Re: filler for pla

I control how support breaks away by adjusting overall layer thickness. If support doesn't snap right off, increase your layer height a little. .1mm can make a significant difference. Don't increase it too much or the build on top of your support will get ugly.

Re: nema17 dampers

Scroll to near the bottom of page 7 on this thread . I added washers under the mount to tilt the motor shaft out, so then when tension is applied the shaft returns to perpendicular to the machine. My dampers have not lost tension that I have noticed - or I have removed the motors often enough that I...

Re: TIP - Removing PEI Sheet from substrate

FWIW, I wrote this up on another forum - I should take the time to get some photos or video of the process, but until then: I use 3M 468MP Adhesive Transfer Tape, 12" squares from Amazon to stick my PEI to the build plate. I use an aluminum plate, but the glass should work fine. I use a 3M 71601 Blu...

Re: The GearMaker M2 Kit for Newbie?

My first 3D printer was an M2 which I upgraded to dual extruders. In the end I only messed with shooting both barrels a handful of times. Over time I learned to get good, easy to remove support with a single extruder. The upgrade I valued most on my M2 was getting a RasPi micro computer running Octo...

Re: Printing Makergeeks PETG

My PETG prints got a lot cleaner when I eliminated Z-lift on retraction - and I also avoid movements over open area (don't recall the name of setting option in S3D for that). When calibrating the extruder, I deduct 5% from the nominal calculated multiplier to ensure I'm not over-extruding. Z-Lift cr...

Re: How much gantry curvature is too much?

I have had two M2 printers - the first was returned under warranty - but both needed to have the X rail shimmed to get a good first layer on large parts. I haven't seen any significant issue on the Y axis. One thing I'll say about using an indicator is that even with the Rev E 4-point support the be...

Depends on how my wife will feel about burning the adhesive off in the oven. Might get stinky.

TIP - Removing PEI Sheet from substrate

Have a well-used PEI over Aluminum bed that has started to release the PEI around the edges. The 3M adhesive sheet has dried out around the perimeter and doesn't have any stick left. The center however is still well bonded and I was not looking forward to trying to pull things apart. Wondered if fre...

Re: How to solve this printing problem? (ABS printing)

I generally run the layer height at about .5x the nozzle diameter, and lately I've been matching the extrusion width to the nozzle diameter (based on good results with another printer). If I were going to print ABS with a .35mm nozzle, I'd use a .35 to .40 extrusion width and a .175mm layer thicknes...
