20161207 Dev Firmware
Posted: Wed Dec 07, 2016 9:30 am
Just pushed some new firmware into the dev branch. Use at your own risk!
Here's what changed from the preview dev:
-Horizontal Radius now checks a maximum of 4 times when calibrating w/ G29. Almost every printer I tried this on nails it in 3 or less, but this is insurance so you won't have to run G29 twice if your horizontal radius starts really out of whack.
-G30 (with no args) now double taps the bed at the current X/Y and reports "PROBE-ZOFFSET:" in the terminal with the +- height (mm) of the tap from Z0. This allows us to use dc42's least squares delta calibration tool. More tweaks and instructions will be forthcoming, but this is the big needed first step. Feel free to play with it, again, at your own risk.
-G30 will also decrease probe sensitivity if needed, but it is highly recommented to run G29 before running any G30s as it will continually tweak the sensitivity until it works on all probe points.
-G30 S2 (which is called from the old calibrate scripts) will still probe and set the Z height.
-Configuration.h now has all the printer specific DEFINEs grouped together to more easily change settings for an individual printer instead of hunting up and down the entire file.
There are more tweaks and changes in the pipeline, but most of what lies between this version and stable code is testing, instructions, and more testing. If you try this firmware, please post your experience in this thread so I know of problems/issues/etc that others are having. Working hard to have this new and better code fully working, tested, and in to master/stable as soon as possible!
