OK below is a link of my converted cnc lathe:
http://youtu.be/Ws-0u15YJxE
Got some tuning issues here, when I run Gcode from Visual turn, the movement is not 1:1, but when input let say G0X0Z100 @ MDI, the Z axis does move to 100mm.
The DC motor encoders' are 1000 lines.
For X axis: both gears are T22, which is 1:1, so step per = 1000 x 4 (1000 x 4 for quadrature) =4000/rev.
1 rev = 5mm therefore 1mm = 800.
Currently the X step per = 33 not 800. If I use 800, the X axis would exceed travel limit...
help..
-
What drives are you using? Could there be electronic gearing in the drive so that one pulse sent from Mach could be seen by the drive as X amount?

Hi Hood,
I'm using this drive:
http://www.leadshine.com/Product_Show.aspx?ID=79
Ok I thought this drive do not have electronic gear ratio, the stepper driver from Leadshine use dip switches for micro stepping so I thought the DC servo drive might have the same for electronic gear but not.
-
It does according to their specs on the page you linked to, see screenshot.
Hood
-
Thanks Hood, will do the tuning tomorrow.
-
I had a look and there is a setting in the software for the gearing, you will just be wanting 1:1 likely.
Hood
-
Sholdn't 1:1 be the default setting?
Installed Pro tuner, but can not connect between the DC servo drive and PC due to bad connection RS232, the PCIe RS232 card from Uptech.
Need to sort this out 1s.
-
I switch to another PC which has a RS232 on board, got connection between the drive and pc and here is what it looks like:

I chaged the value of CAM_numerator: 1 to 8, CAM_denominator:1 to 3 then start....
I'm still suspecting the cause is Visual Turn not the tuning....
-
The setting should be 1 and 1 if wanting un-geared input. Easy way to tell if it is CAM or Drives is command a move via MDI. If you zero the X DRO then command a move such as G0X20 then the X axis should move to that point. I will assume you are set up in Diameter mode so with a X20 move commanded the X axis should move 10mm (I think you are using metric units?) If set in Radius mode then the axis would move 20mm.
Hood
-
For the DC servo drive I didn't change the value so it still CAM_numerator = 1 , CAM_denominator = 1.

In MDI I typed G00X-10Z0, then watching the X axis travel toward the stock direction by 10mm.

I also included a gcode output from Visual turn.
-
Remember I said the Step per was 33 at the beginning of this post, I realized Mach is causing it, so I re-installed Mach3 just before I uploaded the pictures in the last post.
The Dc servo drives are ok, I think is the software that is causing the problem, could it be the Mach3 post processor in VT?
I will try this tomorrow, open a example file in VT (Visual Turn), the file is in inch, change unit to metric, then scale it up the diameter of the part from 7mm to 50mm:
http://youtu.be/WF1sAixhQMY
-
Ok if your X axis is moving 10mm with a 10mm command then you have Mach in Radius mode so you will need to make sure your CAM is set to radius mode. Personally I prefer Diameter mode.
Your code attached above is in inches, I think you said your machine was set up in metric. If so you would be better trying to get the CAM to use metric.

"will need to make sure your CAM is set to radius mode"
mm..ok, will look into that.
Yes I use metric only. I have attached a new Gcode file, would you mind have a look at it see if it is in inch or mm?
thanks,
-
That one is metric, you can see that by the G21 at the start, the previous one had G20.
Hood
-
Ok, I got an reply from Mecsoft:
1. Make sure the scale factor for X coordinate under the Motion tab in your post processor is set =1 to output in radius mode.
2. G20 represents output in inches and G21 for MM. You can change this under the General tab in your post processor.
To edit the Mach3 post processor, select Post Process from the menu bar in VisualTurn and click Post Processor Generator. Select the post from the list and click edit.

Is all tuned and running!!

Couple of things, first regards the shape circled in red. Dont worry about that it is just the way Mach Turn displays the part, it looks at all feed moves and thinks they are within the part. Normally Cam would have rapids close to the end of the stock (to your designated start point) but looks like yours may be using G1's.
Ok the second thing, yes your spindle does seem a bit slow.
Third, I suggest you programme in feed per rev (G95) rather than feed per minute (G94) It is the normal way to do things on a lathe and it means you will always be feeding at a suitable rate even if you call a slower/faster spindle speed. Normally on my big lathe I will rough at 0.3 to 0.35mm/rev and finish at 0.15 to 0.2mm/rev (depends on nose rad of the tool) My lathe is quite solid and has a hydraulic chuck so the roughing is no problem. On the wee lathe I would likely be roughing at 0.2 to 0.25mm/rev.

About the G94 G95:
(http://i1204.photobucket.com/albums/bb407/cncfreakcncfreak/BVB25L%20cnc%20conversion/G94G95-2_zps61ca08cd.jpg) (http://s1204.photobucket.com/user/cncfreakcncfreak/media/BVB25L%20cnc%20conversion/G94G95-2_zps61ca08cd.jpg.html)
My current setting is as above.
-
Thats scary stuff there ;D
Thankfully it seems like your post processor is not putting in the G95 (It should) as if it did you lathe would take off at max rapid and try and do its cutting. What you have above is for every revolution of the spindle the axis will travel 800mm.
When doing feed per rev it will be a fraction of a mm you want your feed set too, as I mentioned in my previous post.
Hood
-
How do I tell if G95 has been output? will it show in the first line of the Gcode?
"What you have above is for every revolution of the spindle the axis will travel 800mm.
When doing feed per rev it will be a fraction of a mm you want your feed set too, as I mentioned in my previous post."
so are you suggesting to change all 800mm/rev to 0.35mm/rev?, like this:
(http://i1204.photobucket.com/albums/bb407/cncfreakcncfreak/BVB25L%20cnc%20conversion/035mmperrev_zps36c6cb1a.jpg) (http://s1204.photobucket.com/user/cncfreakcncfreak/media/BVB25L%20cnc%20conversion/035mmperrev_zps36c6cb1a.jpg.html)
-
That programme has a very unusual strategy for calling feeds. Normally you would just have a feed to call and the programme would do all non-cutting and non-approach moves automatically as rapids. You don not seem to have that choice as such, you have the choice of rapids for Tf but not the others. You can obviously put a high value in them and Mach will treat them as rapids though.
Anyway I would suggest you try 0.3 Af, Ef, Cf, and Rf and possibly have large numbers entered for Pf and Df and leave Tf as Rapid.
Make sure you cut air for the first time to make sure it is working as expected.
Also the code needs to have a G95 near the beginning and it will also be a good idea to change Mach to default to G95, that is done by adding G95 to the Initialisation string on the General Config page of Mach. If your post processor does not put out G95 then it would be a good idea to get it to do so, that could possibly be done by you or if you dont know how to edit the post processor in your CAM then ask the vendors to do it for you.

Sorry for the late reply.
As I was testing the code, the Z axis belt came off, still fixing it, will probably re-design the Z a xis motor mount.
I tried 0.35 mm/rev, but it was a bt too slow, then changed it to 100mm/rev which seemed to be ok.
-
You were obviously not in Feed per Rev mode (G95) or 100mm/rev would not be slow ;)
If that was the case then the axis would travel 100mm for each revolution of the spindle.
One thing I should ask, do you have an index pulse set in Mach so you can read the spndle speed?
Hood
-

Hood
I don't think so, is the Index Pulse set in General config?
Another thing, when you said : If that was the case then the axis would travel 100mm for each revolution of the spindle.
100mm for each revolution of the spindle, it sounds like the spindle is synchronise with the X and Z axis, is it?, cos currently the AC servo spindle is in speed mode. I'm thinking to add it to A axis for threading when all systen is stable.
-
The index pulse would be input to Mach on an input pin then you would tell Mach which pin by setting that up in Ports and Pins, Inputs.
If you do not have an index connected then that may well be your issue with the very slow feedrate, if you have "Use Spindle Feedback in Sync mode " chosen then Mach will not see the index so will not feed very fast. If you go to Config menu, Ports and Pins, then Spindle Setup you will see that option top right.
If you do have an Index input and you tell Mach to use it in sync mode then the axis will not be truely synchronised with Spindle. What will happen is each time a feedrate is called Mach will look at the true RPM and feed accordingly. If however the spindle speed drops/increases (spindle override or due to load) then the axis will not change its rate until a new feed is called, only then will it look again at the true spindle speed and adjust the feed accordingly.

Ah! I get it. So this is what Index about:
http://tetralite.com/lathe/spinsensor.html
Basically add an encoder to the spindle, but since my spindle is driven by an AC Servo Motor can't I use the signal from the AC servo encoder as feedback or do I still need to add those sensors at the back of the spindle?
-
If you are using the parallel port then the encoders index will be too short, you would either have to electronically stretch it or use similar to your link. If you are using an external controller then likely it will be fine with the Index from the encoder.
Hood
-
I decided to use an encoder for Index pulse and input to MAch3.
I have some spare Rotary encoders dunno if this is suitable for this application, encoder brand = Omron E6B2-CWZ6C

http://www.ia.omron.com/data_pdf/data_sheet/e6b2-c_ds_csm491.pdf
Other Rotary Encoder brands like US digital single ended have 5 pins, A,B, +V, -V and 1 index pin. For Omron I'm not quite sure if "out Z" is the same as Index in US Digital's encoder, any idea?
-
Ok I think I found the answer for Z in cnczone. It is index pulse.
-
Are you using the parallel port or an external controller such as the SmoothStepper?
Hood
-
I'm using SS, USB.
-
Ok encoder index will work great. I would suggest you connect it to Port3 as they are likely a bit faster seeing as they are intended for encoder input.

Assigning Pins:
A-Port # = 3
A-Pin #= 1
B-port # =3
B-pin # = 2
As for Index....
-
As far as I know the SS does not support full encoder input for syncing Z to spindle so there is no real benefit of connecting the A and B channels.
You do however want to connect the Z signals, if it is a differential encoder then connect Z+ and Z- to the differential pins on port 3. You then go to Ports and Pins, Inputs and scroll down to Index and enter Port3 and whatever pin you have the index connected to.
In Config, Spindle Pulleys you make sure you have your Max and Min speed set and also set the ratio to 1 (assuming encoder is direct connection to spindle)
You should now have spindle speed readout when you command a spindle rotation (M3 or M4) The Index will also be used for lathe threading.

This came to my mind, If M03/M04 is called it won't start the spindle Automatically because it is using a Variable speed controller connected to CN1B, If I take the CN1A step and Dir wires to SS port 1 Pin 8 & 9, what else do I need to configure in order to make it spin when M03 command is called?
-
What is CN1A and CN1B?

Yes, definitely set it up as Step/Dir spindle, it will work much better with one exception. Spindle override with the SS/ESS and Step/Dir spindles is not perfect, unless it has been sorted recently, I waited for 3 years but it never got done and I have now moved on. With a light spindle you may not notice the problem as it is not nearly so noticeable on my mill as it was on the big lathe. Other than that however it works very well.
Hood
-
What is SS/ESS?, what do they stand for?
Found this:
http://www.machsupport.com/forum/index.php?topic=21036.50;wap2
-
SS means SmoothStepper and is usually said when referring to the original USB SmoothStepper.
ESS means Ethernet SmoothStepper.
Regarding the quadrature spindle output, it made no difference on my machines so I just dont use the spindle override on the two machines I still have the SS and ESS on. I have a further two machines that have CSMIO/IP-S and IP-A controllers on and I can use the spindle override pot on these machines with no problems.

I wired the cw & ccw of MRJ2S-350A's CN1A to SS today, it is now in step/dir mode. Will set the Pr tomorrow.

Ok, there was a slight problem with my homemade board;

when MRJ2S CN1 connected to this board it does not correspond, but it does on another system, so I'm sure something is not right with the board, will re-build a new board with my Direct PCB printing epson T22:
http://diydrones.com/profiles/blogs/direct-pcb-printer.
Here is the MRJ2S-350A in step/Dir mode:

and still can not get the AC servo turning, on another Mach3 controller the BOB is a C10 board form CNC4PC and it worked perfectly with SSD (blue squary shape in the middle of the board).
-
What are the blue things?
Is everything else working?
Hood
-
Sorry, is SSR (Solid State Relays) I thought with the new board I would be able to run the AC servo but not.
The board is not the problem, stepper driver wired to this board works, but not the signal out from CN1A(MRJ2S).
Also I get an error from SS when AC servo is powered on and then SS crashed.
Is SS's output signal the same as C10?
-
Are you trying to send the step/dir signals via the relays?
When you say it worked via the C10 are you meaning you had it connected via the parallel port or via the SS to c10?
Is the CN1A not the inputs for Step/Dir or are you talking about some other output from that connector?
Have you set the SS config up for Step/Dir spindle?
Hood
-
I checked some of my previous controller wiring, this one:
(http://i1220.photobucket.com/albums/dd459/happytriger2000/Motion%20Controller/DSC02643.jpg) (http://s1220.photobucket.com/user/happytriger2000/media/Motion%20Controller/DSC02643.jpg.html)
The SS had a C25 Terminal Board, MRJ2S's Amps worked.
Are you trying to send the step/dir signals via the relays?
Yes, the C10 board is wired this way and worked pretty well for MRJ2S so I used the same method for SS, but didn't work.
When you say it worked via the C10 are you meaning you had it connected via the parallel port or via the SS to c10?
http://s1204.photobucket.com/user/cncfreakcncfreak/media/BVB25L%20cnc%20conversion/M4V05950_zps587ff3dd.mp4.html
PC connected to C10 via pararell cable, then from C10 pins 2&3 to MRJ2S CN1A's CW & CCw result = link above.
Is the CN1A not the inputs for Step/Dir or are you talking about some other output from that connector?
Yes this is the input for Step/Dir coming from SS.
Have you set the SS config up for Step/Dir spindle?
I haven't done any changes in config. I disconnected one of the stepper driver's step/dir wires off SS terminals and wired CN1A's cw wire & ccw wire to the terminals and test if it spins, but it doesn't.
-
I certainly wouldnt think it a good idea to send step/Dir signals via any sort of relay, wouldnt even be using any opto isolation if possible as the drives side of things will almost certainly be isolated.

One thing I would check up on is that you can mount that servo drive horizontally, most I have seen said they must be mounted vertically to get proper airflow.

The gantry was purchased as used about 2 years ago, is a 2.8m length, 1.8m wide, small machine compare to my neighbour's 5m long gantry. This machine only for facing, it is not suitable for positioning error is too large (lead screw).
Ill add a fan at the top of that amp some day.

Add a sensor holder:

Ok, Sensor installed, EE-SPX406: http://www.ia.omron.com/data_pdf/data_sheet/ee-spx-w_dsheet_csm474.pdf (http://www.ia.omron.com/data_pdf/data_sheet/ee-spx-w_dsheet_csm474.pdf)
Wire: brown = 24V, Black = Index signal, Blue = 0V
I set the Index Input to pin 10 port 1, how do I determine if there's signal coming in to Pin10? Mach 3 turn no Diagnosis tab?

Check the wire connection, the Index terminal was connected wrong and has been corrected and previously the 0v wire is not wired to BOB's com (gnd), Index pin is flashin in Diagnosis.

Ok, I have been thinking a lot whether to use my servo drive in speed control mode or position control mode for spindle?
If I use speed control mode then I can use my spare C6 from cnc4pc to feed 0-10VDC to MRJ2S drive like this:
