Hi Russ
Yes I have the manual. A small white book, "that was righted by the usefulness of proper and wholly the set and unset the device" , if you know what i mean

Hi Guys
I am running a Chinese VFD and spindle, with the outputs from the Leafboy going directly to the VFD.
It is a Hyuang breed of Chinese evil.
The digital inputs seem to work the same way as the onboard controls. If you push the dir button it simply toggles from for to rev. It does give the option to set a separate input for forward and reverse, running and stop, but all of these inputs run in the same way. Once you push a button, it stays active until you push another button, ergo the separate start and stop commands required. I can get everything else to work, and am currently using the stop button on the VFD to shut it down. Unfortunately this then requires the VFD to be switched off and on to work again.

This drive does apparently support RS485 comms... in a Chinese way. I have had a brief read about this on the forum, maybe it is a better way to go?

Any thoughts?
Cheers
Matt

Hi Tweakie
Thanks for the link, but I had downloaded and gone thru all of that before I even plugged the controller in I should have looked a little longer thru the forum, as it seems to be quite an ongoing thing. I reloaded (seemed to be the most common cure) with the latest version of mach3 and tried it again and all is good.
I now have it wired into my mill and running. Had a bit of trouble with the drives and ground voltage differences, damn these cheap switch-mode power supply's, but a bit of messing around with pull up resistors and whallah, motion
Spindle is next. Have you.. or anyone else, had to send a dedicated STOP signal for the spindle? The VFD I am running uses latched input's, so I can trigger FOR and REV with M3/M4, but I can't stop it. When I enter M5 the output PWM stops, but the drive still runs at the min freq, about 500rpm. Is the somewhere in the Ports&Pins or spindle config to set an output for M5?
Cheers
Matt
PS sorry if i am going off topic here

Hi
I am having the same problem now. I have just got a Leafboy77 USB motion controller, and since I have added the plugin for it, the motor tuning window will not open.
Does any one have any ideas?
Cheers
Matt

Hi all
Sorry to but in to this conversation, but I think I may have have the same problems. I my case, it was a ground voltage difference issue. I was getting a 2.3-3.2v difference in ground voltage between PC and drive board IO. It caused all sorts of these issues with random home switch triggers. I could not get an accurate home position for love nor money. It turns out that the optoisolator trigger voltage on my board was 2.4-2.5v, so as the ground voltage wavered, I was getting intermittent trigger signals for the home switches. The real problem turned out to be that I was running a switch mode power supply to the drive, which does not ref the main ground zero voltage. This allows it to run up to +/- 3.7v from supply ground, depending on supply frequency variations.
The simple answer to all of this is to run an optoisolated IO board. The optoisolation should generate the required 0-5v switching required for general logic transfer on both sides of the voltage difference.
I hope this helps.
Cheers
Matt
