For posterity's sake, I ended up buying an SI-5 isolator board for my KBIC-240ds. I bought two PWM-to-analog converters, and both featured no optical isolation between all grounds. If you want true isolation (which you need for the KBIC-240ds), it seems that you need to buy this separate component or some sort of dedicated device that gives you galvanic isolation. My spindle seems to be working quite well currently.

Hi,

I have a 5 axis homemade machine xyzab...I get gcode from CNCToolkit in Gmax....works pretty well other than tool offset...My linuxcnc is set up in Trivkins...My questions..  I believe there is a 5 axis configuration...

Is it very involved to switch?

Can tool diameter offsets be used?

Would it be better to try and modify CNCToolkit post to use tool offset? 

I am going off a surface...x y offsets I can draw...the biggest issue is allowing for tool diameter in adjusting z axis for b movents.

Thanks for any help!!

Ok, that icon means 'no layout' - makes sense for an indeterminate user layout.

But, sadly, no longer suspicious

Back to stumped.

Had another go at it after updating again.  Here's what I've found:

• qrc file issues are gone.  No error message that the qrc can't be found - that's a win.
• Created six hal LEDs - 3 in main window user tab, 3 in sidebar user tab
  • All six LED hal pins are present in halshow - still good
  • main window user tab LEDs are displayed
  • sidebar user tab does not display LEDs or anything else (Qlabels)

Poking around in the editor, it looks like the sidebar user tab selector button is linked to "page 3" of the stack widget, which should correspond with the 4th page (page-0 being 1st).

When selected, the user sidebar tab is empty, so I think that confirms the right stack page is being selected, but the user ui file isn't being loaded.

No error messages in terminal during startup, and I didn't change any file names or paths from the templates.

The only thing suspicious I can see is what looks like an 'inactive' icon next to the sb_page_4 object in the object window.  Or I'm misinterpreting the icon - not sure. 
 

I guess embedded Youtube links or links to open the video in another tab are the two working options.

Dear Colleges  

Recently I get a junked EDM machine,  this is a robofill 200 I guess charmiles
The machine mechanically is complete, but  the control send a lot errors. I ask to person that know itit and say this machine was good, but now is old and obsolete.

 So, I am thinking this is a good chance to use LCNC and make it back to work again,
 but I will need some help to go work in this direction.

I understood the EDM 5 axis control on the motion axis topic, that is really similar as a foam 5 axis cutter,
This have 5 axis . X,U, Y, V, and Z, Looking deep on this machine,  
I found that the motors can be replaced easily for a new ones I guess some mounting plate will be need to make ti adapt the new servos

My first question, Is about the motion group what technology to use? 

The old and reliable Mesa card + pulse and direction servos
OR
Ethercat AC servos
 Or 
ethercat hybrid steeper motor?
Please advise what technology can be fine

 My Second Question, I found linear scales form heidenhain I found by part numbers that are analog linear scales and after goes a module and after to control, I wonder to know If LCNC can control this linear scales 

My 3rd question, is About the pulse generator that is new for me, I feel this is like the torch control on plasma cutter , but instead control the height , that control as adaptive feed to avoid  machine  breaks the cutting wire. Well over this topic I do not have a clue yet, I been reading some documents , so now I start to understand how it works but now I would like to know if I can control this pulse generator or not. Or if need to find another one that helps me to complete this topic about the pulse generator.

My 4th question, is about the wire spool control as well what is better, normal motor,AC servo or hybrid stepper motor 1 or 2 motors , wire tension control. 

and about other stuff like pumps and etc. I think they can be controlled easily.



 Please advise

Edit: i got it. Just rename the file from arduino-connector to arduino with loadusr -W arduino and it works.
 

Yes, it works, but is not solution.
I remember that program name must be the same as component name, so if component is "arduino" the program must be "arduino" too.
But "arduino" is bad name, because is widely used for many things, so it should be renamed to unique one.
 

I just fixed the qrc file request also was a bad path between apt and pip install methods, now resolves for both so that should not be an issue anymore.. thanks for bringing this up!! was hidden from me with dev pc.

Just had this happen today. Running along just fine, 2 hours into the job and then the End Mill snaps with about 5 minutes to go. What I would like to do it is:
 
1.Pause
2.Stop the spindle
3. Jog to a place where I can change the end mill
4.Touch off again to set my Z
5. Resume the job where it left off (or even better back up a few line of G Code)

Is this possible?
Thanks,
HH

Note that there is a re-write of Halshow under development, it might be worth seeing if there is scope for adding your ideas there?

All those "affordable" 5-axis machines marketed seem to be kind of a scam. Machining extension for the mentioned CAM program costs (AI info unverified) 3200$ per year.
Rarely a real 5 axis machining is shown. My suspicion is that most of the few examples are show pieces which took a lot of effort to prepare.
For the Statue due to lack of CAM I would probably do some 2.5D setups and use the rotary axis as positioner rather than as a fourth axis.

I'm trying to use LinuxCNC_ArduinoConnector V2, but it's not very clear how to install this new version. I initially used install.sh, then loadusr arduino-connector, but an error appears. I included the instructions in the hal and ini files, but nothing happens when I run linuxcnc.

At some point, we will see true simultaneous 4th (and 5th?) axis CAM that is affordable for amateur use. I use Fusion myself and it supports "3.5 axis" toolpaths ie indexed or wrapped 4th axis, not true simultaneous 4 axis. Fusion does actually support simultaneous 4th but for access you have to cough up for the ludicrously expensive "extensions".

I've seen a few of these 4 and even 5 axis desktop machines being marketed (Pocket NC, Infimaker, Makera etc), yet I've no idea how you would be expected to create toolpaths of your own. Does anyone know?

Looks as if Freecad is in the early stages of developing 4th axis. That may be our best hope in the medium term.

1. fix bug in last side tilt angle  2. punch a ridiculous number of holes around the edges of the figures in the collection using an external subroutine. (makeholehere.ngc, included in the zip)

1. Mesaflash source was at one time compile-able on an old windows version I doubt that that is still the case
especially for flashing over a serial port. I can dig up mesaflash.exe but I doubt it will run on current windows.

I suspect the easiest way to flash the 7I90HD would be to leave one configuration as EPP or SPI.
(the 7I90HD has dual flash chips) Then set the flash jumper to select this configuration, power cycle
the card and then without removing power, move the flash select jumper to select the serial configuration
before reprogramming the new serial configuration over Either EPP/SPI with Mesaflash/Linux.

2. The UART module is a standard UART on the serial side (but quite different on the interface side
as it has a 32 bit data interface)

3. You can determine the pinout from the source file PIN_SVUA8_8_72.vhd

4. The regmap file has all this information, its a plain text file. Maybe renaming it to regmap.txt will help for windows.
