Alright... So let me give you a quick run down...
Stable settings.
XHC 4 Axis motion card
Wantai DQ86MA drivers
Y Axis. 1250in/oz motor @ 350in/m 20in/s accell @ 4.0a RMS 5 microsteps(1000pulse/rev)
X Axis 1100in/oz motor @ 500in/m 50in/s accell @ 3.5a RMS 5 microsteps(1000pulse/rev)
- I've done roughly a 4:1 gear reduction through pulleys.
- Both X and Y have their own independent 60v 6.5amp power supplies, so power should not be an issue...
- Sherline 1/2 pulse mode is engaged, as far as I understand this is for signal smoothing, but I don't really know its function?
- I've played with Kernal speed, but don't see a direct change in anything.
- I use Half Current setting (on the holding current), when I set to Full Current, it stalls almost immediately... In fact, Generally when I drop the amperage, it performs smoother...
I would like to increase the speeds for fast travel as much as possible... even thinking close 1000in/min should be attainable, but when I set above these speeds, individual axis will travel, but combined motions will cause the movement to stall...
Someone suggested that the drivers may not be quality enough to output a clean signal at this rate... but I don't have a Oscilloscope to check this....
Attached is my stable XML. What are your opinions? Am I being unrealistic, and have too high expectations of these motors? Or should I invest in some heavy shielded USB cable?
Thanks!
