Does anyone have suggestion for cooling the three stepper motors and the RAMP board? Seems to get pretty off after an hour of printing, about 140 degree F. I think a few small fans properly mounted underneath and paralleled onto D9 should do the trick.

I have the LCD and it was an extra add-on. There are some functions that can be change and controlled directly, and with the SD mounted on the left.
I did see rubberband somewhere and also heard that changing the pulleys from 36 to 20 teeth helps to smooth out as well, but harder on the motors.

dnguyenai598,
Can you take a close up picture of the top of it?
I'm wondering if the larger diameter side has any purpose, if facing down, it could alleviate heat transfer to the effector from the hotend. If up, it gives more room around the brass plug. IDK!

That makes sense, but i dont think it's coincidence that the hot end top almost fits into the larger diameter, and watching other videos like this one show just that: http://youtu.be/JrhpLgnzkdw?t=4m51s

Hello everyone! Reporting back with some updates to my printer. I was able to print both ABS and PLA with the kit. I started printing out some upgrades to it. The gold arePLA and the red parts are ABS. Since all I got for a RAMPS mount was a bent acrylic, I printed out an enclosure for it that I will later mount on the side.
For those wondering how the effector is built, you can see in one of the pictures how I built mine. The larger diameter is meant for the hotend to go insinde in. I had to heat up the plastic and pushed the hotend in while it was still soft, because it wasn't big enough for a snug fit.
You're all probably wondering in one of the pictures what I had ghetto rigged to my bed. That was a piece of board with fiberglass insulation sandwiched to get my bed heat up to a good temperature to be able to print ABS. With this contraption, I was only able to get the bed up to 90 degrees. I'm contemplating on changing this whole setup to something more efficient.
I printed the last picture at 0.3 resolution. I'm still using the stock extruder with all these prints. If you're having trouble with slippage while extruding, just play around with the temp and speed settings. That's what I had to do with mine.

What was your temp for ABS and speed setting? For PLA?
I had mine set for PLA=210 and ABS 235-240 at 60mm print speed. Once I go any faster, it starts slipping, that's why I printed out a geared extruder.

Maybe that's where I went wrong. PLA temp was at 190C recommended. ABS was 230C. Where did you get your speed setting. I'm using DEFAULT_AXIS_STEPS_PER_UNIT with {44.44,44.44,44.44,96}, 96 is the setting, not sure if that's correct since I'm using Marlin's.

How long should the rods be then? Thanks for the reporting.Quote

Before I go, I saw a mistake on the instructions manual for the build. I had originally built my effector rods longer, but decided to redo it and follow the instructions. Well, it was wrong! It tells you that the rods should be at 224mm. With this whole kit scaled up, it will only give you an effective build diameter of 150mm. I already ordered some replacement rods so I can maximize the build diameter...the way it's meant to be for a bigger printer.

The rods should be at least 280mm to maximize the whole build diameter. The 224mm is meant for a mini kossel, so I will keep these rods to build a mini.Quote

I was talking about when you slice your .stl file. What you have is just about right for the steps per unit setting. The thermistors are not accurate, that's why I'm printing at a higher temp. When I do the readings with an infrared thermometer, I get 100 degrees on the bed while it's still reading 88 degrees on the LCD.

Having another minor issue: the instructions state to mount the heatbed directly to the acrylic plates using M3 bolts and locknuts, but the heatbead hits the nuts used to mount the arduino.
Maybe some spacers would do the trick, but just wanted to check if I'm doing something wrong here.

It's true that you'd get a shorter build space, but what's the use of having a 180mm diameter if you can't maximize the use of it? 250mm is still better than 224mm rods.Quote

I used 250mm based on the Cerberus design, which used 300mm 2020 extrusions for the base. Longer rods would meant lower height built. Even if you used 224mm, the limitation is toward the Z pillar only; the X and Y pillars have better travel. Too bad the arms can't be adjustable.

I didn't mount the arduino board to the acrylic. It's just sitting on the bottom. However, I was thinking, when my straight acrylic piece comes in, I would raise the built plate a little bit, put it on high tension spring or rubber spacers; thus making the plate adjustable to level it. Then the arduino can be mounted on those two holes. Or better yet, print out an enclosure with a built-in fan to cool the drivers.
Did anyone get anywhere with the auto-leveler servo/switch? Haven't done any work on it since last week when I tried to run PLA through it, and the extruder motor would constantly skip.
