Re: Rotating Ball-Screw nuts

Here's an XY flexure. Might try building something like this m'self.

Re: Rotating Ball-Screw nuts

It seems like it would also be possible to design a printed flex-joint that allows translation but not rotation. This is super-crude, but something like this (with one additional degree of freedom):

Thanks for posting this. I've had as many fails with ASA as I've had failures.

Where do you get your ASA?

Impressive prints. Did you print the bolt and nut just to try that out? I always try to use the real fasteners when possible.

Re: Easy printing, high-temp material

I've used MR16 halogen bulbs on a dimmer to keep the print warm and prevent warp. On the Makerbot this was super easy because there's a huge area around the print.

I went looking for low-warp ABS and it sure seems expensive. I would definitely be interested in US-based low-warp ABS around $30/Kg.

Weight of N2 or N2+ dual extruder assembly?

Hey all, I'm working on my N2+, and want to simulate something. If you have weighed the dual extruder assembly from an N2 or N2+, how heavy is it?

Re: ABS warping

I've been using ABS slurry for years on my old Makerbot, and recently started using it again with my N2+. Works surprisingly well. I definitely prefer it to BuildTak and PEI sheets.

Re: Anyone have a spool of Raise3D Premium Red? / Restock time?

Are you in the US? I have two partial rolls of Raise3D Red premium PLA that have been sitting out for a while. Probably need drying. Probably about a kilo in total. You can have them for $5/ea plus cost of shipping - but I'm going to take them to some full-service mailbox place because I don't have ...

Re: Spiral print rough on one side

I had a symptom like this in some large prints. The problem turned out to be that the "rough" side was not getting enough air from the cooling fan(s). Try to visualize that side of the print. Does the fan dwell on that area as much as it does the other areas?

If you want details on the extruded, just go to http://shop.bondtech.se/en/upgrade-kits/raise3d/raise3d-dualdirect-upgrade.html. I just installed this on my N2 Plus a few weeks ago. I’m fairly certain that Raise3D is using this specific extruder. It looks identical to the one in the Pro2 photos Tha...

Congratulations, Raise3D. Personally, I'm most interested in seeing sample prints, and in more technical detail about the extruder. I'd also be curious about the long-term availability of the current models. As someone who recently left a corporate environment, I can see the need for a "service...

Re: How fast Do you print? And how fast Can one print?

I print a lot of very large parts, so I've tried to push speed in ways similar to zemlin. The main thing that I've noticed is that over 60mm/s in any material, the prints become noticeably more fragile. Printing slower than 60mm/s definitely improves strength for me.

Re: motor connectors glued in place?!?

The use of hot melt, silicone, and other adhesives to secure connectors is an industry-wide best practice for electronic devices. Devices like these printers are subjected to significant vibration during the shipping process. During normal use, the printer vibrates itself. During handling, repairs, ...

Re: Improvements by using TMC2130 driver.

Great work ABH and thanks, Trinamic, for weighing in.

I have what might be a stupid question. Are the silentstepsticks that Trinamic linked drop-in replacements for the existing Raise3D stepper drivers?

I saw the same thing with a piece of glass painted black, measured with a thermal camera, Casel8 is right, I set my bed to 108C to hit a desired temp of 100C. There is a +/- 5 deg C variation across the bed.
