I have a 2nd thermistor on the heatsink itself and it reads 100deg C.
Hm... My heatsink is about 45C, I think. Because I can easily touch it by hand and it's definitely colder than heat-bed @ 60C. And I do not have fan shroud (I use stock mount way).

Yesterday night I printed this fish, all is done pretty well, I was even able to separate the links with not much of force applied.
I like the design and I've printed mine instance.
It's moving absolutely freely (as on video) just after I removed it from the bed. No need cleaning or any force.

The only thing that annoys me is the inconsistency of the layers. Please see the attachments. I'm sure it's something mechanical and I mostly suspect my push rods which are the original ones, but grinded (maybe not enough). Though the whole thing was in the center and the length is around 60mm. I would definitely accuse the push rods if I had a slight offset on just one layer, but they

Hi guys,
Does anybody use Simplify3D? After watching this I thought worth trying it out, but unfortunately they do not provide trial version, one should trust them and just buy.
Actually, they have Try'n'Buy version. But you have to pay $149 first. They just promise to do full refund in 2 weeks if you do not like the program.

Yes, rafts from Cura gives better bottom layer than from Slic3r. But I rarely use rafts, I prefer brims If model has small bottom.
Also, I never faced with infill problems in Slic3r (as in video above). Even more, I have to add more bottom/top layers in Cura, because sometimes Cura fails to close top without gaps. Slic3r gives more solid bottom/top infill for me.
And, yes, Slic3r is slowest slice

I print with PLA at 200-215 C (depends on object fan is on or not). Have just a minor stringing (most of them when slicer forget to do retracts where it should).
My print speeds are:
60mm/s for perimeters,
42mm/s for external perimeter,
90mm/s for infill,
300mm/s for idle moves.
When I used 1m bowden tube I set 8mm retract length at 50mm/s speed. Now I halved the length of the tube (by mo

Is it worth connecting it directly to 12v or it's important to leave it on the RAMPS output so it can pwm the speed? How the fan behaves for you guys?

Hi Levon. Welcome to our community.
This question, actually, was answered a couple of times in this thread, but I can repeat. It's better if hot-end fan is directly connected to 12V (i.e. to PSU) and constantly operates all the t

It is safe to connect the bed to the PSU directly.
Pray tell that if the BED is connected to the PSU Directly how on earth is the temperature controlled?
Of course not for a long time or printing. Just for testing it's fine. See if the led is on, if it gets hot, and of there is no smoke or sprinklers and fire alarms going off.

SIntron has sent me this: is this how you guys hooked it up? I notice the fan being connected on a second hot end position and the power supply being hooked up double. How did you guys do it? Did you do double power supply hook up and fan on the second hot end connection or single power supply hook up and the fan on the board as is shown in the manual (at the spot just behind the b

Noitome, my congratulations.
When you switch heating bed on, one of LEDs located near to bed connector (near mosfet) will light up. So, check if it lights up. If it does not, check the correctness of outputs specification in firmware. If you took firmwares from this thread they should be configured properly.

So I'll uninstall pronterface then.
You absolutely do not need to uninstall it. Just make sure Pronterface is not connected when you are uploading firmware. It even can be running (but disconnected) when you uploading firmware from Arduino IDE.
As for working firmwares, you can find them attached to one of my posts on previous page of this thread.

Plastic parts on Sintron's kit are not strong and durable at all. In my printer I used only 3 original plastic parts: spool holders, extruder drive mount bracket and hot-end mount. Hot end mount was cracked into 2 halves about a month ago. And today I noticed that extruder bracket is also broken, despite on the fact that there is no force at all applying on it during printing.

Hello GrAndAG (or anyone else):
What E-steps value are you guys using?
Currently, I have it as 110:
#define DEFAULT_AXIS_STEPS_PER_UNIT {79, 79, 79, 110}
But, I'm thinking that might be too high, and it's trying to force too much filament through the nozzle, than the nozzle can handle. So, suddenly midway thru the print, I see that the extrusion stops (especially on long prints). I thi

Ok, I'm not an electronics engineer, I have just basic understandings from school I graduated an ages ago. But I would like to understand how endstop works actually.
So, assuming the schematics above is correct (wires are colored (on endstop end) as: red - VCC (+), black - GND and yellow - signal).
The cases:

DRTak,
RAMPS uses 1-3 scheme (in your classification) for endstop wiring. The 4th wire (red in original cable) is used to light up the indicator LED on endstop PCB, and generally can be not wired without affecting endstop functionality.
The schematics of endstop (inputs numbering on the scheme is reversed in comparison with your post above):
Maybe for Duet all 3 wires have to be connected fo

I never had a problem with homing. But I'm still on Sintron's RAMPS and Marlin. Looked in the settings and discovered that the default initial homing speed (when all carriages move up together) in Marlin is set to 8313.6mm/min (odd number, it's 1.732*80*60), then carriages individually do first touch on speed 4800 (80*60), and final touch speed is 1/10th of previous (480, or 80*60/10).

Hmm... Tried both 1.1.7 and 1.2.9. And could not find any significant differences in printing results. Both of them produce good g-code.
Do you mind posting a dump of the "full" Slic3r config from your 1.1.7 setup?
I would like to compare a few things with what I have.
Much appreciated.

I've never blowing to my RAMP and it's still ok. Yes, I know, it's not capable to provide enough current for heated bed, I checked it - on full ratio (255) the polyfuse gets hot and just slowly stops working after a while. With 100/255 PWM it works without any issue, but temperature can reach 65C only. So, I wired the bed through Solid State Relay and my RAMPS is absolutely cold, heat-sinks on st

If I need to connect the second fan, where does it go on the RAMPS board? I do not see a second fan port. I'm think, since the heat-sink fan runs all the time, I need to connect it to the spare +V and GND on the Power-supply directly, and connect the object-fan to the RAMPS fan terminals. That way, I can control it via firmware. Basically, I do not want the object-fan to run for the firs

Just a quick question to those of you using the Duet board: Did you change the 'DRIVE_STEPS_PER_UNIT' setting in 'Platform.h' according to the setting in the Marlin Firmware? Is there something else that needs to be adjusted in 'Platform.h' or 'Configuration.h'?
I do not have Duet board. But I see the line in config.g which does that:

... However there is no ROUND bed paramenter?
No, 1.1.7 does not have parameter to switch shape of bed.
But it's not needed usually. In many firmwares (i.e. in Marlin, which is default for Sintron's printer) the printing area is rectangular/square. Even for delta printers. So I prefer to see square bed in slicers to match printing area.

As was mentioned in one of the earlier pages on this thread, try using Slic3r 1.1.7 (if you are not already using it). Initially after my printer build, I happened to download the latest 1.2.9 version, and I had all sorts of issues, with my prints. That lead me on the wrong track, trying to find issues with the printer (like extrusion parameters and stuff). But the root-cause turned out

The customized design can be downloaded at:
However, there was one problem, the customized STL that the Thingiverse customizer spit out, did not have any fan-mount holes. So, in the interest of time, I just drilled the 4 holes in with my dremel.
The holes are absent because you forgot to reduce fan-mount holes spacing. In your instance the parameters say:

On the E3D v5 vs V6 clone debate for the fan shroud... it seems like its neither.
My sintron clone has a heatsink of 18,6mm diameter. The V6 has 22 mm, the V5 has a whooping 25mm heatsink.
so... not a single heatsink on thingiverse will fit this clone it seem, and i'm afraid that i'm far from skilled enough to design my own.

I have faced with similar problem too. In my case the SDcard works overall.
But...
If printer is switched on while SDcard is in the slot - it works: SDcard is visible and can be used.
If I insert the card into powered printer, I see message "Card inserted", but menu claims that "No SD card" and Pronterfece printed "echo: SD init fail" in the console. If after that I send "M21" (Init SDcard) com
