RE: 2nd independent Z-Axis labeled V Homing failed
@o_lampe There are 2 motors on each z axis and 1 motor on each Y axis I actually got this to work as fine as homing and moving correctly. I found a way to home both Z axis by adding the commands to the homez.g. What it does is first map the first Z axis with the first 2 motors then it remaps the 2nd Z axis with the other 2 motors and after it's done it combines all the motors into one Z axis motor.
It would be my goal to have both tools to extrude simultaneously on the same part so that basically it would cut the print time in 1/2. The chassis that I need to build for autonomous vehicle is divided into 3 parts and 2 of these parts took about 4 days to print -this was on a printer I bought but was very disappointed with it. I then decided to build my own.

RE: Bigtreetech smart filament sensor trigger2.g or trigger3.g
@nurgelrot to test it I cut the filament, activate and heat up the hot end, and then extrude till all filament runs out. which should pop up the message. I am using RRF3.3RC2.

RE: Understanding Height Maps
@fcwilt Yes, both X axis can travel the full length of the Y axis bed. Currently I am focusing on getting one tower at a time to generate a relative good print, then I will try to get the other tower to do the same with different filament.

RE: The right Z tower X motor always need to run M999
@fcwilt There can only be one independent Z axis at a time, that's why I switch the motor config to go to one or another. Would be sweet if two independent Z and X axis could work at the same time on the same print, thus cutting the print time in 1/2.

@fcwilt The macro switches between the two or joins them back:

RE: stop print and go to previous -Xsteps
@dc42 OK, wait a minute, where is the GCode viewer? Is this a plug in to the web interface? Definitely something to download and install. does the GCode viewer provide the GCode that is currently being executed in real time? This could save a lot of bad prints.

RE: Extruder direct drive gears clicking noise
@phaedrux OK, thankyou, I have not done an extruder calibration test, just used recommended flow rates and such...

RE: Extruder direct drive gears clicking noise
@th0mpy It works for a good while before starting to do this, originally I had the filament runout sensor put inline with the filament right before the extruder, which caused pressure on the filament and also the way I had the filament run to that point at times it was pretty tight between the extruder and the filament roll. Fixed that issue which improved the print tremendously, The clicking noise persists. this is the E3D Titan Aqua which keeps it really cool, this is a water cooled system. I pause the print and do a extrude test and it extrudes just fine, no clogging. The only thing that I do not have set up yet are the blower fans to cool off the extruded filament. But I need to print a mount for it first.

Extruder direct drive gears clicking noise
Progressing on with the build and now when extruding I am hearing a clicking noise. I see the larger gear advancing one notch but then it doesn't advance to the next notch, it just sits there clicking. Not sure what could be causing this. This doesn't happen right away into the print, this happens at 4 or more hours into the print it corrects itself and continues and eventually it happens again. I tried to alleviate all the pressures from pulling the filament so that the extruder drive makes less effort in pulling the filament. This seemed to have helped, but not 100%. The other option is the small metal knob that makes the gears tighter against the filament. I will try loosening this I already reduced the amps to 800mA. Does anyone have any suggestions? thanks.

stop print and go to previous -Xsteps
How is this best done? With G-code o C/C++ ? I mean in reality I can see that this would benefit all. I would like a way to pause a print and click on a map of the print, and have it restart from that point clicked on the map.

RE: Extruder stops in the middle
@phaedrux OK, that actually makes sense. I will check when I get home, but for the extruder motor its a NEMA 17 I think I have it set at 800mA or 1.2A..
