General Mach Discussion / Re: Mach3 and spindle speed controller

« on: July 31, 2008, 10:19:56 PM »

Hi, Thanks for the reply, this look like interesting stuff.


DC-03 should work since I do not need the direction option, spindle always spin in the same direction

So this board would replace the 5K pot.
 
Does it need any feedback from the spindle, I have spindle indexer that send signal to Mach3 to see spindle RPM on the screen, could it be use with this board.

Normally, Speed motor controller does need it to increase RPM when load  increase to keep Rpm Steady.

If you tell me that this will work with the Controller I have -  http://www.surpluscenter.com/item.asp?UID=2008073117382038&item=11-2449&catname=electric  , I am a buyer

Thanks, Jeff

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.

Ce n'est pas pour la traduction du manuel mais je suis du Québec moi aussi.

Thanks for your help guys, really appreciated.

Will try to find a better board for my motors.

Hi, my board have a maximum voltage rating of 32 volts.

This is my nema34 motor for the Y axis.   http://www.kelinginc.net/kl34H2120-42-8B.pdf        (1200 ounces)

These are my motors for the Z axis and X axis.   (X axis have 2 motors for the gantry for a total of 3 Nema23)  http://www.kelinginc.net/KL23H286-20-08B.pdf     (425 ounces)

All are connected in series.

I'm just asking since I have 2 similar power supply at 6.5 amp instead of buying one at 12 amp.

Hi, thanks for the reply.

My router table have 4 stepper motor, two nema23 425 ounces of torque for the  X axis, one nema23 425 ounces for the Z axis and one nema34 1200 ounces torque for the Y axis. When they move all at the same time, I think my power supply is not powerful enough since it can deliver only 6.5 amp and all motors together would need more then that.

This is my board. :

This is my power supply.:  S82J-15024A1 ( this mean, 150 watts, 24 volts)

http://pdf1.alldatasheet.co.kr/datasheet-pdf/view/152773/OMRON/S82J-15024.html

I have two of these power supply but only one input on my board for the power. I'm just wondering if I could hook up two power supply in parallel in only one input to have more current deliver to my motor. Sometime when the move all together, one or two loose steps but this never happen when only one or two are moving.

Hi, My power supply for my router table is a switching power supply at 24v 6.5A.  Look like it is not powerful enough for this purpose. I have two, can I connect both in parallel to increase current for the motors without damaging my board or power supply themself. Thanks for any advices, Jeff
