Huanyang VFD control plugin for Mach3, USB RS-485

Hi Martin,

Please forgive my ignorance, but have you set a target spindle speed in the dro before pressing the spindle start button? I was playing around with it for a good hour before I realised I hadn't set a speed, lol! That and what really made a difference was to reset the vfd to factory settings then enter all your parameters fresh, I think there is a certain order it likes it to be done in, I found some instructions that said that and it worked for me anyway. I was ready to throw the damn thing out of the window before I managed to get it going, then its the best thing ever :) Just in case you are experiencing any problems with interference, I used an old serial cable that was shielded, just used 2 cores and grounded the shield to my pc case. Worked very well for testing purposes. My machine isn't to a stage where I can tests its reliability for cutting yet though.

I wish you the best of luck with getting it fully working.

Sure it must be down to something I have done or haven't done lol but at the moment it's finding the time to sit down & work through problems. Machine works fine with the other plugin for cutting so there is no immediate rush. Think I will take your advice at some point though & start from scratch again, will reset the VFD to factory settings so I know where I am going & re enter all the values I need to change. Don't think it's an interference problem as the VFD must be communicating with the other plugin. Did originally use a bit of cy cable to connect but replaced that with a bit of shielded twisted pair after reading Jays comments.
