Hi Gray
Thanks for the link.
I haven't done that but it looks a good idea so I think I will order some more belt
Bob

 

I will if I can get the axis,s setup the x and the y are not playing ball .
set the Z up no problem
Bob

 

I have just had a thought I may be wiring the motors up incorrectly.

I have mine wired as bipolar parallel. should they be bipolar series?
any body help out there please.
bob

 

Hi Robert
I am Using
DQ452MA on the Z
and
CW230 on X and Y
I have nema 24 425oz 3 amp on all axis 1.8 deg 1/8 (1600) microstep

Bob

 

Hi Robert
I will give that a try tonight.
Thanks
Bob

 

Hi Sarge
No the board didnot come with the kit. I made it out of 3/4 MDF.
holes drilled at 50mm centres and the blind nuts hammered into the underside.
Yes I am using Vslot it came in the kit.
Bob

@Robert Hummel
"I would first change up to 1/16 due to the fact you have the power in your motors in turn you should see smoother operation.
Second running the motors in series increases winding resistance lowering the motors current rating.
Run them parallel for taking advantage of their full specs"

robert
Did that and it made no difference.
So I had a cup of coffee and a think.
Why did the Z axis work OK and not the others?
So I stripped down the contol box and put the z driver onto the x axis hey presto it worked.
I then had a closer look at the driver for the x and y.
the clever chinese used "0" for on and "1" for on for the dip switches. So I was running the motors at .9 of an AMP.
My fault I should read the instructions first.

Thanks
Bob

 

thanks Tweakie
i wont know till the weekend if it all works ill let you know
bob

 

It's alive
it works thanks to you all for your help.
I have just got to figure out how to load videos now
bob

 

Cheers Gray
now to finish of
limit switches,
estop
ETC
now to strip it down as the extra belts have just arrived.
bob

 

Hi All
The first phase of the build is complete. Rails screwed together, double belts fitted, (Thanks Gray) Estop and limit switches done. bracket for water cooled spindle made and fitted.
The first job the machinne did was to make the brackets to hold the switches.
All seems to work fine.
Now to make my guitar.

 

Here is the next part to see the light of day

Thanks Roberthttp://openbuilds.com/threads/890kv-ox-rc-spindle.315/ and Tweakiehttp://www.openbuilds.com/builds/software-speed-control-of-a-brushless-dc-bldc-motor-from-mach3.762/

I suppose this makes up for Wales not getting the 6 nations cup.

Thanks all
Bob

 

Hi All
It's been a while but I have been busy at work.
I have made a few things on the OX . But now I needed to make a couple of curcuit boards.
so i needed to make a proper bracket for the Brushless motor.
so made one on my 3D printer.
here are some pics.








I will upload the sketch and the STL if anybody is interseted

All the best
Bob

 

Hi Mark thanks for the kind words.
I haven't had chance to use the VFD for long as I have a problem with Mach 3 tripping I have tried all the usual
cures but have not had much luck yet. I will keep trying.
as for the outrunner it seems to be excellent I have made a couple of signs with it without a problem.
now i have made the proper bracket for it I plan to use it more. I also use a router which has given me no problems.
Except noise

Bob

 

Hi All
I am after some advice please.
I am about to start cutting some aluminnium plate on the OX and i am looking for some advice on feeds and speeds.
the cutter is a 4 flute 6mm dia end mill the plate is 3 mm thick.
Can someone advise on the feed rate of the cutter for this aplication.

Thanks
Bob
