Re: Grounded Experimental Delta Printer
I will answer the question, but it's important to set the stage properly. Gen7 electronics are not fancy. In fact, they're about the polar opposite of fancy. They are cost-reduced and...

The buildvolume for all options is about the same. But why ditch the Kossel/Rostock? I'm building the Rostock Mini but it can easily be scaled to as big as you want. Some have made it 150cm tall. Even...

Thanks for such an epic answer. You have been putting lots of energy into helping us out. You seem to be the one to ask. How can I implement a webcam on the end effector for ontactless transducing. I...
View ArticleRe: Deltas: Kossel versus Rostock MAX versus Cerberus versus Kossel
The rostock bed is entirely static, so what in the design do you really need to be able to put one on? Just sandwich a heater of your choise and call it a day. I built my mini Kossel to 300mm x 250mm...

Just to say thank you to your answer (to both of you). I think i will go for a gen 7 card. (But not immediatly ^^') I will continue to read this post. Thank you very much for this great design, I will...

Mounting a webcam on the end of the efector will be challenging. Not physically, but isolating it from something hot. It's also going to be a challenge in terms of cabling. A USB cable going through...

I don't need perfection. I just need a bunch of data so I can use machine learning to solve for the optimum set of calibration values. I won't use it all the time because any one pic from the camera...

Thanks for the explanation Annirak, it's very helpful. I'm now going to spend some quality time with Google making sure I actually understand it all :)

What heat issues with the Max? I just bought my kit a few weeks ago and got it up and running. Extruder is great, but if you haven't used a Bowden before it'll take some time to figure it out. The bed...

I was planning on shielding but I am definitely out of my element here. I will probably test with a standard cord. To be honest, I didn't see that the high flex one was $10. That is not bad. Best idea...

A shielded USB cable should hold up as long as you're not putting it through too sharp a bend radius. One alternative you might consider is an IR LED on the end effector, and two webcams at 90 degrees...

I like where you are going but it doesn't allow the table to be warped.

Not sure what you are trying to do with a webcam, but if you start to use IR LED, you may use wii remote controler. This guy:[www.youtube.com] made a very good tracking of IR led, and he say that you...

My current plan is to print out a pattern and place it on the bed. I will temporarily mount a webcam on the effector and then go through a calibration routine that gathers at least 1000 data points. I...

It sounds as though the goal is to produce a map of the height of the printbed, rather than assuming it's flat and simply measuring its tilt. If that's the case, wouldn't it be necessary to print the...
