@jay_s_uk Thanks! A simple fix indeed.

Followed the official Duet3D CNC pendant documentation to set up using Arduino Pro Micro. I have verified the communication with a Duet 3 Mini 5 by using the emergency stop button. Only the encoder is not responsive. I have make sure to connect both +5V from the 4-core cable and +5V for the encoder to the VCC terminal.

Is there a way to troubleshoot the issue?

@adhanabal Any updates on this?

@mfs12 Moved relevant files to VSCode toolkit directory solved the issue.

Using default build system

$ cmake -B build -DDEVICE="v3-7.0" .
$ make -C build all -j12

Is there a way to build PanelDue firmware with VS Code? So far I am unsuccessful with the below errors.

Any updates?

@dc42 Just updated to 3.5.0 beta 4. M950 Q5 works normally at heating the bed. But when M303 tuning, DWC will still go into a reconnect loop. Below is the diagnostics after reset.

Auto tuning heater 0 using target temperature 60.0°C and PWM 0.85 - do not leave printer unattended

@dc42 It is an AC silicone bed heater (240V supply voltage and 50Hz) with a DC-AC SSR.

@T3P3Tony No issues on DWC or PanelDue when heating bed. Do note that the low PWM does not work, the bed does not heat up until a heater fault occur which a reset is required.

P/S

M950 H0 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0

Did a few test with different PWM ie Q5, Q10, Q100 all did not work in my case, bed does not heat up, auto-tune causes DWC to go into reconnect loop. Without the Q parameter all is normal.

This maybe related to the recent post 3.5.0 beta 3 minimum PWM frequency. Issue as stated in title. Below are the details of the hardware & logs. Bed heater is driven by SSR with 5Hz PWM frequency at max PWM of 85%.

I am unable to issue M122 command as DWC is practically unusable. Physical reset is required.
