G540 4 axis package (1PCS G540 +4 pcs KL23H2100-30-4B (3/8” Dual
shaft with a flat) 382 oz-in + 1 pcs KL-350-48 48V/7.3A 110V/230V
power supply): $549.95
I have heard a lot of good things about the Gecko products, and although I couldn't tell you one bit about how they are different from anything else, I think I will be thanking myself in a year if I spend the extra $180 on this set instead.
Too bad I won't be able to cut aluminum, but it's not the end of the world! And a great excuse to build another CNC down the road.
Since I have your ear, can you recommend a good replacement for the Dremel for this application, that would work well with MDF and give me a little more cutting power?
Thanks again! |
The major benefits to Geckos are as follows.
1. Unparalleled support.
2. Mid band instability compensation. electronically prevents the motor from stalling unless you overload it.
3. Quite operation. will not buzz and squeal when idle like chopper drives.
4. Morphing from microstep to full step on the fly. This gives the best resolution at low speeds and max torque at high speeds.
5. 50v operation for great rapids fom a low priced package.
6. 4 axis drivers included
7. Integrated breakout board for computer protection.
8. Integrated 0-10v anaolog output to drive a vfd/dc motor control. great for that mill and lathe in your future.
9 Did I mention the great customer support.
10.Very conservative ratings on internal components so risk of failure is minimal.

I have used both the Dremel (Not good), and rotozip with plastic housing (better but still lacking). I am working on mounting a 2hp router to my cnc router and I will see.
