Tips for Replacing Filament Drive Gearbox Pinion?

My pinion gear is getting a bit worn, and I have a replacement. I've seen various comments that they may be installed with an adhesive. At a minimum it's probably going to require a tiny gear puller, maybe along with some heat. Any recommendations on a puller the right size? If I need to apply heat,...

Re: Cura 2.3.0 MakerGear M2 file

At some point, they reversed where the Z axis "home" position is located. On the Rev. E, the Z limit switch is with the platform all the way down. I'm not sure when they changed, but the older versions of the M2 had the Z limit switch at the top. It sounds like that's where your problem originates.

Re: M2- Revision G not extruding

The frame doesn't look that different from my M2E, but the way they mount the bed cooling fan to the extruder is definitely a departure. However, I'm not sure I'd consider it an improvement...

Re: M2- Revision G not extruding

First thing to check is whether the extruder motor is turning. I put a thin black marker stripe across the back end of the motor shaft so I can easily see if it's going round & round. If it isn't, you may have an electrical problem. If the motor is turning, it's most likely that the extruder has jam...

Re: Layers off centered & weirdness

If it's always in one direction, I'd suspect an intermittent connection to the drive motor.

Re: The Dreaded Filament Drive Clicking Sound...

Thanks for the comments! I'll have to check the notes I have on doing a cold-pull, which I believe you do with the extruder unmounted. I've been thinking about machining a "handle" that would clamp onto the extruder the way the normal mount does. I'd prefer not to chew up the mounting surface with p...

The Dreaded Filament Drive Clicking Sound...

I switched from red eSun PETG to some white HatchBox PETG, and after purging the extruder for a while and starting a small print job, I started getting clicking (actually, more of a clunking...) from the printer. The part was long & skinny in the Y directions, and it was most noticeable when it was ...

Re: Cura 2.3.0 MakerGear M2 file

I've been using S3D, and recently upgraded to the latest version, 4.1.1. Well, they've changed a bunch of stuff, and I spent a couple days dealing with adhesion problems because they altered the way the first layer height works. I've also seen a host of other issues come up on the S3D forum that mak...

Re: Nylon

You may find that PETG has all the properties you need, and it is generally much easier to work with. It doesn't suck up moisture for one thing.

Re: Makergear M2 stops extruding after many hours midprint

If your filament drive tension is "loose" as you say, all the gear will do is chew off filament material. It needs to bite in and not slip. If you retract the filament, or observe it going into the hotend when it's running, you should see definite teeth marks when the tension is set right. Check out...
