Topic: SD4 top layer infill issues

so i have got my new E3DV6 installed and extruding correctly. my hollow cube wall thicknesses are .42 exactly.

but i am having a couple issues.

1. my top layers are not filling 100% the tops do not meet up with the perimeters at all times. ( see picture)

2. my 10mm x 10mm test cubes are 10mm on 2 sides and 9.5mm on the other 2 sides. what is causing this?

my extruderis correctly calibrated and i have tensioned my belts evenly.

thanks

Re: SD4 top layer infill issues

Lets start with your perfect calibration.  You have a .40 nozzle and need to be shooting for .48 not .42 so dial that in first.
Should just be a simple extrusion multiplier change.  Then, what axis measures at the 9.5 on your cube?

really? .48?

i thought for some reason it was .42, but i can make the change very easily this afternoon, and then i will reprint the 10x10 cube and report back the results.

thank you very much!

Really, I am working on updating the WIKI right now.
Don't forget to change your extrusion width's in your slice profile.

I reclaibrated to .48 on my open cube walls, infill seems much better, but my 10x 10 cube is still only 9.55mm on the x axis. Y is 10 exactly.

how can i adjust the x axis?

What infill?  Your open cube should have Zero infill and 1 perimeter, and the wall thickness goal is .48...is this how you printed it?

sorry, infill is now fine, but my 10x10 cube is only 9.55mm on the x axis and 10mm on the y. it should be 10 on each.

Re: SD4 top layer infill issues

.5mm left to right, probably tighten the x belt or check that your nozzle is secure.
Past that you're adjusting VREF for that stepper.

Re: SD4 top layer infill issues

There is also just adjusting the steps per mm on the Y axis. Might want to check that before fiddling with belts or vref. I know when I first got my solidoodle, the default values were considerably off for both X and Y.

Re: SD4 top layer infill issues

It's very odd that the steps per mm would be off on X or Y, but if you check in RH under EEPROM Settings, it should give you the current values and allow you to adjust them.  Not at my machine, but I think the default for both X and Y is 88 unless they have changed to GT2 pulleys...

If they both are reading the same, I would investigate vref and belt tightening as wardjr stated above...
