I run a BLtouch.

I would like to automatically re-calibrate the Z-offset of the BL Touch.

Can i first Z home the bed first by using the motor stall function on Z axis,
then re-home Z axis using the BL touch.
The resulting difference should be the exact Z offset for the BL touch.
This should all be able to be done in a Macro i believe.

This would involve setting z endstop to motor stall, the on second pass setting endstop to bltouch.

What is the default max z travel during mesh leveling?

Is it possible to increase the z travel before i get leveling failed error or probe not triggered?

For some reason my Fan0 F1 and Fan 2 connectors do not drive fan.

I do have a Duex5, so i have F3,4,5 etc available.

I am trying to work out how to remap Fano to Fan3 Pins.

Everything i have tried either gives me multiple Fan control on DWC.

Even assigning tool to F3:0,

send a gcode Fan0 does not control Fan3.

Any suggestions on this please.

Will there be any provision for PT100 or K type sensor inputs?

yes with 4 wire cable.

its not the baud rate.

swapping board out tmr and see whats going on.

I can talk to the maestro vis usb/com using YAT.
But the display always says connecting.
triest another 5i display, same result.

anything else to try?

P.S. Have also used Bossa to reload firmware.

Any Help here. i can seem to read the onboard thermistors after i have the PT100 allocated to the Hot ends.

For the time being i have my chamber fan turning on after the Bed gets to 130 Deg C.

I am trying to setup a Chassis fan to suck out air from enclosure once the ambient enclosure temp exceeds say 65degC

I have this setup as i am using PT100 sensors

M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S160 ; Set temperature limit for heater 0 to 160C
M305 P1 X201 ; Configure PT100 for heater 1
M143 H1 S430 ; Set temperature limit for heater 1 to 430C
M305 P2 X200 ; Configure PT100 for heater 2
M143 H2 S430 ; Set temperature limit for heater 2 to 430C
M305 P3 T100000 B4138 R4700

Fan control something like this

M106 P2 S0 T65 H3

as using P2 Fan output.

I wish to use a normal thermister on say E0 thermistor input as its not used due to PT100 Board

I was playing with the M305 command to setup parameters for thermistor

Is there a simple way for the M106 commane to read the thermistor channel, do i need to create a tool?
What have i missed?

some help would be greatly appreciated.

I had this model printed on my main printer and got this thicker back appearing on surface.
i then turned on pressure advance and print great

i got a second printer that had a marlin board which printed the same model fine.
installed duet, and printed the same band.
so i turned on pressure advance, but the band is still there.

all printers are direct drive.
just can figure it out, any suggestions?
