Re: Limit Feedrate in GCode G1

Hi Fredric, Thanks for the complete explanation. You are correct. There are several flaws in the KM_Axis/KM_AxisGroup classes. I don't think anyone has been using the KM_AxisGroup.EnableGroup call to set the Motion Parameters. We're thinking to make the following changes to KM_Axis/KM_AxisGroup: Vel...

Re: .Net library missing functionalities

Here is an article on how the Trajectory planner handles small segments. The test case is a 90degree 1 inch radius arc made of 30 segments with 3 degree direction changes executed at 5.5 inches/sec (330ipm). To smooth the path the Trajectory planner uses segments with 0.5 degree angle changes (180 s...

Re: Limit Feedrate in GCode G1

Hi Fredric, I think the issue is with confusion with mm vs inches. I confirm my issue also with KMotionCNC: ToolSetup settings: X 1000 counts/inch | Vel 150 | Accel 720 RapidAsFeed unchecked What are the units? I assume mm? Are you saying KMotionCNC limits Rapids properly? Is your system 1000 counts...

Re: Limit Feedrate in GCode G1

Hi Fredric,

I don't think so as long as Velocity and Acceleration are specified as values in Inches/s and Inches/s^2

Maybe I'm missing something.

Re: Limit Feedrate in GCode G1

Hi Fredric, There are different Axis Constraints for Rapid moves vs Feeds. Rapid (and Independent) moves are performed as 3rd order motions with constraints on Velocity, Acceleration and Jerk specified in KFLOP/Kogna. Feeds are performed as 2nd order motions with constraints of Velocity and Accelera...

Re: CPU usage

Hi Alexanders, Thanks for pointing that out. KMotionServer searches for Ethernet Adapters to broadcast multicast packets to try to find a Kogna. When no Ethernet Adapters are available it ends up in a tight loop searching for them. My W10 i7 PC shows ~7% CPU usage in that case. Adding a 250ms Sleep ...

Re: .Net library missing functionalities

Hi Fredric, Thanks for the info. I will evaluate the possible latency due to the "GCode interpreter + Trajectory planner" being hosted in the PC. Our customers are using Gcode programs (3D milling) with very small segments at a high rate. The machine should not wait for the coordinated motions comin...

Re: .Net library missing functionalities

Hi Fredric, Please can you add the following Property for the next release: KM_Interpreter_SetupParams.DoRapidAsFeeds I verified and you already implemented the needed interops in KMotion_dotNet_Interop.cpp Just the .Net property using those is missing ;) Yes we will add. Do you need a patch now? My...

Re: KOGNA RS485 SLAVE ID

Hi kizilkaya, Attached is an example that should read the 8 Inputs to Kogna Virtual Bits 48-55 and write Virtual Bits 56-63 to the outputs Using Kogna's RS485 Port. It is untested. Your example doesn't help much because the library functions weren't provided or documented. This table defines the Mod...
