Re: Intro with printed plane!

PLA. It really is easier to print than ABS by a long shot.

Re: Intro with printed plane!

For the elevators/ailerons it's printing them vertically that does you in. The part gets pretty wobbly as gets near the top and the hot end mostly just pushes it around.

The fuselage printed up very nicely. I followed the recommended settings and printed it (on my V2) at .2mm.

Re: Keep needing higher and higher temp settings. Max V2

I did some research, and the resistance range for the 160C - 260C range that our hotends work in is about 500 - 50 ohms. As the temperature goes up, the resistance of the thermistor goes down. So, it should be around 500-ish ohms at 160C, and 50-ish ohms at 260C. Looking at the Rambo 1.2 schematic (...

Re: Keep needing higher and higher temp settings. Max V2

"The temp indicated by the thermistor always matches what I set it to, so it's not like a heater that can't keep up, that would indicate a lower temp than expected. No matter what I set the temp to, It'll warm/cool to that temp." That's really just an indication on how well your PID is tun...

Re: Intro with printed plane!

A late welcome!

I'm printing out the glider from 3DLabPrint, and the ailerons are going to drive me batty(er). They're printed, rather poorly, but should suffice. I'm currently waiting on some clear PLA to show up to do the rest of the print.

Re: Ros tock V3 heated bed not getting hot enough

The greatest improvement that I made concerning ABS was to stop using it. Try HIPS instead. It's a lot like ABS, but much easier to print. But to seriously answer your question, probably better adhesion and less curling. As for getting more heat out of it, try this: https://www.amazon.com/Pyramid-Co...

Re: Hans makes a build thread for a Rostock Max V2

I had the same extruder issues (as apparently do many others), so I replaced my extruder with a prusa style extruder fitted to a NEMA 23 motor. Stalling is a thing of the past... The power supply died after less than 100 hours of printing, so I strapped my Astron RS35M onto my V2. Life is great at 1...

And you can try opening a sketch in Arduino that does nothing more than a simple "Hello World" to the display. If it works correctly, then I would have to say that maybe something got corrupted in your firmware.

Re: Ros tock V3 heated bed not getting hot enough

Re-tuning is easy. But I don't recall it making any difference when I did mine. Which was a good thing... I was hoping that you could see if there was a voltage drop across the connector, but if you start out with 12 volts, and end up with 12 at the bed, then I think that you are good. A picture of ...

Usually that's a sign that a cap is going bad, or your power rail is glitchy. Try re-routing the cable to the LCD away from any other wires as well.

Re: Ros tock V3 heated bed not getting hot enough

Okay, so the controller also agrees that the bed isn't up to temp. That's why it's calling for power continuously. So I think that we can rule out the PID. While the bed is heating, what is the voltage at the bed terminals? Try to measure before and after the connector. This will give us an idea if ...

Re: Ros tock V3 heated bed not getting hot enough

Is the LED on the bed "On" continuously? In Repetier does the temperature graphs show that the output to the bed is on continuously?

And you can try temporarily driving the bed directly from the power supply (obviously you can't leave it like this). What temps do you get that way?

Re: Print quality woes

One of the printer control programs includes a graph showing the output of your heaters. Use that while you are trying to heat up the bed. If the output to the bed is 100% then you have a capacity problem, if not, it's a control problem. Try that and let us know what you find out.

I would try a raft with the "Expand Distance" (in MatterControl) set to 0 mm. For some reason this seems to help my printer out (a lot!!) when it wants to start curling. As for your bed maxing out at 95, I would take that with a grain of salt until I made an actual measurement of the bed. ...
