Topic: Troubleshooting prints with Repetier on 1.0A

Hello All,

A while ago I posted about increasing the strength of prints. Some of the suggestions were to use the printer with repetier software as well as to use a filament other than the XYZ filament. I finally found the time to make those changes and am now using repetier with slic3r on my 1.0A, as well as excelfil filament.

I've been messing with settings and was able to get a smaller print working fairly well, however, as soon as I tried a taller print (coffee mug looking thing) all the issues appeared again. I've attached some pictures of the print, hopefully you can see that the side walls are fuzzy with little bits of filament hanging over the sides. There are also little bumps on the top layer.

Is this overextrusion?

What are the print settings?

Re: Troubleshooting prints with Repetier on 1.0A

Bed Temperature - 90
Extruder - 230

Layer Height - .1mm
Infill - 50% (honeycomb infill, top and bottom layers are rectilinear)

filament diameter - 1.75mm
Extrusion multiplier - .92

Re: Troubleshooting prints with Repetier on 1.0A

I would not use anything less than .15 for a layer height on a Da Vinci. They just can'tdo less reliably. I would also put my multiplier back to 1.00. If you need it lower then your steps per mm are not calibrated correctly on your extruder. You did not list your speed but I would not go over 25mm/s when even trying a .10 layer.

Re: Troubleshooting prints with Repetier on 1.0A

I consistently use h=0.1 for most all my prints.  Always turns out well (even during the dial-in with Repetier and both Davinci and e3D nozzles).  In fact, though I use Simplify3D, out of the box, even with xyzware, no problems with h=0.1...

Then you got lucky and got one of the few better units. I know mine and I know of several others that could not print less than .15 even with Simplify3D..

Regardless in the issue at hand I would still slow down and raise the multiplier.

Re: Troubleshooting prints with Repetier on 1.0A

Totally agree with carl...   I did get lucky and early research verified a short/limited production of printers with good parts (mine was delivered with spec's for running at 120mm/s).  There was an article in CNET new early this year.  They dialed that way down for follow-on production.

I ran at 4000 mm/s for a long time before dialing down to 2000 after rod bearing brackets broke (and, believe it or not, they are replacing the parts but they are on back order because of too many broken brackets.... LOL).

Re: Troubleshooting prints with Repetier on 1.0A

My printer use to print pretty well at .1mm using the stock xyzware - surely the printer could replicate those results using Repetier and slic3r?

I only reduced the multiplier because I thought I was seeing over extrusion. It looks like all my speeds are way too high.
