Has anyone done a 32bit upgrade to the N2 series?

Since my LCD is bad and my speed in printing seems to be limited to the 8-bit motion board, I'm thinking it may be about time to scrap the R3D electronics and go 32-bit. There are now some very inexpensive 32-bit boards. Has anyone else thought about this or, better yet, done it?

Re: What killed my touch screen

I just got off the phone with TS and they tell me I need a new touch controller. That will cost about $450. So, I'll use my mouse and/or wireless control for now. I can buy an entire CoreXY printer for $450!

This might be a good time to do the 32bit upgrade and scrap the R3D interface.

Re: Taulman 910 warping

I had this same problem and finally did what Taulman suggests to do: Print directly on glass using PVA. I could not get it to work on the Buildtak no matter how much i tried. I set build plate to 45C and let the chamber warm up thoroughly. Extruder was set to 245C. Lastly, don't try to print fast wi...

What killed my touch screen

My printer has been sitting unused since about last May or June. I turned it on yesterday and let the battery charge overnight. When I tried to print I found that the left upper section of the LCD screen does not respond to touch. The rest does. So, for example, I cannot set the extrusion temp direc...

Re: Berd-Air -- no voltage to HE2 pin

Thanks Ari. Well it looks like i was mistaken again. The assembly is just much quieter and is running below 100 . I found this out while playing with the tuning while the printer was not printing -- so it was easier to hear the motor running. Prior to adding the diode and capacitor, it was significa...

Re: Berd-Air -- no voltage to HE2 pin

Ari, I added the capacitor and the diode as described. Now the Berd Air will only run if the power is 100%. Is this some side effect of adding the components?

How is your BerdAir system doing?

Re: Realities of printing with the Mosaic Palette 2 Pro

Thanks for the video, it's a great help for us newbies! How hard is it to purge the hot end to avoid color issues? You don't purge the hot end yourself. The software does it. I have tried different lengths of filament to completely get the color out of the nozzle and a conservative amount is 130mm ...

Realities of printing with the Mosaic Palette 2 Pro

IMO the Mosaic Palette 2 Pro is a giant leap forward from the Mosaic Palette. For me it has preformed without issue using PLA and PLA+. I'll soon try some ASA and see how that goes. In the video I state that the time to print the object being printed will take 13 hours. It actually took 9 despite th...

Not at this time. I was hoping to be able to make a kit to speed up the N2's. Still working on it.

Re: How I more than doubled my print speed while increasing accuracy

Thanks for the update. Wouldn't have expected the bushings to sing. Interesting. If lube is critical something I've done in the past (not on 3D printers) is use heavy felt to retain/distribute oil. Something like a 2mm thick felt washer on each side of the gantry block would keep he shafts lubricat...

Re: How I more than doubled my print speed while increasing accuracy

Time for a short followup to this post. At this time I am calling this project a FAIL. The reason is simple. The linear bearings, which are holding a very tight tolerance on the cross rods, sets up a resonance frequency with the 8mm steel travel rods. The frequency varies with the distance the print...

Re: How I more than doubled my print speed while increasing accuracy

I have discovered a problem with my new ultralight print head: I cannot add a second E3D because they screw into the printhead. I have been printing very successfully with one printhead and wanted to try two. Before I even went to try to add the second hot end I realized that I would not be able to ...

Re: Berd-Air -- no voltage to HE2 pin

It appears I have been chasing a red herring and involving you in my machinations. I do apologize. I just loaded the same firmware I have been running in my N2 (that does not work) into my N2 that was working. Now it does not work. That is, the 24v pin does not get power. So, it must be that I have ...

Re: Berd-Air -- no voltage to HE2 pin

Thanks again Ari. Really nice instructions. Regarding the 24v pin: I made the two measurements and they are 99.8K Ohms and about 14.5M Ohms. So both good. I solved my X axis problem. Don't ask how! I unplugged the connection at the Y motor and plugged that into the X motor and the X axis worked. So ...

Re: Berd-Air -- no voltage to HE2 pin

I measured the resistor at 0 ohms and the 24v rail was at 24v. So both appear to be good. I now have another problem: The X motion of the gantry is in a state of constant skip when I try to home it -- so sounds like a jack hammer. If I press the right arrow on the LCD it will go right a little while...

Re: Berd-Air -- no voltage to HE2 pin

Ari, Thank you for the full instructions. You know, you keep talking about 12V and I keep thinking, "But don't I have a 24v pump motor?" I checked, and yes I do. Both pump motors are 24v. I got those based on connecting to the HE2 pins. JetGuy is the one who said it was okay to do this -- ...

Re: Berd-Air -- no voltage to HE2 pin

Ari, Thank you for responding. The LED does not come on when I command the fan to run via HE2. I don't know of any other 12v outputs not working. That is, my extruder fan and motion board fans are running. I don't have a map of the board to know what pin outs are also regulated by the same 12v regul...

When I bought my N2s a camera was one of the items mentioned as being part of the purchase. Is Raise3D going to make good on delivering these cameras? Do you mean the camera option for Kickstarter campaign? No. When I bought my printers you were still advertising that it came with a camera. I was d...
