Driver numbers?

Are you saying that changing which outputs the Z motors are connected to has stopped the X and Y endstops from terminating a G1 S1 X or G1 S1 Y homing move?
If so, is this a Cartesian or a CoreXY machine, and are you using Duet WiFi or Duet Ethernet?

Clockwise reconfiguration worked, 4 axis autolevelling of the bed is now working (i also upgraded to 1.20)! thx!!
Just one more question for the night:I was using M557 X0:310 S310 Y0:230 S230 before and that did a nice asymmetric 4 point scan of the bed for the heightmap.
After upgrading it stopped after the second point and said too few point for cheightmap… so i tried a smaller spacing like this:
M557 X0:310 S155 Y0:230 S115 which did the trick, only that I get a six point mesh instead of the expected 9 point now.Should be nine points right at positions X0:155:310:155:0:155:310 Y0:0:0:115:115:115:230:230:230 right?
Limits are
M208 X310 Y230 Z225 ; set axis maxima
M208 X0 Y0 Z-1 S1 ; Set axis minima -
Your Z probe X and Y offsets also affect how many points will be probed, because they may indicate that some of the extremeties of the grid defined by M557 are not reachable by the probe.
-
X, Y and Z offsets are set to zero for the time being, doesnt help. I also played with the limits settings, doesnt help either.
Am i missing a typo here: M557 X0:310 S155 Y0:230 S115? It is probing both directions with a 155mm spacing.
If i say M557 X0:310 S100 Y0:230 S50, it is probing both directions with a 100mm spacing, obviously its ignoring the second S parameter when i run the "mesh grid compensation" function of the Duet web interface (initiating the G29 command). -
You can't use two S parameters, but in firmware 1.20 you can use for example S155:115 or S100:50. The first value is the X spacing, the second is the Y spacing.

Bed levveling is working smoothly now to the next step: The chamber heater is built, a radial fan and 2x50W heat cartridges (not too much power but we will see how warm it get in there in combination with the heatbed). Using an external power supply at 24V 3A (cartridges wired in parallel) it levels at about 90°C with the fan blowing at a decent amount of air through it. However trying to power it via E2 on the board, driven at 24V too (450W power supply) it seems to be doing something but barley reaches 25°C when i set it to 50°C via the webinterface. So here is my configuration, is it waiting for the tool to heat up or something?
; Heaters
M141 H2 ; Assign chamber heater to heater 2
M143 H0 S125 ; set maximum bed temperature
M143 H1 S480 ; set maximum hotend temperature
M143 H2 S80 ; set the maximum chamber temperature
M301 H0 P-1 ; Set bed heater to bang-bang mode
M301 H1 P-1 ; Set bed heater to bang-bang mode
M301 H2 P-1 ; Set chamber heater to bang-bang mode
M305 P0 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for bed heater 0
M305 P1 X104 ; Assign TC daughter board channel 1 to H1 hotend heater
M305 P2 X201 ; Assign PT daughter board channel 1 to H2 chamber heater ;
M305 P102 X200 S"Chamber 2" ; -
Does it give a heater fault? You may need to tune it using e.g. M303 H2 S50 even if you intend to run it in bang-bang mode, to prevent the heater protection kicking in.
-
Naa its not giving a fault but yes M303 did the trick and thanks again!
-
Moin, finally finding time to continue on my printer… Opposite to my previous comment i found that i can only initiate the chamber heater directly after running the m303 autotuning routine. When the Duet is turned off and on again, the chamber heater does not respond (it says active but its not actually heating) when i set it to 60°C e.g. I have used the m500 command after autotuning.
thx

Do you have command M501 near the end of config.g, so that the M307 commands that were written to config-override.g get executed?
-
Thanks again!
