[solved]

I have a very short ptfe betwee bondtech and e3d heatsink. Turns out I had used the wrong nozzle size.. I installed 0.25mm and when slicing I set it as though it's a 0.3mm nozzle… This result in too much pressure in the ptfe and bondtech never slips so it pushes down the e3d hence giving me false thinking that the z tower on right side appear to struggle...

Turns out it's mechanical issue… I was pulling the belt too tight that the z leadscrew was binding...

I added G92 Z0 before homing z and seems to solve the issue.

in a very strange work around. I actually managed to get it to work. both print head print at the correct first layer now and more importantly same height

since my G31 has z offset of 0.15 all I did were:

update my homez.g after T1 touches FSR instead of it goes up 5mm i changed it to 5.15mm ( I kept T0 go up at 5mm) After homez.g finish running, I ended up with Z5.30. now if I print this way I will end up with the issue I started this post with. so I went to console and did G92 Z5.15

then problem solved although this seems like a band aid solution…

thank you I did reverse the order but also found out that in S3D I process T0 first and then T1 then T0 would heat up first.

I accidentally process T1 first and then T0 and it would heat up T1 first…

I guess I will try M116

Thanks; but it was Adrian Bowyer who designed that feature and did the initial implementation, not me.

yeah I swapped it with the 1st toolhead connector and 2nd toohead thermistor now reads normal. checking for bad wiring….

You will need to connect the JohnSL board to either E1 endstop input (M558 P6) or the Z probe connector (M558 P5) instead.

well that works. I used M558 H parameter method. not sure if I need to keep the X and Y parameter as well…

here's my homez.g revised

From left to right :

0
0.2
0.4
0.4 with jerk doubled (10 -> 20mm.s⁻²)

The in/out angle is the top right.

The default folder that M98 looks in is /sys. If you put your scripts in /macros or anywhere else, you need to specify the path to the file in the M98 command.

This is exactly what I was looking for

Will that be implemented in future firmware? I think it would continue to build upon the idea of U map to X and V map to Z

Thanks,
Stephen

your theory is sound. I will definitely give it a try. me being new to duet will have a lot to catch up on reading… thx

yeah I don't intent to do simultaneous printing. I'm mostly interested in the PLA - PVA combination and I believe IDEX is the way to go. I may actually commit to duet 🙂 thx
