Welcome to the SeeMeCNC Community

I just launched a kickstarter project of special interest to all Delta printer enthusiasts. Its a single low cost linear module that is designed for both cartesian and Delta configurations, using a precision aluminum extrusion for housing/guide/motor mount/carriage. Its motion is driven by precision...

There is an essential problem with tiny variations in arm lengths, connectors, which is almost unavoidable with sanding the parts to fit. The geometry of two parallel arms is intuitively great, and variations tend to get averaged out in the center of the printer. However, the "worst" place...

Hey, thanks for the G100 code guide! I'm going to try it once i get a chance tonight. I am new to the rostock community, as i recently built my first V2 about a week ago. After some calibration, the prints were putting the makerbot i previously used to shame! I'm not too sure what i did, perhaps it...

Greetings, Rambo seemed a good starting point for a new CNC machine (skipping boring part) and I needed to mount them in a card slot. The "Standard" Rambo card has connectors which stick past the edge on 3 sides, so eventually I had some custom built. I had to buy quite a few to get a dece...

Oh thank you so much guys!!!!! That's great news doing the calibration now. thank you again!!! Anthony fyi there is a micro step constant in configuation.h now, it can be set lower than 16, in powers of 2. 8 4 2 and 1 ======= Which should not imply I know what microstepping actually does or why one...

I do not know. As I said I'm not the author, and am only aware it is out there. As earlier posts I have made said, the software is not capable of correcting some of the hardware issues, even the newest cannot deal with imperfect parallelogram arms. https://github.com/mrbi11/Repetier-Firmware" ...

I have NEVER seen a working auto-calibration for deltas outside work that's been done to a recent branch of Marlin. And yes, we're talking about the same thing - when the Z probe is used to touch a number of spots on the print surface. I'm not giving "misinformation" about anything. Also,...

Not sure if we are talking about the same thing. I am referring to z-probe calibration. It is not automatic. You have to manually indicate contact by clicking a switch. (or by having an actual z-probe hookup) The author of repetier-firmware uses this for his delta, so fairly sure it is only for delt...

If you have a bare spot one side and loose on the other, the long arms are different lengths (don't have a fix) This seems to be my problem, can software correct it? Thanks[/quote] Forgot to answer this part. The software only has a single number for rod length, so cannot help. For my system I remo...

The latest repetier-firmware version has some calibration driven by "z-probing", which amounts to indicating when the head touches the surface at multiple points. (1.9x). I believe that will get your printer as close as currently possible via software alone. However, I believe most issues ...

Oh, I forgot some stuff. There are some un-calibratable errors you should check for with your hardware. Using a carpenter square, double check the square on all towers. Not just kinda, but as close as you can get. Square to the print bed. Ignore the roof. If you have to adjust it, remember to take t...

I have problems with the bed leveling outside the triangle. Are there any solutions for that? Like auto bed leveling with more then 4 points? Well someone besides me is printing where dragons be. Short answer is the older versions of software assume perfect physical geometry, and so no its not poss...

Hi, I posted a reply about generic stuff with line trimmer, and it made me finally try it myself. What your picture looks like, is what my first print looked like, and that is your nylon needs to be dried out. My first print went snap crackle and smoked. Search the forum about drying nylon. I put my...

Found one. Thanks!
Gonna go cook my nylon

Maybe just set it on broil and speed it up

I have posted a bit about printing outside the triangle, near circles edge. A lot of stuff changes there, some of which is fixable, some not so much. Mainly inside the center triangle (all rods pointed in) errors in measurement are minimized by the geometry. Outside the errors in measurement are mul...

I finally took the plunge to try nylon. Specifically I am trying the blue weedeater nylon, the brand recommended elsewhere on this forum from Amazon. Some good stuff, it doesn't flake off even when its jammed, like my abs does. Not so good, there seems to be a delay from starting the extruder till i...

1.75mm isn't always 1.75mm. In the case of trimmer line, it is actually .065" Which is 1.65mm. In order to get good print results, you need to measure every spool of filament and enter your measured value your slicer program. Otherwise, you're going to over or under extrude I concur. You guys ...

On diameter question, I'm not really clear what that can possibly have to do with anything. Does 1.75mm abs work better or worse than 3mm abs? Of course, your slicer has to have the matching diameter to compute goo volume, but I tend to assume people have read the instructions. So, what does filamen...

I am working on a post for it, but there just aren't enough hours in the day right now. I have an E3D, and when I print with it, my retraction is at 12mm @80mm/s For that print, I would try printing a little cooler... 250-255C If your filament isn't totally dry, stringing is unavoidable. Filament d...

Any ideas to fine tune this? It seems like the diameter of the trimmer line is keeping the print from better results. image.jpg basically I'm the other new guy so take this with a grain of salt. I believe the diameter of the filament does not matter. The diameter of your nozzle might be a factor. I...

A "How to" for printing with Nylon would be helpful, like the one you did for ABS.
If you are in the mood to teach.

Honestly I am not that sure of the temp measurement. I used an IR gun type, and used it on the glass. When I pointed it at the bare shiny aluminum it read room temperature-ish. Science thing i guess. I have an accurate thermo-meter for it, but no reason to go to the extra trouble. The edges of mine ...

CJGerard, I checked around and this warping is a known issue with certain Al alloys in thinner thicknesses. If you are simply clamping the Al with binder clamps, why use such thick aluminum plate? If you are going to put borosilicate over the top, I'd recommend using a thinner Al plate, even 1/16&q...

No, I just set it on top of the heater. I had to get some larger clips to hold the glass down, and they also hold the aluminum. It would be pretty easy to use the insulator that hols up the heater plate or the plate itself as a template to mark drill holes if you feel you want them. I could not see ...
