G540 - 4 motor connection problem

[dachopper]

We will see, if the new power supply fixes the problem, I'm happy. If not I will probably try the leadshine the am882 quite cheap now it's no longer made, much different to new em series? . It's by no means a "cheap" change so we will see.

I did get my x axis running at 18,000 mm/min when I changed to the 42 volt pwr from 30 volt, so I should get another increase going to the max 50.

To clarify gecko tech support told me that 48 volt should be fine to use, and anything up to 50 volt should be fine with this system. IE it is designed and tested to run at higher voltages, and downrated to 50 volts for the consumer to avoid issues and to include a large enough safety buffer. Anything that fails below 50 is an anomaly.

All I can say is you have the syndrome. As was pointed out in the original post kits are very seldom a matched set of parts. Go with AM882 and 68V PS and you will have a different machine .

Is $40 per am882 a good price?

I would say very good but check the del charge

I do not think you can get them at that price. Be careful not to get defective units/ factory rejects or something. I got them at $75 with free standard shipping or at additional cost for DHL/UPS

I'll warn you again because don't care what Gecko says, if you run those drives at 50V you will considerably shorten there life.!!

If you can get AM882 for $40 then buy them instantly. Feed them 60v+ and watch your machine dance like never before.
