General Mach Discussion / Re: limit swtich not hooked up but still getting triggered anyways

Thank you for the help. I got the limit switches turned off and the motion controls are working again. I will start working into the problem as you have suggested.

Thank you, I did not think of that, I will give it a try.


If it works where should I begin looking for the problem?

This machine has ran so well the past few years that I have forgotten how to trouble shoot it

I had a problem similar to this before I had non shielded wire on the limit switches. If I remember correctly I changed the debounce and the problem went away.

Not the case this time. the limit switch activated a couple times when running code and then it totally stopped. I can't get the limit switch error to reset at all. router turned off reset computer everything.

This has been a very healthy machine for the past two years with few problems. The motion controls came from build your own cnc. is there a chance my b.o.b. is toasted?

I need to adjust what I said. "Automated setup of inputs works when I jump a wire across the breakout board but not at the homing or e-stop switch."

General Mach Discussion / mach 3 homing/ E-stop switch woes.

« on: October 17, 2012, 04:06:11 PM »

Hi there


I have just recently rebuilt a machine for a friend. It is moving on all the axis and I can get mach 3 to auto set the homing and limit switches when I jump a wire across the break out board. but when I go to test the homing and e-stop at the switches I am not getting any reaction.

I have checked the wiring to make sure I was getting a good signal and there is very little resistance in all the wires. The "bob" and the parallel ports seem to be working fine.  I have also checked the ports and pins in mach 3 and they register as what I assigned with the automated setup of inputs function.

I should add the I tried a debounce of 2000 with no luck. I might need more or less but not sure.


Thanks for reading

Alonzo

cancel that. I discovered that a probotix board will ont function if one of the drivers is shot. I unglugged the x axis on the bob and the stepper motor came to life.

Hi there

I am hooking up mach 3 to a probotix pbx-2 3 axis kit. I have set the ports and pins to probotix's specs, I have made sure the parallel port address is correct. I have checked to make sure the max nc is not turned on. I did the driver test and it is good to excellent.

The only thing I can think of is re install windows xp and mach 3.

Do any of you have any other suggestions?

Thank you,  Alonzo

General Mach Discussion / Re: need help hooking up spindle

yep the only wires I need to hook up is the three that I have my finger on. the only information I can find on the board is it is a puma board. I havn't had much luck finding any more information on it.

I would spring for the new motor board but I am afraid that it will not work. the board that cnc4pc uses 10 volts total, while the motor on the cnc machine is  rated for 110v dc.  The board reccomended to me from probotix tech is here, " http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=58 ".

I have been on the phone with probotix several times today. The man could not tell me how to hook up these wires. He reffered me to cnc zone to buy a new motor board the gentleman at cnczone told me that the probotix board was a  bad choice and said I should buy one of his. I would but I have already got the new breakout board sitting here.

Before I go and buy another motor board or breakout board I am going to start randomly hooking up wires. . . Then when I see smoke bellowing from the machine I can justify buying more parts.

I was looking in the mach 3 pdf user doc and found under the head 5.5.5.3  where it discusses the step and direction spindle control. do I hook up the min and max into the step ports and the ref input into the direction port?
