Thanks Steve,

 As many times I have been in my box setting it up, cleaning, exc. I have not had that happen. The steel pins that you push the connector for the motors could be say about 1mm longer. If they are not seated in 100% you get a bad connection. Just a thought.

 Again Thanks for the fast reply and spot on information.

PS: any thoughts on why I have to start a program before I can start my spindle?

General Discussion / X only moves to -.

« on: September 24, 2015, 03:09:01 PM »

 I have had it running OK now for about 3 months and to day it wants to through a fit.

 I have the VFD switching on J19 (put it on today) had to change Enable2 (pin 1) to RED on Active Low.

 I loaded a program to cut, set the x,y,z, to zero and hit start. The program was ET with piece sign. I am using Aspire 8 for the text file and the order of cutting is eyes then complete cut out. It started with something ??? not what Mach3 was showing for the cut job.

 It ran into one of my X limit switchs and triggered an Estop. (that is working well thank the stars) I went to (settings) in Mach3 hit Auto LinitOverRide to get off the switch. ALL it wants to do is go towards the switch (X-), (hit Tab) press X+ it goes X-. go to MDI type in X10 (mm) Mach3 X readout goes to X+10. But the machine goes -10. Type in X-10 the machine goes 20 to minus.

 I turn off everything, moved the X by hand back the the middle of the table and restarted all, computer, pmxd, vfd. It still only moves to the minus.

 I just put Enable 2 back to green, restarted, still the same.

 Y and Z are OK.

 This may not be part of it, but sometime back we lost power in the area while I was running the table. Now when I wake up the machine and hit Spindle CW F5 the spindle control card relay clicks but the spindle will not start. If I load a program, hit Cycle Start the spindle starts. After that I can start and stop the spindle with or without a program loaded.

Sorry about the 106, Yes 126.

 I do not know what is going on with the links in and out of this forum. I try to send you a reply and it does not show. Then when I get a notice in my Email that someone has a reply I end up at a string from back in January. So I started a new string to get a message to you.

This is not the mesage I was even sending. This is was an old message.


 Yes this is the same problem with the Estop. In the drawing I posted (all power 24vdc) comes from the 24vdc trans and all 230vac is after the main in the control box. (If this helps)

 I have posted answers to your question Bob, but they are showing up on the forum. What am I doing wrong?

Sorry from being late on the reply. Thought I had set it a long time back, but do not see it.

 The problem is this the same.

 I did not show that the two relays going to the Estop are in ser. Plus my E switches have two N/C switches on them.

 Hope this helps.

Hi Steve,

 Thanks for the reply.  The relays that I use are standard DPDT 250v 10a. They are what I am using to jump from gnd to Fault and Estop.

 When I power it up for the first time I flip on the main breaker. This power the 126 card, 24vdc supply and the cooling system. The Estop is set because I have not set my emergency buttons.

 Once all are in the open setting the 134, Gicko's and the relay wired to the Fault get power. The button (to repay) in the box by my spindle is the only thing hooked up to Estop on 126. Now the Estop light goes out and all is good to go.

 Now if at sometime later if I push one of the E buttons the system stops and goes into Estop. This is right. But is I reset the buttons the 126 Estop will not reset until I either turn off power to 126 or close Mach3.

regards
Bruce

General Discussion / LED Signs

« on: June 24, 2015, 02:29:57 PM »

 I found this out the other day.

 If you are cutting plastic to make LED signs coat it with a heavy coating of Simple Green. I have been playing with speeds til I am blue and it would keep gumming up my cutter. I was doing some cleaning around and got a wild idea so I sprayed to plate. Dam it works.

It was a unit I was in.

General Discussion / Mach3 holding E Stop

« on: June 24, 2015, 02:22:12 PM »

 First I want to thank everyone for the help I have received to get this first time cnc user going.

 Back ground: Toys

computer with single parallel cable.
126, 107, 134

Software: Vcarve8, Mach3.

 I have a relay hooked up to the power to the 134 so if it drops power the relay closes on 126 fault. I have three safety kill switches. One side to 106 E Stop, the other side kills power to 134 and the spindle.

 The trouble I am having is on the first time wake up (if Mach3 is on or not) all starts up and ready to go.

BUT.   If I am running and do a safety switch E Spot it goes into E Stop like designed. But will not come out of E Stop until I turn off all power the the 106 or turn off the Mach3 program then restart.

Is there a setting I need to change?

Regards
Gizmo

The red light is still on Bob...   Next....

 Yesterday I wired up a relay that would close on the fault of 126 if the 134 card lost power and put the other relay back to the Estop like I had it before. The dam thing worked ??? The Estop red light would go on  off with either of the switchs pushed. (Estop or fault) It worked all day. Then last night when I tested it the red light would stay on. So I turned off the power to the 126, waited 30 sec. turned the power back on to the 126 and it started working again.

 Could it have something to do with the power we have over here? 130,130, ground. There is only one other country in the world that has the same setup. One of the east blockers.

The button I use for the Estop was a NO so I hooked it to a relay. The relay NC set is hooked to the 126 Estop. If I push the button the relay fires the switch to the Estop opens and the system goes to Estop. I let up on the the button the relay switch closes, but the RED light stays on.

I played some more with the motor settings and it has stopped the jumping. Hopefully that one is fixed.

Now I am working on speed cantrol to get better cuts and bit live. This is some different the running my 75- J2 Bridgeport.

Ben having fun. grin

 I have two thinks I am trying to figure out with it.

1. I wired up a button in a box by the spindle that goes to the Estop on the 126 card. If I push it the card does the Estop as designed. BUT. If I push the Estop reset button on Mach3 the 126 will not exit Estop (the red light is on (126)) so I have to turn power offon to the 126 to reset. What am I doing wrong?

2. The stepper motor that is on my X axis now, it was my Y axis. I turned my table direction. From time to time ( it looks to be ramdumb ) make a jump in speed. Most of the time the it is OK but from time to time it locks up the screw making noice. This puts the machine out ot (now) X axis ''0''.  ???  Bad motor?

 I do thank you Coils and Steve for all your help.

 It is working, I have set it on a test run to level the table (MDF). What bits are good for use on MDF?

 The box I am not 100% complete on but close. I got the idea from a video I watched about using plex on the sides to keep the cable grounds away from the box body.

 Now all I have is playing/testing the motor amps and speeds.
