I am upgrading my printer to a full hotbed. My original plan was to connect the AL plate with 600W 120V heater via the ABS rail connectors on the platform rail support. Then I realized I could Drill and tap the 20x40 V rails and install the springs and screws there. Has anyone done that? Does anyone see an issue with doing that?by ruggb - General
the variations of the CBOT are the TripleBOT (like mine, but my belt config is better), and the DBOT. I think some parts of the DBOT are a little overkill. There are also modded parts that can be used on any, but again, things like those huge bottom braces are really way over the top. All of the docs you need are posted on Openbuilds. Because there are so many pages Carl moved it to Google+, whicby ruggb - General

I built a coreXY, CBOT, designed by Carl Fenick and posted on openbuilds. I was also looking to replace a 2up, which was a piece of garbage that I had somehow figured out how to modify it well enough to print parts for a new printer. I stumbled upon Carl's design and immediately fill in love with it. Apparently, so did a lot of other people as shown by the size of his forum. He has moved it to Goby ruggb - General
Thanks -- It would seem like the expansion would be mitigated by oversized holes in the bed. IE, if the screw is 5mm and the hole is 6mm, then the bed can move a total of 1.0mm in X or Y direction. With the spring load, the bed would otherwise be stable in the XY directions during printing, especially since it only moves in Z direction. Since the bed is connected via the screw and spring to a nuby ruggb - General
I am upgrading to a 371x305x6.35mm MIC6 bed with a 300x300mm 120v 600W silicon heater and PET layer. I have a 3 point mount with 5mm screws & springs thru printed blocks to the V rail frame. My concern is the printed blocks and how much heat will be transmitted to them via the screws for a very long print. The screws are mounted 10mm from the long edges, so they are about 30mm from the pad. Tby ruggb - General
that whole structure is symmetrical and all the segments are the same proportion. They can't be all the same size as the diameter changes and there are 120 segments all the way around. I created it at x1000. I printed a single layer (2 perimeters) model - ie without the wall being a 2 sided entity with fill, and it printed perfectly. Slic3r definitely has issues if the model is not to its liking.by ruggb - Slic3r
@o lampe The stl is generated from Sketchup. Why would it affect one section? But then I would expect to see it in the gcode I am using Marlin 1.1.x bug fix build - don't know what is meant by "segmentation free" @dc42 the gcode looks the same on layer 12 and layer 25 so I don't know how it could be the slicer either.

Quoteo_lampe You happen to have bed mesh leveling taper off in 15 layers? I don't use any bed levelingby ruggb - Slic3r
I increased the temp, as upon very close inspection it appeared that the bonding was not very good in that section. It looks a lot better, BUT, 15 layers are still being printed with stepping like head movement which produces horiz lines. At 20 layers it becomes smooth. You can barely see the lines in this pic at about 1 - 2 o'clock. They are more obvious with local vision. At 3,6,9,&12 o'cloby ruggb - Slic3r
on those layers it sounds like the printer is doing strange moves instead of just a smooth rotation. I can actually feel it stepping around what should be a smooth curve. It actually sounds like the printer is following a bad slicer output. I don't hear it on the good layers. When I first printed this with thicker walls I had the same anomaly and these layers were rough - but since it was thickby ruggb - Slic3r

Apparently there are things in a model that seem to divert slic3r's attention. I was getting the cannot close holes with xx points messages. I redid some parts of the model one by one and eventually found the things that were giving me the can't close errors and when I looked at this issue again it seemed to be resolved. I haven't tried a real print yet, but the picture appears to close these holby ruggb - Slic3r
If I use rectilinear as an infill, there are holes in the beginning and end of the fill. not good. I have not noticed this before and I assume it was because I had the extrusion multiplier set at 1. I reduced it to 0.96 to solve a messy first layer and get proper dimensions. But now the print is exactly like the picture. I can count 10 holes either side of the beginning void also.

The support bars were not equally spaced, so being the nit picker I am I decided to make them prettier. Well wouldn't you know, the slicer is back to bridging in one shot across the whole span. Sounds like a Slic3r problem to me. But it looks better and works properly now. update; the number of perimeters also affects this. I went from 4 to 3 and it sectioned it off again.

I have a model that has a platform requiring bridging. I created support for it which also requires bridging. This whole structure is internal to the model and will never be seen once printed so what it looks like is not material as long as the support does its job making the platform bridging sound enough to make what is built on the platform smooth. this is the platform support = 297 The probby ruggb - Slic3r
hey doc, THAT ranks in the top ten best answer I have ever received. Thank you. I was thinking over extrusion but since I can't see it on subsequent layers, I couldn't rationalize it. However, I thought I had that covered. But then I've changed nozzle size since I did that exercise so that may have something to do with it. Since I went to 0.2 layer height, it is hardly noticeable.

1st layer speed 50% or 30 mm/sec it looks good on the first few perimeters than goes nuts. Why wouldn't it start doing it on first perimeter?? Just trying to understand what is happening. I keep reading about 80% but no one says anything about why.by ruggb - CoreXY Machines
This is very obvious on the first layer most recent extrusion. The first few lines don't seem to do it.

@dmould thx. I am not sure why you are seeing that. I have not used OpenScad, but I have it loaded. I will try to open it with that out of curiosity. The problem was that the inside faces of the internal box were reversed. Rather impossible to see in Sketchup the way I had things colored (default). When I reversed the faces, Slic3r cut it the way I intended. At first I punched a hole into the cenby ruggb - Slic3r
Sorry, I thought it was the stl I uploaded. I just picked the wrong file. Let me try again, because after re-reading that I think it isn't right. I am trying to make a part that has one wall = 1mm and the opposite wall = 2mm with the walls infilled but no infill between the walls. I thought Slic3r would do that with this model, but it wants to infill the whole thing.by ruggb - Slic3r

I was printing this, when at the beginning of the wall section the printer abruptly shifted the X&Y position about 1.5mm. Then, as it printed approx 10 more layers it gradually moved back to the correct position. The model did not move, the bed did not move, the belts are tight on the XY platform, power is supplied from a UPS, Slic3r shows the correct view without any jogs.

Well, the stl is solid. Noeither Sketchup or Slic3r has a problem with it. I removed all the inside structure and the slice was exactly the same in time and material for both models. Did anyone try slicing the model and looking at the result? If not, why did I post it?by ruggb - Slic3r
is it possible to print a hollow cube within a hollow cube? IE, Build a 100mm cube with a 5mm walls, then enclose it in a 200mm cube with 5mm walls. One side would be common to both cubes so there is no support required. Slic3r wants to interpret the space between the cubes and the inside of the internal cube as fill space and only print 1 cube with fill. any ideas how to make Slic3r see what Iby ruggb - Slic3r
IMHO - and I know little to nothing about all the physics involved: After reading this, my thought is that is requires programming a physic into Marlin. This implementation seems to be based on monitoring the plastic temp, which is near impossible, then adjusting against the wishes of the PID, creating conflict. It seems to me the function would be better implemented based on speed and better suby ruggb - Firmware - experimental, borrowed, and future
