hi there. I am new to the CNC world. I hope to love working with the second hand desktop CNC I recently bought. But am have some problems. i was trying to change the speed settings on VFD and mistakenly cleaned all the settings back to their default. The machine is an itech k6090t CNC with is the same as a laguna IQ with a delta sm300 VFD. It runs a 2.2kw water-cooled spindle, the controller is rich auto A11E. If anyone has the setting that would be a great help.
