Nozzles randomly switching during print

I noticed that when the printer is idle, the nozzles will switch on their own. I didn’t see any damage to the cable running between the filament sensor and the servo.

Re: 2 year with PRO 2

Been printing two years with a Pro and one year with a Pro Plus. Ditto all the comments. The hot end is a nightmare! I would hope, at some point, Raise3d offers a replacement hotend that is a bolt-on replacement for this nightmare. Slice Engineering’s Copperhead is a drop in replacement heat break ...

Re: Liquid cooling for everyone

cant seems to find half the stuff on Amazon US. usually copying the technical name from German Amazon to US yields better results. You can find tubing and fittings on McMaster-Carr. I can try and put together a list of the parts I used, but I don’t have the printer in front of me (office is shutdow...

Re: PLA blockage

Thank you for all your replies and your warm welcome Markus64. I have taken Markus's advice and started to machine a couple of water jackets closely following his designs from the pictures on this site. I am having problems trying to locate the barbed fittings on the jacket. The only versions i can...

Re: Liquid cooling for everyone

Bummer, is there a bad solder joint or something on the actual radiator? I’m using the same/similar kit from E3D and haven’t had any issues, but I’m not sure if it’s any better than the kits on AliExpress.

Re: Liquid cooling for everyone

Looks good. Might be a good idea to flush them out before installing them in your loop so that any leftover powder doesn’t get in the pump.

Re: Liquid cooling for everyone

How are you powering the pump and fan? My original plan was to tap into the power supply on the printer, but ended up using a DC adapter that’s plugged into a power strip (along with the printer).

Re: Liquid cooling for everyone

I had to scrap the first set of parts that I made. OUCH! :o :x Still very well done, mdana! What can you report positive about your mod? Did you ever have problems like heat creeping or overheating the hotend after the conversion? This solved the heat creep issues and haven’t had any issues with le...

Re: Liquid cooling for everyone

Update: The design of the heat exchanger is basically finished. I will have two prototypes made from aluminum using a 3D printing SLM process. I expect the finished components to be available until around mid-May. The water cooling system "Titan Aqua Watercooling" from e3D is used as the ...

Re: Liquid cooling for everyone

I have a similar design that was printed in aluminum as well as a machined version. I can share both step files as well as the SolidWorks model. One bit of warning, make sure you have enough clearance on the back of the block so it doesn’t interfere with the housing for the nozzle lifting servo. I h...

Re: Clog or heat creep

I’m using E3D’s water cooling kit (https://e3d-online.com/water-cooling-kit) and printed (DMLS) the water blocks out of aluminum. There’s more info on water cooling in this thread: https://forum.raise3d.com/viewtopic.php?t=10787

Re: ERROR: Network not connected

On my Pro2 Plus, the extension cable that runs from the board to the back of the printer was bad. I was able to get a new cable under warranty, but never got around to installing it and just connected the Ethernet cable directly to the board.

Re: Nozzle cleaning

I’ve never had any issues with the nozzle itself clogging. Typically, clogs or jams are due to heat creep above the heat break or if the nozzle wasn’t installed correctly (not hot tightened against the heat break).

The clearance is the same for any nozzle. You change your first layer height in IdeaMaker.

Re: 2 year with PRO 2

Agree, the print head is a nightmare to work on. I have all of the fan cables zip tied to the outside of the extruder (broke a wire at the connector the first time I tried replacing a fan). For the price, they should have just used V6’s or Mosquito hot ends with a mount that doesn’t lose your x, y o...

Re: In dual extruder mode - why a retracted nozzle continuously emits melted filament parallel to the other working one

in IdeaMaker, you can set the inactive extruder to cool down (temperature setting). Enabling wipe wall and wipe tower (ooze settings) will help purge the filament in the nozzle and prime the extruder when it switches nozzles.
