User Interface Software

UGS, Candle

What happened?

I repeated the problem No. 1122 "Abnormal operating speed" when the override feeds is not set to 100%. Jogging run at a very slow speed, the feed value is displayed as "nan". The sender of the G-code does not matter, I sent commands manually, and also used Candle and UGS.

commented

Can you manually show a simple way to recreate the problem in a console. I can't make the problem happen. Can you get the nan to happen without a jog command. The problem may occur before the jog command.

I don't think jogs are currently intended to be affected by overrides.

commented

Yes. I'll try to do this.

I supply power to the machine.

nan and a very low speed of movement.

commented

I can't repeat the problem with your example.

commented

The problem is very easy to repeat.
I took a new ESP32 Devkit V1 board and loaded it with firmware 3.7.17.
Then I uploaded the file fluidnc-config-files/official/MKS_DLC32_21_XYZ.yaml.
Launched WebUI.
Set the override to 110%.
Started a jog:
$J=G91 G21 F1000 X10
Controller response:
<Jog|MPos:10.003,0.000,0.000|FS:nan,0|Ov:110,100,100>.
As you can see, nan is available.

Jog

commented

Thank you for resolving this issue. I'll compile the firmware and test how it works.

commented

You don't have to compile it yourself. The Continuous Integration action that tests all Pull Requests now leaves a binary that you can download. Go to https://github.com/bdring/FluidNC/actions/runs/8930764528 and scroll down to the bottom.

commented

I'm understood, thank you.

commented

Did you test it?

commented

Yes, I checked the engraver's operation in different modes. Everything is working correctly.
Thank you, you have a great project!
