I finally got a good print with Simplify3d set at 0.2mm with a 1.02 extrusion mutiplier, first layer: 90% height, 100% width and 50% speed.
When I set it to 0.1mm(the only thing I entered), it told my first layer to F-off, under extruded, went too fast and just made a mess. It makes zero sense to me as to why I have to change the first layer height to 200%, 225% width and a 30% speed to get the ugly bottom layer you see in the photo at a 0.1mm height resolution. I’ve read a few things on the forums, and they seem to be pointing in all sorts of misguided directions.
Any ideas of why it does this?
First instinct is that your zero isn’t actually zero but some offset. That offset worked with a 0.18mm+offset first layer but is killing you with a 0.09mm+offset first layer.
You can over extrude that first layer to150% and get it to fill, but it looks a lot more like you don’t have your z offset set right.
Also, if you have your first layer height set at .2, I would suggest upping it to .3 for a better layer.
I noticed that the a8 prints at a different height depending on the slicer that you use. How does it do in cura? I think that it has a built in z offset that only some slicers use correctly.
Does it return a value when you give it a m212?
Different slicers assume different tramming gaps. The slicer programmers don’t know whether you used a piece of newspaper or a business card or a contact probe or a feeler gauge to set your first layer gap. They have to make a guess. What you’re seeing is that their guess isn’t a good match for YOUR first layer gap. You need to adjust your Z offset or tramming practice to suit.
What I recommend is 100% width, 25-50% speed, and whatever % height gets you to 0.25-0.3mm. So for 0.1mm layers do 300% first layer thickness. Make sure you lower the first layer speed as needed so the flow rate (heightwidthspeed) isn’t too high for your hot end.
Is raft turned on in s3d? That looks like what mine does
I entered 300% height, 250% width and 30% speed for first layer. I does fine with it’s initial purge line across the table, but raises up about 1/2", travels to the middle and tries to print in mid air now.
…what? That doesn’t make any sense. It shouldn’t print the purge at a different height from the first layer. Unless you accidentally did 3,000% lol…
I’m slowly figuring out what is going on with it starting off in the middle of the air. I setup two profiles for something I was printing. One of which was a lower-lower resolution print of the base, then onto a high resolution. I just figured out how to go back and change that option.
