Issue with 4040 Pro CNC I contacted Sainsmart about a problem that I was having with my 4040 Pro CNC. They responded backed to me quickly and requested some additional information. Upon the receipt of the information from me, they immediately sent me an updated part that has seemed to completely solve my problem! I was very impressed with the responsiveness of their communications and their actions to solve my problem. Thanks again!!

Really fast and adequate assistance Really fast response after request for help. They quickly offered the right solution and when the implementation failed through external factors, they immediately took action and solved the issue in a 2nd attempt. I'm a happy customer.

4 year user I’ve used Sainsmart products for 4 years now and stay with them for their customer service. I run my machines around the clock and they are always quick to help me get new and replacement parts that I need.

High quality Sainsmart makes high quality CNC machines for a variety of applications and their customer service is friendly and timely.

It is so nice to deal with a company… It is so nice to deal with a company with Customer Service. I purchased a 3018 prover last year. I purchased the upgrade kit to a 3040. When I was installing the upgrade, I stripped out the set screws for the coupling between the motor and the lead screw. I went to look for the replacement parts but could not find them. I contacted CS and they went above and beyond what I expected. They sent me the part at no charge and in a timely manner. They also checked on how my experience was and if everything was satisfactory. Again, it is so nice and refreshing to deal with a company that cares about their customers.
