Re: Open Source Syringe Pump

Have you made any more progress on this? How was the torque?

I'm curious if using a gear setup like wade's extruder would be a better system for more torque. Maybe just one of those geared nema 17's? Thoughts?

Re: PLA bed leveling trick (and a question)

I've tried prototype supply (esun) and form futura. Same problem with both, failure rate is pretty high (smashes bed way down unless I manually scrub the thing). I have noticed that I'm manually heating up to about 200c to scrub but the default cleaning is much lower. I wonder if that is the culprit...

PLA bed leveling trick (and a question)

I've been putting this mini through its paces this weekend. I haven't had a single print failure yet! They're all gorgeous and the new bed material is friggin fantastic. The bed leveling is really buggy for me though and I think I've figured out why. As many have noted, if you're using PLA, the bed ...

Re: Open Source Syringe Pump

I can see you've made some updates to the design. I'm thinking of giving this a try but I've got a few questions.

1) how torqy is it? could I push a ceramic through it?
2) Have you played with any slic3r configs yet?

Re: 2D printing: it's cooler than it sounds

You beat me here! Yep, I loved this. Even though I've actually got a 32 inch plotter sitting a few feet a way, I wanted to do it with my printer! I made a quick snap-on holder because I thought I might want to try a few larger markers as well. It turned out ok! If you've got any lulzbot printer, my ...

Quick paste extruder... the wrong way

Before I share this rediculous hack, I'd like to point out that the proper way to do paste extrusion is being done in another thread. that being said, I don't want that whole mess. I want a print head I can toss on, like I do with my flexistruder, that just takes a single syringe so I can screw arou...

Re: Help refining the A0-100

I have upgraded the following from stock: - x carriage - z axis stepper mounts - x endclamps - smaller gears (and updated code) - filament tube mount - Z endstop mount - box fan pointing at it. The difference is considerable. I actually printed a part where the little nut actually fit in the nut sha...

Re: Help refining the A0-100

Thanks for all the great ideas to pursue.
I've already got the smaller pulleys.

I'm printing the new X endclamps now. If I recall correctly they bump against the brackets that mount the steppers to the threaded rod right?

I'll also print the tensioners and come back after all that.

Re: Help refining the A0-100

I have no idea if this is important or not, but with the .25 nozzle my layers end up with all these little rough bits. like this (right click and choose "view image") http://i.imgur.com/bF3ATqn.jpg pardon my dirty print bed, I'm doing test after test and it is a pain to get totally clean.

Hi!

It has been quite helpful. Since I've had this I've had a few annoying issues t...
