You can change/customize your splash screens too.  Just change the 3 BMPs to whatever you like.

c:\Mach3\Bitmaps\Splash.bmp
c:\Mach3\Bitmaps\Splash1.bmp
c:\Mach3\Bitmaps\Splash2.bmp

I changed mine to the following:

I wish it did too....  My VMC Project could use it.

Here's a pic of the drives and some other items i'll have in the enclosure.

Anyone have any pointers on laying out the electronics in a enclosure to keep it neat and help prevent emf noise?

Looks so neat without the wiring

Cooling fan?

Backlash is a big problem with these kinds of tables.   However, they might be OK depending on what your cutting.

your site is a treasure trove of information and I stop by every once in awhile to see what you're up to -

Agreed !

After you find the specs on the servos, then you can decide what drivers are best. 

Geckos are rated at 80VDC and 20AMPs (1600 WATTS of power).  If you build a power supply big enough and your servos are specs closes to this, it will work fine.  We are using this kind of setup on our BP412 VMC Project:  http://www.machsupport.com/forum/index.php/topic,13365.msg94979.html#msg94979

The acceleration is set to 15 for both the X and Y using the 100CPR/400PPR encoders.  I am still turning the Z so its not final as of yet, still working on interfacing eStop with the drivers as time permits.

The servos are the stock BP412 ones with new encoders.

Have not started on the Spindle Orientation.

Show"N"Tell ( Your Machines) / X and Y Testing

« on: March 12, 2010, 02:18:07 PM »

The 3 Power Supplies are now completed with the X, Y and Z Axis integrated and tuned.  Used some high tech encoder covers to protect them (don’t worry, there is metal protector as well).  The performance has been good on the X and Y, getting rapids as fast as 250 IPM, however the Y axis will faults sometimes.  So we down graded to 200 IPM, and the X and Y run all of the time with no issues.

The Z Axis is working, but I have not connected it to the ball screw yet.  Working on the eStop - Gecko integration first, I do not want the spindle head to slam down if the driver fails.  The Z Axis brake is functional and working with eStop, just want to get some confidence first before going live.

Thanks,
JH
