Re: Xnaron Printable Magnetic u-joint option for Rostock Max

Weird - I'll have to check - I was holding one of your parts up to xnaron's effector, and the holes didn't quite seem to line up. It was close - within a mm or two. I like your cheapskate mount better since it's got holes for the end stop on both sides - geneb's guide has you installing the bracket...

Thanks. I am picking up some to try.

Re: PEI print bed surface experiments

How is this stuff holding up after numerous prints? Still holds just as good as day one? Does it damage fairly easily?

Gentlemen. Grease your balls! Now that sounds awkward. ;) I have a lot of time on the mag arms and I wanted to mention that putting a small amount of vaseline on each ball will really help to smooth out movement and reduce friction. I am still on my first set of arms and I can see no visible wear an...

Re: Xnaron Printable Magnetic u-joint option for Rostock Max

I am looking for someone who completed the Xnaron arms and used the geared stepper motor for the extruder. Specifically I am looking for the steps per mm that you used to drive the geared stepper. Thanks to anyone who would be able to share the number that they used. It depends if you are using the...

Re: PEI print bed surface experiments

Interesting stuff! Has anyone tried thicker sheets (1/8") and just clipping it to the pcb and not using the glass at all? I have no idea how hard this stuff is as I haven't seen it in person.

for .9 degrees steppers, should you buy unipolar stepper or bipollar ? what voltage ?

No. I am running a geared stepper. I do want to try a 0.9 on a wades variant. I need to pick up a hobbed gear though before I can do that.

Re: Vertical Banding Issue

An added benefit of the 0.9 steppers is that they are quieter than the 1.8 steppers. I didn't install the noise dampers with these. I think there is a slight quality penalty with them on so I opted to leave them off. I was concerned about going back to the noise as they really made it quiet. It was ...

Re: Vertical Banding Issue

Wow, that's a lot of advancement! I'd love to see the pics of the setup. So, it seems like more processing power helps but doesn't eliminate. Perhaps the culprit is the algorithm? cheers, Michael I'll make a youtube video tomorrow of the setup. So for the results I'd say cylinders are on par with a...

Re: Vertical Banding Issue

I'm playing with different values for the printing segments. I tried 400 and it isn't as nice as 180 (default) was. I tried 800 and ended up with some stuttering. I tried setting it for 70 and I think it may actually look better. This is on a cylinder printed as a vase. I still need to do a lot more...

Re: Vertical Banding Issue

I've got the 0.9 steppers installed along with the ramps-fd running the ARM Arduino DUE. I just finished a test print with the printer. I used the same repetier config. The vertical banding is definitely still there but a lot fainter. It is closer to the banding I have on my cartesians. I need to ru...

Re: Vertical Banding Issue

This problem is caused by the stepper motors. 626Pilot got it right with the image on his post. The only difference is that the blocks would have smoother edges. #define PULLEY_DIAMETER 10 #define PULLEY_CIRCUMFERENCE (PULLEY_DIAMETER * 3.1415927) #define STEPS_PER_ROTATION 200 #define MICRO_STEPS ...

Re: Vertical Banding Issue

My Ramps-FD got here... but as bad luck would have it they neglected to ship the arduino due arm board with it. I ordered another one from a closer source and it should be here soon. I was looking at some older prints today and I noticed the vertical banding was less visible. I think these prints we...

Re: Vertical Banding Issue

Now, I wonder what a delta segment is? If you are printing at 50mm/s does this mean that 50mm/s divided by 180 segments/s yields .278mm - that's actually pretty big. I think we are on to something. I've wondered about this for over half a year. What we are probably seeing is either pulsing from the...

Re: Vertical Banding Issue

Now that I'm looking for this, I am seeing vertical banding everywhere - even on cartesian printers: check out the purple box made on a Makerbot. Yes I can see it very very faintly on my cartesian prints. It is so faint it is barely noticeable. Certainly not as bad as what you pictured in that link...

Re: Vertical Banding Issue

I think you may have surfaced a systemic problem. Take a look at this photo: from the kickstarted OpenBeam Kossel Pro. That sure looks similar. I'm going to peruse the web for other delta prints and see if a pattern emerges. Yes :( It has been bugging me for over a year. I feel a little better know...
