I just had a another go at setting up with the charge pump engaged. no result.

I have the charge pump set to: port1, pin16, active high,
in the general configuration i have set: charge pump on in...

I am in the middle of a rewiring of my control cabinet with the usb smooth stepper i purchased a while back and have hit the wall trying to tune the motors.
I have read that the smooth stepper may...

Hey here, Hi.
i also have a sangmutan. Mine has a 500 watt motor attached and is coupled toa taig milling head.

I would suggest the long 4-pin wire wired between TTL terminals.
TTL has the rx...

i just googled, and sangmutan is still around. what i did when i ordered was email for a special order of a controller with a smaller frame motor. the motor i asked for was 500watt in a 80mm square...

i recommend the sherline spindle. i use a taig ER spindle coupled to a 500watt 5000rpm sangmutan brushless DC motor. it has the speed range to do things with the smaller bits and has the grunt to...

the build looks great, good to see you have started making parts.
one thing i would encourage you to do is re-mount those electronics in an old stripped out pc case. the thing being that...

i also got my bearings from linearmotionbearings2008.
don't define your machine around the parts you find of their site, ask for an email address and go through a quoting proccess to get exactly...

for ballscrew end bearings you should be looking for cheap chinese
ballscrew endbearings in the FF and FK type, and have your ballscrew or leadscrew machined to suit.
I like your side panel...

it would seem i am in ignorance.
i asked you to elaborate on active and neutral swapping purely because i over looked the significance of it when i did the thing.

i have now taken the internal...

well thanks guys, i think i will be getting the electrician neighbour around to check the earthing points.

i'll keep you posted.

yeah thanks for your concern. i go to great lenghts to star earth every thing i wire up.

with the case in question i have an earth coming from the plug socket, pop riveted to the chassis along...

hi guys, i have recently re-wired the control box for my machine and found once again that the hair on my arm stands on end with a very definite tickle sensation. it was one of the reasons that i...

what is the frame type that the sangmutan motors use?
can you get a threephase in these type frames?
that would be the biggest thing holding us back from going three phase.

oh!

Hi i just have a small problem with the new smoothstepper i am installing.
It is in a new case along with three 251's and a Bob from homanndesigns.com.au
The installation was fine, and the...

so, like i said before.
when the two ends of a coil touch it creates a magnetic resistance, and binds up the shaft
use this to find the correct wiring.
unscrew the motor wires from the driver...

if you don't won't to buy a multi-meter you could always try a different wiring.
with one of your four wire steppers try swapping two of the wires.

but you can't be sure without it.

thats a good choice, you will be in good company.

no, stop. tell us more about your setup.
a six wire motor doesn't mean its a unipolar driver. and when was the last unipolar driver you saw.

i think if you have done the soldering your self you...

i would just hate to see the producer of these motors seem stupid because the timing wasn't set properly.

sorry to ask. but how many of you have ruled out a timing misalignment?
the sangmutan is a sensored motor, does retarding the timing have any improvement?

your best bet is the sieg that they sell over at little machine shop.
it's $3995, but it is a machine that will keep you going.
other than that, i would prefer a syil. they are a really similar...

i think thats a lot better.

something the other guys may not have hammered home is that you need four linear bearings an axis, or that is, two linear bearings a rail.

if not you will seriously...

on a milling machine, typically the x and y axises are inverted in the pinout page.
on my fixed gantry router the z is the only one inverted.
it is matter of mechanics that you invert the axis and...

hi, how are you.

to answer your question you first need to make sure that your axis is in the correct direction. you can change direction by ticking the box next to the
direction pin in the...

sounds like you need something like a tormach.

you are going to have to do some research but you should find a local source for composites and make your challenge a little easier with a flexible silicone or urythane

you mentioned milling machines. try syil mills at Syil America
they shoul be up to most of the tasks you put to it. the X4 is $4500 , a good choice in my opinion. and they are in milling machine...

this is a bit of a downer i have to say. i have been raving about this motor and controller.
i was able to get sangmutan to design a motor to my specs and i was thinking it was too good to be true....

yeah of course. there is gecko themselves that you can get the drivers from and cnc4pc should stock the rest of the electronics
