SainSmart Genmitsu 3018-PROVer CNC Router Machine with GRBL Offline Control, Limit Switches & Emergency-Stop, XYZ Working Area 300 x 180 x 45mm

The operation and functionality of the machine is really easy to understand. Trying to get the best results is really interesting as there are so many bits and techniques to cutting.
I look forward to diving deeper.

Ich habe mir die Frse gekauft, um kleinere private Projekte zu verwirklichen und den Einstieg in die CNC Bearbeitung zu wagen. Die Verpackung der einzelnen Komponenten war professionell sehr gut und auch der Zusammenbau der Maschine ging fr Laien gut von der Hand. Es ist alles sehr gut Schritt fr Schritt beschrieben. Bei der ersten Inbetriebnahme hatte ich zunchst meine Problemchen, aber ich bin Laie und daher zu vernachlssigen.
Leider fiel nach einem Tag die Steuerung der X-Achse aus und ich kontaktierte zuerst den Support von Amazon, die mich dann an den Support von Tech Maker weiterleiteten. Da mein Englisch nicht das beste ist schrieb ich in Deutsch und schilderte das Problem. Einen Tag spter erhielt ich schon die Antwort und genau 5 Tage nach meinem ersten Kontakt bekam ich ein neues Mainboard per Express Lieferung aus Asien zugeschickt.
Das nenne ich Service, einfach hervorragend.
Die Maschine ist fr Anfnger bestens geeignet und wenn etwas defekt gehen sollte ist der Support von Tech Maker einfach grandios. Kann ich nur weiterempfehlen.

I bought this to learn about CNC and figured this was an economical way to understand how it all fits together. I purchased the 3018 y-axis extension to 3040 and the extension aluminum spoil board. It took a bit of effort to get it all together – be sure to measure diagonally/corner to corner on both sides to ensure the measurements match before tightening everything up. This helps ensure the base is square. If you don’t purchase the y-axis extension then everything is already square.
The instructions for the assembly are complete and the video makes it pretty obvious. All of the cables are nicely labelled and a corresponding label is on the circuit/driver board. It takes a few minutes but none of it is all that difficult. Once fully assembled everything worked as expected.

If you are a Mac user, ignore most of the documentation talking about serial drivers; modern MacOS has the serial drivers built in so there is no need to install them. The Candle software itself does not work so go looking open source package UGS or use one of the web based tools.

After experiencing inconsistent results connecting via USB I found if you turn off the 24V power, connect USB to the computer, connect with UGS, and then turn on the 24 V power things work fine. If you turn on the 24 V power first UGS gets stuck “connecting” but never actually transitions to “idle” which is what you should see when properly connected.

If you are interested in doing more than some basic etching work with wood, be prepared to purchase additional bits. The package includes 12 bits suitable for etching and small tasks but are not much use for making pockets or larger carving tasks. Don’t expect to be able to work with metal to make gears and such, the motor is no where near powerful enough and even a small project would take many hours. Etching of metal may work but cutting metal is unlikely to yield acceptable results.

I was somewhat disappointed once the 3040 extension spoil board was installed because it reduces the z-axis; there isn’t room to use the z probe on top of a 3/4″ piece of wood or room to work with a piece of wood 1″ thick. There is room for the 3/4″ wood however, just that it makes setting the z-axis to zero impossible with the probe. Spread a piece of tin-foil on the top and lay the z-probe upside down on the foil. Connect up the alligator clip to the bit as usual and run the zero commands. Not as convenient as the z probe by itself but it will work. If you go looking, there are some youtube videos explaining how to use the old 3018 side rails and some brackets to raise the z-axis and that’s my next to-do so I can handle thicker pieces of wood or work with 3/4″ stock without having difficulty setting the y-axis zero point.

I had a strange problem with the offline controller. It was showing error code 2 all the time. I contacted support, explaining the problem and within a day a new offline controller was on its way. The replacement worked perfectly. I had a few other minor difficulties but their support was great. Very helpful and provided assistance and advice.

Overall this is a solidly built unit perfect for small projects and learning about CNC.

Fr den Preis gut, einige Verbesserungen waren sehr gut,
1. der not aus ist an einer ungnstigen Position, vorne wre viel besser.
2. die Endabschaltung bei manueller Steuerung muss jedes mal mit lange Enter drcken besttigt werden,
das fhrt bei inigen Programmen zu Fehlermeldungen, die auch dort noch mal besttigt werden
mssen.
eine einfache Abschaltung wre besser.
3. Fr einiges Billiger bekommt man fast die gleiche CNC Frse. Habe mich aber fr diesen Hersteller entschieden.

Assembly was easy and the directions were clear. Overall I’ve had a lot of fun learning CNC with it. Make no mistake, this is a beginner machine, but it does everything I’ve asked so far. I definitely recommend the 20k spindle and the 3040 extension to go with it.

I purchased this machine at the beginning of 2020. Brand new to the cnc world this was a great entry level machine that let me dip my toes into the area for a pretty reasonable price. Some mistakes were made along the way but the machine is pretty forgiving. Two years later the machine was still going strong until there was an accident in the shop which caused me to need some replacement parts due to no fault of the machine. While the parts have been out of stock in the US I have been working with customer support and they have been quite helpful. Overall it this has been a great starter machine.

Tolle kleine CNC fr den Anfang, fr kleine Bastelarbeiten perfekt. Metall oder hnliche harte Materialien wrde ich damit nicht bearbeiten, aber fr Holz und Acrylglas ist es gut geeignet. Mit dem Support habe ich auch gute Erfahrungen gemacht, nach 1.5 Jahren ging der Spindelmotor nicht mehr an, nachdem ich im Betrieb den Hauptschalter ausgeschalten habe. Sofort wurde mir angeboten kostenfrei eine Ersatzplatine zugesendet zu bekommen. Als das Problem dadurch nicht behoben wurde, haben sie mir ebenfalls kostenfrei mehr Teile zugeschickt bis die Maschine wieder funktionierte. Zu erwhnen bleibt, dass sowohl die Anleitung und die Software, als auch der Support komplett auf englisch sind.

I am Registered Partially sighted & it took me a week from the start to Make the spindle move. Love it/

Comes part set up, Trust me if you have never used G codes it is an eye opener. Will take time for you to grasp it, But once you have well all will be good with the World & you can sell this (doesn’t depreciate much) & get the next size up. not like you would expect the tooling that you should use is expensive. & workspace is not very big but i got it to add Designs to my products. loads of really good videos to watch & you would be better off becoming an Amazon Prime member before you buy this Machine, Get free prime delivery & save a bundle on other purchases too
Watch the videos & check it’s complete before you start Building. Top CNC router for Entry Level. You could even up grade it when you feel you want more Get the next motor size up & a metal Motor mount.

I had this product for a year. I used a lot in the beginning and then put it off as I was busy with other projects. After a while, I came back and worked on this machine and something was not working. I contacted the customer service. After a day, Hong from Sainsmart, provides me a list of diagnosis methods. I tried all of them, did not work and sent him the screenshot. The next day, Hong informed me that he was sending me another control board for free as it was covered in the warranty. He also followed up with me when my new control board came and checked if everything is alright. Excellent customer service.

Also, the machine is super easy to assemble and the limit switch on the x,y, and z axis make it very safe. The spindle is pretty powerful and can do some damage and it can also cut some thin aluminum. (You need to go very slow).

The one thing that this machine can improve on is the instruction on the programming side. As a beginner, I spent a lot of time and installed several programs (including freeCad) to start to cut my piece.
At the end, I found the easiest way is to create a simple text file and type the G-Code myself. If there is simple instructions/examples on G-Code like G0, G1 and G2, it will make a big difference to get a beginner started. As beginner, I just want to cut a straight line to test it out, but I found that it was a lot of learning and time using freeCAD other CAD program to do such a simple thing.

I was concerned after reading some negative reviews but when I unpacked it, everything was there and in good condition. My son and I assembled this in about 1 hour. The instructions are very clear. We were impressed by the engineering of the unit and the obvious thought that went into assembling it. After connecting all of the wires, we turned it on and everything worked properly. We connected it to a computer and, after installing the device driver and choosing the proper communication port (that’s important) we were able to run one of the test files included and that worked perfectly. The process might be difficult for a novice, but if you can follow instructions and watch the videos, it’s not too difficult. The only thing we were not prepared for and couldn’t immediately do was set the height of the Z probe because we didn’t have proper calipers on hand. I imagine you could take it into any hardware store and get a measurement if you don’t own calipers.

Aprs plusieurs mois d’utilisation, je suis trs content de cette machine. Je prcise que j’en ai une utilisation assez simple de gravure ou de petites dcoupes. J’apprcie de pouvoir travailler le fichier tranquillement sur mon ordinateur et de le transfrer ensuite sur carte SD (la machine est loigne de l’ordinateur) et d’avoir les commandes de contrle indpendantes pour calibrer, faire le zro et lancer le fichier. Un fichier bien prpar et le rsultat de qualit est au rendez-vous

Produit fonctionne bien avec les fichiers fournis. Attention, la multitude de logiciels pour la conception de pices 3D et leurs transfert en format GCODE sont payants.

For the money this is a very capable machine unfortunately the control board on mine failed, I emailed the seller who got back to me very quickly and after telling them what I had done to ascertain that the control board had failed and that the machine was in warranty they arranged for a new board to be sent to me.
When it arrived it was duly installed and my machine was back up and running again so full marks to Tech Maker.
