Re: V2 with Duet and smart effector

The steps/mm for the Extruder is completely bonkers if you've got the EZStruder on your machine. :)

Can you post the bed.g file as well? Sorry I forgot to ask for that earlier. :(

Re: Noz: def, heater decoupled (RMV2)

A thought just occurred to me - you changed the hot end, thus how the hot end is heated (resistors vs a heater cartridge). Did you re-run the PID tuning process? If you didn't, that might explain why the hot end isn't heating fast enough. Give that a shot and let us know how it goes.

Re: V2 with Duet and smart effector

Can you post your config.g file? There is no "v4 firmware" - RepRapFirmware isn't like Repetier Firmware. With RRF, 100% of the configuration is done with G and M code commands and there's no need for any firmware changes. That being said, what version of the firmware is reported by the web interfac...

Re: Rostockmax v4 vs Artemis?

The forum here used to be very active, but then someone had the bright *coughs* idea to create a Facebook group, and that pretty much sucked all the air out of the room. ;)

BTW, if you want to see how NOT to finish a v4, watch the 2nd video. "Derptastic" is a pretty apt description. :D

Re: Rostockmax v4 vs Artemis?

Both printers share the same motors, hot end, and electronics. The Artemis 300 is built a bit "beefier" than the Rostock MAX v4. The v4 is a point in the evolution in the Rostock MAX product line and includes components from the prior generation (3.2). The v4 is an easy to build kit aimed at folks t...

Re: Rostock V4 - SE300 - Barrel fan not working.

Also, the cold-section fan will only be running when the hot end temperature is > 60C or so. You should also check the fan output with a multi-meter after the hot end is at temperature.

Re: Using Fan2 output

It doesn't look to me like you're over-driving the extruder stepper. What you might want to do is just piggy back the extruder fan off of the output that drives the cold-section fan on the hot end.

Re: Artemis 300 whiskers

Try backing off the temp 5 degrees.

To tune this for a filament, you should print two small cylinders about 15mm in diameter about an inch apart. It's a great tool to get rid of stringing. Start at 195 and see how that goes - if it still bad, bump it down another 5 and see how that goes.

Re: Using Fan2 output

Well there IS a pins.h file - it's used by the firmware. However, that's not where fan pins are assigned. The problem you've got is probably due to a motor that's being driven at too high a current. Can you attach a copy of your Configuration.h file to a reply for me? I'd like to see where you've go...

Re: Artemis 300 whiskers

That's a phenomenon called "stringing". It can happen if the temperature for the material you're printing is too high. I take it you're using one of the SeeMeCNC Cura profiles? What material are you printing with?

Since those wires don't typically get stressed, the other wires are most likely just fine. Replacing them all is insane overkill.

Re: Using Fan2 output

By "extruder" are you referring to the extruder stepper motor itself?

Note that any fan pin changes are going to be done in Configuration.h, not pins.h

Re: Artemis 300 RTP

Cura may be adding an M84 command at the end of the job. This will turn the motors off. The weight of the effector could then pull it down into your print. Check the post-print code in Cura. (not sure where that's at though)

Re: Rostock Max v2 Noob question. Help please

You can replace the two 6.8 Ohm resistors with a single 12v heater cartridge. I did a video a number of years ago on upgrading the stock hot end with a threaded thermistor and a 40W heater cartridge. You'll need this: https://www.ebay.com/itm/222900991161 (threaded thermistor) and this: https://www....

First of all, don't knock yourself - everyone started out somewhere. When I started working with 3D printers, I was a rage-quitting, curse-filled, madman.

Did you update the thermistor type in the firmware after you changed the hot end? The E3D thermistor is different than the one in the stock v2 hot end.

Re: Noz: def, heater decoupled (RMV2)

Check the voltage at the RAMBo while you're trying to heat the hot end. It should be 12v. Some of the older ATX power supplies give up the ghost.

Also check to make sure that the wires are not lose in the compression terminal on the RAMBo end.
