Unable to change spindle speed

[dbrannen]

Spindle speed is not changing on our PRS Standard with 2.2 hp spindle. The only post processor options we have in VCarve Pro are what you see below. I searched through the forums here and somebody mentioned that the post processor with "ShopBot Arc (inch)w/speed(*.sbp)" as the option that allows for automatic speed changes. We have VCarve Pro version 8.014

Thanks in advance for your help with this!

As if I didn't sound ignorant enough, I cannot notice a rpm change when running the spindle warm up routine either. Unless it is such a subtle variation in pitch...can't imagine that it cannot be heard.

Do you have the VFD/spindle rpm USB controller hooked up and if so, do you have the spindle control tool/program running (Tools/spindle rpm control). Click in the rpm window to apply the appropriate settings for your VFD/spindle. If you do have this all in place, can you change the rpm by clicking in the rpm window and entering a new value. The TC inch post will control rpm.

I'll give your suggestions a shot as soon as I get back to work. Thank you Scott!

What a difference a new day makes. I got in to work this morning and started the spindle control program and I was able to change speeds by entering new values. When I took a look at the rpm window, I did not have the spindle control set to open when sb3 started up. Ran the warmup program and everything works great!

Thank you for your help Scott!
