I went to clean the nozzle tip and the 2 heat blocks touched. now the right extruder stepper wont turn when I try to load filament have swapped stepper motors with the left and still no luck any help would be greatly appreciated
When you say swapped steppers, did you plug the left where the right goes and then load the right extruder?
no I did not because then in the slicer software I need to tell it to print with the left nozzle and my slicer crashed and I cant get how to change nozzles on Cura not unless I’m missing something simple all though I have been over thinking it lol
Hi @John_LaBaff,
I will help you try to isolate and troubleshoot the problem you are having. Full disclosure, I don’t own a CTC Dual.
Firstly, most 3D printers will not let you use the extruder stepper motors unless you are heating the nozzle to 180C (min temp).
Whenever you are switching wires/and electronics components make sure the power is disconnected.
Maybe the problem is in the wiring, try switching the wiring. Take the wiring from the left extruder and use it for the right extruder if possible.
If this works, it means there is something wrong with the wiring on the right side.
Maybe it’s a motor issue, try plugging in the right motor to the left extruder and see if it runs. If it works, you can be sure that it’s not a motor issue.
If it doesn’t it could be a motor issue.
Finally, check the wiring in the electronics box, maybe something is loose. Maybe the stepper driver is damaged.
You can check if it’s a stepper driver problem by switching the left and right stepper drivers. If it works, it means your right extruder stepper motor blew out.
If it doesn’t it means it’s not a stepper driver issue.
Let us know what happens, and if any of these worked for you.
All the best, hope this helped.
No I mean literally plug the right motor in the left plug on the board and then hit load filament on the left
ty that’s what it was killed the stepper chip does anybody know what the factory stepper chip is so I can get a new one for I can print in dual colours again ty in advance
You need to figure out what type of stepper driver you need. If your stepper driver is green it most likely is the A4988 and if it’s people it’s probably the DRV8825.
Once you figured out which one you need you can order it from EBay, Amazon, or maybe find it to your local hobby electronics shop or 3D printer shop.
Can you upload a picture?
I can’t tell. The heatsink covers up most of the driver. But from what I have read it’s most likely a A4988. You could also ask your supplier.
ok ty so much for your help yall its been a great help
No worries, hope you get it running again soon.
all ready back up n running just makerbot software has changed so need to re learn all that. what do u guys use for slicing software
I use the Simplify 3D but it can be expensive to get a licence. I also heard good things about Cura
