Re: Is the M2 a dead end

MG could make these available to their existing customers IMO (*), there's no economic reason to do so and many reasons to avoid selling piecemeal upgrades. There are many "official" iterations of the M2 in the wild, plus hotrod versions like mine, and myriad "standard" configurations. Any upgrade ...

Re: Questions from a new owner (of old M2)

Welcome aboard! Being a crusty old-timer, I have exceedingly strong opinions not lining up with current wisdom, so fetch your salt shaker and apply as needed. None of this is meant to be discouraging, but I don't do unicorns & rainbows. the single power supply If it's an old-old M2, then check the l...

Re: files

Does it matter what files you use, stl type or others? It depends on which solid model file types your slicer will accept. For example, Slic3r can handle STL, OBJ, AMF, and 3MF, although I've never needed anything other than STL. It's worth mentioning that NGC / GCODE files are not compatible betwe...

Re: Heat Insert Technique?

That's nice work! Instead of a bevel, would a cylindrical recess 0.5 mm larger than the insert and two or three threads deep (0.5 mm, max) suffice? Set the insert into the recess, resting solidly on its bottom, then nail it with the heated tool. I don't do enough inserts at any one time to justify y...

Re: Heat Insert Technique?

use threaded brass inserts for the cover screws Love 'em, but they're definitely finicky. The real problem comes from 3D printing's crappy tolerances: ±0.1 mm in hole diameter is the difference between "fits OK" and "falls out". For low-stress applications, I just ram 'em into place with the drill ...

Re: problem with first layers

bends away from the bed glass The basic problem looks to be geometric: the part has a tall outer wall around a recessed center. All the plastic shrinks as it cools, the rim exerts a tremendous upward force on the base as it tries to contract radially and vertically, and eventually one side of the b...

Re: Z stepper drops during pause

Do you know where to find such parameters? Dunno, because I've avoided LCDs and mid-print tweakage, but I think Marlin runs specific external routines when such events occur. Searching the doc for keywords like "custom G-Code" and maybe even "pause" might be productive; matching the doc to the spec...

Re: No Heated Bed = Power Connector Fail

printing 20 hrs a day 5 days a week Yup, industrial usage on a consumer-grade machine will do that. Bonus: The wiring to the extruder and platform has surely worn out, too. While the machine is dead, take the looms apart and see what's going on inside. If (when!) you find any chafed wires, it's tim...

Re: Z stepper drops during pause

Marlin has two configuration files:
  • Configuration.h - "basic settings"
  • Configuration_adv.h - "advanced settings"
It's in the other one … [grin]

Re: M3-ID Octoprint 'Still stabilizing'

an existing stl and scaled by 150% in S3D If the STL has a gazillion faces, perhaps creating very smooth rounded surfaces, then the G-Code commands must specify teensy moves that don't do anything other than waste time. Those models happen when folks specify, say, 0.001 mm arc tolerances or make cy...
