My first laser engraver!

So I finally caved and bought a Laser Engraver during their holiday sale, and it just got here. Setting it up was actually easier than I thought it would be, which was a relief. I've only done a few test runs on some scrap wood, but the results look really clean. I was a bit worried about getting started with something like this, but the online guides were pretty helpful. Shipping took about 5 days to reach Denver, which was totally fine. Definitely excited to try some bigger projects this weekend.

Good router, slow support

I bought a Genmitsu CNC Router a few weeks ago and it's been working pretty well for my projects. The build quality feels solid, especially for the price point. Assembly took a bit longer than I expected from the instructions, but I got it done. My only real gripe was when I had a question about the software settings; customer service took about three days to get back to me, which felt a little slow. Overall, a decent value if you're patient.

Filament arrived fast

Ordered PLA Filament. It shipped quickly. Quality seems good. No issues printing with it yet. Happy with the purchase.

Consistent quality, as usual

This isn't my first order from SainSmart. I needed some more End Mills for my CNC router and decided to order from them again. The quality was consistent with what I've received before. They always pack items well, and shipping is reliable, usually getting to me within a week. I keep coming back because their parts are dependable for my projects. No complaints this time either.

Decent deal for a beginner

I was looking to get into 3D printing without spending a fortune, and found a good deal on an FDM 3D Printer here. It wasn't the cheapest option out there, but with the bundle offer they had, it felt like I was getting a lot for my money. I also grabbed some PETG Filament since it was discounted with the printer. So far, the prints have been consistent, which is great for a beginner like me. I'm definitely satisfied with the overall value I got.

How long does shipping usually take from SainSmart? I'm in California and want to get a project going soon.

B Ben Reyes 2 months ago

For California, usually pretty quick, like 3-5 business days from my experience. They ship from within the US for most stuff.

I ordered some filament last month, got it in like 4 days to Socal. Think it depends on what you order and if it's in stock at the closest warehouse, but usually not bad.

Can I use a student discount AND a newsletter signup code on the same order? Trying to save as much as possible on a new 3D printer.

A Amber M. 2 months ago

Nah, pretty sure it's just one code per order. Tried that once with a holiday code and my student one, only one applied at checkout.

G Gwen Vargas 2 months ago

They usually only let you use one discount code. Sometimes bundles have automatic discounts though, so if you're getting a printer + filament, that might be a better deal than trying to stack codes.

Hey, thinking about grabbing one of their Genmitsu CNCs. Do they ever have any decent sales on those, or should I just bite the bullet now?

B Ben V. 3 months ago

Yeah, totally. I got my 3018 Pro during a Black Friday deal last year, saved like $50. They definitely do sales for the big holidays.

They often have bundle deals too, like with bits or an enclosure. Keep an eye out around Prime Day or Cyber Monday, that's when I see the bigger discounts, sometimes up to $100 off on the pricier ones.

Is SainSmart legit? Never heard of them before but their Genmitsu CNC looks like a good starter machine compared to something like a Shapeoko.

C Cleo Marsh 2 months ago

Totally legit. I've bought a few things from them over the years, never had an issue. Their Genmitsu stuff is super popular for beginners.

N Nick 2 months ago

Yeah, they're good for getting into CNC or laser stuff without breaking the bank like a Shapeoko or X-Carve would. Support is decent too if you hit a snag with assembly.

Thinking of getting one of their laser engravers, but kinda worried about returns if it's not what I expect. How's their return policy for the bigger items like that?

D Daisy Reyes 3 months ago

I returned a faulty module once, it was pretty straightforward. You just gotta get an RMA from their support and ship it back, usually within 30 days. Read their policy for specifics on bigger stuff though, sometimes there are restocking fees if it's not defective.

Yeah returns were easy, did it last month for an enclosure that didn't fit my setup. Just make sure you keep all the original packaging, makes it way smoother.
