I really like this printer
I really like this printer.
I am new to 3D printing. I ordered the Tornado as a Christmas present for myself after reading many reviews and articles about it's value and large build size and it arrived 1/11/19. My Tornado is the Gold colored 2018 version.
After finishing the assembly which was basically adding the Z axis, Y carraige and bed, limit switches and connecting the wiring harnesses it came alive and was printing that night using the supplied SD card. It printed really well to be right out of the box. Since then I have kept it really busy and have several hundred hours on it with only a few problems printing, which are common to all 3D printers such as fails due to poor bed adhesion. I have worked thru those issues.
The Tevo Tornado quick setup guide refers the new user to Facebook and Google for Tornado user groups for help. There is no Tech Support phone number, but you can email them and create a ticket.
I've learned much from those groups, got a lot of suggestions and ideas.
My printer however, has never been able to communicate with my Windows 8.1 desktop for operation and control via a slicer. I could only print via the SD card until I learned of the Raspberry Pi and Octoprint, which gave my desktop computer control. I've tried a different computer and had mine checked out and found it to be working fine. I've read all I can find to try to solve the problem but can't get it worked out. I am no computer technician.
I contacted Tevo's Support site by email and they responded by sending an attachment of a printer driver to try. I couldn't get it to work. After another contact they sent a firmware download attachment which I can't figure how to load without a connection. The printer's control box has the latest hardware and uses Marlin firmware for printer operation. I desire to load a later Marlin firmware that has Filament Change feature but cannot without that USB printer port connection. I've read of other ways to do this but certainly am not fluent in Arduino and code manipulation and am afraid of killing the printer(and voiding the warranty). I can find no one locally familiar with this printer.
In conclusion, I believe Tevo has a very strong product, well designed and made with much quality. What I think would make their printer a far greater printer value would be a technical support department that could be reached by telephone call. I'd be willing to pay for tech support, if I could get it. It appears it's totally up to me to fix this problem, which I don't know how to do.
