Re: How-to: Dimensional Accuracy Calibration for Delta Printers

GeckoTek won't be flatter than glass. There are tiny undulations on the surface. I got sick of how easily the plates get scratched and have taken to clamping the glass disc to the GeckoTek aluminum base, as it works very well as a heat spreader.

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

If you're using a 0.5mm SeeMe nozzle, I recommend setting extrusion width to 0.55. You may measure that it's less than that, but that could be due to contraction from cooling. It's usually not a good idea to use any value even slightly less than the nozzle diameter. If you do, you may see weird arti...

Hi, I know this is old, but 626pilot could you please port your code to a newer edge realease. Last year it was a major update regarding very small movement parsing and hangs which my S3D seems to generate.

They shipped one to mhackney and he said that it worked very well, and that he expected it to hold up over time.

Re: Hectic! But nice.

nope. still waiting, looks like they are making a lot of compromises, so we'll see. From what i read they changed to a different sls printer whose tolerances weren't as tight, but they are adding a bushing or something to get rid of the wobble. I got an email about this a week or two ago. Having de...

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

Consider that a 50x50mm solid box has 122 times more XY area than one side of a single-walled 50x50mm box. I would expect to see more positional errors pile up given the increase in area. In Delta printers, there is generally more positional error between two points the further they are from each ot...

Re: Effects of microstepping and segmentation on print qualty

Well, this is a significant find. I always thought Moire patterns were a necessary artifact of using Delta printers, and you could only eliminate them with some crazy high-res steppers. You've really got something here.

Re: Effects of microstepping and segmentation on print qualty

Setting the layer height to a multiple of the golden ratio (once you figure out how much distance a full step takes) spreads the peaks out enough that they stop being visible. Based on Bruce's last few prints, it looks like the Golden Ratio idea works pretty well. I see only straight lines, with li...

Re: Effects of microstepping and segmentation on print qualty

The Golden Ratio idea is really cool! To reduce these artifacts, I recommend upgrading to 400-step motors (0.9 degrees/step) and upgrading to a 32-bit controller with better drivers. Smoothieboard and Duet both offer that. I've used both, and while they have different step generation algorithms, I c...

Re: New with a pile of parts

I got an acrylic MAX v1 in December 2012, and I can confirm that the acrylic likes to split! SeeMeCNC was kind enough to send me some replacement parts when this happened. Unfortunately, even if carefully assembled, the top plate can develop cracks after awhile, and it looks like yours has already d...

Re: CAD designer recommendations...

With the caveat that I haven't done work for injection molding (which I assume is what she wants), show her this and let me know if she's interested. If it's just for a mock-up, I might be able to do it. If needed, I can print samples on my Form 2 in whatever resin she wants. New Effector (F360).jpg

Will this board have a dedicated header for the PanelDue, or will it be plugging in one wire here and another there? I didn't use the PanelDue for very long, but I thought it was great.

Re: injection mold machine

Formlabs' high-temp resin is rated for 289C at 0.45MPa. I wonder how it would stand up to thousands of shots of ABS. According to this, it is recommended for injection molding, and also not recommended for injection molding!

Re: LokBuild - wow - update not so wow after all.

SeeMeCNC's Ultralex is pretty good for PLA. GeckoTek is good for PLA, ABS, PETG, TPU, and nylon (requires different surface) - but it scratches very easily, and a new disc is ridiculously expensive. Kapton tape is cheaper. Glue on glass is very easy, and once cleaned, the glass is the best surface f...

Re: Trick Laser MAX METAL Build

That thought had crossed my mind. IM is an option for a mature product (doesn't need any design changes) with enough market to justify producing 100s or 1000s at a time. Getting the molds cut for something like that would cost somewhere in the five-figure range, if I'm not mistaken, plus whatever th...

So if you're interested in sharing the design at this point pilot, I could design a set of setups to do it on a standard 3 axis machine. The machine only has 5" of Z, and the part would have to be mounted at a 45-degree angle, so it could be tight. Also, my driver box isn't talking to the comp...

Re: Trick Laser MAX METAL Build

They wanted over $400 to do a very basic version with no trim, and over $600 to do the "ornate" version you see here. That's just for bare aluminum. It was still more to get it anodized. Unless I want to sell printer parts exclusively to rich people, it just wouldn't make sense. I still wa...

Re: Trick Laser MAX METAL Build

Looks like the 5-axis idea is out of the question. The site I was using to get a quote has an idiosyncrasy that can make you think you're getting the price for machined 6061 aluminum, when you're actually getting the price for sintered nylon. 5-axis machining is too expensive for this, for the time ...

Re: Why?

They should add options to leave out things like the controller, motors, power supply, and hot end. This would be pretty great for a backup printer, but like mhackney says, I don't use 1.8-degree motors anymore, and I'd rather bring my own controller and hot end.
