    For me, it isn't as much about the price as it is about being able to control the quality. I wanted them to be crisp, clean and consistent so I could stand behind them, and for me that meant making...

    Fixture for CNC Milling Hobbed Bolts

    I just posted a YouTube video showing my fixture for milling hobbed bolts. I thought folks here might be interested.

    I was trying to come up with a way to make high-quality hobbed bolts without...

    Thanks for posting the photos. That looks really good. How much vertical motion does it produce, and how does it register? Does the washer bottom consistently? Do you get any X/Y artifacts?

    I...

    I have split a piece of glass with ABS before. I had eight parts lined up so as they warped, they all pulled up in the center of the bed, and they yanked out a chunk partway through the print. I...

    That very well could be. The one really critical adjustment is the Z height, and if that drifts, printing will suffer considerably. Using auto bed leveling mostly solves that problem.

    I say...

    Check that the bottoms of the Z screws are flat and file them flat if they're not. The axes are always a little misaligned, and when the non-flat cut surface rotates with the motor shaft, it rises...

    I've been tweaking my Makerfarm printers for a while, and I'm getting great results. I have several coworkers, also with MakerFarm printers, who are not at all happy. I don't really think there's a...

    I'm very interested in having something like this. I have a fork of the beckdac fork with customized branches for my double extruder on various MakerFarm printers. I'd really like to get out of...

    You're welcome.

    I run all of my printers with used HP DPS-600PB server power supplies. I power a Raspberry Pi, the RAMPS board (VCC) and the RAMPS servo bus (+5V) direct from the 5VSB on the...

    I have seen situations where the current draw of the probe servo causes the Ardunio to reset. This could get you different results between the host program and the SD card because the SD...

    They don't have to be exactly 27mm. You can calibrate the actual distance in software.

    You can do it in Marlin, but I find it easier to manage in the slicer. I've done it in Slic3r and in...

    Most slicers that support dual extrusion have this option. It definitely helps, at the expense of print speed.

    It's possible. Wiping will help, but not if the nozzle keeps oozing.

    I have been thinking about retracting the hot ends for a while. The video below didn't work for me, so I'm not sure what it shows. [Edit: Ahh...beerdart, so this is the spring-loaded hollow-bolt...

    I believe the existing extruders will fit the Pegasus. The X axis extrusion spacing is the same, so you would need to print the X axis backing plate and mount the wheels and everything else to that,...

    Yes, that's a lot better. It still looks a little overextruded to me. Here's an example of one I pulled out of my scrap box:

    This one is definitely underextruded. I think it was printed...

    Gary,

    I get the best results with two identical hot ends. If you're trying to mix and match, you can probably make it work, but you're making it harder on yourself. I find that the same filament...
