Did you ever find pulleys for this? Im looking for pulley options for my mill now too.

I must have had the +- inputs flipped in on the ribbon. I checked my voltages and plugged then into what seemed right and BAM axis moves. Pretty excited. No I just need to find a better wire hook up...

Enable on those mondo steps is set automatically if left unplugged so that's the way I have it. The driver is always enabled.

yes both. thats whats so damn confusing

I have a used Syil X4 that the previous owner tried replacing the the Z axis motor and driver on. After spending about 8 hours trying to understand why Im not getting anywhere Im finally asking for...

My Laser from Ebay came with the same software, and is essentially the same unit. Plan for 450$ to upgrade to the light object controller, 200 for a PWM power supply, 100 for stepper drivers and...

your youtube links say the videos are removed. Thats why I asked, but I appreciate the feedback. Im looking forward to getting it.

What Problem are you having? I literally just bought one last night instead of the 608

The thing says it supports it, but Marco isn't sure how to do it. Heres the background of whats going on.

Im using this power supply. NEW 40W CO2 LASER POWER SUPPLY | Automation Technology Inc
...

Nope, no access to an o-scope. But I've checked with a volt meter. So that's as good as I've got. :)

Ill play with a couple things and see if I can get some results.

40v on 50v max drivers is "low"? The power supply is a toroidal 40v power supply and never caused an issue before, but no I cant change the voltage. These are the step timings Im using currently:
...

Any input on the stepper timing? I cant look at the previous settings because the hard drive died on the last computer so Im not sure what they were like last time.

Interference is a maybe, but I doubt it.

The Computer is very different, but has been used for over a year to power a different machine so I know it works well. Its a 1.8ghz P4 with 512 ram...

I have 3 5056 drivers being powered by a 40v 10amp power supply. I am running 3 400oz in 4.09amp current setting. They are running with sw4 in the in "on" position and in 1/8th step micro stepping.

Grizzly is supposed to be getting back to me on monday, Well see what they have to say. The issue doesnt seem to be getting any better, but its not getting worse at least.

Do you know if thats in the first or second thread? 500 pages of thread is alot to sift through :)

Awesome, so probably another bad board. I love buying broken stuff :)

Hey Guys! I got my new G0704 2 days ago and am really loving it except for one thing. The speed controller on the spindle motor does not seem to be stable. I ran the break in for the spindle bearings...

Hey Al, Where did you find that Info? I cant find much for this box and the documentation I got with it is very limited. Thanks for your help!

To be honest Im not sure.

I have a complete KBMD box, enclosure and reversing switch. Im now sure which of those boards/methods would be best for that controller.

no one?

I recently built a new control for my cnc router. The router has been working for over a year, but I decided to rebuild the control with better drivers. The current configuration is as follows

I have a KDMD 240D controller and a 2.5 hp treadmill motor that I would like to use for a DC motor conversion on my 9x20 and would also like to connect it to a my PC I plan to use in my cnc...

I just got a Mill. and have lots of delrin and some scrap 1/2-10 5 start, and a 1/4" ball mill on the way. Guess what Ill be doing this weekend. Ill post up some results

Im assuming with the size of the lathe I am never going to push 100 ipm. On my router I am using 5 start 1/2-10 screws and I can push 500 ipm pretty easily, with the motors Im planning to use of the...

This could easily happen with a bad connection some where and may be the cause of what your seeing,

The other thing I would look into is (your going to hate this) unhooking the gantry and running...

There was a big controversy over the original project these guys did. The main guy was pretty active in the FireBall V90 Yahoo group until his router kickstarter came out and people called it a...

Im starting to gather info and the such to convert my 9x20 lathe to cnc. Most of the parts Im going to make will be turned in acrylic or Delrin but I would like to have the option of using mild steel...

This is exciting to see someone that is actually going to finish their conversion. I've had my lathe for over a year waiting to be converted. Were you able to find a maintenance manual for the lathe?

Ive bought 2 3axis kits from Probotix. (2 different machines)

Fantastic product and amazing support. These guys really love hobby cnc and what they do. Highly recommend them.
