I thought the r7 spindle could be controlled by tinyG? I have to turn the dial on the inverter to make the spindle spin. I have the spindle hooked to tinyG but nothing.
You have to program the inverter to accept the commands. If you can use the pot to adjust the speed then your settings are wrong. Search you tube for now forever vfd. There’s a fella with a Chinese cnc that goes through it. I found a manual in English somewhere on line. Don’t remember where but it’s out there. If I remember correctly it’s not a straight forward set up with the TG. Brandon did a vid on it a while back.
CNCJ is the you tube poster. He has the link to the English manual with the video.
@Curtis_Cummings thanks. I will look for it. It’s funny I looked up videos for everything else. I just didn’t think about this. I guess my Alzheimer’s is acting up.
@Edward_Bigham I’m sorry. Who are you and what are you talking about.
@Curtis_Cummings lol. That’s how I feel sometimes.
By the way guys the manual is on the R7 site. The connections are in the comments of the R7/OX wiring example video.
Here is how I have mine wired. I have Tinyg, Now forever vfd and 800w spindle.
I have from the TinyG PWM to the VFD A1N1 Lower Tier
The ground on the TinyG to the VFD Com Lower Tier
And Jump out the X1 to Com on upper level.
With this the TinyG will control it but it will only go up to 63 hertz.
Any help would be great.
Thanks in advance.
It sounds like we need an R7 wiki?
I think I hooked it up according to the information that Brandon provided. It is just not coming up to speed. So far I am baffled.
I have not hooked mine up yet but I believe there was a setting in the VFD to map the voltage to the RPM?
Here is a copy of the manual:

I see there are jumpers and settings that must be correct.
@Edward_Bigham what is the max voltage input set at in the VFD? The comments at the end of the video are for the M1. It is 10v out, well 10.6 but that’s another issue.
400hz/ 3 (because 3.3 x 3 is almost 10v) is 133. So there might be something else.
Have you changed the TinyG settings?
A lot to this guys. The TinyG and VFD settings are required to be changed. I unfortunately can’t say stick A into slot B. The information is out there though.
@Colin_Kaminski we could do this in the forum it would be easier to search. The wiki was an issue, can’t recall why… think it was something of a commercial issue.
I do like G+, but it is a little hard to search. For instance the above topic has come up and the answer to this question is in here somewhere.
Problem with the controllers is we don’t make them, they are just offered with the R7. Slowly trying to change this. It does get convoluted with so many different settings on the TinyG.
@Colin_Kaminski there are parameters you have to set in the vfd. I set them but I will double check them this weekend. It’s not that big of a deal but I would like to head off the problem of me not turning the spindle on and it just rips the bit off. Lol
If you start moving jumpers and such record how things were.
@Brandon_Satterfield I’m not going to move anything. I am just going to check that it is setup according to the instructions SMW3D set forth.
Is the way I described my hook up correct?
Also it might have to do with cnc.js.
Thanks
Hi Ed, yeah sounds correct.
The R7 site has the manual to the VFD.
Scroll through the manual. You should be able to basically run cover to cover in 20 min. A lot of valuable information the manufacturer put in there. I.E. I have my deceleration and accelerations tweaked as well.
There has been guys post about the TinyG and VFD settings as well. It’s fun to play with all of it.
There is a bit of a non-linear fit on the TinyG. There are post about it here as well somewhere. My personal advice, don’t go down this path, getting a perfect match through the entire RPM range would require some deep research and coding experience. Find the RPM range in the mid (12000) make it match and you’ll be perfect from there.
@Brandon_Satterfield that is my thoughts as well. I will just check the jumpers and make sure that they were setup correctly from the manufacturer.
Like I said it might be a conflict with cncjs. I don’t think anyone here is running cncjs to confirm that.
The GCode header will tell you if cncjs is the problem.
