M405 in combination with M404, would be very handy. just bought 3 rolls of china-sourced "high" quality PLA and the diameter goes to 1.6mm 1/2 way through the spool. 1.75/1.6 = 9% but squared (for area) is a TWENTY percent variation. not having to worry about this - particularly on large objects where the diameter could potentially signifncantly change during printing - would be really good.

chris! hi! fantastic to see that you're keeping up-to-date and doing Makefiles. very relieved. i'm investigating the feasibility of using an off-the-shelf ATSam3Xe (arduino due) with the TRAMS Reference Design. 2160 steppers (if i recall correctly.. edit: i didn't… they're TMC5130's) but.... they're soldered to the board just like they should be (so that heat can properly dissipate!). in theory i should be able to start from radds, just have to see how it goes. anyway just wanted to say thank you so much for doing the sane thing and providing a Makefile. now there's no need to install 350+ megabytes of crap just to compile a 100k executable...
