[quote=“VenHeelun”]Does anyone ordered parts from 123-3d.nl ?
You can buy everything in one order so you don’t have to look at so much differend places.
I want to know if the quality of the stuf they have is good.
Also you don’t need a creditcard witch i don’t have.[/quote]

Do you own that website? Nobody asked about a website to buy parts and here you go posting it in this topic.

Sorry that my question does make you feel attacked by me. That was not my intention of cause.
I don’t own the site. I realy just want to know if the stuf they sell is worth my money.
I never bought something there but i am thinking about it.
In earlyer post people asked where they could buy some parts for there printer and they got a respond with links of ebay or other stores they could buy the parts from.
I realy think that it is not very different as what i’m doing now.

[quote=“fitchie”]Another update: white cable loom.

This upgrade is only a visual one because I didn’t like the multicolour flat cable.

The original connectors were dismantled and reused to solder the new wiring.
Spiraflex was used to secure the cable harness to the frame.

In additional small heatsinks were glued with epoxy to the stepper motor drivers.

Hi, that looks awesome. I’m currently running x-axis upgrade, 24v bed, E3dV6, direct drive 1.75mm extruder and some other mods. like tensioner on the x axis belt.
I would LOVE to replace my wiring with something nice and clean like you have!!!

  • What type of wire is it? insulation type? gauge?
  • Do you just use that wrap to keep all together along the frame AND where it moves for the x and y axis? I didn’t know how it “tracked”/ran with the x and y movements.

Thanks!

Good quality, very quick, and good prices!
And I don’t own the site either.

I’ve ordered there. The first shipment of filaments were shipped right back. Very bad. Good service though, with my approval they shipped a different brand (their house brand) and that filament is much better. Still not the best filament there is. But it works. The most problems with filaments I had are with the color white, all brands.

Thank you for a more friendly answer.
So the service is okay. That’s good to know. Filament i can buy localy in a 3d-printing shop. They have a lot of choice. I mean more hardware related components such as wire rods, couplings and belts etc.

    [/quote]Hi Meximelt,

I used this wire:
[ul]PRO POWER MCTR 241607 WHT
24 AWG, 0.2 mm², 300 V
[/ul]

Ordered at Farnell:
be.farnell.com/pro-power/mctr-24 … dp/1177498

The ‘spiraflex’ is used to keep all the wiring in a loom and to guide it along the alu frames. But the connection to the X/Y-platform is done by light gray ribbon cable.

Please see picture below:

Fitchie just wandering are you still using the same settings as page one or have they altered now if you could update would be good thank you


#189

Good question!


#190

Hi Djwardstar,

For quite some time I switched to Simplify3D. In Simplify3D you can tweak numerous settings: the better you understand what you are adjusting, the superior the printed parts.

Most important settings:

[ul]filament: 1,75 mm
layer height: 0,1 mm
nozzle diameter: 0,25 mm
multiplier: 0,9
nozzle temp: 190 °C
heated bed: 50 °C[/ul]

Other settings as follows:


#191

Thank you


#192

[quote=“fitchie”]Thanks guys you for your constructive feedback !

Below you’ll find the Slic3r settings as used for the high precision prints.
Note that the device is printing at very low speed.

[/quote]

Hi Fitchie,

I am sorry if this is redundant,
but do you have current slic3r settings you like for your 8200?
I had to get another printer in the meantime to keep moving along because I melted my ribbon cable to the bed (in 24v upgrade and also rubbing along underside of bed carriage).
It’s a different one completely, but I’ve come to like slic3r alot better now than Simplify3d as it was accelerating too quickly with that!

For the wiring, do you still have the ribbon cable setup in yours? What kind/brand did you use and did you just use more “pairs” to get the heat to the bed???

Thanks!


#193

Sorry to say but I use Simplify3D since a long time, so I’m not able to provide you any other Slic3r settings than posted before.
Simplify3D is accelerating too quickly? You can easily adjust the speed settings in Process Settings > Other > Speed.

That’s correct. Actually I do not not the brand of the flatcable, I cut it off from an old centronics printer lead. For the powered connections, 4 wires are twisted together.

OK Got it!
So under Speed - I thought it only had mm/sec or whatever. The machine itself is literally Accelerating too quickly from place to place printing at speeds I use on another machine. It’s on infill, perimeters, etc. I’ll have to play around with again!
Do you still like simplify 3d over all of the others? I’d love to get back to using just that since I use for my other printer! Hope they have a new ver / updates coming out soon to look forward to as well!

For the response on the flat cable, I assumed that might be the case :slight_smile:
So are you still using the flat cable to send bed power, but using more pairs or something? I’m sure I can sacrifice some SCSI or IDE cables :slight_smile:

I printed the cable chain on my other machine and works awesome! Can’t wait to get up and running again!!!

Let me know!
Thanks again in advance!
Have a great day!


#195

Without any doubt. :slight_smile:
In my opinion Simplify3D performs much better than all the other (freeware) tools.

Correct! I use 2 x 4 wires to power the heated bed and 2 x 3 wires to power the extruder.


#196

Can you tell me how many metres of the white cable did you require to rewire the printer


#197

I know this question is not directed at me, but I did the same rewiring on my printer. I didn’t keep track of the total length used, but a quick estimate is that you need about 1 meter (or less) per run of wire. Each motor needs 4 lines, each thermistor and each limit switch need 2 lines, and each heater needs 2 lines of heavy gauge wire. For a single extruder machine with a heated bed, you would need about:

4 motors x 4 wires: 16m
3 limit switches x 2 wires: 6m
2 thermistors x 2 wires: 4m

2 heaters x 2 wires: 4m **

So, roughly 26 meters of light wire and 4m of heavy wire. Most runs will be shorter than this; a few may be longer.

Thanks for answering !

Thank you again, I ordered a stranded hook-up pre-tinned wire. That should save some time there alone. I cut ALL of the wiring out of my setup. I was sick of the crappy ribbon cables and colors all over the place. How did you track the pins from motors say back to the controller w/o errors? Any hints/tricks? Thanks!


#200

I did use a black and red permanent marker to put dots on each wire.

Example:

[ul]heater cartride : .
thermistor : …
extruder motor red wire : …
extruder motor black wire : [color=#FF0000].[/color]
extruder motor green wire : [color=#FF0000]…[/color]
extruder motor blue wire : [color=#FF0000]…[/color][/ul]
