Having some problems starting VFD Spindle in gSender and UGS

Hi all,

I have a chinese VFD spindle (from Anolex, as my cnc machine), that I can start/stop from Candle. But I can't get the same command to work from either gSender or UGS.

The machine has contact with both software, XYZ axes work, homing works, but M3 Sxxxxx command doesn't work.

I was asking earlier about alternatives to Candle, because I don't want to use it anymore; but I can't get the other 2 most popular software to get my spindle to turn.

I tried almost everything that I can think and have found on forums etc. Anybody has a clue what the issue can be?

I tried running all 4 latest official release versions of gSender and the latest UGS.

Btw; Candle can't turn the Spindle on start-up either. I have to engage the E-stop on the CNC Controller (Anolex Evo Ultra 2), and release; then Candle can turn the spindle. But this weird workflow does not work in the other 2 software.

Help! :(

GRBL control software, which is your favorite in 2026?

Which is your favorite GRBL software as of now?

I started this hobby with using Candle (on Mac OS) and it was okay to start with, but I am really starting to find almost everything about it annoying. Including every aspect of zeroing axes.

There some posts from 3-4 years ago regarding this, uGS comes up a lot. But haven't seen anything from recent months.

I have an Anolex 4060 Evo 2 Ultra, and it runs on GRBL 1.3a. And I use Fusion as CAM.

The software doesn't have to be Mac OS compatible, but it's a positive if it is and I don't mind if it's a paid software, as long as it's actually working well. I am looking forward to uninstall Candle!

P.s. I work only with wood, build electric guitars. Only 3 axes

Mac OS 15.7 Sequoia and Candle 10.12, Z Probe settings are missing. How to set up a probe?

Hi,

I am running Candle on Mac OS, and there seems to be missing settings pages compared to the Windows version. Specifically, the option to input the thickness of the Z-probe that I am using.

Program executes the command to run Z-probe, and contact seems to be creating some sort of info, but since I can't really input any value of the specific Z-probe that I have, it doesn't really work.

There is a script command under "user commands", but it's not something that I understand. Seems editable, but complicated for my level of knowledge. It's as follows:

app.device.storeParserState();

app.device.sendCommands([

"G21G91",

"G38.2Z-30F100",

"G0Z1",

"G38.2Z-2F10",

"G92Z0",

"G91G0Z5"

]);

app.device.waitResponses();

app.device.restoreParserState();

This seems to be only place I can do anything about Z probe height, but I have no clue how.

Can someone help please?
