attempting reconnect though it connected
-
Hi,
DWC shows below alert blinking every around 0.1seconds and then becomes uncontrollable status though it's connected(buttons are working but refreshing every 0.1seconds due to reconnection). It happened after I restarted the system after changing config.g file. Tried to use various method to fix but still not working.
alert : connection lost. attempting reconnect.
Console : Connection interrupted, attempting to reconnect... Unexpected token a in JSON at posion 560Could anyone help to solve this problem?
I'm using DUET2WIFI with DUEX5 for 4 extruders for 4color mixed nozzle and I just found there is some error on M567 according to M588(diagnose) but I don't know what's error.
Configuration is as follows.

What did you change?
What firmware version are you using? What version of DWC are you using?

Thanks for reply. I'm using below.; Configuration file for Duet WiFi (firmware version 2.03)
; executed by the firmware on start-up
; generated by RepRapFirmware Configuration Tool v2.1.8 on Mon Mar 30 2020I tried testing two DWC version such as DuetWebControl-SD-3.1.1 and also old version but same alert happens. I changed below.
M92 X106.67 Y106.67 Z800.00 E984.00:984.00:984.00:984.00 ; set steps per mm
M566 X1200.00 Y1200.00 Z100.00 E3600.00:3600.00:E3600.00:3600.00 ; set maximum instantaneous speed changes (mm/min) jerk

M906 X1500 Y1500 Z1500 E450:450:450:450 I30 ; set motor currents (mA) and motor idle factor in per centI largely expanded maximum speed and acceleration and jerk and then removed decimal numbers(ex : M203 X36000 removed .00 now returned as 36000.00 as above but still same).
Tried remove M552 S1 then it was not connected network so revived.
Machine is working if I press "Home All" button but cannot edit system file as it refreshes continuously.

I'm not really sure what could be going on. But I think maybe there is a version mis match. You haven't actually said what version of firmware and DWC you are using, but I suggest that you try upgrading to version 3.0 and then 3.1.1. Use the web config tool to get a fresh config set for v3.
