Re: Extruder Acceleration - Holy Crap!

M201 X2000 Y2000 E1000 Z900 ; acceleration

Is the above 'jerk' actually the derivative of acceleration per time? (da/dt)
I just thought that would be a function of the components, nothing you could control.

Re: When to use polyimide tape

I have printed on the Kapton tape on glass with both PLA and PETG without any other adhesives, just bare tape, with 100% success. I would definitely suggest trying the tape side of the glass with no hairspray. I have just started using a MIC6 plate with a PEI sheet on it, printing PLA and PETG with ...

Re: What filament for airplane fairings

John,

I have been researching this exact issue for some time now. PM me, and we can talk on the phone.

Re: Dual Extruder Not Acting Right in SImplify

Well, we finally figured out the problem with my dual extruder...My knob was too big! Seriously, it turns out the Z-axis knob was pinned against wire harnesses when the carriage was at minimum X-axis travel. Several ways to fix this, including just removing the knob, so all is now well. Many thanks ...

Re: What filament for airplane fairings

I would suggest nylon, polypropylene, or polycarbonate. The polycarbonate is tougher and harder to print well. The nylon can be dyed to almost any color, will survive lots of flexing and vibration. Polypropylene is most flexible, resists moisture best, and least dense. (Nylon = 1.14 vs. Polycarbonat...

Re: What filament for airplane fairings

Unless this is for an Experimental or an RC, the answer is, "None". You might run afoul FAA regulations, since the parts would have to be tested. I also doubt the process has been approved by the FAA. Boeing and some of the other big companies have just begun 3-D printing metal parts for airplanes.

Do not put it off too long. As I understand patent law, since the day you published this, you only have a year to file for the real thing.

Re: Dual Extruder Not Acting Right in SImplify

zemlin, Here are the results. While talking to the Tech Support guys, we did change a few things, including the z-rate of travel. I do not remember specifically changing any acceleration rates.

Re: Dual Extruder Not Acting Right in SImplify

Jules,
The Z-rod is fine. It only acts funny and makes odd noises at that particular time; perfect operation otherwise.

zemlin,
The Support guys looked at that output, but I do not know if they thought about the acceleration, though. I will check on that.

Re: Dual Extruder Not Acting Right in SImplify

No surprise, I reloaded the firmware 3-4 times, with no change.
