It sounds to me that the motors are tuned too high. I guess that you could simply replace the nuts with the newer anti back lash style, provided that the screws are Acme thread. I have a K-2514 and it runs fine with delrin anti backlash nuts, they came as stock items. I use Mach 3 as a control software. Tuning utility is included based on distance traveled and accuracy. If you can't get them from K2 try doing a search here for them. |
