I have a Wanhao I3 Printer. I Installed a glass bed with PEI, my first couple prints went like a dream, Then for the last 5 attempts I cant get it to Print anything. The first 3 attempts started printing into thin air about when they were 3/4 done. The last couple however start printing too high on the second layer. I cant get the back Right corner to level with the rest of them. I tried adjusting the y-axis rods etc… to no avail. It’s not the glass bed. I had 2 really good prints with it on. Im at my wits end I hope someone can help.
Sounds like you may have a clog or partial clog. As for leveling the bed, have you tried going completely back to all springs compressed and then leveling? Also, level the bed while it’s warm (60°C) as it does tend to warp as it warms up.
I thought of that and today I purchased some cleaning Filament from Amazon so Hopefully that does the trick
Hey!
I also have the wanhao i3.
id go back to basics if it were me.
Id check the level of the Extruder axis first and realign my bed.
Did you put the limit switch up a notch?
I personally use prit stick or glue stick whatever you want to call it. Swear by it. Everything has stuck to it without fail. As long as the bed is level there will be no probs.
Let me know if you still have probs after checking all that.
might be a good idea to shoot your nozzle up to 250 and pump a load of filament through it and watch to see if it’s coming out straight etc.
Hello,
Usually when the printer starts printing in mid air like that it is due to the SD card. Wanhao sent a low quality SD card which is well known in the Wanhao community for those issues. Try replacing the SD card. If you are using CURA, the latest version is conflicting a bit with the Duplicator. Just in case you upgraded your Cura version.
Was just thinking, you mentioned that 3 attempts started printing in mid air when they were all 3/4 done.
Check, I believe someone has already mentioned it. But you may have a partial clog. and Your temperature is off. The print gets to a point where the printer thinks it is feeding filament when in fact it could be a partial clog that may or may not clear on its own. This could be your temperature… What are you printing with? Also on your last inquiries you asked about raising the end stop for a glass bed, Did you do so. Wanhao has pre drilled holes for the end stop if you go with glass. This in fact will help you will your bed alignment thus improving your adhesion.
Once I installed the glass bed and PEI adhesion is no longer a problem. Yes I raised the end stop. It used to be way too close to the bed after I installed the glass now its too high only on the back right corner I can get every other corner level. I level with the bed heated as thats what I was told to do. I am Printing with PLA.
It deosnt stop in mid air it continues to go just filament comes out erratic or not at all. I am using usb so not an SD card Problem.
how should it come out straight or curled when you pump filament through?
As far as glue stick, as of right now I dont need it because when it does print, it sticks to the PEI really well
Ok sure enough. Good deal getting that glass bed. Well, I had that problem as well, where the bed would be slightly higher on either the back or front. Inclusive it was my only problem so far, that I had to contact Wanhao, cause the Y axis was making grinding noises. I thought it was some bad bearing, But soon found out that the Y rods were not sitting level, so I loosened both and readjusted them so that the bed runs smooth and level. I used a level on the bed to help me with it. So PLA, print 195-200 with the bed at about 60. Fans will be on. Printing speed 40-50. With your Extruder position let that filament flow about 20mm. See how it comes out. It should come out straight down, It it curls, you may need to get that partial clog taken care of. Good thing you have some of that cleaning filament coming. Works great. In the meantime, you may clear the clogg by raising the temp to about 230 and let the filament flow for about 40mm or more. Then slowly go back to printing temp. I always, raise the Z and let the filament flow before printing, That way I know I don’t have a clog. Then I just give the command to print from there.
Scott, Good morning. Hope you have been able to fix your issues.
Have you tried printing with the SD card? Save the file as a Gcode on your sd card and print a test file, see how the printer responds.
Compare this PLA setting with yours. See if it helps.
Layer Height .16 Shell Thickness 1.2 Bottom/Top Thickness 1.2 Print speed 40 Printing Temp 195 Bed Temp 60
Filament 1.75 Flow 100 Nozzle 0.40 Retraction speed 25 Retraction Distance 2 Initial Layer Thickness .3
Initial Layer line Width 125 Cutoff object bottom 0.0 Travel Speed 60 Bottom Layer speed 10 Infill speed 0.0 Top/bottom speed 0.0 Outer shell speed 20 Inner shell speed 0.0 Enable cooling fan YES
1) disassemble the printbed and check the lower support part it can be bent - thats why one of the corners is lower
2) check Z motors illigment
