Hi,
Hi Guys…
I am new in 3d printing, i bought Wanhao I3, and confused with leveling and calibration,
i need to buy 3d printer, specially for architecture models and some decoration elements like vase and wallpapers, and i need printer with auto leveling, and 2 Extruders, i am confused with Felix Pro1 or Cube Pro? any help or advise? or even other models?
Thanks…
Auto leveling is not very good yet and still has issues… I know of someone with a Robo that has auto leveling and its been leveling too low which is causing him printing issues…
If you want to get into 3D printing you better be a tinkerer… the industry is too young for you to find point click printers out of the box. They all need tuning/fixing/modding even at the $3,000+ price range.
Are you sure you want to deal with 2 Extruders? They are more difficult to use/configure/print with/maintain than simply leveling the print bed on a Wanhao i3. You really need to be comfortable with leveling first… Doubt you will find a auto leveling dual extruder reasonably… because just changing the nozzle on one extruder can completely throw the leveling aspect out of wack and takes alot of fine manual adjustments to get it level again.
Also on your Wanhao i3 have you removed the tape over all the end stop switches, this is seriously like the #1 reason for most issues with the Wanhao i3 bed leveling among new owners.
HI…
Thanks for reply, actually, i need 2 extruders to use support material PVA, and for the tap, i not get you, but the machine sometime good and bad print, some they advise me to use A4 Paper, other Bussines card, and i am confused 1 month tl now and not get the final result good,
The issue with dual extruders… you have to level them flat… if one is higher than the other than your either printing too far off the surface with one head… and if this is happening when the second head gets near the freshly printed layers it rubs it and can cause alot of defects or even completely ruin the print. Next issue is trying to line up the alignment between the 2 print heads (so they print in the exact same positions) this can often be quite a task, it took me all day to get one printer aligned just right. with countless hours of starting and stopping test prints and adjusting settings… Also you dont -need- 2 print heads to print supports… But this does depend on your printing needs like you mentioned PVA… I print all day with single head and still print supports but the support is printed with the same material I am printing in… But if you have a good slicing program (the software that sends codes to your printer) then the support comes off very easily with minimal surface issues of the print.
I am guessing with that final part your talking about trying to level a printer you have already? Use standard printer paper… the key is for it to slide between the print bed and the nozzle tip with minimal effort… if you can move the paper around freely need to get closer to the nozzle… you want to listen and feel at the same time… once you can hear the nozzle dragging on the paper and feel that it started rub the paper then you know your getting there. you dont want the paper to be stuck between the bed and the nozzle though… and you need to do this process in various places around the print bed (per whatever directions or program your following for your printer) but once you do this… do it again once your done… its good to do this 2-5 times until your no longer making fine adjustments when checking… this is very common and is one of the core elements of good 3D printing.
Try PrintrBot. They have auto leveling on their printers and it works super great. They use Marlin firmware which is open source. I’ve both PrinteBot and WanHao I3. WanHao is less than a month and PrintrBot is a year old. I have already started feeling the pain of manually adjusting the leveling screws each time.
PrintrBot has some cool features (I guess it’s default in Marlin firmware) that allows tilt compensation. If your bed is bent or the surface is inclined, the printer will compensate for it.
