I would 100% recommend this machine if you are looking to write letters that look handwritten, whether it be cursive or print. I sometimes do cursive and sometimes print and both look amazing. My thoughts are below:

I bought this machine a year ago and have used it to write a few hundred letters per month on average. It's working just as good and even better since they updated the software to where it writes more efficiently/quickly so the time to write a letter has gotten a little faster. I use the machine for marketing to drive leads to me in the real estate industry to help buy and sell real estate.

I remember before I bought mine, I set up a call with them and we did a zoom call where the representative showed me the machine in action on the call and also showed me the software and assured me it would do the tasks that I was wanting to do for my marketing. Book a call if you are unsure and it solidified it for me that the machine did exactly what I needed it to.

The machine and software settings allow you to write letters that are as authentic as you can get and truly look handwritten. Now, you will have to tweak the software to get it to look exactly how you want and set it up to merge with excel, but it's worth it. They are absolutely great with their customer support if you ever need help. Once you have it set up how you like it, you save the settings so you don’t have to do it again. Then you can tweak it how you want it more easily once you get comfortable with changing all the settings. There will be a learning curve with it but they have helpful videos and of course customer service.

This is the second pen plotter I have owned, and I am thoroughly impressed with the upgrade in quality. The iDraw H SE (A3) feels incredibly solid and the operation is smooth and stable. As the title says, the precision is excellent; it handles complex vector files and fine lines without any issues.

Setting it up was straightforward, and it fits perfectly into my existing Inkscape workflow. If you are looking for a reliable machine that produces consistent, high-quality results, I highly recommend this one. I absolutely love it.

My UUNATEK Writing Robot A3 is pure creative joy packed into a precise little powerhouse. It’s extremely fun to use, surprisingly versatile, and after following a clear tutorial on the UUNATEK website to set up CNCjs on a Raspberry Pi, I now run my iDraw as a fully wireless pen plotter.

I use this machine to create fast, razor-sharp line-art portraits with a Lamy pen, and the speed and accuracy are impressive. For me, this machine feels like a perfect extension of my studio. It translates digital intention into tactile and expressive drawings. A brilliant bridge between my art and ink.

I have been using the iDraw H SE A3 for some time now, and I can say it is a very successful tool for creativity and experimentation. The device turned out to be quite easy to set up. After installing the software, everything works stably. I mainly prepare vector files in Inkscape and then send them to the plotter. The workflow is clear and logical, even for beginners.

The construction feels solid: a metal frame, smooth motion and good line accuracy. The plotter confidently works with different pens and markers, which is convenient for calligraphy, illustration and generative art. I have used it to draw patterns, lettering and educational projects. I especially enjoy watching digital ideas turn into neat drawings on paper. A great choice for artists, designers and techno-art enthusiasts.

P.S. In the photos are my experiments with scratching on rainbow scratch paper.

I gotta say, the software is a bit fiddly. I did need to ask questions in the Facebook group a couple of times until I got everything up and running. It did get improved a bit over the years though.
Now that everything is set up though, basically only need to press start and it pretty much just works. That's just awesome.
Without the black card recognition upgrade, the black envelopes only work when fed one by one, but even that is easier than doing everything completely by hand.
Oh and contacting their team for basically anything via email is really easy and they do their best to help.

I am using the iDraw H SE A3. It is simple and consistent and worked right out of the box! Tech support always answered my emails and the unit is a lot of fun. I use it for generative art programmed through Python. The physical button to pause the drawing mid-stream is very useful for my process. A video is attached here. Also a plus, there were no import fees into the USA.

I needed specialized support, because my Mac computer (Mac Studio) did not connect anymore to the plotter. Support department suggested a zoom meeting and I accepted. The meeting took 2 zoom sessions of about 45 minutes and took place, mind you, in the weekend, saturday and sunday, and at 5 o'clock in the afternoon! Thie problem was solved and this is what I call excellent support, because two employees took the time in their weekend to solve my problem! Further I'm satisfied about the build quality of the machine, the high precision and the lack of noise during plotting. OTOH, the software available for the Mac Studio is a bit peculiar, some parts are still in Chinese, and it is hard to figure out how the various plot options work.

I purchased this plotter to explore algorithmic art and I have found it to a workhorse machine so far. Although I was already familiar with CNC devices like 3D printers and CNC routers before purchasing this plotter, I don't think the minimal setup would present an issue for beginners, learning Inkscape itself is more of a challenge :)

I purchased the iDraw H SE A3 model and am referring to it for all comments below.

The homing accuracy and general smoothness of the design is excellent. After 1000+ hours of use I have found no discernible change or looseness to the frame. I have found the self-homing to be perfectly sufficient for producing multicolour/pen drawing.

The magnetic board for mounting the paper is great, makes loading and unloading quick and easy. Some magnets shaped like pawns on a chessboard are a little more ergonomic to work with and work the couple of dollar they cost.

The pen holder is fine but could be improved, the threaded section through which the screw goes could be deeper to encourage the screw to stay straight and true. Overall pen to pen accuracy is fine, although you will need to work out offsets if you change between pen types or brands.

I am still using the Inkscape plugin for all my designs, although I may move to CNC.js on a RasPI in the near future to separate the plotter from my computer. The plugin works fine, if not a little dated and clunky. Inkscape may be a little arcane to learn but it is incredibly powerful given it is free.

Beyond Inkscape, I have also gotten great value out of DrawingBotV3, Paragraphic and both the Processing/P5.js and Python programming languages, these are the tools the will unlock the true potential of your plotter. There are plenty of great communities out there to garner inspiration from.

Pen wise, I have found value in a large multicoloured pack of Staedtler ballpoint pens (432 or 437 even better!) and some cheap alcohol ink markers. Don't feel like you need to spend big on expensive pens, cheap ballpoints can produce incredible works of art in the right hands. A black 0.8 or 1.2mm fibre fine liner is useful for outlining shapes and providing definition.

Overall a great machine that unlocks a world of creative potential, the pleasure it has provided me far outweighs the initial cost already.

I would definitely consider purchasing from uunatek again should I decide to explore a larger platform one day in the future, but for now the A3 feels like the sweet spot in terms of total drawing time and material costs.

The iDraw H SE is an absolute joy to work with, turning the creative process into a truly mesmerizing experience. While there is definitely a learning curve when it comes to dialing in the initial settings, once you familiarize yourself with the workflow, it becomes a breeze to program and draw. There is something incredibly fun and therapeutic about watching the machine meticulously bring your digital designs to life on paper, stroke by stroke. It is a perfect blend of technical precision and artistic satisfaction that makes every project rewarding.

The product is easy to use. By carefully following the manufacturer's instructions, I was able to install the Inkscape plugin easily. Assembling the plotter is straightforward, but precisely adjusting the baseplate can be tricky. I managed to reduce the unevenness to within +/- 0.1 mm by manually bending the baseplate. I found that if the deviation exceeds this limit, the lifespan of the fine liner pens is significantly shortened because their tips wear down more quickly where the baseplate has a "bump". Therefore, it is recommended to level the plate before using it for the first time.

The plotter is user-friendly, and configuring its operating parameters is simple. At high speeds, the lines may become slightly wavy; however, this issue can be easily resolved by reducing the speed. The device provides a good estimate of the plotting time, making it easier to decide if slower plotting is acceptable.

The home function allows for precise positioning of the pen tips, and you can change the pen several times while working on a drawing. It is very helpful that only select layers can be plotted from the Inkscape drawing.

Overall, I am very satisfied with this product. After carefully setting up the device, one can create highly detailed and precise plots.

This is a great pen plotter for getting into the plotting world. It was fairly easy to setup and runs via Inkscape to print. The plotter is accurate and fits almost any pen there is due to a universal pen clamp. Unfortunately the only issue I had was one of the legs on the plotter was damaged in shipping but not a big deal, plotter is sill fully functional.

is a solid and accessible tool for creative experimentation. My experience using it for generative art, handwriting-style drawings, and custom illustrations has been very positive. The setup with SVG files is straightforward, the machine produces clean, consistent lines. It fits well into a simple digital-to-physical creative workflow. Recommended!

I purchased the iDraw H SE/A3 pen plotter in April 2025 and had it shipped to Europe. Delivery took about one week, and the plotter arrived in a sturdy, well-designed package. The unit was preassembled and ready to use within roughly 15 minutes.

Build quality is very solid and reassuring. The main work surface features a clear grid, and the included magnets are sufficient to hold paper securely in place. Overall, the hardware feels well thought out and robust.

I have been using the plotter with the provided Inkscape extension, so I cannot comment on the Python API. Beyond artistic plotting, I also use it for practical tasks such as labeling envelopes that do not fit into a standard printer, which works smoothly and is very straightforward. The plotter is also precise enough for technical drawings. CAD drawings can be exported as PDFs, imported directly into Inkscape, and plotted without issue, since the geometry is already defined as paths. For optimal text rendering, the embedded PDF fonts should be replaced with single-stroke fonts.

Overall, I am very satisfied with the complete package and can confidently recommend this plotter.

As side notes: the machine does produce noticeable operating noise, so it is not something you would want running during a quiet rest period, and you should allow sufficient vertical clearance for the pen and cable during operation.

I bought this iAuto Pen Plotter Handwriting Machine to help me write thank-you notes and custom letters in bulk, and it has exceeded my expectations. The automatic feeder handles up to ~80 papers and ~30 cards or envelopes at a time, which saves so much time compared to writing everything by hand.

Setup was straightforward, and the machine gives consistently neat, legible results — perfect for professional-looking thank-you letters, invitations, and more. I especially love that it supports common formats like Word, Excel, and SVG, so I can customize messages and fonts easily.

Whether you run a small business or just send a lot of handwritten notes, this machine has been a huge help and well worth the investment!

This machine is very precise, versatile, and user-friendly. As soon as you plug it in, it's ready to make your graphic dreams come true. The assembly screws do require periodic checking, as they tend to loosen in some places due to vibrations, but this only takes a few seconds and doesn't interrupt the satisfying and mesmerizing user experience. It's very versatile and can do many things; the only limit is the artist using it. Shipping arrives very quickly, and our staff will be happy to assist you with everything.
