Topic: print quality question - UPDATED

I have printed 2 pieces and compared them.  They are printed  on A Replicator 2X dual extruder.
Here are the Settings.

ABS filament
Simplify 3d software
.2 Layer
50% Rectilinear infill
Using prime piller
Using Ooze shield

Thanks

Re: print quality question - UPDATED

First thing I see is filament that looks to have moisture in it. All those voids and rough areas are indicative of wet filament and possibly low temp.

Printing since 2009 and still love it!

Re: print quality question - UPDATED

I will bump up the temp. they just came off a 12hr dehydrator time last week.
the humidity in the room the printer is a constant 49%
and a small room dehumidifier runs 24-7

Thanks
Dale

A week at that level is more than enough time to see what is showing in your print. Mine stays around 25% and I can see evidence of moisture after about two weeks.

Re: print quality question - UPDATED

i have the software set at 230°c and I checked the nozzle tip with a calibrated type K meter
and it reads 187°c. That is a 43°c difference.  I am going to heat it back up and check the end of the heaters.

Re: print quality question - UPDATED

The end of the nozzle heaters measure 221°c that is a 34c difference

Re: print quality question - UPDATED

The nozzle temp and even the heat block temp will be different depending on where you measure. You have to keep in mind the thermistor is embedded in the heat block near the heater so it will read the highest temp.

What I try to do is measure the point where the nozzle mates to to the heatblock. That should give you a good idea of the melt zones temperature.

Base on what the difference in that and what the thermistor is I set the temp to achieve the desired temp at that spot I am measuring at.

So if you see a difference of 34 degrees then add 34 degrees to your set temp to get that point up to your desired temp.

This was one of the reasons I got rid of the Makerbot controller my CT'c had. You can't do a PID tune on the hotends and get them more accurate.

Re: print quality question - UPDATED

this evening I will print a cal cube at the current temp with each nozzle and then raise the temp 10° and see if that makes a difference

Re: print quality question - UPDATED

49% humidity is rather high, to be honest. between 25-30% is considered "normal" - not to damp, not too dry.

i get that you live in Florida, and humidity is always an issue.. but try drying the filament for 24hrs and then using it right away.. i think you may see a big difference in the print quality.

Re: print quality question - UPDATED

My dehumidifier is running but not pulling in any water. I thought my wife was emptying it and she thought i was dumping it.
Time to get a new dehumidifier.

Re: print quality question - UPDATED

there are multiple design of filament spool that sit inside of plastic box with reuseable moisture absorbing pack inside. you do need drill smal hole on the box to allow filament go through. If you live in Florida, this can be big plus in addition to dehumidifier.

I live between the Delaware river the average summer humidity is   Delaware    Wilmington    morning  RH % 85 afternoon    55%

and the Atlantic Ocean   New Jersey    Atlantic City    89%    59% i dump the dehumidifier  twice a day . I have thought about making a dry box . I probably should do it at least one. also dry out some filament.

Re: print quality question - UPDATED

I see lots of z-band show up randomly in the picture, it can be over extrusion, but there is some random pattern that can not be explained by over extrusion. Double check with your filament spool rotation. My feeling is occasional trouble with filament feeding cause these random pattern in z-band. It might be something else, but filament spool issue is easy to check and easy to solve. you can print some ball bearing filament spool and filament guide to help reduce trouble in filament supply.
