BR549, you are right. There are a couple that will work perfectly in the Grainger catalogue. For the benefit of others that may have the same problem I am going to use a Dayton #2A561. Thanks for your help.

Hey BR549, The delay relay is a great idea and i did some exploring online. I did not see anything in the $20 or $30 range. Do you know of one? I can relay the power supply itself with the 120 vac input or relay the 24 vdc output. The brake pulls less then 1 amp.

General Mach Discussion / Z axis brake releases to quickly on reset.
« on: September 09, 2011, 09:33:12 AM »
Hey guys
I know someone has a simple solution for this problem. I have configured my controller in a very typical way. When the system is reset, on the screen, power is put to my amplifiers and at the same time power is put to my electro-magnetic brake on the z-axis to dissengage the brake. I have a heavy spindle thus the brake requirement when powered off. The problem is that the brake is dissengaging before the z-axis servo takes over holding the spindle up. How can I slow down the power to the brake by about 2 or 3 seconds to get some overlap? Can i use a thermister or a capacitor? Delay relay? I am putting power to the brake by switching on an 24vdc power supply that is only used for this brake. How are you guys solving this problem.
As always....thanks for any input.
Russ.

Hey hood
Being a VB, button how can I address the"set tool offset" button from the auto-z macro that I am working on? It would simplify this macro if I can do a " DoOemButton (*********)" or something like that for the "set tool offset" button.

Hey guys thanks for the help.
Do you know what the Oem Button code is for the "set tool offset" button? That should put the value into that offset DRO feild and the tool table as you do. Do you know if I need to toggle the "tool offset" led before the "set tool offset?

Hey Hood
What is DoOemButton (121) from you script?

General Mach Discussion / Auto Z for an ATC

Hey all.
How do I get my Auto-Z value input into the tool "Z 0ffset" DRO field complete with the touch plate thickness added?
As it is now, it enters into the Work Z offset field and does not adjust for the plate thickness. I am using an ATC and I want to key the tool number, Change the tool manually and then run the Auto-Z and have it enter for that tool.
This is what i am starting with:

PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO
If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P5" ' this delay gives me time to get from computer to hold probe in place
Code "G31Z-1. F10" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness
Code "G4 P0.25" 'Pause for Dro to update.
Code "G0 Z1." 'put the Z retract height you want here
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
Exit Sub
End If


Thanks for your help. Russ.

Hey Hood,
Thanks for picking upo the ball. I have done the optimization. It did not help. I have never run the driver test. What is it? where is it? what does a good driver test look like?
Thanks again for your help hood.
