As I mentioned in a help post earlier, finally broke down (literally) and got a Carbide VFD. After all the hype by the majority of this board (seems like anyway) just couldn’t take it anymore with a need to work with the best. Took little time and virtually no swearing to install despite the spindle cable has no connector at the box necessitating me to pop the chains twice. I was surprised at how easy it was to add to Motion 613 even though it requires a complete machine setup as there is no access to the menus any longer.
Let me say I was impressed just seeing the spindle spin and cut like Tesla compared to Makita. If you don’t have one, suggest you consider it.
Trying to get my head around the fact the RPMs on the meter are off 5-10%, with no means of compensating. I can adjust the RPMs in the file to compensate if the performance doesn’t vary, I think, but why? I exclusively cut acrylic and 1500 RPM deviation can be an issue, it was a primary factor in caving into the VFD.
I’m not sure what the buttons are for other than to change from HZ to RPM. And what does the knob do, anything meaningful? I mean you would think there would be a diagram of the controls, what doesn’t?
I would think you could compensate for the RPM deviation with the existing potentiometer adjusting the voltage, in addition to adding an RPM bypass. From reading through research regarding VFD Spindles in general, these features should be expected.
Appreciate any comments to improve my spindle education from the Pro Spindlers out there.
