In the process of gathering the materials to test an air pump with a tube ring. Slow going. But it does bring me to wonder if anybody has done some real research into the cooling requirements. I have seen solutions where there is a virtual tornado going on and versions where there is no more that a trickle of air going. Both solutions were praised by the users as being perfect. What is the realiby Lykle - General
I bought the Spitfire. It will fit a Prusa i3 print bed. It comes with prebuilt S3D Factory files etc etc. Really complete. It is a fun project and my Spitfire has a wingspan of 90 cm or so, so it is big too. Love doing this. Still not sure if I am going to make it fly or just use it as a static model, but it really looks good either way. Lykleby Lykle - General
Just became a Grandfather and now this! What a year ending this it turning out to be. Congrats!by Lykle - Delta Machines
Hmm, might work. There might be some variation between the two, depending on the field of sensing. The heater block is different in size, that might influence the sensor. But overall, yes that should work. The tips of the nozzles for the Volcano and V6 are shaped the same, so that would help keeping things consistent. I like the idea.by Lykle - General
For future reference, if you need V-slot profiles etc in Europe, try Ratrig.com Based in Portugal I think. They supplied me with profiles and seem to be on the ball.by Lykle - Delta Machines
It can't be the belts, as the skew happens all over the bed, so the belts are in different positions all the time. I like the idea of mechanically checking the effector as it moves in height. Because that answers the question if it is the hot end of the effector. Next thing to try is disconnect everything and only check movement. With an empty effector. In the end, as it is universal and lookiby Lykle - Delta Machines
I am working on a 3 filament extruder using the standard components of the Nimble, in case you are interested. But I really like the idea how these extruders are mounted. Clever. Lykleby Lykle - Delta Machines
For an extruder you could use a RDD extruder (Remote Direct Drive). This combines the all the good points of a direct drive and a bowden drive, with none (almost) of the disadvantages. For instance, the Zesty Nimble or the Flex3drive. (PSA I am one of the creators of the Nimble) They work by splitting the power and the drive function, so the stepper is mounted on the frame and a drive cable tranby Lykle - Delta Machines
You are not using the grid leveling system, correct? You had switched back to previous version of RRF if I recall correctly. As I was thinking if it was an error in the grid system, that tapered off over Z that would explain it. Can you print a large diameter cylinder wall? As large as will fit. You will have to go above the 50mm just to be sure. Would be interesting to see if the slant is conby Lykle - Delta Machines
If it is the stepper it is strange that it stops at 50mm. So basically you will have to print everything with a 50mm tall brim? (sorry) Does the -X direction slant confirm cabling as the fault? Is the cabling bending in that direction? If it was the wobbly hot end, you would expect it to fade not simply stop at 50. Also, what happens if you go higher? If it is the wobbly hot end, it should retby Lykle - Delta Machines
I don't see the conclusion of analysing the gcode. But I assume the gcode is for a straight print. So the slant starts at a certain height and ends at another? Is this fixed? Meaning is it always the same height where it starts, regardless of where on the bed you are printing or the size of the object your are printing? You ruled out firmware, I think you have ruled out slicer, so it must be meby Lykle - Delta Machines
It is great that it works now. Good collaborative effort. But what was the real fix? Was it the new gear set or the acceleration (amax) settings?by Lykle - General
Yep, compliments to Sanjay.by Lykle - General
OK, so you are using a direct drive and a V6. What is the retraction you are using? Should be around 1 mm, maybe 2. What is the fan on the hot end doing? Is it full speed? Are you sure? Is it blowing or sucking? Have you installed the hot end as per E3D instructions? Heat up the heat block before tightening the nozzle, etc? How did the PLA work? Lykleby Lykle - General
Yeah, had a look at that. I feel for the guy, he really tried hard and is failing. The problem with that situations is that all you are paying for, is the debt. That is what he needs to money for. He is doing the right thing by insisting that all the debts are paid. Honorable man. I have been in that situation and it is tough.

The bumpers should be easy to remove, I recycle printers all the time. Just slice them off. Also you can slide them off but that takes force. Usually the rods are nice and straight and smooth. The coating on the rods is an issue yes, It might be able to dissolve it, try acetone or thinner. I would not sand them down. But to use these rods for printer movement? They usually are relatively sofby Lykle - General
I love how in the square version, you can print on any surface. You can place it on any flat surface and print something. With good calibration, you could print an object straight onto the roof of a car, for instance. Mount it with sucker feet, calibrate and print a new air scoop. Magic! I need to start experimenting with one. Man you do good work! Lykleby Lykle - Look what I made!
Yes there is no issue there. They can be touching, overlapping or not, does not matter. Check out Shapeways.comby Lykle - General
No,injection molding is not the way to go for you. What is the total number of units you will need? Only when you say more than 10.000 units will inj molding be relevant. One way to do it is to use SLS (laser sintering), for instance Shapeways does it with the Strong and Flexible materials. Lykleby Lykle - General
Thanks James. We will get there. Just by a different route. Lykleby Lykle - General
Well, that was a pity, the Kickstarter campaign did not reach the goal. So we went to plan B. All the critical parts are custom made and the body is going to be made using SLS. This allows us to be a little bit more flexible in the production of the units and gives a little more freedom in the shaping of it. Attached is a top view of the current body of the Nimble. It might also mean we will bby Lykle - General
One way to make the most out of the aluminium tubing is to fill it. Filling a tube with polyurethane foam, makes for a very stiff and strong tube. You can even tweak the stiffness by using different grades of urethane. I stiffened up my race car chassis by filling it up with foam. Added a lot more stiffness and only a little weight.by Lykle - General

Might be a z conversion issue. Perhaps working in metric but the z axis is in inches? Sounds stupid but it does show up like these kind of cuts. It also depends on the printer you have, so more details please. lykleby Lykle - General
I love the idea! Maybe a ring shaped groove around the circumference would be enough? If the vacuum is strong enough it would pull the top film tight. Especially is the groove is deep enough to handle the material sagging into it. Depends on the top material of course. I certainly will be following this with interest. Lykleby Lykle - General
I agree, E3D is doing a great job keeping that balance right. Great admiration for them for being able to do that. Lykleby Lykle - General
Talking about a female body, I had a torso I modeled a while ago. Decided to see how smooth I can print it. There is the link to the photo's Hesitant to show more because of the nature of the object in the images. Lykleby Lykle - General
Alternatively, you could go for a Remote Direct Drive. Leave the stepper on the frame and power the extruder with a drive cable.by Lykle - General
You could try faberdashery. But they do not make rainbow filament on a spool. You get 10x10 meters of different colours so you are responsible for switching the colours.by Lykle - General
