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: Berd-Air -- no voltage to HE2 pin

I will be glad to help in any way I can. What do you plan to attach the 12v pump to?

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...

Re: what happened to the the Official Raise3d Camera?

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...

Berd-Air -- no voltage to HE2 pin

I have Berd-Air pumps running on 2 N2s. They use the same firmware and have been running just fine until today. One of my N2s no longer pumps air. I checked the voltage from the pins at the motion controller board and I get 0 vdc at 100% on. What would cause the voltage at HE2 to drop to 0?

Re: Best upgrade (nozzle/extruder) for N1 Dual-head printer

Yes. Get the Bondtech. You will make better prints faster. Get the dual head if you use both nozzles, otherwise get the single. Just depends on what you do. I have 2 N2s and have used both the dual and single Bondtech and I can tell you that my printing became reliable after that. If you get the dua...

Bug with IM 3.4

I created a new printer and a filament type. When I try to use the new printer, it does not show up in the drop down where I create a filament template, nor does the filament I just created show up. Secondly, why is IM asking for a printer type and the filament when it is on the top of the form? It ...

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

I am now thinking that I will not try the Mosquito. My E3D is 42mm tall and the Mosquito is 41mm. The weight of the E3D with heater, fan, TC and wires is 94g. It is more weight than the original R3D at 73g, but the trade-up is worth the weight. To try the Mosquito means creating another printhead, b...

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

Yes. That is correct and why I spent so much time working out a system to produce a holder that would work each time. One of the main tricks with the Igus bearings is to measure the thickness around the circumference. It will vary, but one side will always be thicker than the side 180 degrees opposi...
