Anyone got any spare? PM me a price. Popped a driver this morning....everytime I fix a problem a new one comes around :)

Thanks, Phil

Need 2-3, just killed another, think my X-axis stepper is faulty. It moved a bit then pop and wisp of smoke :(

Cheers, ordered some last night but wanted a couple to get going, need to know why that axis has killed 2 drivers :)

Thanks for the help!

What voltage were you running them on?

What voltage were you running them on?

They are running at 24.0v(exactly). I'll give you the whole story to see if you can pinpoint anything.

The control box is the one that comes with the 3040, never had a problem until it was in storage while I moved. I unpacked it one day, set it up, hit the switch and poof, blue smoke was escaping from the breakout board. One of the buffers had popped so I assumed the breakout was gone and bought a new one. After a lot of tracing I figured out which wire went where and hooked up the Y axis. Success! It moved both ways and much smoother than before so I hooked up the Z axis and again it worked better than ever. Then came the X axis, after hooking it up the motor moved briefly then stopped. I assumed it was the wiring so I ran new wiring between breakout and driver and it was the same. I then moved the Y axis driver and plugged it into the X axis wiring and poof, more smoke. The motor moved about 100mm before killing the driver.

Is this a motor fault, it sounded ok for the brief moment it moved, or is it more likely to be damaged wiring between motor and driver?

Thanks for any help, Phil

I will end up getting some soon, but been made redundant and money is low. But I have a couple of paying jobs lined up....bloody catch 22 :D

Another 3040 owner here.

original breakout board on mine had E-Stop wired to something completely different, the box seems a bit thrown together.

The wiring on the frame seems to be have been made with some sort of super brittle wiring, really not up to getting flexed all the time, rewired Z &X on mine and replaced the TB`s , its easier to cut the chip out and mop the pins off , reassembly pretty straighforward then.

This may be a sign of things to come, i doubt this is a one off.

Is there a simple way to test the stepper motor?
