Y driver issue?
-
Today, I notice that my CoreXY machine (Hypercube Evolution) makes rattle noise on Y motor and it refuses to move properly. It worked fine for past several months.
Here are things that I tried
- Swap X/Y motor wirings (I shut the printer down before doing it)
- Use new cables
- Test with spare motors on both X and Y drivers
- Already make sure that connections are stiff
- Connection on all motors are 100% correct
- Tested with new motor outside the printer to make sure that belt tension isn't the case.
- Tried to increase current to 1000mA (from 900mA). (X driver already works fine on 900mA).
X driver could drives everything normally with all those changes with zero issue. Problem seems to persist on Y driver.
There is no sign of burnt mark on Y driver and nearby SMD chips . They look just normal as others.
To not ruins my printing schedule. I use this command to remap Y motor to E1 driver.
M584 Y4 E3Now printer could move all axis normally. Printer is up and running again. But I have to ditch my second extruder plan in the future.
Here are the questions.
- Is my Y driver already blown up.
- I bought this board since February this year. So I assume there is no more warrantee? I already blown one fan mosfet though...
- Replacing/reflow driver locally seems impossible. I saw Duex2 0.8a is currently on sale. Is this a viable option if I buy this just for extra extruder? Should it be much more economical and way less downtime than asking someone to repair my board?
- If above option is feasible. Since I'm using BLtouch to probe printer bed and some pin on 50-way connector are occupied. Where will all those pin goes if I choose Duex2 route. I checked the instruction here https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe but I'm too dumb to figure where and how. There is no wiring picture just like normal use case.
Thank you

It does sound as though the driver has failed. You could use a DueX2 as you suggest, or have the driver and the fan mosfet replaced. Forum user W3DRK does Duet repairs in the US and I do them in the UK.

Sweet! I will buy that soon. Thanks for your help.
