Alternatively if you're feeling brave you could disassemble the push fit connector and drill it out the same as the one on the hotend, which would allow you to push the bowden cable all the way through the hole in the extruder until it's almost touching the extruder gear and idler bearing.

What's that part that you used? Can I buy that somewhere?
It's definitely strange. Because I'm printing PLA at 60mm/s for perimeters and 100mm/s for infill without any issue.Quote

I've a strange roll of PLA - more than about 10-15mm/sek printing speed is not possible.. (Volumetric 1,3mm³/sek)..

thanks for the heads-up. I have never noticed the RAMPS to run very hot, but i only heated the heatbed to 60 degrees for PLA. Have not tried ABS yet before i can put stronger fans under my heatbed and i have kapton tape (painters tape probably wont like it if i heat the bed to 90 degrees for an extended amount of time. Anyone tried printing without any type of tape or adhesive on the bed by the way?Quote

Sintron offered me a new PSU. I dint expect that. the service is really incredible for a HK seller. I asked if they could send a 20A version, and they agreed for 10 dollar more.
Good deal, good service. parts quality may not be premium grade (as should have been expected for this price), but i'm still happy i bought this set.
More important is the ammount of power, the RAMPS is eating away from the heatbed.
Inputvoltage 11.97V Output RAMPS for Heatbed 9.46V - RAMPS gets very hot!
I don't want to discuss things with sintron anymore - just try to use a relay for heatbed and a PC-Powersupply (360W on +12V available)
But I have another strange behaviour:
I'm printig PLA with Nozzle 0.4mm
Layerheight 0,2mm
Hotend Temp 215°C (less temperature I won't get stron parts) - Temperature checked is 212°C
I can only achive 15mm/sec - seems much to low for me.... trying more Speed, extrudermotor jumps back - it can't push the Filament faster because it won't melt fast enough...
did the volumetric Speed test - only 1.3mm³/sek - read somewhere it should be over 5mm³/sek
So what are your values?
about the extrusion problem: maybe the current is set too low on the extruder, causing it to skip steps? just guessing, i dont know jack about currents and what the right current would be...
If you tell me how to perform the volumetric test, i will gladly try it and report the results back.

Today I did very first print. It works! Here it is the 1x1x1cm test cube:
[attachment 65181 20151102_232358_crop.jpg]
The bottom layer is a bit junky because the filament was just inserted and the extrusion was not started at very beginning.
But why the corners are round a bit? Is it normal?
And it seems it over-extruded (but I calibrated extruder precisely: 100mm requested - 100mm got).
The settings was: PLA @ 200C, layer 0.3.
[EDIT]
And after the print I got a thin straight solid thread of plastic 20cm long from last printing point to the nozzle. Not enough retraction at the end? Or wrong temperature?
[EDIT2]
How to eliminate plastic threads while head is moving from object to object without printing?

Does anyone happen to have the STLs for the sintron effector and holder/bracket, or can recommend an effector that works with the E3D that sintron provided in their kits? mine was printed with a very badly calibrated printer it seems, and there is a 2 layer difference between left and right, resulting in a slanted hotend (and small gaps in my prints)

That's bad...
I found this one : [www.thingiverse.com]
Looks like that one has the same dimensions as the sintron version

Silly question. Is the power supply suppose to be 110 or 220V. Also, which wire goes to L and N for AC power.
Thanks
Aloha,
if you have to ask such things, it's better to let someone else with experience do that for you.

Thanks for the useful information.
I'm quite capable of building this, I'm just trying to double check my work so I don't fry anything.
Unrelated to my first question: Does it matter what two wires on the hotend.

I seriously don't think he wrote that with an attitude.
That part of the printer you were asking about could be lethal if not done properly.
As I read the question and I suppose he did as well you don't come out as very enlightened on the matter, so he gave a sound advice.
Regarding the hotend - I understand it as you are wondering if the heating element is polarized?
It isn't so it won't mattermatter which wire goes on + or -

Thanks. Yea I wasn't sure if it was polar or not.
As for the power supply, I will be getting a proper power cord (one with a ground) and correct color coadings for load and neutral. I dont understand the intenet behind the one supplied with this kit. I guess I asked the question too vaguely which I can understand why you guys responded the way you did.
Thanks for the help.

I'd suggest that whatever you do, you first do that and check the output using multimeter before connecting to the electronics. Frying this PSU is not so bad. I didn't like it, haven't even tried to check if it works. Frying electronics is a bit more traumatic experience.

Are both Com and V+ (four total) connected to the Ramps? I have seen different diagrams and some show 2 connected while some show all 4.
For some reason the Ramps works (fan blows) but the Arduino doesn't come on. The only way to get the Arduino to turn on is unplugging the probe swtch. Any ideas?
Thanks

Okay I have everything fired up now. Only issue now is going though the checks in Pronterface. All the end stops and probe switch appear to be functiong. When I go to hit the hope button or G28 the X carriage goes down in the opposite direction instead of going towards the end stop. This happens until Y and Z hit their respective stops. Any ideas?
Thanks again.

Just a quick advice to you guys. If you have a leaking hotend, like pla is squeezing from the threads on the hotend, go fix it asap! I had just a littlebit of leaking there and after some prints ( yes, I got it somehow working) I wanted to clean the noozle (again) and stop the leaking there. I just could not screw the noozle or the screw to the head sink out of the hotend. Like it was welded together. Tried it warm an cold... Finally both threads teared off leaving me with a broken printhead and a puls of 200. This kit drives me nuts, seriously.

... from cold to very hot.... just slowly with a torch. No matter what, the screws did not move at all. After the screws broke off I tried to recover it with a "bold extractor", dont know the exact english word. Now where I had nothing to lose I tried even brute force. No chance. Like it was welded together.I gave up when I saw the aluminum breaking from the stretching from the bold extractor.
