Hi, Adam

Your use of pin 11 for all axises in incorrect, Should be Ground.

Pin 10, X--, X++, X home in series other end to Ground.

Pin 12, Y--, Y++, Y home in series other end to Ground.

Pin 13, Z--, Z++, Z home in series other end to Ground.

Hope this Helps, Chip

Chip - do you really mean my connections are wrong?  Its working fine.

All my Limit switches are on the end of each axis, in series and go to pin 11 and ground.

Maybe it works both ways, yours is just easyer and uses 3 pins - I use 4 pins.

General Mach Discussion / Re: Feed Rate

Thanks

I changed the F60 to F120 and the milling time was 4 min in stead of 7 - it works, but how fast can I go?  I mill in blue foam for now so I wish I could do it faster.

My Motor tuning is: Acc 100 and Velocity 500, but it can go faster.

Does it mean that I can use the F value up to 500?

Chip - I did try to change the FeedRate on the program run page, but it will not change.

General Mach Discussion / Feed Rate

« on: March 04, 2008, 01:23:05 PM »

Hello

I`m not exactly sure what I`m doing, but I did mill today for the first time

If my blue foam was more level I could mill the rest of the letter.

But it took over 7 min to mill.  How can I change the Feed Rate? The on screen Feed Rate is 60 and 100% and it wont change. It always resets to the old value.
When I use the Shift+arrows it moves much faster.

In Mach3 the "input signals" can be hooked up to pins 10,11,12,13 and15.  You should use the same pins on your BOB.

Hello again

My Machine looks like on my drawing.

All the Limit switches uses the same Pin (11) because they are in series.

I hope it helps

How about telling the software in the " input signal" , which Pin on your driver board you use for the limit switches in series

X++, Y++ and Z-- should use the same PIN number.   - if your Z axis limit is negativ.   I have to check that - i`ll be back.

Thanks

Maybe a stupid question, but is there a video showing the machine ( not a Mach3 screen) starting a job from the begining?

Hello PJ
I don`t know how much experience do you have, but this is my first time and it took me one week to understand the setup and set up my machine:-) I still have a lot of questions.
There is a great instructions and videos on the webpage.
