Yes, I have had a problem with the blue caps before, which is why I have a spare drive now. Thanks for the suggestion, I will investigate that.

Thanks for reply
I am not sure I understand, the gecko on the 'pop' x axis still worked (or at least lit up) when put on the non faulty y axis wiring, it was putting the presumably faulty x axis wiring on the y axis gecko that caused the second pop.
However, it has got to be right that  should check all the wiring, and I will, although looking at one of my x axis rails, clogged with sawdust, could the machine stalling the motor cause this?
Is one way to go get some readings off the wiring into the Gecko that still works and compare with the other two sets of connections that now don't?

General Mach Discussion / one pop then another, no Gecko light

« on: September 05, 2013, 05:47:54 PM »

Hi guys, snazzy website now...
Not exactly Mach 3 related, as I have had many years of trouble free use, but you guys have helped me before, so here goes:
Jogging along the x axis, unusually some stuttering, then a 'POP' from the region of the electronics, and no x axis movement.
So i have a look. No light on one Gecko 201. Ah, must be the Gecko? Put a spare Gecko on the connections, still no light. Check the spare Gecko on the same connections as the lit Gecko on Y axis. Lights up. Must be the connections therefore to the x axis Gecko. Put the X Axis connections on the Y axis Gecko  'POP' and no light on the Y axis Gecko either now, although I don't suspect the Gecko's, as they worked on different connections after the POP.
Is this enough info for you guys to tell me what I need at least two new ones of?

Given a down arrow, or an up arrow, the spindle randomly ticks from side to side, tries to go one way, buzzes, tries to go the other, buzzes, tries every 1 or 2 seconds: Bbbrrr Brrrr Brrr Bbbrrrr.
Dro is correct of course.
However. I have now tried swapping the Gecko's, to eliminate them at least, or see if the problem followed the Gecko, and it didn't . The problem seems to have gone.
Any ideas what happened?

General Mach Discussion / Random twitches after crash

« on: October 28, 2012, 10:24:09 AM »

Hi All.
After a dive into the bed, the z axis twiches randomly. (the stepper is out of the machine, so it isn't something slipping).
Is a short dive enough to ruin my stepper, or is there some other error or setting I should be looking for now.
I believe the crash was caused by my asking it to go faster than it normally does. (300%. It isn't recommended I know).
Look forward to any replies.
Jim

Well.
I looked in the plug and it wasn't that, it was the next wire i looked at. I can't believe it. Spade connector off my copper donut.
How do you guys do it? It's some kind of voodoo isn't it guys? 34 reads, you each send out some kind of vibe...there's the problem solved This forum is the greatest. here's  some back~~~~~~ Jim

General Mach Discussion / Can't get started again.

« on: March 10, 2010, 07:42:35 AM »

Hello Guys.
I have moved premises, and it involved taking the machine to pieces.
I have missed something out in the reassembly, because I can't get the machine to 'energize'. Normally as Mach3 starts up there is a click from all the steppers, and we have power. I am not getting that, or any lights on the Geckos, although there are one or two on the circuit board. Mach3 and PC seem fine, just not the machine.
What should I look for?

Hi guys. I had this.
Hi all.
 After quite a while of trouble free motoring, today I have random z movement, from the keyboard, and from the Tab controls. (press down get down, press down get down, press down get up


I can't see if you  have tried jogging from the tab menu. If you get the same problem here, and you have Geckos, it is a bad connection in the blue plugs and pins. remake these, or just tighten the loose one. This has cured it for me.
