HI , I also have a duet wifi2 and just got my self an LIS3DH to try out, I was wondering if it was possible to use other pins then the temp board pins as it is in use already .
I do not use a screen or so .
thanks in advance for the help
Best Regards
Manuel
Dear DC42
in my mgs I was referring to E jerk, I use E400 with pa enabled and it is skipping steps but not in an extreme way, if I disable it no skipping steps. I normally use E1000 a E1500 without pa and working well but with pa I get extreme step skipping
my Xy Jerk are tuned to have almost no ringing "X900 Y900" I can go to 1200 but then very small ringing start appearing .

Dear
I was also trying to tune Pressure advance, I also noticed steps being skipped , I did many testing with many different configurations , My conclusion is that PA is skipping steps due to a much to high acceleration on short segments , on a cube of 50x50x50 for exemple I saw no skipping steps but as soon as I use a different model with circular and a grove “ for example 6mm in diameter with a grove intersecting with the circle” I start to get losses in steps if I increase my jerk by a lot I get a much reduce loses of steps , but then the other models get under extruded at some places.
I hope it can help, cause it would be nice to have it working optimally, the shape corners get a much nicer with PA

Dear Jacksat
Very nice build !!!!! I also thought of using a much bigger airpump , but the cost is fairly steep , after all the testing I did , using compressed air is best for small parts as for biger parts the fans work beter of course it depends how much air you have available , during my testing i managed to use both and that gives really nice result , quick cooling near the nozzle and even cooling on the rest of the part .
I really like you water cooling , you have a much heavier build then me , I used the same material as the ultimaker 2 to build my printer , it s a much lighter build ,
Do do have an idea how much extra weight it adds on the head ? And do you get resonance to the frame from those big fans from the cooling bloque ?
I am asking cause for my build i opted for to have as light as possible heads since I use belt drives that is the reason I added the magnetic tool change in the 1st place , after tying many printer from my friend and so I figured out that ultimaker got very nice and repeatable prints , I figured that one of the reasons is the lightnest of the axes and head
I am not sure but from ur pictures looks like I using like a buildtalk on you table , I am wondering how good is the result with the dc42 ir prob ? I am using the prob and got a buildtalk plate but have not tried it yet

Once again you are right got over exited to have my printer working again , and was to quick to post,
pls accept my apologies
Thanks again for your support

Dear DC42
I found an other issue , if I cancel a print the tool change macro are not being executed
to better explain , if I cancel a print and a tool is still loaded , I and I click on the tool to put it back in standby and go back to its parking place , I get no responds

I have tried some similar approach some time ago without much success I was clogging my nozzle 2 often with the retract , then I just dropped it. since I have limited time for my hobbies 
If you don't mind could you post some picture just for my curiosity
Best Regards
MT
Ps if you intrested something I have tested with great success ,the use of compressed air for cooling the part during printing , for small part worked miracles only problem was the amount of air used and the noise, my neighbor became crazy , the compressor was working to much and for to long :-). so reverted to the traditional fan,
the advantaged was less weight on the head and vibration was reduced ,not that there is a lot of vibration , but any improvement is an improvement how ever small
foehnsturm
do you use something similar to mark2 for your tool change ?
Best Regards
MT
Dear DC42 & foehnsturm
Seems foehnsturm is correct !!
I have tried to add the last line of tpre1 2 times and it seems to work
If I may ask what slicer are you guys using ?
thanks to both of you
Best Regards
MT
Dear foehnsturm
I am also using a magnetic tool change , with the 1.18 firmware I can confirm that all is working well ,
I never managed to get 1.19 working ,since I always had the wrong tool active. did you experience something similar ?
The issue with wrong tool being active got solved with the latest 1.2 beta4 but I am still facing some issues with the tpre file as it is not fully executed.

Dear DC42
just to see what happens I have let the printer continue to print
the behavior is as follow
start printing
T0 is loaded waiting till it reaches temp , start 1 layer
T0 is parked Tfree fully executed
T1 is in the process of being loaded the gcode executes to the 5th line of the tpre, and stops there
then remains there till the nozzle reaches the temperature ,
once the temperature is reached it continues to print , without the tool being loaded , but the tool is active like it should .
once the layer without loaded tool is completed it executes Tfree1 successfully
Then execute tpre0 successfully and tool0 is correctly loaded wait for temp to be reached and start printing.
hope it will help u to find the glitch
Best Regards

I have put back the 1.18 firmware and the switching is back to normal no stopping at T1 command
you are right
the ; was missing , but it has always been missing cause I did not edit the file
the error msg is gone but the stop in the middle of the tool change remains on T1
T0 is being parked and collected correctly
but when it goes back to collect tool1 seems that to stops before finished and immediately wait for the tool to get to temp then continue printing but the tool1 is not loaded
Thanks
Best Regards
Manuel Topiol
I will check right away
Dear DC42
There is some improvement and possibly resolved !!!!
I just updated the firmware as per previous msg
tried again the tool change, the problem of the 1st boot and T0 command disappeared, then I did a T1 command and I got an error MSG Error: Bad command: Lift Z relatively to current position
I removed the Z lift command and now when I change tools the correct tool is active
some thing strange is that the z lift is the same in pre0 then in pre1 but the error is only appearing in T1

for info
Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.20beta4 (2017-10-28)
WiFi Server Version: 1.20beta2
Web Interface Version: 1.19.3
best regards
Dear I have done the update of the firmware per your request
Situation is the same with a slight difference
now when I select tool 0 from a fresh machine boot , it doesn't complete the full tool change, the gcode file is not fully processed,
as opposed to before I could just type T0 and it will collect the tool without problem .
after I put the T0 back in standby and do an other T0 I will get it correctly ,
then I do a T1 command and it will fetch tool1 but after the selection is complete T0 is set to active.
, I feel strange, for sure I am not the only guy owning a duet wifi with a tool change, but no one else is complaining about this problem
