Matt,
That looks about right! :) just dirty enough
Nicely done.

Matt,
That is a good looking toy box. Congratulations. :)

Matt,
Great looking machine.
Inspiration to the rest here in Oz - need to get mine going:)
regards,

Hi Matt,
May I ask you an update on your situation with your smoothstepper as you reported in your below post #63 ?
By the look of some work, you’re doing fine !?
Thanks, Robert ;)

Hi Robert,

The EMI filter on the VFD input and the toroidal ferrite on the VFD output to the motor (as pictured in post #67) was all i needed to do to stop the SmoothStepper from losing comms with the PC. I haven't had any issues since. I still want to implement RS-485/MODBUS control of the spindle so that might open another can of worms. I'll let you know how it goes.

Matt, may I ask what wire (1mm sq or 1.5mm sq) are you using? what is the ferrite dimensions and the number of rotations.

Hi, Matt, Thanks for your follow up.
Yes, please let us know how you’ll be doing with your RS-485 experiment / set-up ?
Amicalement, Robert ;)

Matt

Just an enquirie about the motors. Im thinking about getting these ms motors also, but motor with gearbox 3.6:1. By the looks on the pictures they look great, are they performing good?

thanks
francis

Hi Francis,

They have been great. No complaints here. But i can't talk for the gearbox version. I have heard (not confirmed though) that these motors are the same as the ones sold by Keling in the US. They have the same part numbers and specs minus the 'KL'. As i think i said elsewhere, if you can find someone to share in the shipping cost you will get an even better bargain. But my motors+shipping cost less than the equivalent Keiling motor not even including shipping.
In short, very happy with them.

Hi Matt

I am in Sydney, I'm after a 40volts 600VA toroidal transformer or like you, 2x 300VA... Can tell me where you found yours? and also what kind of outputs it has.

I found this on ebay but I am not sure if they are suitable:

Toroidal 300VA, 40-0-40Vac

It is centre tap 40-0-40 output. There are two modes of connection.

Mode A (Series for Double Volts)
3.3 amps

Mode B (Parallel for Double Current)
6.6 amps


thanks,
Francis


by the way, I bought the motors from MS they look great. http://www.mechmate.com/forums/showthread.php?t=2214

Hey Francis,
Sorry, not sure how i missed your post. I bought my transformers from Altronics. http://www.altronics.com.au/index.as...=item&id=M5535
I'm no expert in transformer wiring, but I didn't think a centre tap winding will be sufficient. When you parallel the windings you need to connect the two starts and two ends of the windings, but thats not possible on a centre tap as the start/end the two windings are connected.
Good to hear your happy with your motors. Can't believe you're using such are large module rack!

Question on Drive reduction
 

Hi Matt,

Love the look of you stepper belt drive, How is it preforming? How smooth a radius cut are you getting with 2.4 : 1. Any change you would make with hind sight? Do you have drawings for the plate parts that you are preparded to share.

Tanking you in advance

Graeme

HI Again
 

Hi Matt,

sorry about all the questions, Could you indicate details of the stepper motors you are using? How are they going for you? About at the stage to order stepper motors. Looking at MotionKing 34HS9801 however should consider suitable steppers from another source.

Any comments on source, part number approx. cost, delivery issues?

Feeling godd bearings arrived this morning. steel parts are cutout but not bent yet.

thanks

Graeme

Mach3 plugin for Huanyang VFD
 

For those that are interested, i have finished writing a plugin for Mach3 to control the VFD via RS-485. I have posted it on the Mach3 forum here. I have been using it for the last few weeks without any issues so i hope it works for everyone else.

congrats Matt !

Great, I will try it tomorrow and let you know how it works.:D

Thank for that Matt, our USB to RS-485 converter's should be here any day now. And when feeling better I can finish wiring up the BOB's and everything else I can build the coolant flow sensor circuit.

And I forgot to say feed the fly pigs. (I got a lot to do)

Matt could you advise your supplier of the rack and pinions im having problems finding some at a good price.

Regards Andrew.

Believe linear bearings do rack and pinion not sure if you've been in cotact with them or the price but they sell in 2m lengths, have offices in most states
