Error: bad Command XXX W/RRF 3.2 and leveling issue

martin7404

My left tool head is V6 and is 2.55 mm different from the copperhead

martin7404

Just revert back to PRG 3.1.1 and it is the same
Start print the head (T1) prints on Z 2.55 on the screen of DWC and is about 2.55 in the air. So just like there are 2 offsets applied one over the other,
One of them is just like you made it in the slicer.
One more thing using babysteps it changes the dimension on the DWC screen If I do - babysteps the screen Z goes up . It is the same with PRF3.1.1 and 3.2

oh, sorry I forgot that you had one V6.

3DPrintingWorld

@martin7404 Can you verify in the G-code that they should be printing at the same height?

Here is the beginning of the code

@martin7404 Should the offset be negative instead of positive? Sorry I'm not sure which one is longer, or shorter.

martin7404

I am not quite sure, but in manual, I do tool change and on 10.5 Z my gauge is spot on. I tested the right extruder month ago, but with changing the system ofset. When negative it is not right. Looking at e3d tool changer it is negative, you might be right

martin7404

@3DPrintingWorld The V6 is shorter, otherwise, I would make them equal in Z. I hate that thing with tools and the Z shown on the screen since old Fanuc millnig CNC controls. Exactly why for tooling work I do not use length compensation and just switch the WCS (G54 , G55 etc) for each tool

3DPrintingWorld

@martin7404 Yeah, I think you would have a hard time trying to find 2.5mm to remove from the height. When I switched from the nimble to the BMG I really fought to keep the extruder as low to the bearing as I could.

martin7404

@3DPrintingWorld The problem for me is that there is no info how duet handles tool offsets I made it successfully on Dual lifting hotends but it was on PRF 2.5 and the moving extruder was longer

3DPrintingWorld

@martin7404 According to this you change the offset of T1. This tells me that the number can be positive or negative because otherwise you would have to modify T0 offset if the number was negative.

martin7404

@3DPrintingWorld thank you
I still do not see what I am doing wrong

3DPrintingWorld

@martin7404 so making it a negative number didn't help?

martin7404

@3DPrintingWorld I am remote to the printer IT is in the shop and I am at home and I am afraid to test it on the camera

3DPrintingWorld

@martin7404 To be safe you could change it to a negative on the T1 offset then add 2.55mm to your T0 probe offset.

martin7404

@3DPrintingWorld I am printing it now with 5 mm offset from the slicer

3DPrintingWorld

@martin7404 Got it! You are doing it differently but I just wanted to clear up what I said, to add to the probe height you would actually have to subtract.

martin7404

YES and I canceled it , because slicer offset do not affect the priming
