Buffer using LIFO ? #43

Closed mzi1sk closed 8 years ago

mzi1sk commented 8 years ago

Hello, i am getting problems with command order. If I understand correctly buffer works LIFO(last in first out) method. I would need to process it FIFO or if you can give me any hit for workaround. Thank you

this is the log

No, it's a FIFO queue. It definitely does not jumble order as this is used heavily by thousands of users on CNC jobs. Can you explain better how/what you're seeing with things getting out of order? It is more likely you are sending stuff out of order.

Ok thank you for fast responce. I will investigate more, why it gets mixed. Thank you for now.

Hello all. John is it possible that we receive the packages in the wrong order I have had a similar problem seems to be network related as the packet flow had latency? I was definitely processing out of order. Not sure of the cause-and-effect analysis... FYI I have found its useful to send coordinate system or otherwise set up file to the tiny G in my case almost every job this in a batch file right now I execute it manually but would like to automate this process

This really seems to streamline the process always have a successful run no velocity problems And stepper issues!

Thanks again John for all your support to the community

solution for me was using parameter Pause:100

messages gets mixed during json-server processing them on COM3 port How I monitored it : 1) checked the order of ws messages on chrome using dev tools - network - ws ; order was OK 2) checking on http://localhost:8989/. I see order of messages going to que is OK , I used ID's to identify them , and they were also processed OK.
3) using free serial monitor soft. I see messages got mixed order here. It must be caused by speed of my device (accept only 9600Baud) as I said solution was using pause parameter.
