General Mach Discussion / Re: Tool Change
« on: January 02, 2008, 11:03:30 AM »
So you are saying G43 is modal? I input it at the beginning of every program? That is simple enough and I will try it. The only problem is I have been required to make an "H#" comment for the program to recognize the height change. I cannot get the program to pull in the "H" for that tool without stating an "H#". Other programs I am using pull in all of the information from the Tool Table when I simply type "T#" into the program. Is Mach 3 different?

The problem is when I put in "T1" nothing changes.  Unless...  I have to put in M6 after T1 in order to get the software to recognize the toolchange.  Also, it won't pull in a height offset unless I use
"G43 H#."  It should be able to just use the T1 to pull in the diameter/height offsets for that tool number.  It should also show that there was a tool change (show new tool number in the box) when I just put in T#.  Thanks again.

General Mach Discussion / Tool Change
« on: January 02, 2008, 10:22:06 AM »
Hello everyone,
I'm wondering if there is a way to make a tool change just by putting in "T#".  Right now, the way I make a tool change I have to put in "T1 M6 G43 H1"  That whole string could be done with just T1. Every other control I've used just needs T1 and it pulls in the offset and diameter for that tool.  Is there a way to make this possible with mach 3?  Thanks!

General Mach Discussion / Galil locked up
« on: October 31, 2007, 12:11:22 PM »
I have been testing a Galil system and thought I was close to having it operational. The jog is working, I was able to command position and move all axis, but my X axis was not moving the exact amount commanded. I went to the automatic setup and when I made it move a value of "1" I did not like the amount shown in the window that asked how much it moved so I cancelled instead of accepting. My axis has not moved by command since. I can still jog in all axis but cannot get it to move to a MDI commanded position. I have tried restarting my system, and even chosen an earlier setup to see if I inadvertently set a parameter wrong. Nothing I do seems to  be effective in making it move by command now. Any ideas?

General Mach Discussion / motors turn one way only
« on: October 10, 2007, 07:09:26 PM »
I now have my motor responding to the controller. But the motor will only spin one direction no matter what command I give it. It will spin with the jog or with the MDI command. The speed is adjustable. The motor is quiet. (I have only hooked up one axis to test the system at this point.) I have checked and re-checked my connections and pin settings. Ports are correct. I'm not sure what to check next. I have a Gecko drive and Brushed DC motors with a CNC4PC I/O and am controlling through a printer port. The Mach 3 ran my Galil setup but two axis were reversed. What do you think?

Thanks for your reply.
1) I connected a 5V power supply to the board as per their drawing. (I used an extra power supply cable inside my computer)
I have the unit wired according to the drawing shown on their website at: http://cnc4pc.com/Tech_Docs/C10R8_WD1.pdf
2) The jumper for pins 2-9 is on "output" - this works ok
3) I changed the "Com" jumper to "Com" instead of "5Vdc" -------This made the unit work! Their diagram says to use the 5Vdc!
4) The "Enable" jumper is in position (It came with a jumper out of the box, I never removed it)

Thank you for your help! Now, how did you know to set the jumper to "Com" instead of 5Vdc?

I'm not out of the woods yet. The motor only runs in one direction whethe I give an MDI command or jog. This is a Brushed DC motor and drive..

Does anyone have any ideas?

After connecting to the 5V from the computer power supply on the CNC4PC Model C10 I/O board I now have a constant 5Vdc to the #10 E-stop pin. I have the #10 pin on the I/O jumpered to the 5V pin beside it. Clicking on the Reset icon does not change this voltage. But I am not sure they are connected.
I have enabled the spindle to use pins 3 and 4 for M3 and M4 commands. There is no voltage no matter what command I give the control whether M3, M4, or M5. I think this should change state to either 5Vdc or 0V, correct?

Yes the jog is hi-lited. And the E-stop is solid.
I get 4.2V if I check from the ground pin to a hot pin on my parallel cable (Not connected to the I/O but connected to the computer's LPT1. But if I check from ground on my I/O to the 5V pin I get only 2.2V. Checking the voltage at the E-Stop (Pin 10 in this case) I get nothing whether it is active or not. I have tried "active high" and "active low" on my E-stop, motors, etc. I only have one motor connected at this time for testing.
I have port 1 enabled and also port 1 on the ports and pins allocation.
But...
I am using a CNC4PC I/O board. I have not connected a seperate 5V power supply. I was expecting to get the 5V through the computer cable. I will try connecting the power supply first.
I am not sure why the Gecko boards require the configuration for 5V as follows:

•  The common terminal to pins 2-9 can be ground or +5vdc. The board has a jumper that allows you to select if the common terminal to pins 2-9 will carry a ground or +5vdc. So if you are connecting encoders or proximity switches, you can select it to ground. If you are connecting Geckodrives or limit switches, you can set it to be +5vdc.
 
Any idea why the common would need to be 5Vdc?

• External Enable Pin (EN). The board has a pin that allows you enable/disable all the outputs at once. The board requires +5vdc in the EN pin. If it is not present, it will send all the outputs to ground immediately. You can use this enable and disable your system manually, or you can install an external Safety Charge Pump or other external device.

I am connecting the 5Vdc now. I'm not sure where the 2.2Vdc that is already present comes from unless the 4.2Vdc that is supplied by the computer is resisted to 2.2Vdc. Any ideas?
