Does anyone know if you can completely disable either of the nozzles and print from the other? I’m waiting for a part (Left Hotend Heating Assembly). I have completely removed and disconnected the left nozzle and heating assembly and I want to use the right nozzle to print.
Right now, the timeline I have is that the part will arrive by Nov. 23rd. I don’t really expect it to take that long, but if it does, I’m going to be severely disappointed that this machine is down until this part arrives.
I probably should mention that I have tried with and without an AMS hooked up to my printer. I was hopeful the printer would behave differently when only loading filament from an external spool. For some reason, it keeps trying to heat the left nozzle during the pre-print routine and throws an error that the left nozzle temp. is abnormal. (Obviously, it’s not installed)
Putting this here for anyone interested. It appears that turning off automatic flow calibration stopped the pre-print routine from trying to heat the left nozzle. I just got a print going manually from the touch screen, though I might have changed something else and overlooked it. I will add an update here if I find something different tomorrow.
Well, this is a bust. I cannot figure out how I got the machine to print last night. I have been unable to keep the machine from trying to switch to the left nozzle during the pre-print routine. If anyone has any ideas please share them.
A tip, edit your original post when others have yet to take a look.
Adding extra posts makes it look like someone is helping.
Can you explain why you had to remove the left nozzle?
I do not have the printer, but I have two thoughts:
A lot of things that have two main parts require both to be installed before they will function. That may or may not be true here. It may just need to sense it exists, even if there is physical damage.
Surely the sliver controls which nozzle is targeted, this is something you control before you send the job to the printer. Do you have something still connected to the left nozzle input, like and AMS, even if you are not using it. Disconnect that.
The left heating assembly cable was damaged. I’m waiting on a replacement part to fix it.
I’ve completely removed the left heating assembly, nozzle, etc… The printer recognizes that the nozzle is not there.
I do not want to reinstall a heating assembly with bad wires. I did successfully get a print to run overnight last night without the left assembly installed. I don’t know what I did other than I had my AMS disconnected and printed from an external spool. I also disable the automatic flow calibration before printing. I’ve been unsuccessful all day in repeating this process.
Everything is disconnected from the left nozzle, including the PTFE tube in the printer that runs to the nozzle.
I’ve made sure to have the right nozzle selected in the slicer and directly on the printer touchscreen. I have tried printing from both. For some reason, during warm-up, the printer switches to the left nozzle and gives a heating error. I can ignore/resume, but the printer just sits still and will not move back to the right nozzle to start printing.
I’m really confused because I did make this work once. I’m okay waiting for the part, just hoping to get some use from the machine if I can in the interim. The estimate for the part delivery is Nov. 23rd.
