Topic: Digital Sundial

I have tried to print this thing a few times with very little success using stock 1.0a with repetir 0.92.  Sliced with slic3r.

http://www.thingiverse.com/thing:1068443

The thin bridges required to make the Second hand work just turned into a bunch of unruly strings.

I can slow the speed down quite a bit, but is retraction settings what I need to work with to take care of all the extra strings?

Re: Digital Sundial

Try printing it with a layer fan. There are several shrouds on Thingiverse you can use.

Re: Digital Sundial

Thanks for the reply.  Do you power your layer fan from the printer itself or externally?

Re: Digital Sundial

I power it from an external 12v supply.

Re: Digital Sundial

Thanks!  Could it be wired up to be controlled by Repetier and G-code?

Re: Digital Sundial

I would imagine so but I'm not sure it would be worth the hassle.
I just turn it on and leave it whenever I need to use it.
There's not really any downside to it being on during parts of a print which don't need it.

Re: Digital Sundial

Yup.  You need a fan.  Frankly, I don't think any FDM printer should be without it.  It makes a HUGE difference.  I made one here using some Filastruder-made marbled filament.

Re: Digital Sundial

That's really exciting, thanks for the tips!  (pun intended).

I will add a fan for sure, but I wonder if the stock Da Vinci head is simply incapable of the resolution required for the sundial.

Solidoodle 4 is quite a bit more functional I would imagine...

Re: Digital Sundial

a fan certainly helps.

and yes you can set up repetier to control your fan with gcode. I flashed my AIO with the settings set to be able to control a layer fan.

if you have the layer fan set to be controlled by repetier you need a separate fan that is always on to cool your heat break.

right from the page where you get the information to flash the printer there is information on how to set this up.

' #define DAVINCI 1 // "1" For DAVINCI 1.0, "2" For DAVINCI 2.0 with 1 FAN, "3" For DAVINCI 2.0 with 2 FANS, 4 For AiO （no scanner) '
0 for not Davinci board (like DUE/RADDS)
1 for DaVinci 1.0 (1Fan, 1 Extruder)
2 for DaVinci 2.0 SF (1Fan, 2 Extruders)
3 for DaVinci 2.0 (2Fans, 2 Extruders)
4 for DaVinci AiO (no scanner)

Support for 1.0A and 2.0A: need to change  #define MODEL 0  to  #define MODEL 1

To repurpose the main Extruder cooling fan to be controlled VIA G-Code instructions M106/M107:
Set REPURPOSE_FAN_TO_COOL_EXTRUSIONS to 1, do not forget to add a fan with power source to cool extruder permanently if you use this option.

Re: Digital Sundial

@scobo

actualy if your printing abs there can be a down side to having the layer fan on all the time. You can warp your print if your layer fan is on all the time with abs.

For pla its recommended to have the fan on all the time for abs not so much.

However a fan helps on those small points or on bridges, and one that can be controlled in g code for the speed is really nice.  so I agree a fan is a must.

Thanks, I looked that up shortly after asking, as I recalled there being a layer fan option when I first flashed.

I was looking through Slic3r's settings.  It looks like the cooler settings are under filament, with lots of options for fan on bridges, or if layer print times are at certain time limits, or you can always turn it on.  It seems to me that controlling the layer fan makes much more sense then controlling the extruder fan.

So the extruder fan would then be on 24/7 if you control the layer fan?

I figure I would probably just hook up the extruder fan to a GPIO port of the Raspberry pi running Otoprint...  That way I could turn the fan off remotely when the printer is idol...

I only tend to use a layer fan with PLA for that very reason.

Re: Digital Sundial

When you use the g-code to control the fan yes you are controlling the layer fan. The fan you add that is always on is cooling the cold end of your hot end.

I don't want the fan on when the printer is idle.  I think a simple relay could be used to make it on when the LED lights inside the printer are on...

Re: Digital Sundial

Well you could set up a relay that turns on based off the power being sent to the hot end or to the heated bed.  I did that to the case fan I installed on the tinyboy I had. 

On the davinvi I have installed a e3d-v6, and the fan that came with the e3d is connected to the 12v supply and it is always on. It is not a big deal, and its not that loud. Heck the fan in the power supply is louder. it was simple to set up this way. hooking it up to come on with the lights would work as well. You then just need to make sure the lights are not set to power save mode.

If you have the aio you could also set it to turn on and off with the badge light.

Re: Digital Sundial

I guess you are right.  I have 4 fans running in my computer 24/7... nothing my solar panels can't handle.  LOL.

I really want an E3D-V6.  I just feel like I should probably get out of the warranty period first...  I'll see how XYZ handles my print bed glass that broke lat night.  My guess is the warranty is probably not worth much, especially if they expect me to send in a 50lb printer.

Re: Digital Sundial

I really like my e3d. in my opinion one of the best mods I have done to the printer right up there with changing it to use repetier.

My next favorite so far has been the new bondtech QR extruder.

Being able to print flex filament at abs speeds is just amazing.

Re: Digital Sundial

You use the bondtech with the e3d?

Re: Digital Sundial

Yes I do.  The bondtech QR fits the e3d directly. so you just need to make your carriage hold the extruder.

The two of them together have made for a really nice upgrade.  Although to be honest its not a cheap upgrade the e3d v6 is $80 and the Bondtech QR is $130 so that's $210 but I can say I the Bondtech is simply awesome. its much more precise on the control of the extruder and so far has been able to handle any filament I have used in it with no issues at all.

Could you upload some pics of your Bondtech mod.

Re: Digital Sundial

So do you still need the stock stepper motor for the extruder, or is the bondtech a replacement for that?

Re: Digital Sundial

The bondtech comes with a geared stepper moto so no you cant use the stock stepper motor. That is part of why it costs more.

Note the wiring in this set u has not been optimized yet so its sorta messy.
but here are the pics

Re: Digital Sundial

Yah. but I really do love the how much the prints improved with the  e3d v6 and the bondtech  I should try your sundial.
