a little progress
 

Thanks Sergio
then i will try it today and see if i can get it to work
the machine start to look like a machine, picks to follow:

Hi Selbuss,
nice progress with your machine. Please let us know how your combo of smoothstepper pmdx 125 and 107 work together.
Is it possible that the link you stated above should be www.hossmachine.info and not .com?

Greetings

Hi Claudiu
Yes you are rigth it is www.hossmachine.info
and i will come back when i have tested it out but i have to cnc my new machines from China too, first i take them apart and adjust them and it was fun to operate them when they was but back together
so now i do electronik for tre machine at the same time here are some pics:
Now i can make my own part for the MM

Jealous I am. :):cool:

Me too...please sir adopt me ;)

Hi Selbuss
nice work i've already have the same stepper motor but the dual shaft ones . i will connect them a bipolar parallel i've bought a PMDX-106 not the 107 one . how is your success with the pmdx-107. i won't buy the chinese VFD , i will go for delta one.

hi myousry

im not finish with my electronic and i will take time to read what i can abouth the object since i am new to this
my motor i go unipolar half coil in the beginning and see hove it works
my choice of the 107 was because i use PMDX-125 and they recomand it
my controlbox was to small so i think i use 2 controlbox one for the trafors and VFD and one for the electronicks
The smootstepper is not show on the pictures since i had not get it when i took the pictures
Have played with the smootstepper and BOB and ewerything work so far
but have not tested the motors and VFD yet
Have built electronicks for the X3 mill and C6 lathe from a G540 and tested it all works fine
Yesterday my new engine and and automatic transmission for the Buick arrived so i have to work with the car also;)

Hi Erik

Just a reminder since you are using the PMDX-125 as i am.
You are going to need a fat cable running to the y-car for those inputs,outputs...etc.
The reason is that in 125 the inputs don't share the same gnd as it was with 122 so every pin must have it's own gnd.
That means for 11,12,13,15 input pins you need an 8 core cable, adding the PMDX E-Stop and 1 output you find yourself with a 12 core cable, which by the way is what i used in my configuration. :D
Plan ahead for those I/Os when you come to the wiring cause you are going to need lot's of them.

P.S. Forgot to tell you that the 125 has also 2 relays J9 and J10 with 10 and 30 amps so it's a good idea to use them for saving some extra money for fancy SSR's and other relays.

i Sergio
When i tested it to day i can use the same gnd for 11,12,13,15 works fiine at my 125
but when i started up my spindel today at low speed i hade a scriming noise from the front bearing and it got varm after 20 sec
had a little problem with the 107 to get it to work but i manage at the end,
so now i have to dismantel the spindel for inspekting the bearing but i dont know hove to take it apart yet, i try to google it to see if someone have done that yet
as far as the test with the smootstepper+125+107 went well

Check this out.

there are some photos, maybe helpfull to you.

Selbuss can you enlighten me? what is the use of the PMDX 108 (not sure if yours is input or output) used in combination with the PMDX 125 ? it adds extra pins? Im confused :) I already purchased a 125 and now Im not sure if I need the 108 or not.

Thanks!

hi Pablo
i bay the 108 input to get more buttons to play with when i make my controlboard
i want to use the MM without the computer if i can

hi selbuss i need a favour from you. could you check up the inner body of the spindle regarding the kind of metal that contains the water coolant system whether it's aluminum or anything else as there is a very important matter regarding the corrosion of the coolant system since your dismantle your spindle
thanks a lot

hi selbuss
by the way how are you going to cool your spindle by using a simple pump and buckets
or by using a radiator, reservoir ,and a pump

utdate of the spindel
 

I had to make some tools to take the spindel apart and after that i find that all the screws wer cut off that hold the backing plate so the plate follow the spindel when it rotate,luckely i dont run it more than a couple of sec. before i stop.After some strugling i get out the rest of the srew and the chinese srew was as soft as butte so i change it to hi grade srews, at the beginning i was afraid that the srews i put on was to hi head on but after meshuring the higth between the srews and the motorwindings i had 0.7 mm clearens so it was ok.
So now i have tested the spindel and all work OK.

Since i dont get the gecko when i order my drives i had to take a picture of one in live HE HE

Selbuss, care to share the bearing number?

hi Ken
yes i send it to morrow, have it on the computer at the workshop,
some china crap but i use it for now and bay new when i i go Bangkok

Hi Sergio,
Here is the feedback I got from Steve Stallings at PMDX:
"The extra ground pins on the J11 and J12 input connectors of the PMDX-125 are for convenience. They are all the same ground and you could use a single wire (core) to connect all of your switches back to the PMDX-125 board. The E-Stop signal can also share this ground, but I personally like to a dedicated ground for E-Stop for
the sake of clarity.

The output signals on J5 and J6 use PCground and this may not be mixed with the isolated ground on J11 and J12. This is implemented the same as the step and direction signals, that is, we are expecting the devices connected here to have their own signal isolation, or to not need isolation, for example a solid state relay.

The relay outputs on J9 and J10 are fully isolated and none of them are connected to any ground circuit within the board."

I'm just hoping it all starts to make sense when I get the parts :(

Spindel bearings
 

hi Ken
Sorry for not give you the bearing number before, but have bin buzy
The front bearing (2 pcs) have this nr:

H7005C TN1-2RZ UTE 09111305-1

and back bearing 1 pcs:

B 7002 CETA-RZ

Red

You are right ! :D

What got me confused about the J12 gnd is this from PMDX-125 manual :

"6.0 Input Signals
6.1 General Purpose Inputs

.....Mechanical switches can be wired directly between the input pins on J11 or J12
and adjacent GND terminals.

.....WARNING - The PMDX-125 inputs are optically isolated from the PC-side ground.
The terminals on J11 and J12 marked "GND" are NOT the same ground as any
other connector on the board. Connecting any "GND" terminal on
connectors J11 or J12 to the "PCgnd" terminal on another connector will
defeat this isolation"

Also the thing that J12 GNDs are not having any continuity with each other
made me think that each GND has to be connected to it's adjacent pin.

So far no smoke
 

hiSrgio
yes i tested it and it worked out fine but i forgot to think of the E stop have two switsh so i get short on one wire so now i have to put another wire for the proxy sensors so i have one spare for z zero if i need, i also get short on cabel for the spindel, this i find out today when i start to connect the cabels, i dont know wher i was thinking but its not a big deal the only thing is i have to go Bangkok to get it but my friend com on the 23 this mnds so i have to pic him up and then get more cabels,, i have get my motors and bob drives for my mill and lathe so they need cabels too
here some pics so far::D

Erik

Very nice !!!
I like the color even if it isn't blue.
Your machine is looking great you are almost there.
BTW did you manage to control your Huanyang with your 107 ?
And if yes can you post your connection diagram ?

Sergio

hi Sergio
Yes i get my 107 up and go with my bob125
i will send you the diagram when i get to the workshop
my two biggest problem now are the fittings for the water cooling at the spindel and the
gas spring, can not find anything that match to use ,
the fittings i think i metrics about 10mm or so and the gas spring have to travel 350mm
the nearest i come was a travel of 200 or 550mm but that is to big, so if anyone have order a car gas spring or now the car that match please give me a mail

PMDX-107 to VFD
 

Sergio
here you have the diagram i use:

Thx a lot Erik.

I think i'll give it a try with the 107 since i can't get my RS-485 to work with
my VFD.

What settings did you have to change to get the 107 to work with your VFD. I have a 106 and all I can do is spindle on/off, no speed control. Any help would be appreciated

What bob do you use?
i use the PMDX-125 and first i check that the 107 get the signal and measure out that it regulated the 10 volt to the 107 then i hooked up the VFD as my drawing in post #64 and then everything work OK, i don't have the same speed at the VFD as i have in mach3 but it only different 20 to 40 rev so i think its ok, maybe your setting in the VFD is wrong i had some work about that in the beginning and don't remember what setting that make the problem but i can send you the settings if you need it, just now I'm not at the workshop so i don't have it here,

New pictures
As for now my machine is up and working, at the moment my camera is not working and i wait it back from the dealer but things take time her in Thailand and i have waited for over one mnd now but i get my SD card back so i can post some old picture

I got it working sort of. It turns the spindle on, and changes the speed, but the set speed is nowhere near the speed the spindle turns. The changes you made to the vfd settings and the mach 3 settings you are using would be very helpful!

Thanks in advance

ok i see if i can get it to morrow, i dont remember the settings right now, but it has to do with the calculation between speed control and VFD

try to hange PD144 Rated motor revolution to 3000 - (when you multiply this 3000 by the Min voltage of 8, you get the top speed of the spindle - 24000 revs.
thats all i have for now
