All I am saying is the stock firmware does not allow for the fine tuning needed to get the machine to print well. I had a 1.0 and gutted the stock controller and installed a Ramps 1.4 to get it to print what I felt was just acceptable. XYZ machines are intended in my opinion for people who just want to get their feet wet. They are not intended for final products other than trinkets and cat toys.

are you saying the printer itself is not up to the task, or I need to load repetier firmware? My firmware is 2.1.0 and have not seen validation that flash is possible.

If the printer is no good, what changes have you made to make it acceptable? I will return the printer if there's no hope for it.

I have had mine about a month and have make ok progress with dialing in Simplify3D. But, now I'm having issues with S3D unable to send some larger files to the printer. So, I wanted to try cura or slic3r. But, when I open those apps they are just blank. Are there any setup files you can export/share that would give me a decent starting point like S3D has?

I tried out of despair a different slicer (sli3er)
expecting the same blob as in cura.

But it came out the best of all prints i made. With walls of 0.73mm
I must say i printed this one with the second extruder.
Today i will do a test with my first extruder with the green pla.

I'll let you know

Oh Boy, the expected thickness is 0.42mm and you have doubled it.

I think your repetitor-firmware setting wrong. Can you post the value for step/mm of all axis?

Or set flow% to 50% and try again.

Your settings for cura and pi are very different, your cura print at 213C with 50C print bed. Your pi print at 205C with 40C print bed. Neither temperature make sense. For PLA hotend temperature is ok, but bed temperature is too low. I usually use 200C and 70C. For ABS, both temperatures are too low. I usually use 230C and 90C. Different filament are slightly different and you should start with my settings and fine tune based on results for easy bed adhesion.

Well 3 hours and growing a lot of grey hair later.
I've managed to print one using to cura slicer on the pi.
Result is "nice" only some layers didn't stick together.

BUT when using the Cura 15.04 desktop slicer it became a mess.
Looks like the z position moved way to little and the model drifted

I also had to add a solid base because the model didn't stick to the bed.
I think the desktop slider setting are added to the defaults on the octopi or repetier.
I don't know if this is a thing.

The thickness of walls by the pi slicer are 0.88mm 0.86mm 0.76mm and 0.91mm

I'm rocking a raspberry pi 3 with Octopi running and i flashed the Da Vinci with the latest repetier firmware.

I got myself a digital caliper and will start with a zero-ed out test print to do the measuring.

Re: da vinci 2.0a duo settings

null@example.com (yizhou.he) — Tue, 13 Feb 2018 23:30:32 +0000

over extrusion for sure.

2) With a caliper or a micrometer, measure the wall thickness. Let's say you measured 0.45
4) Divide the above value for the one you measured ie: 0.42/0.45 = 0.93.

Set your FLOW% to 93%(depend on the calculation) and print it again and see if result improves. I would change layer height to 0.2mm, print speed to 20mm/s and filament_diameter to 1.75mm and lower print temperature to 205C to make the measurement easier.

And how did you make Cura work with your Da Vinci 2.0A?

Well this is the calibration print i made.
It some what looks like the rendering?!?!?!

Thanks for the replies of you both.

I'll go out and get me a caliper to measure the filament.

For now i'll try and increase the layer height to 0.3

filament diameter to 1.85 and the flow to 98%

And see what it will bring me

Follow the extrusion multiplier calibration instruction and see if it improves the result. May not be as accurate as Carl's method, but it is quick and can help you identify other issue fast. When you get OK quality print and want to be more precise and accurate, spend time and effort as Carl suggest to achieve optimal result.

Also your layer height is 0.1 mm and your top and bottom thickness is 1.2 mm, that means you need to print 12 top layer and 12 bottom layer with 100% infill, it is going to take a long time to get your test result. Increase layer height or decrease to top and bottom thickness until you get quality issue solved.

For starters your diameter will never be 1.75. This is a critical value and must be accurate. You should measure about a meter length of filament in several locations and average the value. It is that value you use for diameter in your slicer. Once you do that if it still looks bad then back of your flow to about 98%. Right now you are badly over extruding causing material to collect on the hotend and then burning form being on there too long then dropping on to your print. Get the major bugs first then the minor ones. You need to get rid of this excessive extrusion first.

Your shell thickness should also be a multiple of your nozzle diameter. So for example if your nozzle is .4 then you would want to use a shell thickeness 1.2mm in order to get three shells which is normally sufficient.
