Some updates for you all. The mill has been working alright. My Z axis needed a little improvement on the mounting plate, so I worked on that over the course of a few days and it turned out well. It...

Here are a few pics of an attempt at milling a limit switch mount out of some piece of trash composite material. Didn't work well at all since it decided to melt and rip. There were supposed to be...

Small updates... I have one limit switch per axis wired up now in a way that will just have to do for now, haha. Test milled a small .100 radius circle under CNC so far as a quick test. Hopefully...

Wired up the motors. Gave all axis a little test drive. Everything works great so far! :D
The only motor that moves is the X axis motor, so that makes the wiring pretty easy not having to worry...

OK, basic machine is together now. I used it to manually make some modifications to the motor mounts (pics below). All motors are now mounted up. Decided to directly drive the Z axis without a belt....

Added table and way covers today. Table is two pieces of 1x3" extrusion, making total table area of 6x16". The way covers were kindof hacked together with rubber laying around, but turned out pretty...

Thanks for the reply. Yes, I completely agree that there should be more support for the column. I got the idea of using the 3x6" extrusion for the column with threaded rod through the length from...

OK. Three axis are assembled. Just need to tweak the alignment and add the table top. I already fooled with it to elongate the ballscrew nut mount holes on the X axis saddle plate, and once it was...

Another weekend, a little more progress.
I've mostly assembled the Z-axis. Just needs a bit of tweaking and counterboring some of the holes for the screws. The rods are just a slip fit into the end...

Ok, weekend again, so I might work on a few things. Yesterday I put together the motor mount for the taig spindle and an old treadmill motor. I used a thick piece of sample 'plastic lumber' that has...

Smallish updates:

Drilled holes in the base for the 8 threaded rods through the column. Drilled the large holes in the end plates for the Z axis assembly. Taig spindle has been ordered.

Those were my thoughts as well, and probably what I will go with. I still plan on using the two 1/2 plates, that way each axis will be assembled and simply bolted together. It should allow for some...

Thanks. Yeah, I'm going to buy some allen head screws. I have an 800W chinese spindle, but no VFD, so I might end up just getting an X2 head to start and wait for a good deal on a VFD to come along...

I've been delayed a bit with other responsibilities, and the fact that I've ordered more parts that I want to wait for. I've scored a large base with blanchard ground aluminum flat top from eBay that...

I have purchased a .8kW water cooled spindle. The outside is stamped as 5 amps. Anyone have and ideas for a cheap VFD?

Will a 1hp VFD run it alright? Or should I go up to 2HP, such as a hitachi...

Ok, laid out the X axis. Will drill and bolt together tomorrow for a test. I ordered a Chinese 800w water cooled spindle to start with. Still need a vfd though... Probably will pay more for a vfd...

Mini update: Received new dial indicators and new set of linear rails. Too much other stuff to do tonight, so I will update you with more visuals tomorrow afternoon.
Still looking for suggestions on...

Ok, first a little background. I am in college, always get started on projects over breaks, then they fade out over the semester. Anyway, a couple years back, I bought some random linear bearings and...

You will need a 5V power supply to connect to the +5V and respective GND connection to supply the board power.

UPDATE:

I received my replacement chips and have successfully soldered one in place. I used the method of removing the blown one by cutting the leads carefully, pulling the chip out, then...

Just make sure you dont get one that draws too many amps that would blow your controller. Find out what the max current is for the components on your driver board. Get a motor that uses less amps...

There is definitely a max length issue, and it depends on many variables. I don't have direct experience with this, but my electronics background leads me to think of a few things right away: ...

It doesn't really make sense what you want to do. Stopping faster than simply stopping and locking the motors is like saying you want to travel back in time or something so that it can happen faster....

There are devices called "Stepper Motor Brakes" that activate to stop the motion when the driver stops sending pulse signals. I am unsure of exactly how they work, but I assume they are meant to...

Yes, it is the same. (TB6560AHQ)
The only problem with digikey is high shipping. (only $2.41 for usps, but my ebay purchase was cheaper).

Thanks for the links and info. The way these chips are mounted, it would probably be hard, if not impossible, to use a socket. They are not through hole, and not a regular surface mount. There is a...

Well, I'm still waiting on the arrival of the chips since I ordered direct from china. Should be here in a week, 2 at most. I've done electronics work before, and these chips look fairly simple to...

Foudn the correct pinout for the powermax motors: http://www.pacsci.com/support/documents/stepper/powermaxinstallbulletin.pdf

I did have it slightly wired wrong, possibly drawing more amps.

Eh, with shipping that would be about $22 a piece, more expensive.

The bad motor was one of these: http://business.shop.ebay.com/Drives-Motion-Control-/78186/i.html?_catref=1&_fln=1&_ipg=&_ssn=cowdaman&_trksid=p3286.c0.m282

Can get those for cheap but that guy's...
