They look like very nice drives but wow about $200 USD +S&H to the USA a bit steep is there anything made here in the USA that would do the same?

(;-) Now you have entered the CATCH22 zone. Big motors ,Big Hurry , BIG drives  BIGGER price tag.

yOu can LOOK aroound BUT you have to be REAL carefully of what you buy for the older DC motors. You may require step/dir control and most older drives for the BIG motors were analog. AND you never know how old or used the used ones can be.

The ac drives (step/Direction)I use here NEW are about $800 each. The Mazaks here are $1800 ea refurbished.

AN option may be to replace the "motors" with something MORE compatible to the lower end drives you have.  That and a little gearing MAY solve your problem and allow you a lower cost replacement IF you loose a drive along the way.

Just a thought, (;-) TP

You can get the Dugongs in the USA from CNC4PC I believe. There will be USA drives of similar specs I am sure but they will be Industrial marketed drives and will be more expensive. There are the Vipers and Rutex drives but lots of bad in amongst the good reports on them.

The Larken drives were the Vipers I mentioned above. I have never used them so cant give you first hand experience but there are good and bad stories about. Suppose that can be said of most drives in this sector of the market but not heard any issues with the Dugongs yet.

Would you think that the code could have anything to do with the drives faulting out i was running the machine everything was going well no problem then about @ line 7652 the drives faulted out coming out of an arc man what a pain.
