Getting Rid of Salmon Skin with 8 Diode Smoothers
UPDATE: As of March 2018, Tevo Tornados are shipping with a new board that is supposed to remove the salmon skin problem. There are a number of printers still in the retail pipeline that do not have the new board, and can be helped with the smoothers.
One of the issues found with the Tevo Tornado, is that it suffers from Salmon Skin when printing. Rui Raptor jumped in and created a terrific video showing us how to fix the issue quickly and easily… use an 8 diode smoother board. You need to confirm that the wires are correct for this to work right, and the video shows how to build the proper wire. He explains why you want to use 8 over 4, giving us examples. If you have a Tornado, this is a pretty simple upgrade that will help the quality of your prints. If you have a Tevo Tornado, this video series is a must watch.
If you want to find out even more about the Tevo Tornado, check out this article.
These smoothers can be obtained at AliExpress, or Amazon-US(3) / Amazon-US (1) / Amazon – UK.
The article is misleading or out of date, as the Tornado has now other drivers, rendering to smoother useless, but the salmon skin is still there though.
There are still a number of units out there, that can use this information. It’s neither misleading or out of date. It may not be relevant for the next gen that is just starting to ship, but it is relevant to the thousands of units that are already in people’s hands.
I have just recived my printer how can i tell if i should fit the smothers
You may have the new board that doesn’t need them. Try printing, and see how it looks. I bought the smoothers, but have not had enough problems to install them. Some people have major problems with salmon skin.
I have installed the 8 diode smoothers (mks makerbot v1). Cable are wired as they should. But when I start up and manually drive the motors the motherboard reboots or just display a grid on the display and nothing works. Is it maybe due to a voltage drop from the diodes? Should I adjust the voltage?
Really need help with this. I need to get it to work….
I’d recommend checking out that Facebook group: https://www.facebook.com/groups/TEVO.Tornado.Owners/ Unfortunately, I never got mine installed before my printer died, and I’m still not sure what is wrong with my Tornado. I would think people in the FB group would have more knowledge than I do. I am more plug and play, and then if it fails, THEN I dig deeper.
