General Mach Discussion / Re: First Post - need some set-up guidance

Hood,

I have shielded cables for my limit/ home switches but I did not have them grounded.  After your recommendation I grounded to the chassis of the enclosure that I have the Geckos in, but unfortunately I still have the problem....

Debounce is set to 10000 and I still have the issue...

Funny thing is, every 30 seconds or so, while watching the diagnostics page, I see the M3 home switch activate briefly, then all of the limits get thrown and I get an E-Stop.

Additionally, I see the number 4 pin continuously lit... even without Jogging -  #4 is the step for the y, so not sure why that would be happenning...

Wow!

Thanks for all of the feedback!

Very much appreciated....

looks like I had two challenges... Almost hate to admit it....


1) As Brett suggested, I looked to see if Jog was on and in fact it had been turned off...

and 2)  One of the wires to one of my motors had become disconnected due to a poor solder joint.

Great Idea to disable the limit switches...

Everything seems to be working ok now except the Estop tends to get triggered too often......


Thanks again.

General Mach Discussion / First Post - need some set-up guidance

Hi folks, this is my first Post. 

I'm hoping to get some guidance...  based on everything I've read here over the last few months, and the huge experience pool that clearly exists in this forum, I'm very confident that the answer will be obvious to most of you and perhaps be able to quickly point out what I've done wrong... 

Well,  I just recently finished building my machine, and started setting it up.... Everything seemed to be working, but then the motors stopped responding. I was trying to tune them at the time and must have dome something wrong.

My machine has one bipolar motor, and two 8 wire unipolar motors wired in bipolar parallel.

Drives = 3 Gecko 201's

All of my limit switches are all normally closed with an external 5 volt supply to pull high on pin 13.

EStop is wired similarly to pin 10.

Ground is pin 19
Ground Limit Pin 18
Z = Step Pin 7
Z = Dir Pin 6
Y = Step Pin 5
Y = Dir Pin 4
X = Step Pin 3
X Dir Pin 2

I have attached a word doc with a few screen shots...  Didn't know how to include the XML file ( or if I was looking in the right place)...


Thinking that someone else will see it right away....

Thanks in advance for your help.

Pete
