Huanyang VFD control plugin for Mach3, USB RS-485

[JayPunchbuggy]

Hi,
Im not sure why its not working, sorry. However, The comments from the author might help.

I just read them over again and remembered this setting that needed to be changed:

"In Mach3 under Ports & Pins -> Spindle Setup ensure Disable Spindle Relays is unchecked under « Relay Control »Restart Mach3."

If that doesn't help, the author of the plug in might be able to assist. Once it works, it really is great. Good luck!

Hi Jay,

Thanks for your fast reply! I've actually had a bit of a breakthrough... I think a combination of things were holding me back, but the noticeable one was to do with the monitoring section of the plugin configuration screen. The author of the page you provided the link to suggested that you could monitor a certain status from the vfd, have it displayed in a dro and set and estop threshold of a given unit. Following his advice I set a value for the estop threshold for one of the drop down options and forgot about it, it wasn't until I checked every single option that I found my mistake.

The vfd now tries to run without the spindle connected. However, when I did connect the spindle the vfd throws a fault of open connection and forces an estop condition, which is actually damn clever :) I think perhaps a connection has come loose on the crappy chinese spindle plug / socket. More investigation is required, but I'm chuffed that the plugin is working enough for me to get this far. Hopefully it'll play ball when I put it through more testing soon

Thanks for your help!

Had another look at the weekend & still have a problem with the plugin tripping mach3 as soon as I try to start the spindle.
The other plugin that is on the mach3 forum is a bit strange as well. If I start mach3 from scratch & press the spindle start there is a click & the button flashes yellow but the spindle doesn't start. If I load some gcode & run it the spindle starts, runs & stops as it should. If I then try pressing the spindle start button again the spindle starts & I can also change the speed, pressing the button again stops the spindle as it should, can do that all day long until I shut mach3 down. When I start it up again we are back to not being able to start the spindle until I have run some code.
Not really a problem as it seems to work ok when cutting anything but just seems a bit strange.

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.
