Re: Used M2 Rev E bent Z lead screw.

couldn't take the shaft out of the motor Yeah, the leadscrew is not a separate thing! Coupling a leadscrew to a motor would make the whole stack much too long for the M2; as it is, there's enough room for a box o' electronics down there. PSA for those in the future: DO NOT disassemble a stepper mot...

Re: Used M2 Rev E bent Z lead screw.

it jams and binds at the base It's faintly possible you can un-wedge it at the sticking point by loosening all the motor retaining screws and re-tightening them to allow things to line up again, but it seems you've already done that and it didn't work. Basically, once you bend it, you cannot mend i...

Re: slipping filament - motor shaft wiggly

an opening between the gear assembly and the stepper motor that shows the stepper motor shaft The only rotating parts you can see are the gear shaft (inside the filament drive gear): IMG_20200702_095320 - Makergear M2 - filament drive gear.jpg And the motor shaft (toward the gantry): IMG_20200702_0...

Re: slipping filament - motor shaft wiggly

then I change filament and filament now won't feed The new filament may be oversized enough to not quite feed through the plastic block; some folks have found passing a 2 mm (75 mil) drill through the block clears the blockage. The symptom will be the nice gouge carved by the feed gear into the jam...

Re: M2 (2015) Power Supply Wire Gauge

the wire gauge for the power supply wires? If you have an old-old 12 V platform heater, DO NOT extend the wires, because the current is too high for anything practical to work. If you have a 24 V heater, then go for larger (lower numbers) than 14 AWG silicone insulated stranded wires. Don't use che...

Re: warped PETG prints

turn off fan for all layers Do that thing, along with mouse ears on the corners, and it'll be as good as it gets. You may need more brim / mouse ears for difficult geometries, like a thin-bottom + thick-walled box. Don't be afraid to apply more brim, perhaps with two layers, in those cases. I've be...

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

"failed to autodetect serial port" replacing them with new copies from a fresh Raspbian install on another SD Makergear Octo fork appears to be dead and hasn't been updated for over two years. All those are related: you can't mix-n-match new boot files with ancient OS versions and expect Thing Will...

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...
