General Mach Discussion / Please, Help homing my gantry on my router

« on: August 18, 2008, 03:09:49 AM »

I've tried so many combinations that I'm lost

I would like to know what I must do to home it right.

I have two limit switch, one for the X and one for the A axis, both have there own input, port 2 pin 15 and port 2 pin 11 (on diagnostic screen, I can see both led when I manually trigger the switches, it is OK)

If I disable one limit switch, homing is OK but not square

If I enable both switch, homing is ok but look like Mach3 does not see the switch for the A axis. it will not square the gantry

On general config, I try to enable and disable "home slave with master" and this does not work either

I try to edit the RefAll button, with the Refcombination(9), this does not work, homing is good but not square, look like Mach3 does not see the A switch, Act like the DoButton (23) Ref X

One wire of the switch is connected to +5 and other is connected to input of the breakout board (did the autoselect and Mach3 recognize both switches.)

Do I have to Ref A axis separately, what is the DoButton code?

I'm using Mach3 V 3.042.001

I really don't know what else to try after that. I have searched on the forum with no result. Thanks

General Mach Discussion / Stepper motor make a lot of noise

« on: August 14, 2008, 03:52:46 PM »

Hi, I bought 2 of these stepper driver. ( for my double screws X axis)

http://www.kelinginc.net/KL6050WiringDiag.pdf

I also have one CW250 stepper driver (for the Y axis, no noise, run very smooth)

http://cgi.ebay.com/5-AMP-Bipolar-stepper-motor-Driver_W0QQitemZ330247578981QQihZ014QQcategoryZ71394QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

The two from kelingic technologies make a lot of noise.(A loud Hiiissssss)

1- What mean, CP+ and CP- and CW+ andCW-. (I know that this is steps and direction)
    The KL6050 receive step and dir to the minus pin , CP- and CW- (CP+ and CW+ are at 5 volts)
    The CW250 receive step and dir to the positive pins CP+ and CW+ (CP- and CW- are at ground)

Can I swap those connection, try to connect the KL6050(the one that make a lot of noise) and send signal to the CP+ and CW+ pins and ground CP- and CW- to test

Thanks

Note: I have swapped driver to test and it is really the driver

General Mach Discussion / Mach3 freeze with my wireless network

« on: August 09, 2008, 10:46:16 PM »

I have a dedicated computer in my basement running Mach3.

I do all my drawing and programming on my main computer in my workroom.

When a program is finish, I have to copy it on my USB key and transfer it to my computer running Mach3 in my basement.

I have tried a couple of time to connect my Mach3 computer to internet and to connect to my wireless network so I can transfer my CNC program from my main computer to the other.

The problem is as soon as I install the wireless board, Mach3 will not run, the computer freeze, I have to reset it.

They're not conflict in the control panel, tried the special driver, no success, driver test run fine.

I can connect to the internet and surf on the web.

I had to remove this board in order to install the wireless board (No more PCI slot)



I have tried to re-install Mach3 when the wireless board in in the computer with no success again.

I really don't know what to do.

If somebody could help!!!

General Mach Discussion / Laser detector for tool setter

« on: August 09, 2008, 05:15:33 PM »

I would like to install a laser detector with a laser pointer to slow down the Z axis when measuring tool length on my tool setter.

This setup would serve as a switch with mach 3.

I would add to my tool setter macro a function, G0 until laser is cut by the tip of the tool, then go G1 F3.

This would be great since tool are sometime 5 inches long and sometime 3 inches long.

Maybe a small infrared receiver could do the job.

Thanks for any advice, Jeff

General Mach Discussion / How a ModBus work

« on: August 08, 2008, 07:02:22 PM »

Hi, I already have two parallel boards plugged to my computer running Mach3. I need more inputs, at least 10 more. Is a ModBus could do it, How do I hook it up, like I said, can't get more parallel input.

Any good sources to buy, what did you do to get more inputs.

Thanks.

General Mach Discussion / GetVar(2002) used in 2 Vb macro

« on: August 04, 2008, 06:10:39 AM »

Hi

I would like to probe the workpiece on the Z axis with a macro using GetVar(2002) when the probe touch the piece.

Also, would like to use a Vb macro to set the Z tool offset  but can I use something else than GetVar(2002) because since this is the same variable, it change the z axis also instead of the workpiece offset only.

I really want two separate macro, one to probe for G54 and one for tool offset length.

Could somebody explain to me what the difference between "GetUserDro , GetDro, and GetOemDro" -  "SetDro ,setOemDro and Call SetDro"  -  GetVar(2002) and GetVar(1000)

When to use Dro and OemDro, GetDro,          GetUserDro and GetOemDro


This would be greatly appreciated, Thanks

General Mach Discussion / Relationship between tool height-probe height and work offset

« on: August 01, 2008, 12:31:37 AM »

Hi, I have set up my probe with a macro that work pretty well as well as a tool pre setter that work pretty well too.

Now my question is what is the relationship between the table top position, tool length offset and workpiece coordinate (G54)

The macros work individually for the probe and tool height setter but how do I combine both

I have attached a little drawing of some measurements I made

General Mach Discussion / Mach3 and spindle speed controller

« on: July 31, 2008, 06:43:43 PM »

Hi, I have  this DC speed controller that I would like to use to control the spindle RPM on my router

http://www.surpluscenter.com/item.asp?UID=2008073117382038&item=11-2449&catname=electric

Normally, you would connect a 5K pot to control RPM but can Mach 3 can be use with this board

Thanks for your help, Jeff

General Mach Discussion / How to probe and associate it to G54, G55 and so on

« on: July 30, 2008, 09:41:30 AM »

Hi, I have multiple parts which they have their own coordinate. (4 parts on the table), first one is G54, second is G55, etc.

When I probe, how can I associate the first part to G54, the second to G55 and so on.

Do I have to program a macro for G54, one for G55

When I probe, I would like Mach3 to take the GetVar(*********X) and associate it to G54 for X-Y-Z and same thing for the others parts, except, they have to be associate to G55, G56, G57

This the kind of macro I use,  something like it
   
If GetOemLed (825) <> 0 Then       Code "(Probe plate is grounded, check connection and try again)" 'this goes in the status bar if applicable
Else
   Code "G4 P1"         
   CurrentFeed = GetOemDRO(818)   
   Code "F4"
   XNew = GetDro(0) + 1 
   Code "G31 X" &XNew
   While IsMoving()      '
   Wend
   XNew = GetVar(2000)      '
   Code "G0 X" &XNew
   While IsMoving ()
   Wend
   Code "F" &CurrentFeed       
End If


Thanks for any help, Jeff

General Mach Discussion / Tool height input and probe input together

« on: July 23, 2008, 10:59:44 AM »

Hi, just finish my (X-Y-Z) probe and tool height offset probe to measure tools. I have setup pin input for the probe which work fine but how do I hook up the tool measuring device. I've seen in this forum that  they are both connected to probe input.

I did not want to use a plate to measure tool height, I wanted to have a fixed place on my router where I could measure the tool height.

Can I set up another input pin for  (except probe input) the tool probe
 
   (X-Y Probe)

   (tool probe)

I would like to input G code to place the tool over the tool height probe, measure it and be ready to machine my stock.

With my X-Y probe, I can probe on Z axe too, So I could do all my measurements at once.
