How about a separate PSU for the heater(s) and use the second hot end mosfet to control a DC to DC SSR. That way you can also use the thermister port for the second hot end and have full duet control.by jbolt - Duet
I'm using four 12mm rails on the Z of my 400x400x400mm build area CoreXY, also based on the HyperCube Evo. Easy enough to align. I'm using a single motor and belt to drive both lead screws to eliminate any timing issues. Without the Stepper motor attached to resist the lead screws the Z assembly will fall under its own weight, no binding. I have not checked the parallelism of the X rails but I dby jbolt - CoreXY Machines
I have the bed mesh configured and it probes the bed correctly. Question, after running G92 how does the controller know to use the current height map during a print? or do I need to add G92 S1 to my start script or?by jbolt - Duet
My bed is 1/4 aluminum so it is clamped to the back edge similar to the example in this thread, fourth post down.by jbolt - Duet
(UPDATE) Disregard, I figured it out. I have the printer tuned pretty good now. I'm getting the best prints I have ever done with PETG. I love how easy it is to adjust the setting on the Duet. One of the last remaining bits is the bed mesh. For a CoreXY printer do I put the M557 in the bed.g file or in the config.g file? Does G29 need to be in either of these files? Are there any other M orby jbolt - Duet
No I have not set a static IP. When the board won't connect I can query the IP address in Simplify3D via USB with M552 and it will show the router assigned IP but will not connect until I remove the 24vdc power. I am also using the recommended USB isolator for ground loops. I prefer not to have the USB hooked up at all since it applies power to the board when the main power is off.

I'm using a NTE8182 thermal fuse with a 192c cutoff. It was recommended by others to stay away from the no-name imports from China due to inconsistencies.by jbolt - Duet
Yes I am running a thermal fuse.by jbolt - Duet
The IP address is there it just won't connect unless under USB power only. Even after resets my router has been assigning the same IP address. I'm not using the PanelDue. I will take a look at M552by jbolt - Duet
Is it correct to say that if the PID tuning (at whatever PWM% I chose) is stable, I use those PID values and rely on the thermal protection I am comfortable with in case of a fault, regardless of the warning?by jbolt - Duet
When I first powered up the Duet Ethernet it would not connect to the web control with the board powered by the 24z power supply. It would only connect under USB power. After that it connects fine with just the Ethernet cable attached and under 24v power (no US. Today I had to reset the router and again the board would not connect to the web control. I had to power off the board and attach the USby jbolt - Duet
What is the relevance of the over-power warning during PID tuning? I have a 400mm x 400mm x 6.35mm MIC-6 aluminum plate heat bed with a 110vac 1200w Keenovo heating pad. The purpose being for quick heat up. At 100% PWM the heat time is 2-1/2 minutes to 80c from ambient (20c) but I get an over-power warning. On the PID tuning I decreased the PWM percentage by 0.2 increments until I no longer gby jbolt - Duet
That was it. One motor was 0.9 and the other 1.8. Supplier had a motor mis-packaged. I never bothered to check the model numbers before installing. Stupid me. Now on to calibrating each axis. o_lampe - thanks to that catch. That came from the configurator. I'm not even sure what it is supposed to be. Still learning!by jbolt - Duet
I marked the motor shafts and they don't move the same amount so I checked the model numbers and they do not match so I may have been sent mismatched motors.by jbolt - Duet

Here is what I get. M667 Printer mode is CoreXY with axis factors X:1.000000 Y:1.000000 Z:1.000000 M669 Error: M669 parameters do not apply to CoreXY kinematicsby jbolt - Duet
Config is set to M667 S1 CoreXY mode. I have the motors moving in the proper directions per the Duet CoreXY configuration instructions. Each axis homes in the correct direction when commanded to move but when one axis is commanded to move the other axis also moves? Also when I home X the Y also moves in the + direction. When I home Y the X axis also moves in the + direction. X & Y home areby jbolt - Duet
Thank you for the response. I have the board working. It did not play nice when the USB and Ethernet cables were attached at the same time and under 24v power. Once the configuration files were setup and the board rebooted under just USB power it started working.by jbolt - Duet
I pulled the board from the printer and plugged in the USB with the board on the bench. Nothing, it would not show up in device manager. I noticed the USB powered hub was not showing a connection for that cable so I plugged the USB cable directly into the PC. It now shows up in the device manger. I plugged in the network cable and queried the router for the IP address which it returned. I am nowby jbolt - Duet
I'm commissioning the board and as best I can tell the SD card slot is not working. I can read the SD card when directly connected to the PC and all the files seem to be there . M122 shows no SD card detected. I tried a different SD card with the same result. I added a gcode file to the gcode folder and ran M20 and it can back empty. I can connect to the board via USB through simplify3d or Arduinby jbolt - Duet
