Issues found with Trackspot - Poor Movement and error tones

After receiving back our 4 trackspots from a repair shop, we have discovered that one of them was making error tones that prevented the entire light from responding to a self-test or a respond to dmx. Another refused to respond to dmx with no dial tone. The biggest issue I have is with the ones that are currently working. The pan and tilt movement is horribly slow and it takes a solid minute to move from place to place across our venue. I have used both the patch provided inside of our console's library, as well as create my own custom patch. I am using an ETC SmartFade ML.

If anyone could help me with these problems it would be a big help.

Thanks and God Bless,
Taylor B.
