Galil / Configure Plugins>>Galil.... then mach3 freezes
« on: December 12, 2017, 12:28:54 AM »

Hi all,

I have X, Y and Z axis working great on my new flatbed router, using Galil ST plugin, and all DC servomotors and amplifiers.

Now I wanted to add a spindle relay control, and unfortunately for some reason I can not get into the Galil plugin screen to set it up.... whenever I select Configure Plugins>> Galil ST from the plugin menu, Mach3 freezes.  Has this happened to anyone before? I tried resetting the PC, to no avail. Is there anything else I can try before re-installing mach3?

Cheers, Haxby

Galil / Mapping Galil axis to Mach3
« on: February 09, 2017, 12:23:37 AM »
Hi all,

I have found what I think is a bug in the Mach3 Galil plugin.  If I map Mach X axis to Galil X axis, Mach Y axis to Galil Y axis and Mach Z axis to Galil Z axis everything works great. But if I use the Galil Configuration >> Axis setup menu and map Mach X axis to Galil Y axis, Mach Y axis to Galil Z axis, and Mach Z axis to Galil X axis I get some very strange activity:

Whenever pressing the reset button, the Mach Y coordinates change to seemingly random values. If I disable Z axis completely in Mach3 the issue disappears.

I tried this with two different Galil cards, and had the same results. After searching the forums I don't know why I can't find others with the same problem?

I'm using mach3 version R3.043.066, and a Galil DMC-1880 PCI card.

Galil / Re: Galil spindle control (ports and pins)

Ah, well after a sleep, I gave it another crack and it now works. I was trying to associate the galil spindle relay on what I thought was output 1 with Pin#41, but I realised that I was working on the EFGH axis block, where the actual relay output is number 9, and the associated Mach pin number is #49..... All good and working now!

Galil / Galil spindle control (ports and pins)
« on: June 08, 2016, 02:25:39 AM »
Hi all,

Well I have been making progress on the CNC build. I now have the galil card working well with X,Y,Z axis, Mach3 and CamBam. But, I have spent all day trying to get my spindle control working.

It's just simple on/off control that I am after. I have a relay on the galil card's output 1.

I'm confused with the Ports/Pins inputs and outputs nomenclature, there is also mention of M3, M4, M6, M7, no idea what that is.... The Mach3 Galil manual says output 1 = Pin#41. but does that mean GALIL output 1 is referenced by Mach3 as Pin#41? or something else?  I think I have tried every combination within the ports & pins tabs........ Pulling my hair out here! ??? ??? ??? ???

Galil / Re: "galil card not connected"
« on: March 08, 2016, 07:00:39 PM »

OK I found the Config>>Config Plugins menu and selected the Galil card I'm using. Still not sure what the difference is between the Galil plugin and the Galil ST plugin, but making good progress now...

Galil / "galil card not connected"
« on: March 08, 2016, 01:01:39 AM »
Hi all,


I have registered a Galil card (DMC 18x0) , set the PID parameters, and can move motors with it using the DMC terminal, servo design kit, etc, but when I open Mach3, it says "Galil card not connected".

I only have a Demo copy of Mach. Is that the problem?

Also, on startup it asks which controller to use: "Galil-st-Barker......." or "Galil-Barker......"    what does the "ST" extension mean? I downloaded both Galil Mach3 plugins. But what is the difference and which should I use?

In the PDF instructions it says to configure the plugin and there are screenshots of the settings. Where do I find these settings specific to the plugin?

Thanks in advance!

Thanks tweakie. I am not after full on kinematics. Just a basic 2D version, which I think can be done using the "Formulas" input of Mach3.  Maybe even a script to change the G-code before feeding it into mach3.

I'm not sure if I am explaining myself properly. The lower arm motor and the upper arm motor would be routing the X and Y coordinates of the G-code. The Base of the robot would move the spindle in and out of the flat (2D) workpiece..... The work piece would be in place vertically........ so hard to explain this without a video! I might try to animate what I want to do to explain myself better.

Hi all,

New member here, and first post!


I have a large spot-welding robot that used to work on a production line at a closed down car factory. See attached. I have connected new servo amplifiers and resolvers to the motors, and have installed and tested my Windows XP PC with a Galil motion control card. I have tested all the (5) axis and all the hardware is going well. This has been a lot of work so far, as I received the robot with no instructions, no manuals and no controller or power supply! So the next step is to get it to mill something...... 


The easiest way I can think of using the robot is to use the rotating base as the Z axis, and the two arm motors for the X and Y axis. (do you follow me so far? The "X Y Table" would be vertical) Think of a SCARA robot. That's basically what I need to do.... The X and Y coordinates have to be translated into A and B coordinates of the two motor arms.

This would be to cut 2D cuts into say MDF with a router..... So I wouldn't be utilising many of the robot's full capabilities, but you gotta start somewhere....



I wonder if anyone has any experience using formulas to do this?


Another less convoluted way of asking the same question without my specific complicated details, is whether anyone has ever used a SCARA robot like this for instance http://www.directindustry.com/prod/adept-technology/product-6076-153983.html, and had any luck using Mach3 formulas to control the two motors to follow a standard X Y router table.
