Layer issues

by mrhers2

Hi! I have an R1+ and my picture shows the problems I'm having. It's almost as if random layers are missing. I'm printing with Hatchbox 1.75 (does it with all the colors I currently have: grey, blue, white, red) at 200C, 0.3 layer height, speed of 60 across the board (perimeter, infill, etc.). I tried clearing out any jams in the extruder and it goes right back to doing this. Is this a temperature problem? Do I need to go higher or lower temps?

Failing Bed Adhesion

by datnewsome

I know that this is a common problem on this form, but this is a special case.

Background Information: My printer is only about 2 months old and only has 70 hours on it. I use hairspray for bed adhesion. I use matter-control as my interface and I use the default settings. 95% of my prints are using "Medium" quality and they turn out great.

Problem: My problem is that no matter how much I adjust the settings or how much hairspray and glue I use, whenever my printer is set to "High" quality, around 12-15 minutes into the print some part of the print starts to come off of the bed. The weird part of this is that it doesn't matter if it is a big print or a small print, they will both fail.

Anyone have any ideas for this? Thank you all for your time.

Does anybody know if a Ramps 1.6 & TFT35 screen could be used?

by BrooklynBay

I would like to know if a Ramps 1.6 board could be used to upgrade from a Ramps 1.4 in the Robo 3D R1. Here's a link: https://www.ebay.com/itm/273027430202. The next question is about using a TFT35 touch screen. Here's a link: https://www.ebay.com/itm/272993734745. The seller has no idea about any of these things. They just sell the products, and don't have any technical information about them. Do I need to edit the firmware or are these things plug & play?

According to several listings with the TFT28 & TFT32, it says that they don't require firmware modifications if they work with the Ramps 1.4 board. I couldn't find any information about the TFT35. Those smaller screens list several features such as low filament pause, power outage print recovery, an option to connect to a WIFI board, customized screen icons, etc.

Cooling fan shroud Robo r1 plus

by 3dprintstuff

Hi I have a new Robo r1 plus with the hexagon hot end. I have been printing a lot of flat things that come out perfect, but now I am trying to print statue things, like this bunny I found https://www.myminifactory.com/object/3d-print-spring-bunny-60081 and the little bit of overhang on the bottom of the head always looks partially melted and not very round. I have rotated the part so the head faces the fan, it seemed to helped, but you can still see deformities below the head. I am sure it is the part cooling fan, since the fan is not being directed at the part, it just kinda blows down on the bed. I have printed about a half a dozen different fan shrouds that I have found, I like the one that just snaps over the X carriage, but they all sit below my nozzle. ( I am trying to put the shroud in the rear of my printer). Is there a fan shroud for the Robo R1 plus that someone has made that will go on my printer, I am not very good with modeling stuff, I tried fusion 360, but it is all confusing to me. I see a lot of them for the E3d hot end, but I just got my printer and the stock hot end seems to work fine. Could someone please direct me to a shroud that will not sit below my nozzle, or will I have to learn how to put this E3d nozzle on and the dual fan shroud setup.
