I agree Leeway,

I didn't bring up this issue to be contentious, but to get back to work. This isn't a hobby for me and these problems have cost me untold thousands of dollars and hours of...

Mariss,

Do you still have my credit card information? If not, do you need my home address to send the refund to?

Most of you know the problems I have been having with my gecko 202's. For those who don't, I've been running my 202's for almost a year. They have faulted over and over again. I have returned them...

I replaced the two 202's on my x axis with 201's. I ran for 59 minutes with no problems whatsoever then the y axis quit. It still has the 202 on it!

Awsome. Easy to understand. I'll bet almost everyone reading your post did the thumb and finger routine!

Running the steppers serially will be my last resort. I am about to say that the 202's...

I bumped it back up to 6 amps by putting 270k resistors on all of the axis'.

I am grateful for all of the help that I am getting from end users. Here is a thread about the same problem from...

Crevice,

Thanks for taking interest in this topic;

My pc is a Dell 2.4Ghz Celeron with 512 mb of RAM. I am running mach3 and the kernel speed is set at 45000 Hz.

The 212 was in one of...

IT'S 202's not 201's as in the thread title.


SORRY.....

Still faulting even after installing new power supply. see "recurring problem no holding torque" thread.

Crevice,

Put the new transformer on today and it made the gecko's fault quicker if anything. The motors that I have are supposed to be fine at the aforementioned voltage but I will try the serial...

Hello Angelo and Crevice,

Over the course of a year of problems you guys were the ones who helped me find out that my power supply was under-amped. Stan H. is sending me another toroidal...

I think it is the power supply that is causing the years worth of problems that I have had. It's under amped for the job.

Crevice,

My power supply is a 800va model y236907 from partsexpress.com rated as follows
45+45 VAC
8.89Amps

My 4 steppers are 960 oz rated at 7 amps wired parallel with inductance of 2 +- 20%...

The problem that you describe is exactly the problem that I am having with my machine.

I have 960 oz steppers from homeshopcnc that are rated at 7 amps I also have the PMDX 131 breakout board and...

We've gone around on this before but now I think the issue may be the motors. I have put 120K resistors on all drives but they still fault over time. Maybe 10 minutes will pass, but one or both x...

Since I put the 270K resistors on my two x drives I haven't had a problem. I haven't run the machine for more than about 20 minutes at a time yet but all looks good so far. I am going to run some...

Mariss et al,

I had no intention of badmouthing the Gecko. I was merely pointing out what I had read on another forum. Those were they guys badmouthing the Gecko drive, not me. Here's the link...

God I hate this tit for tat. Somebody made a mistake.

You sent me out a replacement and I sent the first drive back to you. The replacement drive that I still have has the letters J7 in the...

To all,

Feel free to go to UPS.com and track the shipment I made to Gecko last year.

Here is the tracking no. from UPS 1z10w5a40380989230 It was delivered to Gecko on October the 11th at...

Thanks for the reply Ger21,

Yes, I have done everything that can be done to diagnose the problem. Here is what I have done:

Checked all wiring for tightness
checked the seating of the wago...

You are making me out to be a thief. I paid for those drives and sent them to back to you for testing one at a time. I have the original bill of sale from your company for 4 drives. I only have...

Thanks for replying Marcus,

The drive shuts down and the motor freewheels. My machine is pretty tight and I can almost cut with one side running, but not quite. The control box on this machine...

I guess that I'll do like the guy with the 203v's that are randomly faulting and get some 6 amp resistors and try that.

Marcus,

Is Mariss your dad?

I talked with your dad? earlier today on the phone. I did have a known good drive in my cnc machine for about 6 months until the owner asked for it back. That's...

I've gotta give Mariss kudos first. He has tried to help.

I have 4 G202's on a 3 axis machine. 2 of them run the X axis.

RZBKRAIN,

I got the pinion gears from Mcmaster Carr and the rack from Standard Steel.

chevdrgtrk,

It's the dell. I don't have servos but I don't know if that matters in this situation. What I do know is that I ran these steppers on 3 different Dell machines and only the 3100...

Woodcrafter,

I didn't use any aluminum because of the high cost. I was able to pour a polymer to level out the gantry. Worked great. I have perfect (and I mean perfect) perpendicular on the...

I just finished a machine that I designed and built with my brother. He's a machinist/jig&fixture guy at an aircraft factory. This machine took two months to build on the weekends. I have more...

I have two computers on the tabletop. One is the new(bad?) 3100 and the other is my kids old 2400. Both are Dells. The 3100 is running without anything on it except XP and Mach. The 2400 is...
