Re: Grounded Experimental Delta Printer
All is going well. I have had two hangups. I don't have a printer that can print the arms as-is in PLA and my CNC mill had some serious y-drift. I fixed the mill and am redesigning the arms so they...

Hi thanks for the replies, I can get PLA to stick ok initially, it's stopping the stuff lifting mid print (even with brims) that’s the main problem. Haven't tried hairspray with PLA yet, I was using...

How hot are you running your bed during a print? 80C is probably too hot for PLA.

I'm willing to bet that there are folks on the beta list, including at least me, who would be happy to print the parts for either machine ourselves in order to help you out and accelerate the process....

I print on 60 degree glass and 60 degree kapton with PLA and hair spray. Verify that you have VA/Crotonates/Vinyl Neodecanoate Copolymer in your hairspray. It seems like every country has only 1 major...

I do want to enable others to print their own. Here is the issue, I am not charging for my labor on these beta machines so I wouldn't be able to charge the testers a reduced price for the...

The intellectual labor you've put into this is staggering, and just about unimaginable to someone like me who can't even visualize how these linkages work until they're designed (and sometimes it's...

To get rid of the spring you could also replace the strings of the DLCJ with flexible blades , I have used such kind of self deploying articulations in the past [www.casimages.com]]

Thanks for getting back to me! I will try the motor swapping for the X/Y direction fix but first I will try simulating a print to see if its a problem. I'll do all the test with the extruder, I don't...

Nicope> Clever idea, it reminds me of the Rolamite bearing. Were you able to adjust the tension of the ribbon? Thanks for sharing. A2

Here is how I would do the blades. You need 3 so you can balance the tension. I did some super quick sourcing and I could get the raw material for each individual blade for 25 cents. (You will need to...

Double lamina compliant joint (DLCJ). I believe that the hinge that you and Nicope have drawn up has another name, and I'm unable to find a picture to help my memory. This joint is often assumed to be...
