you all for posting your problems and solutions alike!
Although I haven't done much trading in machines and parts, I've gotten a lot of requests for a few in particular, like the knobs and the plastic hinged arm from the cutter carriage, which I've mostly been unable to help with.
In order to try and help with this, whenever I find them out, I'll put up "known compatible" replacement part number/source information. I'm sure that the toothed belt, USB port, voltage regulator, and carriage end-stop button are in this category.
Secondly, if you have a broken machine, if you're not near Austin, Texas, I probably can't fix it for you.
But, if you need a specific part, or if you have already replaced your machine and want to get rid of the old one, send me a note and I'll see if I can help.
Offers of free or cheap donor machines and parts are always welcome. I don't do this as a business or to profit in any real way.
Unfortunately I only can deal with the "old" Personal, Create, Cake, and Expression machines. The Imagine and later generation machines like Mini and Expression2 are completely different and I cannot help aside from encouraging people to post any repair tips they may have about these.
In other news..
Last night I managed to ruin an Expression that I was trying to fix, one of the last in my "broken" pile 🙁 My two already-working Expressions are currently out on loan and I needed one so I decided to see if I could finally get this one going.
The 5v regulator was fried, and got very hot quickly and smelled bad after turning the power on. I'm not sure why, but I did find (and fix) a pinched (and broken) ribbon cable for the display - perhaps it caused a short, causing the other issue. We'll never know.
Anyhow I misunderstood the part number when ordering and replaced it with an adjustable regulator of the same part number, which only output 1.2v since it wasn't configured properly. In trying to figure out my mistake, my multimeter probe shorted two pins together which sent 32v (or nearly) through everything it was connected to 🙁
The CPU now has a nice bulge in the middle and just gets hot instead of working at 5v. I considered trying to replace it, but the chip alone is about $13 and who knows what else is fried. 🙁 The good news is I can take it apart and find new homes for the surviving (practically brand new and unused-looking) remains.
Moral of the story: the PROPER 5v voltage regulator for the Expression and Create (probably the Personal as well) is the LM2576−5 (5v fixed) and NOT the adjustable one.
At long last, I took a photo of the repairs for the "broken inner-layer traces" issue.
First photo shows the front of the board. The broken traces connect one of the inductor leads (circled) to the 5v voltage regulator and to the large capacitor below it.
This next photo shows where the jumpers were placed. Your mileage may vary, but this got mine working.
2) Another Create model would power up and boot fully, but the display would be either blank or show only a single line of pixels. Swapping out the display for another known-good one did not have any effect. This turned out to be a broken +5V power supply line to the OLED display connector. (pin 2, counting from the end with the red stripe). I repaired this one by adding a jumper over to the +5V power supply line on the keyboard connector an inch away.
One expression, when you pushed the power button, would light up, but instead of booting would just beep three times and halt. This turned out to be simply a disconnected keyboard cable. The fix was simply to plug the cable back in to the motherboard.
Broken Limit Switch wires
Two different machines had this problem - they would start up okay, but when the carriage would slide all the way to right, it would crash at the end and make a horrible grinding noise. This indicates a problem with the button located in the right-side hidey-hole or the wires leading to it.
Upon removing the right-side cover, I discovered in one case that the pair of wires from the limit switch had been severed by the sharp edge of the metal motor bracket inside. Repairing the wires solved the problem. In another case, one of the wires had simply fallen off the switch, and I was able to just plug it back in.
Broken Solenoid wire
One Create would operate normally, except the cutting blade would not go up and down at all. A number of people have reported issues with very low cutting pressure as well.
Often, this is caused by broken or partly-broken solder joints at the top of the cutter carriage where the power wires attach. There (usually) is a blob of hot-glue on there to prevent the problem, but it doesn't always work.
If you have this kind of problem, remove the cover from the carriage and try poking or gently tugging on those wires and they may just fall right off. You should be able to remove the old hot glue by just peeling it off gently.
Space is pretty tight, but if you're careful you should be able to either resolder them directly or add a little piece of wire to extend them enough to re-attach. Putting a new blob of hot glue on top is also recommended.
This problem seems to be one of the most common, and the easiest to fix as well. The machine seems to operate normally, except that the blade drags in some places, cutting where it shouldn't, and hangs up in some places, not cutting where it should. Normally, the blade holder should move smoothly up and down. You should be able to push it down with no friction detected, and when released, it should move smoothly and freely back upwards.
In some cases, the lower of the two leaf springs in the cutter solenoid mechanism can get bent, causing a slight misalignment, which creates friction that causes the observed "dragging" behavior.
The fix for this is about the simplest of all: remove 3 screws covering the cutter carriage, and simply pinch with your fingers the upper and lower leaf springs together at the right hinge point. (Where the red circles are in the photo below). This should straighten the bent lower leaf spring and free up the movement.
The power brick is an 18v 2.5A switching power supply with a pretty standard cord end, so you could probably find something compatible, but you can get the real thing from PC itself for $9.99.
If you're looking for used parts, there used to be a few places to try, but they seem to have quit. I personally have a small number of bits and pieces for the Personal, Create, and Expression - but nothing for Expression 2, Mini, Imagine, or other later devices.
I'm not 100% certain, but the US Cutter Refine carriage looks identical from the photo.
I have several machines that I have not yet repaired.
One is a Personal model that will often fail to boot, and show only dark squares on the LCD screen. It was described this way to me before I got it, worked fine upon receipt, but then stopped working again soon after. There must be a bad connection somewhere, because just picking it up and putting it down again will sometimes fix it.
Another is an Expression that, when powered on, the power light comes on, but nothing else, and the 5V regulator starts to get very hot. (see the 3/27/14 update where I toasted this one trying to fix it- the regulator WAS the problem).
