X Stepper Keeps Dying
all thoughts welcome
about two months ago the x stepper on my triac died, got a new one. well last night my brand new 2 month old stepper died.
im aware steppers are pretty hard to kill, anyone got any suggestions? could it be the x parker sd2 drive card causing this?

Re: X Stepper Keeps Dying
I would check the wires from the motor. Look for fraying which would cause a phase to short to ground.

Re: X Stepper Keeps Dying
is the stepper getting hot (too much current).
Check the connection box is not full of coolant (more likely to cause the drive to fail).
Do you have the tension on the belt too tight.

ok wiring is fine, it is a brand new stepper soMartin wrote:I would check the wires from the motor. Look for fraying which would cause a phase to short to ground.

stepper was an exact match for the original one that came with it tom and didn't notice any heat issues.angel-tech wrote:is the stepper getting hot (too much current).

connection box is perfectly dry and stepper is completely dry.
now like the original stepper its an 8 coil stepper. so only 4 were wired in, just wired in the other 4 coils from the stepper that weren't being used and it works perfect. so it would seem 4 dead coils and 4 working coils.
this is an odd one
changed x and y drive cards over for a 5min test and both seemed fine

Re: X Stepper Keeps Dying
I don't think you should have wired it so that 4 coils were not used, the coils are usually wired in series or parallel, but i'm pretty sure they're all used.

I still have it to be fair

Re: X Stepper Keeps Dying
But the eexisting stepper that came from denford only had 4 coils wired not all 8

Re: X Stepper Keeps Dying
maybe Martin can shed some light, I would have thought all 8 coils would be wired in to the 4 wires. Maybe you thought the linked coils were just wires not connected. Did you measure the resistance across the coils.

Re: X Stepper Keeps Dying
yep we measured all 4 of the not connected one and they were not connected to the machine.

Re: X Stepper Keeps Dying
were the unused wires connected to each other in pairs
Re: X Stepper Keeps Dying
It does sound strange. I Don't see why we would have left 4 wires seperate.

Re: X Stepper Keeps Dying
nope 4 unused wires not connected and each had heat shrink wrap on them
will dig the original stepper out when i get home from work and post some photos

Re: X Stepper Keeps Dying
here are, original stepper
as you can see only 4 connected, ignore the white connector we were using that for testing purposes. but as you can see other four have been cut real short and they were covered in heat shrink wrap to stop them shorting etc...

Re: X Stepper Keeps Dying
it's normal to have the other four wires short and heatshrunk, but they're normally connected together in pairs, as they're the centre taps of both coils, or end and start of A- A+ and B- B+ coils.
Re: X Stepper Keeps Dying
It does seem strange. Was it the X axis on a triac?
