General Mach Discussion / Re: Motors are not operating correctly
« on: August 04, 2016, 02:26:37 PM »
The psu came installed in a prewired control box.  I priced the individual components that were recommended on various forums, and it was roughly the same to wire myself in-comparison to a prewired control box.  Also, I lack the electronic expertise to tackle such a project.  The following link outlines the components in my setup.   http://www.automationtechnologiesinc.com/products-page/g0704-kit/3-axis-cnc-stepper-control-box  I am questioning the overall quality of the psu, since it has lasted only two years with minimal usage.

It indicated low voltage with no load, so I will replace the power supply.  The power supply is approximately 2 years old with not a lot of hours of usage, and cost around $110.  Would you suggest to go that route again, or an alternative setup?  Also, what is the likelihood that a power supply issue would be the cause of the direction problems that I outlined in prior posts?  Thanks for all of the help.

"Disconnect the supply to each of the driver's pul+ one at a time and see if the BoB voltage rises to +5 volts."  

I did this and there was no change in the volts for the 3 drivers.  I put the multimeter on the power supply 5V connection to see what it is showing and again checked the 5V connection on the BOB.  They both showed 1.15.  The following is the model of my power supply, but cosmetically mine looks different than what is pictured.  http://www.automationtechnologiesinc.com/products-page/switching-power-supply/48v12-5a   I also checked the 12V connection on the power supply that is connected to the case fan and it showed around 12V.  There are 2 wires coming from the 5V of the power supply consisting of one to the 5V on the BOB and the other connected to one of the driver's PUL+.  Do I have to replace this type of power supply entirely, or just disconnect the 5V wires and add another 5V power supply?  Something like  http://www.automationtechnologiesinc.com/products-page/switching-power-supply/kl-10-5-5v2a  Thanks.

I used a multimeter to check directional pins on BOB.  Also, checked 5V on the BOB and it indicated 2.82

Operating correctly:
(Z) 2.84, .56
(Y) 2.82, .88
(X) 2.62, .92

Here is what I got when  Z+ worked, Z- no movement, Y+ and Y- moved toward Y- direction regardless of what key associated with Y axis was pressed, X- and X + moved to X- regardless of what key associated with X axis was pressed.
(Z)  2.63, .88
(Y) 2.63, .92
(X) 2.32, .92

When it isn't working correctly the malfunction is always the same as indicated above which may mean something.  What is your take on the numbers?  What else to check?

I turned off the wifi for the internet, replaced the wireless keyboard/mouse with wired versions, and checked the motor cables.  I jogged in all directions approximately 20 times and it ran correctly, so thought it was fixed.  However, ran it a few times and it started having directional problems once again.  Then it worked correctly again.  Essentially, have a unreliable/unusable mill at this point.  Any other suggestions?  Could uninstall and reinstall of Mach 3 possibly help?

Yes, that is exactly what happens intermittently.  It will move in the correct direction via the keyboard arrows, then not, and okay again.  However, this also happens intermittently when using the jog arrows on Mach 3.  The intermittent nature is the problem here.  It would be alot easier to determine the problem area and course of action if it happened all the time as opposed to the 5th, 20th, etc. time.  The motors and drivers are not getting hot.  Any other suggestions?  I certainly appreciate the help.

The control box was purchased/made specifically for enclosing CNC components and has a CPU fan.  I have been utilizing a wireless keyboard and mouse for approximately six months without any apparent problems.   Also, have a wireless internet connection on the computer for updates of CNC based software.  Can any of these potentially cause interference with drivers, etc. resulting in something like intermittent directional issues?  Thanks.

Stephen, The mill has been untouched since yesterday evening.  Before I attempted anything, I jogged each axis to see what would happen.  Everything worked in the positive and negative directions for each axis with the keyboard and via Mach for approximately fifteen times in each direction.  Then I jogged again and the following were the results: Z+ worked, Z- no movement, Y+ and Y- moved toward Y- direction regardless of what key associated with Y axis was pressed, X- and X + moved to X- regardless of what key associated with X axis was pressed.  Then I waited about ten minutes and it worked again in all directions for approximately ten times each.  No further attempts to try anything.  What do you make of the aforementioned?  Any other suggestions to check?  Thanks.

Drivers, BOB, and power supply are in a control box and wiring for motors are contained within motor covers, so isolated from lubricant.  The cleaning didn't involve any chemicals, and the lubricant has been used may times before and was no where near wires/components.  I went the over connections and all seem secure.  This is frustrating to say the least considering everything was working fine.  I am by no means electronic proficient, so excuse me if my questions seem stupid.  Specifically how do I check with a meter direction signal wires between controller and drivers?  What numbers should I be looking for?  Anything else to check?  Thanks.

I embarked on a cleaning/lubrication routine with my G0704 mill over last weekend. However, when I attempted to jog through each axis there were problems with not moving at all and moving in the wrong direction. For example, it should have moved in X- direction, but both arrow keys would result going in the X+. Then the Z would move in the positive direction, but not at all when attmpting to move in the negative. This would happen a few times, work correctly for awhile, and then start acting up again. All the connections seem secure and there has been no changes to hardware or Mach 3 settings. There were no error messages from Mach 3 or UC100. My machine has the following hardware:

UC100 USB motion controller
 (2) KL-5056D drivers
 (1) KL-8070D driver
 (2) KL23H2100-50-4B, NEMA23 570oz/in 5A 3/8” Dual Shaft Stepper Motor
 (1) KL34H295-43-8A, NEMA34 Stepper Motor – 906oz in 6.1A Single Shaft
 48V/12.5A Power Supply, 115V/230V
 KL-DB25 BOB

 Mach 3

 I am not sure if this is a hardware and/or software issue. Would should I start to rule out to trouble shoot this? Thanks.
