Re: SD card full from timelapses - Octoprint doesn't fully load

SD card has filled up with timelapses The video files live in /home/pi/.octoprint/timelapse/, so you can delete them to free up a bunch of space. If you've already set up SSH access, sign on remotely from your Comfy Chair: ssh pi@octopi.local cd /home/pi/.octoprint/timelapse/ rm *mpg exit If you ha...

Re: Lots of play on M2 legacy build plate- bad carriage block?

a good ~1mm of play at the corners The bearing is 12 mm wide and the platform is 200 mm across, so 1 mm on the edge means something less than 0.1 mm at the bearing race. You should be able to feel that if you put your finger across the traveling block and the rail: if that gap wiggles, then it's wo...

Re: Filament Runout Sensor without LCD

any thoughts? I have my doubts about how well restarting a print in the middle actually works, because getting molten goo stuck properly to anything , let alone cold plastic, seems remarkably difficult, but … Start by being able to reload & recalibrate the firmware you're using now , because if you...

Re: Why use 19v for RAMBo?

power RAMBo like this, right? Seems reasonable. Having two separate 12 V supplies may seem excessive, but isolating the logic from the platform heater's killer current is a Good Idea™. Not running that current through the RAMBo is even better, which is what you're accomplishing with the external MO...

Re: Why use 19v for RAMBo?

get a $350 direct drive printer from Amazon A friend did that and had a good out-of-box experience, then added a few hundred bucks of this-n-that to bring it up to solid usability. You've already got much much better hardware, apart from the (probably) crap Z-axis motor [1], so it's better to drop ...

Re: Why use 19v for RAMBo?

a Dell 12v 18a for heatbed and a 19v 6a for everything else The 12 V platform heater was a catastrophically bad mistake, because the heater draws far more current than the wires & connectors can handle: https://softsolder.com/2019/03/12/makergear-m2-bed-heating-failure/ If the connectors at the RAM...

Re: Filament Drive Pinion gear slipping on shaft

"small hole gauges" My set bottoms out at 3 mm; smaller holes get measured by guess and by gosh. For holes you (well, I) can actually see , telescoping gauges come in handy: https://www.amazon.com/Pc-Precision-Telescoping-Gage-Set/dp/B00R5E5PI6 To the best of my knowledge, I've never deployed the t...

Re: Filament Drive Pinion gear slipping on shaft

magic juice work on that? The Loctite 648 data sheet says it's good for 6 mil = 0.15 mm gaps, a generous fit, so it should work for what you've got. Definitely: roughen the shaft, meticulously clean shaft + pinion bore, gimmick a fixture to hold the pinon in the right position so it doesn't wobble ...

Re: Filament Drive Pinion gear slipping on shaft

use JB with the new gear Although I'm a big fan of JB Weld, it's probably the wrong hammer for the job, because epoxies depend on a mechanical joint you don't get with a shaft, even a sanded one. Threadlockers are designed to lock threads , not smooth-ish shafts to pinions. Some info from the Locti...
