Hi,
did you buy these drives new? If so then there should have come with them all the bits to make up the plug that goes into CN1.
Do you have it?

Do you have a soldering iron, a small one? The terminals on the back side of the plug are small but not insurmountable.

Where abouts are you?. I live in New Zealand so its bound to be a long way from you but if you posted me the plugs I could solder them up.

Hi,

Do you think I should try other C34 for delta b2 driver?

I don't know. The problem is that I don't understand what Arturo has done and in particular how the liitle adaptor boards are wired. Clearly he made them to suit but they are still
not plug and play.

I soldered eight wires into the plug that came with the drive, and that plugs into CN1. The other end hooks direct to my breakout board, I don't have any little adaptor board in between.

May I suggest you ask him to give you an accurate and detailed circuit diagram for the little boards you've got and lets see if we cant adapt them to your drives. He may not wish to part
with this information, and I understand why, but if you are going to be able to use the hardware he has supplied then I think hes honour bound to do so.

Other than that I would make my own. In fact I did make my own.

Hi,
what drives do you have? Are they ASDA-AB or ASDA-B2?

Digital Output 5 of the drive is pinned out to pin 27=DO5- and pin 28=DO5+, which according to page 6 of the C34DE-AB manual are hooked to pins 4 and 5 of the RJ45 connector....
but what happens to it thereafter? Does it get hooked to the breakout board or what?

Hi,

When I disabled Estop in ESS configuration input signals, and I jog from position 0 to position X motor will rotate for approximately 2 seconds, after 2 seconds everything freezes (Estopcondition) than after 1-2 seconds it will continue for another 2 seconds.
So it looks like Estop signal is sent from the board in intervals every 2-3 seconds which last for a second or 2.

That is not an Estop condition, once a macghine is Estopped is MUST br RESET before it will operate again.

Which BoB did you use with delta servo and what programming you did on the delta servo ? Maybe I will try to do same programming on mine and try. Or in worst case if you can help me I will just purchase same BoB as you have.

I designed and made my own breakout board. I programmed the drives to suit. I populated the CN1 plug with the wires I required.

The link you provided to the adaptor board is of little use. It does not specify what happens to the servo alarm signal. It does not look like it hooks to the breakout board at all.
The single most important point about using a servo is that it should fault out if  the commanded position deviates from the actual position by my than the programmable 'Following Error Window'.
The servo should stop and the drive produce an alarm output which should Estop the machine. Without the servo alarm how is the machine supposed to Estop?

Hi,

I read that it’s a good idea to have the 110VAC feeding the spindle on a relay and I plan to do so but I’m not sure if the 3 relays available in my C11G are good for this or I should use a separate relay and this I will decide when the time comes. I will post the relevant info here when I start to work on the spindle wiring and hopefully you can give me a hand if you have the time.

Are you using a VFD? If you are then don't try to switch the power (110VAC or 2390VAC) to it via a relay. VFDs have an input for ON/OFF, use it, all it requires is an isolated set of relay contacts.

Hi,
OK I think you have a problem.

One possibility is that as one or more of the servos operate it is triggering a circuit that Estop the machine.

Another possibility is that one or more of the servos is throwing an alarm which triggers an Estop.

What I would o is disconnect any wiring going to the Estop input of your breakout board. That would preclude any electrical interference.
I would also disconnect ALL but one servo.

Until you track down this problem having multiple servos is just adding confusion.

How have you hooked up each servo, in particular is there a servo alarm output which is directed to the BoB?
Did you solder up the CN1 plug? How did you do it? Do you have  circuit diagram of what you did? Note the a Servo Alarm
output can be active High OR active Low, depending on how you program it.

Hi,

I have to press enable again and I can run motors for maximum of 2-3 seconds and Estop condition again.

Then electrical noise from the servos is affecting the EStop circuit. Why?

General Mach Discussion / Re: ESS Disconnects my Internet?

« on: June 25, 2022, 08:44:59 PM »

Hi,
if you follow Warp9's recommendations you would never have the internet hooked to your machine PC nor would you ever have it connected to
a network. The ESS should be connected direct to the PC, not via a router or switch.

If you attempt any of these things when your machine crashes you'll know the reason why.

General Mach Discussion / Re: Selecting Jumpers COM & PULL UP/DN

« on: June 25, 2022, 08:37:53 PM »

Hi,
while the choice of pull-up or pull-down is determined by your hardware its not true that you can set it at will.
Most breakout boards have jumpers that cause a number of inputs to be pulled high (or low), so that the choice you make affects
multiple inputs. If you want one input pulled high but another pulled low, more often than not it can't be done.

I'd recommend that your choice, at least for the outputs, be determined by safety reasons. In particular what happens when when the machine
is powering up, or in the period of time when the machine is powered but Mach is not yet running? What you do not want to happen is the
spindle start up or the machine move.

I presume that you have a relay to turn the spindle ON/OFF?. Then you need to be assured that the relay is inactive, ie spindle off while the machine
and BoB are powering up. Likewise I would suggest that the stepper drives NOT be enabled UNTIL the machine is powered up AND Mach is running.
That is likely to require that the stepper drive Enable signal from the BoB is pulled low, so that at no time are the steppers energised and enabled
WITHOUT Mach being in control.

These safety considerations are likely to determine whether you have a pull-up or a pull-down resistor on your outputs. It may well be that for convienence
that you want a pull-up on a given output to make a pump work correctly say,  but for spindle safety that is not possible, the output must have a pull-down.
Bad luck. Thus for your pump to work as intended you must supply a signal inversion.

Inputs are somewhat less critical.

I posted a picture of my own BoB. I elected to design and build it so that all the inputs (31 of them) are ALL pulled high. Another way of saying tis is that
they are 'sourcing' inputs. That means that the pull-up resistor on each input sources a small current. For the input to be active the switch or whatever
must pull the input low and sink that current. My BoB is all 24V, and it has a 4.7kOhm pull-up resistor on each input, thus the input sources 5mA to each
input circuit. Therefore ALL my input switches must be  low. For example each Limit switch is Normally Closed and switched to 0V. Only if the switch opens,
ie the machine goes out of bounds, does the input go high, thereby indicating a Limit event.

I suppose it is easily possible to have some inputs pulled up (sourcing) while have other pulled low (sinking) but to date I've suffered no problems
with having sourcing inputs only.

Mach4 General Discussion / Re: analog input to file while running GCODE

« on: June 24, 2022, 10:16:10 PM »

Hi,
I wrote an m40 and an m41 specifically to work with Autoleveller, a software utility that probes a nominally flat surface to determine
small deviations from flat and thereafter manipulate the Gcode to follow the contour. I use this for making circuit boards.
The full story about how and why I came to write the macros is here:

http://www.cncsoftwaretools.com/forum/viewtopic.php?f=4&t=336

You will note that the file dialog I used as the basis for my macros is included in Mach4Hobby release:

C:\Mach4Hobby\LuaExamples\ProbeToFile\m401.

The m401 macro is to open a probe file while m400 closes it. I copy m401 here, but you have it on your PC already:

Code: [Select]

function m401()
inst = mc.mcGetInstance();
    -- create the wxFrame window
    mainframe = wx.wxFrame( wx.NULL,          -- no parent
                        wx.wxID_ANY,          -- whatever for wxWindow ID
                        "DummyFrame", -- frame caption
                        wx.wxDefaultPosition, -- place the frame in default position
                        wx.wxDefaultSize,     -- default frame size
                        wx.wxDEFAULT_FRAME_STYLE ) -- use default frame styles

    -- create a panel in the frame
    panel = wx.wxPanel(mainframe, wx.wxID_ANY)--We are not going to show it but we need to have this to use the File dialog

local file = wx.wxFileDialog(panel, "Select Probe File", "", "", "Text files (*.txt)|*.txt|Tap files (*.tap)|*.tap",
                             wx.wxFD_SAVE,wx.wxDefaultPosition,wx.wxDefaultSize, "File Dialog" );
        if(file:ShowModal() == wx.wxID_OK)then
            local path = file:GetPath()   
--wx.wxMessageBox(tostring(path))
--[[
Set the output of the probe points with the format String
Example:
X%.3AXIS_X
will output X<xprobevalue>
]]--
mc.mcCntlProbeFileOpen(inst, path, "X%.3AXIS_X Y%.3AXIS_Y Z%.3AXIS_Z A%.3AXIS_A\r\n", true);
        end

end

if (mc.mcInEditor() == 1) then
    m401()
end
This file dialog will need to be edited for yor purpose. A g31 automatically writes to this file in append mode, but you wish to write values you will
have to write to the file using the formal Lua procedures, and you'll find examples in my m40/m41 macros.
