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

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 E3

Now 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

Config file just in case
0_1539324837217_config.g

just got a reply. They are supplying v1.03 now.

I ordered mine directly from duet3d. I'm sending mail directly to them now.

I love the board, got one since February but was so busy that I didn't start the assembly until this month. Perfect board for my new corexy build. but I do notice that it is v1.02 board instead of v1.03.

If I order one more DuetEthernet today (for my delta printer), is it certain that I will get an updated v1.03 board. That extra fan protection seems interesting.

Thanks!

Ps. My old board has one fan mosfet blown-up. could I send it back for repair or is there any option available? I live in Thailand btw.
