CNC feedrate not changing to Fusion 360 and touchscreen parameters

Snapmaker 2.0
1

Hello all,
This is my first time using the Snapmaker 2.0 200W CNC with Fusion 360. I’m starting out with just a simple facing operation, and I want only climb direction cutting.

I set all the feedrates in the tool section of Fusion, to around 900 mm/min cutting feedrate. I want the transition part where the machine isn’t cutting anything to be faster, so I set it to be 3500 mm/min.

The touchscreen does display the correct work speeds, but clearly the CNC moves at a slow constant rate, regardless of whether it is cutting or not. So I suspect this is an issue regarding the touchscreen to CNC interface. I also notice the touchscreen software itself is pretty buggy (for example, the progress display is completely wrong and random).

If anyone could suggest solutions to making the CNC actually run at the feedrates I entered in Fusion and that the touchscreen displays, that would be great.

Also, I’m a newbie at CNC, and 900 mm/min was recommended on the Snapmaker website. 3500 mm/min was just a speed I thought the machine can handle, while being fairly fast.

If you are using the free version of Fusion 360 and the standard post processor by Snapmaker, your travel speeds will be limited. Fusion limits the travel speeds in the free version. However, someone has modified the post processor to allow faster travel speeds. I could not find it quickly, but if you need that one, I’ll dig a bit deeper when I have more time at my hands.

That said, the touch screen display only refreshes only in slow intervals, so what you see may diverge from reality at times.
