Solved Extruder multiplier question

Hi,
In running the test for under/over extrusion I found for 100mm it's only printing out about 90mm. After I try a atomic pull tonight to clean it if it's still a problem then would setting my extruder multiplier from 1.0 to 1.1 fix the problem since technically it's only extruding at 0.9 or is that a really bad idea?

thanks

 

Ok I watched through the video again and I just have one more question. Lol not sure why running a full firmware update on my printer makes me more nervous then when I updated my TV firmware which is why I'm running through the whole process.

Ok so for example if I get this for a M503 command:
READ: echo: M92 X80.00 Y80.00 Z800.00 E723.38

I then take (723.38*100)/90 = 803.75

I can use a M92 command (M92E803.75) to temporarily change the extrusion value and if it works I can use M501 to save the changes out permanently rather then needing to do a full firmware update?

thanks

 

Ok thanks,
Yeah after I kept getting M501 when I tried changing the extruder steps per mm setting I think I'll go with Firmware if it's needed.
I tried an Atomic Pull last night just in case it was that and I was sort of successful. It was either that process cleared something or maybe I had the tension all wrong on the hobbled bolt because it's extruding accurately now.
I printed a cube and it's a bit better but first 2 top layers were pretty much just extruding in the cube center not connected to the walls I think I kept the layers at 5 or 6 count and the layer height is 1mm

I saw the bridging multiplier was set to 100% and the help file stated if you lower it that helps with sagging. I set it to around 75% then a little lower for the second one which gave me these results.


I tried upping the outer overlap by 5% which gave me this.

still thin on the top but when I opened it up the first layers look better then they had.

Could it be the temperature is too high for the first few bridging layers and it's just sticking too much? If it's not that I welcome any suggestions as to how to make this better.

thanks

 

Why don't you just use some infill rather than trying to bridge? 10% or even 5% will fix your issues. If you are trying to set your Bridge settings, I would try a different calibration thing first. I used this one to get my settings for PLA bridging: http://www.thingiverse.com/thing:12925

 

Thank you, I tried the calibration thing from the link you sent and I got this.
I might try to tweak a few more settings after my next print but the last time I tried printing the bridge calibration was before I got Simplify3D and it wasn't anywhere near this good.

 

Try this one next: http://www.thingiverse.com/thing:40382

This it was not even a challenge for my Robo R1+! S3D has definitely made my life a lot easier!

 

I just finished up that one, not bad at all. The 70 degree did get a bit wavy but it still worked better then I thought it would. The wavyness could have also been in part from getting up to 82 in the room it was printing.

 

Not too bad, it looks like you have some stringy issues now though! It's a never ending battle!

 

Indeed it is, especially where I have my printer it's hard to keep the ambient temperature under 80 and it starts oozing or stringing a bit more. If I tweak the settings I'll probably try the DPrime Test Object to reduce stringing.

 

Lol so I found a cooler looking model to try for stringing issue and my real problem with the stringing. Now I did just get Simplify3D not that long ago so still learning everything about it like for example checking both tabs for retraction settings Retraction wasn't turned on at all, which makes that overhang one not too bad considering it wasn't on at all
I printed this out and there's as few strings on the other sides too.

 

Ok I tried setting the minimum layer time but I was watching the end and it almost looked like the extruder was a hair too low and was pushing the filament around but it's just the top where it happens. Could it be too many top layers or parameters or should I make the layer time shorter?
thanks

 

What is your current setting? I still have the default set at 15 sec and have not had any issues. I can try to print that thing and see what happens. I need something to print tomorrow anyways!

 

It's at 10 seconds for the second one, I had it at 15 for the first one so I had it backwards and should bump it up to 20 seconds.
Just wanted to doublecheck the fan speed should stay at 100% after layer 2 because the last layer speed is set to 100% right?
