General Mach Discussion / Re: What would cause my limit switches to trip?
« on: November 17, 2012, 10:59:12 PM »
Thanks for that reply fastest1;
I infact do have all the ground wires going to one point (bolt) including the shields from all my limit switches. The negative (-) of my power supply does not go to this ground, because I thought this may cause problems. I checked the "debounce" setting on Mach3, and both are set to "0" . I am a member of CNC zone, but the info you gave me here seems to address a lot of my issues. I will try some of the tips you gave me this week with the help from a friend. I will get him to trigger the TIG welder as I make changes to my mill, and hopefully this will get rid of faults when the machine runs during a program.
Thanks for your help !! It is greatly appreciated.
Dan

The only ground I have is the ground from the input power plug. Not sure what you mean about "star" ground. The negative of my power supply does not go to the chassis ground, unless it's done inside the power supply.
I've never heard of debounce, so I will look into that

General Mach Discussion / What would cause my limit switches to trip?

A bit about my machine;
It's a converted Hurco KMB1 that I did a few years ago but rarely use it, so I'm still finding the odd bug.
My limit switches are 24v proximity switches, so there are no moving parts. Since I built this machine, everytime I would TIG weld near it, the machine would shut down and display a "limit switch trigger" fault. So I don't TIG wels anymore when the machine is running. The machine used to trip also when relays would activate, but I fixed that problem by putting capacitors across the pull down coils.
In the past couple of days, the "limit switch trigger" fault shut my machine down 3 or 4 times right in the middle of a program for no absolute reason !! I had a 1/16 cutter carving wood, so there was no load on the machine. I tried to watch the Diagnostics screen to see if I could see a light flicker if it happened again, but of course it ran great afterwards.
Any ideas? Has anyone experience similar problems?
Thank-you, Dan

I copied the .TAP file (g-code) and pasted it on my desktop. I opened the file through Mach3, and loaded it from the desktop. I was able to edit it. Thanks guys !! I feel stupid !! I guess I couldn't edit the file, because it ( I assume ) is actually on the computer in my house.

Dan,
Are your gcode files somehow being marked "Read Only"?

Possibly !! I'm not a computer whiz, but do have basic know how. How could I check that? it almost seems like that seems to be the problem

Nope !! It still wont let me. tell me if this makes any sense !!
I do my drawings in my house on the home computer. I then save the g-code on a file I share with the computer on my milling machine which is connected by a lan wire in my garage. Is it possible that it wont let me because i'm not on the computer that originally created the G-code?

It's a windows error saying "make sure the path and file name are correct" !! I printed the screen, but don't know how to post it on here.

General Mach Discussion / I'm unable to edit my G-codes from Mach3
« on: November 16, 2012, 10:36:21 AM »
While running my program, I dicvered an error in my G-code (M04 instead of an M03) I clicked on the "edit g-code" icon, and my g-code opened up in MS word (I think) After changing the bad command, I clicked on "save", but an error window pooped up disallowing me. In the past I've been able to do edits, but for some reason I can't anymore. Any help would be greatly appreciated. Thank-you, Dan

I checked the specs on my motors, and they are 620 oz/in NOT 960 !! :)

rrc1962 - a peace offering  ;D


No biggie.  I'm kind of in the "build the machine to suit the need" camp rather than the "build the machine and then figure out how to make it work" camp.  We pretty much agree.  The best solution is acceleration...which is a bit confusing.  With 960oz/in motors and a 50 pound gantry, his machine should be able to run some very high acceleration numbers.  Up until this post, I hadn't noticed where he posted his accel numbers.
My very first post stated that I had increased my acceleration rate to 40.
