ger21 I use your 2010 screenset, by the way I love it works great. These CV setting you mention are they set in the general config section or in the settings section of your screenset, or both? I ask because I get rounded or cut off corners on square corners, especially on text. Thank you

There is no toolpath that reliably exhibits the problem. thats the whole problem. sometimes i can run 2 or 3 large toolpaths and have no problems. other times it may happen only once during a toolpath run or several times. when i rerun the toolpath that had the problem it wont have the problem. i know you are trying to help me and I appreciate it and i can understand your dilemma by not being able to see the problem.

reducing my microsteps on the driver to say 1/8 which is half reduces the detail in my engraving / V carve .    How do you turn off the toolpath display?

i have not change the motors or power supply.     when i jog the motors using the keyboard they run great.    
 
i have gone over all my bearings nothing binding there, inspected each link in the chains no bent or mis -shaped ones, checked every inch of my rails for bends, bumps or waves nothing there either. re checked all my plugs and connections all good.

i have even ohm tested each wire in the harness between the plugs all are good.

when my machine is turned off i have pushed the gantry the full length of my table both with the chain connected and without, it is easier to move without the chain connected to the motor, but suspect thats normal.

Not wanting to spend $500.00 to a $1,000.00 buying new electronic chasing phantom problem, i think i will continue to monitor my system and see if this problem worsens or developes a pattern.

Are you saying that this could not be a Mach3 software problem, that it has to be my electronics?

Again thanks for your help.
Jeff

Well - maybe so but why would motors that seem fine on a "small" machine lead you to think they'd be just as good on a different machine?

The place I got my machine from and about 2 dozen people that own the same machine and package, say that the electronics package I have works fine with their bigger machines.

You had mentioned you need more info about my machine, this is what I have and where I bought it..

If you have any recommendations for what I can save from my electronics and what I need to change to that would be great.

I want to thank you for your help/info with this problem.

the setup on the driver is set to 1/16.    Sometimes the stalling is during a no load travel to my touch off fixed plate, this can be just as it starts to take off or after a few inches of travel or after 3 ft of travel. Sometimes it's during cutting and  the samething as the no load times.      There is no pattern to the stalling. In fact sometimes i can cut two or three things without a stall.      Also I dont take much of a bite when cutting sometimes 1/16 , 1/8 or 1/4 depth of cut depending on the size of my endmill/ V bit but nothing more than 1/4 even on a 1/2 inch endmill.        I find i get a better cut taking less of a cut.          
 I guess this is a dumb question but if the motors are a bad match for the drivers and the PS is less than half of whats needed why would Keling Inc package them as as ready to go kit. What Drivers would be good for the motors I have? And I'm sure I can find an 84v PS. Although this package worked OK on my small 2" x 4' machine for 2 yrs. No stalling of any kind.

Yes sir thats my kit.    My machine uses chain not Acme thread to drive the X and Y.
Settings are:
X Axis
Steps per 912.4659217
Velocity 250
Accel 5

Y axis
Steps per 1420.292255
Velocity 250
Accel 5

Thanks Stirling
I guess its back to the old drawing board as they say. Not quite sure what to chack for losing steps especially on just one axis. It cant be from heat, each motor has a heat sink on it and the X axis also has a 12v fan blowing directly on it since it is enclosed in the gantry. I also have three 12v fans blowing onto each of my 3 drivers, they barely get hot.  I have 2 fans mounted on the box 1 blowing in the other sucking out, both with filers to keep the dust out. I have changed my BOB, checked and tightened all my electricial connections, checked all my settings within Mach3 they are still what was set from the begining.  In fact when I built my electronic box I soldered all my wire ends before connecting them. What else can I check? If my BOB was bad how could I tell? If the driver is bad, again how do you tell? I really dont want to buy a whole electronic package.

Back to the original question my machine was running ok for awhile then it started to lose steps in the X axis. my settings for the step pulse and direction are both 0. should i change them? if i do change them do i do it step pulse 1 and dir 0. or do you raise them equal? hope this sounds right. i have been searching the forum looking for answers. this string is the first one to actually answer what they are.

not sure if I fixed the ground problem or if there was even a ground problem. i removed my shielded wires for the probe and plate, replaced them wire just regular old 18 gauge wire and installed a .01uF capacitor from 5v to Pin 13 and tested it. well to my surprize the touch off works great again. Hey Gerry thanks for helping me.
