Here are some links to my new Grex based router controller. This is powering
(3) 640 Oz/In Nema 34 stepper motors.

Cool, where did yo get that rackmount case, any links?

Have you cut anything with the Grex, hooked up to your router?

I haven't cut anything with it yet. but ran the motors for about 6 hours today. seems to be real smooth running from the latest Mach3 version.

Thanks!

Really nice to sse the G100. It should be very smooth and very, very fast. Compare Mach3 running from a parallel port. It will sound like a barrel full of monkeys. Compare Mach3 running on a G100. No sound effects at all.:-)

Excellent Job. I will be monitoring this thread.

That looks nice!!!

I have one question. The G-Rex G-100 works with Servos too?, just changing the stepper controllers for G320 geckos, or it only works with stepper motor drives??

Since Im only finishing my HobbyCNC kit and still have linited experience, Im a bit confused about the GRex controller. You seem to have the controller in your box PLUS 3 other items....drives maybe?

If you buy the GRex are the microstep drives included?

Why do I only need the driver board with my HCNC kit, but you need 3 driver boards and the GRex Controller?

Thanks.

[Ed_R]

Your HCNC has three drives in it, integrated onto one drive board. The Gecko drives are separated .

[diarmaid]

Thanks.

The G100 replaces the parallel port and breakout board (s). It doesn't take the place of the drives. The G100 creates the step and direction signals, much cleaner and faster than the parallel port. Where the parallel port is limited to 45000 steps per second with Mach3, the G100 can output 4,000,000 steps per second.

If you wanted to, you can connect the hobbyCNC drives or Xylotex drives to a G100. Any drives that accept step and direction should work, either stepper or servo.

where do you get your power supply? I am looking to the exact same thing but with 4axes.

[diarmaid]

If Im not mistaken the power supply just looks like a torodial transformer....

So how do you input to the G100 from your computer if not using a parallel port?

[the4thseal]

i know what it looks like but i would like to know where to get one. It would be nice to know where to call and order one. I am not a big fan of messing with power supplies.

[Yepez]

Thanks for the info Ger21, That's mean to update my Servo sistem at present using 3 G320 geckos, 3 DC servos controlled trought Parallel port.

I Just need to add 1 Grex G-100, and I can get 4,000,000 steps per second, and this Grex will be controlled by the Ethernet or USB port, right?

Thanks!!!

[Yepez]

One more thing? How many Inputs and outputs does this G-rex G100 have???


Thanks!!!

I don't know for sure if you can get the full 4Mhz step rate with Mach3. And if using mach3, you can't use the USB. Also keep in mind that Mach3's G100 support is not yet complete, although may be functional enough for your use.

Looks good. But I notcied one thing. I can't see the 470 UF caps on terminals 1 and 3 of the G201. While your motors may run smooth the internal 100 uf cap may be getting warm or even hot due to the length of the wires you have from the cap to the drivers. The only way to tell is to remove the cover.
I always install the caps that gecko recommends across these two terminals.

If the G100 will do that, would there be a performance differance between a G201 and a G202 if both were running with the GREX ??

[Dan Mauch]

Not sured if I should jump in here but the G201 and G202 performance will be identical . Similarly the new G203 will have the same performance as the G201 and G202. The advantage of the G202 and the G203 over the G 201 are the short circuit protection and other features.
I recently tested some G201 and some G203 on my mill drill using mach3 with a G100 and got 110 IPM on my mill drill out of both of them. I had Mach3 set for 256 khz.
