I inquired about the 7.2Nm 3-axis kit several days ago and no response. Has anyone received and installed one of these kits? I would really like to hear some first hand feedback before shellling out $1300

I have contacted both info@dmm-tech.com and sales@dmm-tech.com and no reply from either regarding the 7.2Nm 3-axis kit. I did a google search on their address and it shows an apartment complex in the street level view. I'm not getting a warm-fuzzy.

This is very strange as myself & others have received emails,almost right away,my last was on Saturday , & one of the Zone members who is doing a build has received his Drive package,& is putting it together, he is very happy with it & the service, The owner of DMM has been in business for 15 years

I will have my test drive motor package as soon as the 400w motors are in, but the larger motors are in stock,

I just sent him a email for you, there web page is being redone so there may be something wrong with the email connnection

Thanks for looking into that for me. I sent a third email, this one from my Yahoo account to all three of the addresses above. I'm sure the first two emails went out as I bcc'd the second one to my Yahoo account and it was received. I'll let you know if I hear back from them.

I did receive an email shortly afterward from Hui. Not sure why I didn't receive his email as I had received many others with the same account. Regardless, looking forward to getting these motors.

Update. Hui at DMM-Tech informed me that they will have 300W NEMA 23 AC servos, with absolute optical encoders available in the next couple weeks. I'm in for one.
