CNC Router Drawing Robot Kit Writer XYZ Plotter iDraw Hand Writing Robot Kit Open Source for Maker/Geek, Working Area A4

I found set-up was very easy. Had a couple of "glitches" at first with my paper but put tape down so that I knew where the paper was to go each time and this helped a lot. Machine will occasionally stop working but this may be because I'm using it so much. I just close down the program and open up again and I'm good to go!!!

Coming from 3d printing and building a Voron 2.4, I wasn't expecting much of a learning curve. That wasn't the case but don't let that scare you. The documentation is non existent but the machine runs grbl 1.3a.20210424. The pen moves on the Z axis just like the print head on a 3d printer but it is inverted. Moving toward the bed is moving in the positive direction. I think some machines use the spindle commands to control the pen but that is not the case with this machine. The Z axis is spring loaded meaning that you can control the amount of pressure on the pen by pushing past 0. This also means that need to disable the step idle timeout with $1=255. Without that the spring will pull the pen back up as soon as the move finishes.

Excelente producto

El producto llegó bien empaquetado y protegido. Realmente fue muy fácil instalar el brazo y las conexiones. Ahora solo hay que ponerse a estudiar los tutoriales para sacarle provecho al software. Desde hace 5 años tengo la axi draw machine, y ésta de bachin me dejó mucho más satisfecha.

UPDATE: It stopped turning on after about a week of use. Checked all the connections. They were kind enough to send me a replacement. The replacement was DOA. I've returned both for a full refund. Super easy to assemble. I wanted a robotic writer for my Christmas cards and letters to clients. This is super easy to assemble. The software is about 70% there. The drawings come out like a dot matrix printer. It just draws it horizontally line by line. Takes for ever. Not sure how to get it to plot out a drawing so it doesn't take an eternity to make a simple drawing. I suppose a CAD engineer can figure this out. The "handwriting" fonts it comes with are not good. It looks like it was done by a 5th grader. The software/website doesn't allow you to upload your handwriting. Perhaps it's a feature in future versions. All the documentation says to go to the company website and download the handwriting app for android. When you try, it doesn't exist - at least the app doesn't exist. Not on their website or on Playstore. So don't expect to see your handwriting or signature on paper with this. This product's documentation is poor. About what you expect for a Chinese company that is too cheap to hire westerners to write the instructions. You do have to calibrate the device to work with each page. Not 100% intuitive. It's taken me some time to figure it out. Being an American, I didn't have a metric ruler in my house. I would suggest you purchase one to help calibrate this device to the exact dimensions of your paper. The youtube instructions are wanting. A forum exists. You can't log in - the "create new user" has been disabled. There is no email or support link. If it doesn't work... too bad.
