Tips for installing OpenCreator that I wish I'd known the first time

I ran into a bit of a snag when I was first trying to get the material flow dialed in, similar to how you guys are talking about initial setup. I was using PLA, specifically a brand from XYZ Materials, and I noticed that my initial layer adherence was inconsistent even after a decent purge. I figured I needed to adjust the Z-offset, but instead of just fiddling with that parameter, I ended up looking into the extrusion multiplier settings in OpenCreator. My hunch was that the default profiles were perhaps too aggressive on flow rate for a wider nozzle, so I went into the slicer interface and lowered the volumetric flow by about ten percent. It seemed to stabilize the first layer line much better across the whole build area. This small tweak made a difference to the print quality on my small test pieces, which is what really sold me on the change. It took about an hour of testing and adjusting the slicer profile before I felt comfortable moving onto the actual project. It's less about the hardware failing and more about these little software parameter tweaks making the difference. For future reference, I found that when the layer shift error started occurring, the slicer settings were the first place I checked, not the physical head itself.

The babysitting part hits home. I've got a spare phone clamped to a tripod watching the bed over the network now, and last weekend that saved a 14 hour job when the filament sensor gave a false empty about halfway through. I let it sit for the full three minute pause it asks for before resuming and it picked back up without a blob. Also keeping a plain text file of every setting I change has been the only reason I can roll back when a tweak makes things worse.

On the update side of things, I learned to wait a bit before jumping on new versions. I updated the week one came out and lost a bunch of my tweaked profiles in the process, had to rebuild them from memory. Now I export my profiles to a usb stick every time I change something, and I let new releases sit for a couple weeks while other people find the bugs for me. Also worth checking the fan settings on whatever community profile you grab. The one I started with had the part cooling way higher than I needed for PLA and it took me ages to figure out why my overhangs looked hairy.
