The G92 X0 Y0 may be messing things up. Please remove it, and use M208 to set up the positions at which the homing switches trigger instead.

Didn't change anything. Z still increases. It appears that Z increases by whatever value is in the heightmap for the XY coordinates at which the XY homing was triggered. In my first example, it kept increasing by 0.173 because I was moving to the same XY coordinates before each try.

The second issue of the extra 0.700 is really baffling and it's actually causing the nozzle to crash into the bed because the Duet thinks the bed is higher than it really is.

I'm a bit stuck. I use drives 2 and 4 for Z and for bed leveling, do I still need to use seperate M574 commands, and can I still used bed leveling ?

Do you really mean bed levelling (using the Z probe, see https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors), or do you mean independent endstop switches on each of the Z motors? Your config.g file isn't right for either.

gtj0

I think I solved my Z 0.700 issue. I don't know how but...

G31
Current reading 0, threshold 500, trigger height 0.70, offsets X0.0 Y0.0

Nowhere in my configs to I set 0.700 for anything.
Anyway, a restart seems to have solved that issue.
I'm retesting mesh probing and the heightmap thing now.

@dc42 bed leveling using the bed leveling probe (an ir sensor, one of yours )

gtj0

Yeah I still have the issue with the Z height changing when homing XY when a heightmap is in effect.

On my list to investigate, but may have to wait until after TCT.

No problem. I'll nose around a bit this weekend.

Odd one. Heater faulted halfway through a print. Print kept going, but shows 100% for a status (can't cancel it anymore). Obviously not extruding, just still moving. DWC went unresponsive on me, too. Really odd.
No idea why the heater faulted yet.

wilriker

@kraegar This means this issue has not been fixed, yet.

EDIT: which version of DSF are you using? That might make my above assumption incorrect.

Marco Bona

With this build I encounter problems with heater mapping. The values found are -273 with the exception of the heated chamber which is correct.

are you definitely using .cs1 and .cs2 not .cs0 and .cs1 (i.e you have one daughter board) also remove the second P value

T3P3Tony

@kraegar I recommend using DSF 1.0.3.3

Marco Bona

@t3p3tony
Sorry but the second P value was a bonding problem.
For DSF I realized that it was only for Duet3, I'm using Duet2. If it is to be installed where can I find the file?

T3P3Tony

@Marco-Bona No you are right DSF is only Duet 3

kraegar

@T3P3Tony Thanks - I wasn't pointing to the unstable repo. Also, easy fix, but might trip up someone not linux savvy, you're missing a sudo on the apt-get install line of the instructions.

kraegar

Failed again, at 14.50mm of an 80mm print. Reports it's 100% but definitely is not.

kraegar

I'd only used systemctl to restart all the duet processes. Trying a print from a known reliable slice from my duet2, with a fresh boot on the latest software on the unstable branch.
