I think I would like it cleared when the print completes. If you need a permanent change add or subtract the baby steps just used to homed height so the next print doesn't need to be stepped. If you print the curreent baby step offset before clearing it the user can go to the console and see the value. Thius way forces you to update your printer if you needs baby steps. What I really would like to see is the mesh correction appllied at each location diisplayed..

After I loaded the height map m122 shows all z probes points as zero. Is that bad?

What is an easy way to test if I need a new display or a new PanelDue? I thought of installing Atmel Studio and finding a helloworld example for an LCD. I've even worked with GLCD on other platforms so it shouldn't be too bad since I have your source as a reference. Thanks for replying. This may be a dumb question, but can I use a Raspberry Pi 7" touch screen? The ribbon connector is wider than the one on the 4.3, but I think that may be due to resolution. With the new PanelDue board of course.

I may have moved the jumper, or shorted the the 4 connection pins. I can reflash the firmware with no errors, but get only the screen backlight. Is there any way to test the panel due board to determine if I killed it or the display? I have a 2.3" TFT that is 240x320, it also shows only a white screen. Sorry to bother you with a problem I caused. I don't want to replace the Panel Due and find out the TFT is dead. The Due board looks like it has some kind of debug or flash onnetions labeled X4.a

Yes, I\m going through the doumentation again tonight following all the steps for G32 and G29. I\ll post the map details when done. I think missed a step. My height map was almost perfect, but after clearing mesh compensasion is off by over 2mms in one corner. If you don't explicitly clear prior compensation can the values stack up?

Before printing I run a calibration and a new mesh probe. However, my first layer is never consistent. Some areas are not printing low enough for good adhesion, other areas are too low and only a smear is printed. I have manually leveled the bed so there is less than 0.3 mm difference in the highest and lowest spot, but I can't seem to get a consistent first layer. If I run G29 S0 then print a simple square should it print smoothly, with the same amount of squishing ( technical term) of the filiment into the glass? Am I missing something? I'm using a smart effector so tilt should not be an issue.

I tried static, sending m552 s0, setting the ip to a valid one , then m552 s1. setting the IP to all zeros,then m552 s1. Nothing worked at all. On a hunch I grabed an old lynksys router and connected my printer and laptop to that. Of course it works just like it should.
5260
There is an obvious problem with Spektrum's newest offering, the Sagecom Fast 5260. I found a reference to some MAC addresses being blocked, but no place to block a MAC address, or even really view a log file. I'm using my router from now on. Thanks for replying. I was totally lost until I searched and found the commands to send to test my network. based on what you had me send.

I also figured out the ABS heating issue. It was heating fine, I had the wrong steps per mm for my extruder and had never calibrated the ADC on the duet.

I still get a 4mm z offset from somwhere when running mesh compensation. all probee values are 4.XX instead of 0.xx. weird.

i upgrqded the firmware, now I an't get a network connetion at all okI tried looking in my router logs for errors, but don't see anything. Pronterfae is urrently on Ubuntu, and my windows partition wasn't found today. I have been running screen but don't know how to force an attempt to connect. I saw some diagnostic commands from Chris somewhere. Hope I can find them. BTW, can DWC be run from USB? There should be an alternternative that really works for linux. Maybe I can get screen to work properly, with echo and formatted output.

I think I'm still on 1.21rc2 firmware. One thing I have noticed is DWC will still run without a connection from the browsers cache, which could be confusing. Refresh your browser and DWC can't connect either. I have tried DHCP and a static IP, but only DHCP after changing the MAC address works for me. Are there diagnostics I can log or run?

Also, somehow I get a 4.000mm offset for my Z access when running bed mesh compensation. Every probe point shows a 4mm shift upwards. My G31 has Z0.22, and the only reference I see to a 4 is the M558 probe height. I will post my config file as soon as I get a network connection or go get the SD card again.
