SainSmartGenmitsu 4040-PRO MAX CNC Router, 710W Trimmer & Linear Rail Driven, Work Area 400 x 400 x 78mm, for Wood Metal Acrylic Cutting Milling, GRBL Control

Edited review:I had a few issues with my router. I emailed the manufacturer and had conversations with them. After explaining my frustration they did whatever it took to make me whole and happy.The router is good quality but does have some quirks. Between the forums and the manufacturer you will learn how to work though any issues.They earned a 5 star from me because of the great customer service. They do care and want their customers to be happy.

Good machine super easy setup and easy to operate it, has good cut quality at a good price. Had some issues with the software but the support was prompt and helpful.

The machine was well packed and the machine itself seems to be well made. I had an issue with the Y axis cabling from the rear profile connecting to the Y axis motors. It appears to me that the cabling within the rear profile is not correct. So, I’m stuck at that point in the assembly and the biggest concern is the support model provided by SainSmart is terrible. I’ve been waiting on some guidance for two days now and if I can’t get this resolved soon, it will be returned. If a resolution is provided, I’ll update this review with additional comments.SainSmart support responded three plus days after support issue was raised. Support told me to reverse the orientation of the rear profile such that the cabling was reversed. While this makes sense to correct the problems with the cabling, additionally, the rubber feet installed in the rear profile will need to be removed and installed on the opposite side not designed to accommodate the feet. This should work but this was an assembly problem from manufacturing and a better solution would be to send a new rear profile with proper cable orientation. It would also be better if SainSmart had a “new install” support process to minimize delays on problems such as these.After several days of working on a variety of problems and several interactions with support, I’ve decided to return the product. The machine keeps throwing alarms and stops operating. Initially the problems began simply starting to home the device, the controls became inoperable and I was able to clear the alarm with the $X grbl command but it always returned to the same type of problem either homing, jogging or running a job. I’m giving up on this machine but I plan to order a SainSmart replacement and try again.

Shipping has some issues but received to late with no damage other than the box. Easy assembly, start up and first use were also easy. YouTube has many videos on this brand of machines if you get stuck. I have had the machine for 6 months or so and still running great. Size is a little small if your looking to do shop shelves or cabinetry. Good for small pieces and those just getting started. Have used everything from easel to freecad to carveco to vectric so any software you decide to use should work fine.

Absolutely love this machineI'm new to the CNC world and after my research. This unit had everything I needed to get startedImprovements I would say the spoilboard needs to be one solid piece instead of two. Also having a grid layout already on it would be a major plus
