well that looks really good incress to 25000 see what happens, it shows that it`s connected it all looks correct is there something that your bob needs a setting like charge pump

It is a cheap, 3020 router.  This was supposed to be my training ground while I built the X2 mill.

Best I know nothing else is involved, no pumps, switches etc  M3 did not have anything set.

I do get some history when I try jogging occasionally, Darwin out of bounds errors.  So the system thinks its working.

You don't know how much i appreciate the help, most of the time i don't know what to try next.!

bar553,

If my failing memory serves me (it's been a few years since I set up my M3 system), Mach3 provided a charge pump output that one wired to the BOB.  When I go to Mach4, I have to set the charge pump output to the appropriate pin or I get the results you are describing.  May I suggest you check the docs on your breakout board and look for any mention of a charge pump.

Thanks another thing to try............... no documentation, so experimentation here we go.

Just so i understand, set the charge pump (signal1) in Darwin output..............to a pin
Then enable charge pump 1in M4 outputs to that signal in darwin?

I may have to install M3 again to see, i dont recall enabling anything but I have slept since then.

Progress??!!
With Chargepump1 enabled, and pin set to 9, i get "z" movement.  Pin 14 I get some x movement.  Saw a little y earlier, but cant repeat.

I really dont understand it, but it's progress.

it could well be the bob has packed up they are cheap as *********e bobs with the movement was it with just Darwin running or with M4, with how the water fail looks you can push the pulse rate high

I found this link to online documentation for the 3020 router.
www.marcmart.com/download/CNC%203020%20usermanual.doc
I notice the port and pin set data for the motors is different from what you described.  The documentation shows ports and pins that are what I have seen in other instances but that is not to say you are wrong.  Also, set the negate signal boxes as shown in the documentation.

The router does not appear to use a charge pump.  The use of a charge pump on pins 9 or 14 to get movement tells me something else is going on.  I have convinced myself that it is a configuration problem, not hardware (M3 works).

As suggested, don't bother with Mach until you get proper movement in Darwin.  Messing with Mach at this point will only add confusion.

I had the same thoughts, supposedly it should work with the test version, without M4 even on....  I have that manual in semi Chinese.

More playing tonight.

Thanks for the thoughts.

here's a thought..... most stepper drivers have an enable pin on them.... when I built my machine I connected my chargepump to that pin on each stepper driver. so if the computer locks up or is not getting a good pulse it will disable the stepper drivers and theres no motion. if you don't have a chargepump you still have to enable the stepper drivers. theres so many different kinds of boards out there it's tough to say.
