Hi Jim,

I think I have some PCBs left but not sure I have all the components, I'll have a look and let you know.

Phil

John,

Great, glad you got it working

Or this one

**LINK**

I'm sure they are available on Amazon and ebay, is this one the right dimensions?

Looks good

Nice solution, a bit more "meaty" than my approach, I may have overthought it maybe a angle bracket would suffice hmmm...

Brian,

Pictures as requested

Yes the gears are enclosed apart from the end which I plan to cover with a piece of perspex. The inner sleeve is fixed to the lathe bracket but the outer clamp slides around allowing for a variable mounting angle to clear the bits on the lathe.

Ofcourse, good luck with your twisting.

Hi,

I've had my stepper mounted end on to the leadscrew but always wanted to have it at right angles but didn't want to spend the cash on a proper gearbox so I've been playing around with the idea of my own mount.

I ordered some "Mitre / Bevel" Gears from China for about £3 and did a design in F360 with the idea of 3D printing them, yes I know that the 3D printed parts may not be up to it but it's not going to cost me a lot to try it out.

Anyway i've got the first off prototypes printed and now just checking for fit. Here are some pictures just incase it sparks any ideas .... Still very much a work in progrgess though.

Andy,

I think the layout on the W180 and 240 are quite different than my Mini lathe but you're welcome to use what I have, pictures are in my albums, I'm now looking at converting to a right angle drive arrangement to reduce the width of it all.

Small Chinese job from Warco Super mini lathe

Nice job, I need to look at mounting mine at a right angle to the leadscrew.

Following a request on the Clough42 GIT hub I put my bracket designs I made for my small WARCO (Chinese) lathe and ELS on thingiverse Here

Dias,

That's great news, I suspected it would be the wiring of the coils.

Phil

Dias,

See if this helps

how to identify coils

Dias,

I'm at work at the moment so I can't check but what I can say is that with eight wires you have the opportunity to wire the four coils in series or parallel, maybe you've got them wired in parallel which will halve the resistance and double the current?

Use a multimeter to identify the coils and their connections and wire them in series by checking the resistance maybe this is your issue..... or not.

I just realised you've got them wired in series but just check the resistances to make sure the connections are correct.

Hi Dias,

I'm at a loss really, on my driver the SW4 halves the current in idle mode, it only needs to be switched once and left, this is from the instruction manual

"Standstill Current Setting SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current, and ON meaning that standstill current is set to be the same as the selected dynamic current. The current automatically reduced to 50% of the selected dynamic current 0.4 second after the last pulse."

Maybe you need to get the DM542T

Phil

Good news Dias,

As they are isolated with opto isolators they are electrically independant of each other having said that I would always power up the micro-controller side first so if there was any spurious signals prior to being in a steady state the should drive the stepper motor, not that there should be any spurious signals!

I'm my driver there is a jumper to set the stationary current to less than the drive current, does yours have one?

Phil

Phew! that's good news, glad you sorted it out.
