@puterpro said in "Backup" for 12V systems if powerloss?: @PlasticMetal - Those are sweet units! Wish I has room for one. Well, I certainly don't have them in a rack. One is on a metal shelf (restaurant-style wire shelves, plenty of air circulation), & the unused one is over in a corner.

Work with one and rotate the assembly around the filament using a spare stepper drive, or perhaps target that as stage 2 of the testing. Read up on the laser filament monitor tests and get some of the filaments that caused large variations or problems with them. How are you planning to verify your system? I've found the experimental noise on the weight of small test parts to be significant. Solving under and over extrusion issues is a great aim but filament diameter is one part of the puzzle which other projects are also working on such as the magnetic filament monitors towted potential capability to automatically calibrate non linear extrusion. I'm tackling calibration process issues myself this week and have decided to test setting my extrusion multiplier to 1 then adjusting the filament diameter to correct wall size, adjust extrusion multiplier over a sequence of solid 20*20mm test coupons, and finally tackle offset and scaling issues. This is before taking pressure advance, retraction settings, and extrusion correction in any detail. Setting the temperature has been far too vague for my liking so far and mucks up other calibrations when I've had to change it later on. Edit: I'll know I've got things nailed when a causal observer can't accurately tell what machine a test part has come from. I feel a coke/pepsi style test with some dissinteredted family members coming up!

@manyakus said in Converted Ultimaker 2+ to Duet Wifi - Interface to UM2 LCD?: Im in the process of converting Rostock Max v2 and also want the rotary control knob for Z height control. Any way that we can implement a rotary control knob? With the Duet WiFi/Ethernet, not currently. With the Maestro, a 12864 display + rotary encoder is supported.
