Still need to get Teflon washers for motor mounting and pivot points. Also wiring need more tiding up and most probably all of the MM need another coats of paint :) Thanks for looking, Anil

great work

I like Red and White.

Thanks Sharma, I hope its allowed :)

Here is final piece, the Z-slide mounted, I was waiting for the motor for Z but couldn't resist and mounted the old round motor for now :)

And now back to control box and wiring.

Almost there
 

After encouragement from fellow member, decided to post pictures of my control box (Biiiig one :)).

Green is power indicator and other 2 red are to indicate 2 relay outputs, spindle and dust collector.

Transformer has 3 tap so that motor voltage can be tweaked.

Plate where all ground wires terminates

It look fine except bad paint job done by me as usual :)

Nicely going ANIL….
It sure looks like you’re very close to a rolling day!
Wishing you all the best and a smooth final tuning !!
Amicalement, Robert ;)

Cool man !!!
Now start making dust and get first 2010 #

Good Job ! Take care to have the control box cleaned out of any wire pieces lying around, thy make beautyful sparks!!!
Happy New Year!

Thanks Robert, Sharma,

Hope to qualify for first # of 2010 :)

Right Claus, it gets a vacuum cleanup after wiring done. Wish you and all here a happy new year.

MM Logo
 

Wishing all at MM forum a Happy new year 2010 :)

Got Logos printed, will paste them today and do a pen test as I don't have spindle/router yet.

Go Roaring Anil. All the best. Happy New Year to one and all at the Forum too.

Way to go. Lets see those pen marks!

Its moves :) :)
 

My telephone (internet) was down last few days and could not update.
After pen marks (in first pic, those marks are supposed to be roadrunner :)), I moved on and installed a die grinder I had in place of spindle and finally it makes dust..

First few final shots with logo pasted

Z-proxy is mounted directly on spider plate, a bit off center, It works fine.
Attachment 7995

Quick change mount works great, and here is die grinder in place..

Attachment 7997

Broken my first router bit in MM, my mistake instead of typing -0.1, typed -1.0 for the Z and the machine happily plunged exactly 1 inch without a strain :)
Attachment 7998

Now using a broken drill bit for testing :)
Attachment 8001

And look at the dust, huurreey...
Attachment 8000

Here is closeup, size is approx 12 inch, rapid 400 ipm, feed 50 ipm, broken drill bit approx 1 mm.

Yippie !!!:D:D:D
Congrats for the first MM # in 2010 !!!
Nice Carvings...

Thanks to Gerald, Claus, Leo, Pady, Irfan, Robert, Sharma, Chopper and all the members for looking at my build, not good looking but it works :D:D:D

I'm sorry if I forgot to mention any names, no disregards please :)

Well done Anil!

Great job Anil! Congrats!

Thank you Gerald for the #44 :D
Thank you Ken. Need to do the PCB for BoB today as I am still using my handwired board.

Well done ! I presume you have the same feeling when you see that monster who was a few month ago just some metal bars, wires and now is moving.

Anil

Congratulations on #44.

Isn't feelings are such that when we see newborn ?
Congratulations on first #2010
Welcome to growing Indian MM club.
And don't worry about broken bits, now we have good (cheap) source, don't we ;)

Well said, the feeling is exactly same :)

Congratulations Anil! :)

Well done Anil...let the real fun begin....

I am very happy for you Anil. You have done a great job on your machine.

Enjoy , and well done Anil

Thank you Kobus, Leo, Heath, Hennie and everyone, I got ideas for executing bits and pieces from almost everyone's thread :)

Félicitation Great for you 1 instead of .1 not as bad as 5 instead of .5 happy pole vaulting

Anil, Congrats! Great work, and done really quick too.
So #33 and #44 are in India. Perhaps someone here
will get #55 too :-)

Do post some technical details of your homebrew
driver board and BOB.

Nicely done Anil, congratulations on #44.

Thank you Wayne.

Thanks, Pieces keep on fitting in as you move along, its a nice design just get started and in no time you will be moving fast :)

I am doing a controller board for managing all inputs from proxy and switches and redoing the BoB to add an intellegent charge pump (uC based so that it never missfires on noise) and including a PWM to 1-10V for spindle control from mach on same chip.

I'll update as soon as I test them and send the design/code to anyone interested.

Anil,

I was thinking the same, however would not a simple bandpass filter be enough? Then EMC2 or MAch3 just needs to put out a specific frequency.
That said, I am not sure how the current implementation is of the CP on the PMDX122 is, does the flip frequency matter?

I did notice that EMC2 puts out a very low (2-4hz??) frequency for the CP, I am not sure what will happen if that is increased.

Ries

Update Builder's Log
 

Anil,

Great build and a wonderful job documenting the build. :) Congratulations on Serial #44, the first Serial # of 2010 just as you had hoped!

The Updated Builder's Log is here.


Please let me know the "cutting" dimensions of your MechMate for the Builder's Log. Also, please review your entry and provide any changes you would like.

Thank you, I was just waiting for you :)

For log cutting dimensions are 2500x1220, Entry look fine, if you can please update the comment section as "Belt reduction per Chopper design, DIY Drives & BoB"

BoB yet to be completed as PCB is not yet ready but right now I'm using a DIY handwired BoB.

Thanks again

Ries, A small 8 pin uC is cheaper than few passive components :) moreover think of this as a band pass digital filter with added hysteresis. Hysteresis can be smaller for ON and a bit longer for OFF so that a glitch in CP pulse train don't send a stop signal.

For PWM to 0-10v conversion, of course a simple passive network will do and that's exactly I am thinking of doing.

I'll do some testing on both and post the results.

Updates completed, here.

Again, great job, Anil.:)

Anil,

Like "quadtech",

I'm also interested in additional details of your DIY drivers and BoB. I'm familiar with the AVRSTMD.COM site.

You mentioned Gerbers. Would you be willing to share your Gerbers?

John,

Don't know if I should post the files here so I am PMing you the Egale files for the Drives, Change as you like and generate Gerber or anything you want :). Fell free to ask if I missed anything. Download free version of Eagle, the PCB is within the limits of free version.

I'll post my version of BoB with CP and PWM as well soon. Also there is a controller board that rides on gantry for taking inputs from proxy and buttons in progress, will be done and shared soon, thanks for the interest.

As the real work is done on weekends so my progress is slow :)
