General Mach Discussion / Re: SIGNALS REALLY MIXED UP??? Please help
« on: August 30, 2011, 01:02:27 AM »
  ;D ;D   Problem solved...... Turns out that there was not one but 3 bad connections plugged into the back of my G540.  Rewired new db9 plugs and all my problems went away.  I guess it pays to check and double check when problems accrued.  Thanks for all your help, it kept me looking, not to say the amount of knowledge I got from this whole situation.   Thanks again.  Dennis

Let me try to reexplain and tell what's happening now.


Three weeks ago everything with my cnc router was working perfect. In fact for the last 6 months it's run like a clock. Then all of a sudden things went south. Let me try to explain. All the axes XYZ run erratic. Using the jog mood in a positive move, sometimes it will run that direction and then it will run in a negative direction. In MDI when you program a direction it does the same thing, you never know which direction it's going to go??? I've sent back my G540 to the factory (twice) thinking it was a faulty board and it's been returned checked out 100% with no apparent problems. I'm running Mach3, so I dumped the program totally, reloaded it and the drivers, No Change? I changed my parallel cord, No change. I  tried  another computer, No Change, I've changed motors and rewired, No change. My pulse speed is and has been at 15, and I did enable Sherline mode with no change.   Through this whole thing I found out that when for instance I'm running X + and I put pressure on the carriage, it will start to move back in the X - direction??? I am not a technical person, Beyond pressing the "go button" I really don't have a great understanding of electronics. So if you think you can help, please make it simple. Dennis

??? ??? ??? Like so many others I'm a real novice with CNC.  I've built a 3 axes router (David Steel's plans).  Started off with some pretty cheap Chinese electronic and after fighting with them for a few months I purchased a G540 Geckodrive.  Well it's been working great for a number of months and then all of a sudden it was like something took over my Mach 3??  What's driving me nuts is the fact that mainly with the Z and Y drive. X drive works just great.   The signal sent to the stepper motors ( Z & Y) is very erratic.  Whether I'm in Jog or running in MDI when you have it go ( + pos) sometimes it will do that and others it goes (- neg).  The next time it will work great and then once again it's like it gets struck in any one direction - or + what ever way it wants to go???  In fact if you use the mouse in jog mode, pressing the button on the mouse will change directions?? The same with MDI. You call out one direction and it a lot of time will go just the opposite. The the next time it work just fine?? 

I've changed motors, I sent the Geckodrive back and had it check out.  It came back "A"OK.  I can't help but think it's nothing more than set up?  What I need to know is what controls the direction of the motors.  Possibly I've got something switched wrong.???? I use the CNC router for 100% volunteer work in the community and being the fact that it's not working is a real bummer.  Frustrated and really confused. Dennis

Larry, I tried using the extra drive output, seems that even though I felt it worked better, it still played stalled on arcs.  I really think that this Toshiba board isn't doing the job???  I'm seriously thinking of purchasing a Geckodrive 540 to replace it with.

Each one has it's own capacitor, my power supply is a HS 300-4  24 volt 12.5 amps.  Not quite sure what the voltage at each motor is suppose to be (4 wire stepper motors)?    In playing around a lot more, I've found out that the machine seems to run X Y combination moves without hesitation, but when you run arcs, is when it appears that the Y Stalls???? Frustrated, but retired and have lots of time.  I have no doubt that it's electronics and not mechanical.

I've done that, in fact when I power jog the Y axis it works really good, it's only noticeable when I run a X Y combined move?   The Y axis stops and the X continues and then the Y starts moving again, and that happens anyplace on the table, so I doubt that it's mechanical.

Ok, I'm using (3) KL23H2100-30-4B   382 oz-in Stepper motors, TB6560 Driver Board (4 axis) but only use 3.  Ball and screws acme drive.  And of coarse Mach3

 ???   First of all I'm a real beginner in building a CNC.  I built a Router, which was a real blast.  Problem being that I think I purchased a real inexpensive break out board.  Toshiba  board.
I'm having a fit trying to figure out the problem with my Y axis. The other 2 axis cooperate rather well.   At any motor setting or speed, the Y wants to stall out for only a millisecond now and then?  Which pretty much messes up my projects.  I've checked all the wiring, changed stepper motors, and no change.  I've even switched axis.  And in doing so my problem is with the axis that I've changed to. So to me this pretty much tells me the problem is with the board???  In looking into purchasing a new board, I'm really confused as to what to look at or look for?  I don't mind spending money on a quality product, on the other hand I don't want to break the bank (I'm retired) and this is suppose to be a hobby.  Anyway, any suggestions on a new board or possibly might be the problem if not the board.  I would be really appreciate input. Please keep it simple.

 ;DHello, My Name is Dennis .  Retired carpenter and machinist.  Living at Ocean Shores, WA. Live in a community of a spit of sand 2 miles wide by 5 miles long.  Worse fear is Tsunami, but what a way to go!  Lake in my back yard Ocean 1 mile away and inland harbor 1 mile the other direction. 
 Built a CNC Router for a hobby. Doing volunteer community work for various organizations here, cabinetry and sign making.  Keeps me busy.  While working for The Boeing Company I was a CNC operator / programmer.  That end is of the CNC is pretty simple. Then again that was close to 20 years ago.  Programing today seems to be a bit easier.   I'm finding that understanding how the CNC really works is a bit involved and complicated.  A total different world.
