I am in need of some help. In mb2hal.ini transaction 02, I can not get the set speed working. The crash message states that " mb2hal.spindle-set-speed does not exist ". I have stated it in the custom_postgui.hal file. I am wanting to have the " run speed slider " populate the set speed parameter in the drive.
Transactions 00 and 01 work fine

Any ideas would be appreciated.

Hal files are loaded in sequence as listed in the ini file, is the ordering there set correctly?
Check for typos in the pin names.
Check the ordering of hal files as if you call on a pin that has not yet been loaded, it will fail.
