Re: Core XY Printer £100.00 Build Cost
Hi Len So far only PrntQB 1 and 2 are published. I'm working, slowly, on a core xy that uses Openbuilds V wheels but it's a way off yet. The Cherry Pi range of deltas are mine too and CP III uses v...

I'll look at the carriage, seems straight but maybe it's not. Since I've swapped the arms from one side to the others and its stay the same way, the carriage is the only thing left to look. I also...

I'm calibrating my Kossel for the first time right now... :) Anyway, I was thinking you could double the print height of a Delta by switching the orientation of the arms half way through the print....

Longer extrusions (and more bracing) are probably cheaper in the long run.....

I have the same problem, when I print a object X40mm Y40mm Z50mm height the XY dimensions or correct but the height is bad. I measure Z53mm when the print is ready :S I change the steps\mm of the z...

That would be some pretty complicated switching. The arms aren't designed to flip up loosely like that. You would need pretty decent force from some motor to do that, adding more weight to the...
View ArticleRe: Kossel - all axes calibrated, but height is wrong
Print a cone with bottom radius of about 1 cm and top radius about 0.5 cm. Make it about 5 cm high. Measure the height with callipers. If the height is not correct then your steps per mm are wrong....

I can't see how it is possible without disconnecting the arms and re-attaching them.

If you did not buy belts yet, get ones with carbon fibre or steal core. Kevlar may be ok if you can get the better one (there seem to be more variants). Avoid glass core belts. They are too stretchy....

Not only that. How about arms colliding with the printed piece. If you would make the platform so wide that this would not be a problem than more space would be wasted by making the printer more wide...
